  abstract  = {Brain-computer interfaces (BCIs) enable paralyzed patients to communicate; however, up to date, no creative expression was possible. The current study investigated the accuracy and user-friendliness of P300-Brain Painting, a new BCI application developed to paint pictures using brain activity only. Two different versions of the P300-Brain Painting application were tested: A colored matrix tested by a group of ALS-patients (n = 3) and healthy participants (n = 10), and a black and white matrix tested by healthy participants (n = 10). The three ALS-patients achieved high accuracies; two of them reaching above 89\% accuracy. In healthy subjects, a comparison between the P300-Brain Painting application (colored matrix) and the P300-Spelling application revealed significantly lower accuracy and P300 amplitudes for the P300-Brain Painting application. This drop in accuracy and P300 amplitudes was not found when comparing the P300-Spelling application to an adapted, black and white matrix of the P300-Brain Painting application. By employing a black and white matrix, the accuracy of the P300-Brain Painting application was significantly enhanced and reached the accuracy of the P300-Spelling application. ALS-patients greatly enjoyed P300-Brain Painting and were able to use the application with the same accuracy as healthy subjects. P300-Brain Painting enables paralyzed patients to express themselves creatively and to participate in the prolific society through exhibitions.},

  abstract  = {The aim of the present thesis was to explore how food deprivation and reward expectancy versus frustrative nonreward change implicit and explicit food-liking and food-wanting. As a result, Experiment 1-3 were successful in revealing that liking- and wanting-related associations toward food stimuli dissociate as a function of food deprivation, given that participants were not rewarded with real food during the experiment. More specifically, whereas food-deprived participants showed more wanting-related associations toward food stimuli than satiated participants, the liking-related associations did not differ across both conditions of hunger. Overall, this effect could be replicated in 3 experiments using different manipulations of nonreward versus reward expectancy. However, neither food deprivation nor nonreward were found to influence participants' self-reported mood and frustration. Moreover, participants of Experiment 2 anticipating food consumption showed the same liking- and wanting-related responses due to food deprivation than participants in the nonreward condition. But providing participants with individual control over food consumption abolished the dissociation of liking- and wanting-related associations. In this condition, however, participants' liking- and wanting-related associations were not moderated by need state, maybe due to the (partial) consumption of snack food before the implicit attitude assessment. This, in turn, may have reduced participants' disposition to respond with more liking- and wanting-related associations when being hungry. Finally, Experiment 4 revealed that the presentation of need-relevant vs. need-irrelevant stimuli prompted different liking-related associations depending on the time participants had fasted before the experiment. Specifically, it could be demonstrated that whereas moderately-hungry compared to satiated participants responded with more positive associations toward need-relevant stimuli, 15 hours food-deprived participants responded with more negative associations compared to moderately-hungry and satiated participants. Respectively, a significant curvilinear function of need state was obtained. In addition, participants were found to immediately respond more negatively to need-irrelevant stimuli as soon as they became moderately hungry, evidencing devaluation effects (see Brendl, Markman, \& Messner, 2003) to also occur on an implicit level of responding. Contrary to the implicit liking- and wanting-related evaluations, self-reported explicit food-liking and food-wanting did not dissociate as a function of food deprivation and nonreward, revealing that participants' explicit self-reports of food-liking and food-wanting did not mirror their implicit responses. As the most important result, it could be demonstrated that explicit food-liking and food-wanting varied positively as a function of need state. The results were discussed on the background of different theoretical assumptions on the malleability of implicit and explicit need-relevant attitudes (e.g. motivational theories, frustrative nonreward).},

  abstract  = {Neuroplasticity is a term indicating structural and functional changes in the brain through the lifespan. In the present study, differences in the functional cortical activations between the musical talents and non-talents were investigated after a short-term practice of the visuomotor and auditory tasks. Visuomotor task consisted of the finger tapping sequences, while auditory task consisted of passive listening to the classical music excerpts. Non-talents were divided in two groups: trained non-talents who practiced the task prior to scanning and untrained non-talents who did not practice the task. Functional activations were obtained by the functional magnetic resonance imaging (fMRI) in a 1.5T Scanner. It was hypothesized that talents would exhibit different functional activations from non-talents in both tasks as a result of the long-term music practice, which would account for the brain plasticity. Decreased activation of the same areas in talents in respect to the non-talents as well as the activation of different areas between the talents and non-talents was hypothesized. In addition due to a plethora of previous studies showing increased activations in the primary motor cortex (M1) in musicians, as well as left inferior frontal gyrus (lIFG), increased activation of the M1 and lIFG in talents were hypothesized. Behavioral results did not reveal differences in performance among the three groups of subjects (talents, non-talents who practiced the task, and non-talents who did not practice the task). The main findings from imaging results of the visuomotor task confirmed the hypothesis of the increased activation in the M1 in talents. Region of interest analyses of the lIFG revealed the highest activation in the untrained non-talents, lower activation in talents, and least activation in the trained non-talents. Posthoc imaging analyses revealed higher activations in the cerebella of subjects who practiced the visuomotor task. For the auditory task, the effect of auditory practice was observed in the right inferior frontal gyrus (rIFG). These results should be interpreted with caution due to the absence of behavioral differences among the groups.},

  abstract  = {In order to unify two major theories of moral judgment, a novel task is employed which combines elements of Kohlberg´s stage theory and of the theory of information integration. In contrast to the format of Kohlberg´s moral judgment interview, a nonverbal and quantitative response which makes low demands on verbal facility was used . Moral informers differing in value, i.e. high and low, are presented. The differences in effect of those two pieces of information should be substantial for a person at that specific moral stage, but small for a person at a different stage. Hence, these differences may diagnose the person's moral stage in the simplest possible way as the two levels of each of the thoughts were about typical content of the four Kohlbergian preconventional and conventional stages. The novel task allowed additionally to measure the influence of another moral concept which was about the non-Kohlbergian moral concept of recompense. After a training phase, pairs of those thoughts were presented to allow for the study of integration and individual differences. German and Korean children, 8, 10, and 12 years in age, judged deserved punishment. The patterns of means, correlations and factor loadings showed that elements of both theories can be unified, but produced unexpected results also. Additive integration of each of the two pairs of moral informers appeared, either with two Kohlbergian moral informers or with another Kohlbergian moral informer in combination with information about recompense. Also cultural independence as well as dependence, developmental changes between 8 and 10 years, and an outstanding moral impact of recompense in size and distinctiveness were observed.},

  abstract  = {The aim of this project was to investigate whether reflex-like innate facial reactions to tastes and odors are altered in patients with eating disorders. Qualitatively different tastes and odors have been found to elicit specific facial expressions in newborns. This specificity in newborns is characterized by positive facial reactions in response to pleasant stimuli and by negative facial reactions in response to unpleasant stimuli. It is, however, unclear, whether these specific facial displays remain stable during ontogeny (1). Despite the fact that several studies had shown that taste-and odor-elicited facial reactions remain quite stable across a human's life-span, the specificity of research questions, as well as different research methods, allow only limited comparisons between studies. Moreover, the gustofacial response patterns might be altered in pathological eating behavior (2). To date, however, the question of whether dysfunctional eating behavior might alter facial activity in response to tastes and odors has not been addressed. Furthermore, changes in facial activity might be linked to deficient inhibitory facial control (3). To investigate these three research questions, facial reactions in response to tastes and odors were assessed. Facial reactions were analyzed using the Facial Action Coding System (FACS, Ekman \& Friesen, 1978; Ekman, Friesen, \& Hager, 2002) and electromyography.},

  abstract  = {Organismen vermeiden Gefahren und streben nach Belohnungen, um zu {\"u}berleben. Klassische Konditionierung ist ein einfaches Model, das erkl{\"a}rt, wie Tiere und Menschen Ereignisse in Verbindung bringen. Dieses Lernen erm{\"o}glicht Lebewesen Gefahr oder Belohnung direkt vorherzusehen. Normalerweise besteht das Konditionierungsparadigma aus der Pr{\"a}sentation eines neutralen Stimulus zusammen mit einem biologisch bedeutsamen Event (der unkonditionierte Stimulus - US). Aufgrund dieser Assoziation erwirbt der neutrale Stimulus affektive Eigenschaften und wird dann konditionierter Stimulus (CS+) genannt. Wenn der CS+ mit Schmerz w{\"a}hrend der Trainingsphase assoziiert wird, leitet er eine defensive Reaktion, wie z.B. Vermeidung ein. Wenn der CS+ mit einer Belohnung assoziiert wird, leitet er eine appetitive Reaktion, wie z.B. Ann{\"a}herungsreaktionen ein. Interessanterweise haben Tierstudien gezeigt, dass ein konditionierter Stimulus vermieden wurde, wenn er einem aversiven US in der Trainingsphase vorausgegangen war (CS+US; Vorw{\"a}rtskonditionierung). Das deutet darauf hin, dass der CS+ aversive Eigenschaften erlangt hat. Jedoch f{\"u}hrte ein konditionierter Stimulus zu einer Ann{\"a}herung, wenn er in der Trainingsphase auf einen aversiven US folgt (US CS+; R{\"u}ckw{\"a}rtskonditionierung). Das deutet darauf hin, dass der CS+ appetitive Eigenschaften erlangt hat. Kann das Event Timing sowohl aversive als auch appetitive konditionierten Reaktionen auch bei Menschen ausl{\"o}sen, die zu Kognitionen bez{\"u}glich der Assoziationen f{\"a}hig sind? Um diese Fragestellung zu beantworten, wurden vier Studien durchgef{\"u}hrt. Die Studien hatten den gleichen Ablauf, variiert wurde nur die Zeit zwischen CS+ und US (das Interstimulusintervall - ISI - ist als das Zeitintervall zwischen dem Onset des CS+ und dem Onset des US definiert). W{\"a}hrend der Akquisitionsphase (Konditionierung) wurden, zwei einfache geometrische Figuren als konditionierte Stimuli dargeboten. Eine geometrische Figur (der CS+) war immer mit einem leichten schmerzhaften elektrischen Reiz (der aversive US) assoziiert; die andere Figur (der CS-) war nie mit dem elektrischen Reiz assoziiert. In einem between-subjects Design wurde entweder eine Vorw{\"a}rtskonditionierung oder eine R{\"u}ckw{\"a}rtskonditionierung durchgef{\"u}hrt. W{\"a}hrend der Testsphase (Extinktion) wurden CS+ und CS- pr{\"a}sentiert sowie zus{\"a}tzlich eine neue neutrale geometrische Figur pr{\"a}sentiert, die als Kontrollstimulus fungierte; der US wurde in dieser Phase nie dargeboten. Vor und nach der Konditionierung wurden die Probanden sowohl bez{\"u}glich der Valenz (bzw. Unangenehmheit und Angenehmheit) als auch der Erregung (bzw. Ruhe und Aufregung) hinsichtlich der geometrischen Figuren befragt. In der ersten Studie wurde der Schreckreflex (Startle Reflex) als Maß f{\"u}r die implizite Valenz der Stimuli gemessen. Der Schreckreflex ist eine defensive Urreaktion, die aus einem Muskelzucken des Gesichts und des K{\"o}rpers besteht. Dieser Reflex ist durch pl{\"o}tzliche und intensive visuelle, taktile oder akustische Reize evoziert. Einerseits war die Amplitude des Startles bei der Anwesenheit des vorw{\"a}rts CS+ potenziert und das deutet daraufhin, dass der CS+ eine implizite negative Valenz nach der Vorw{\"a}rtskonditionierung erworben hat. Anderseits war die Amplitude des Startles bei der Anwesenheit des r{\"u}ckw{\"a}rts CS+ abgeschw{\"a}cht, was darauf hin deutet, dass der CS+ nach der R{\"u}ckw{\"a}rtskonditionierung eine implizite positive Valenz erworben hat. In der zweiten Studie wurde die oxygenierte Bloodsresponse (BOLD) mit funktioneller Magnetresonanztomographie (fMRI) erhoben, um neuronale Korrelate des Event-Timings zu erfassen. Eine st{\"a}rkere Aktivierung wurde in der Amygdala in Erwiderung auf den vorw{\"a}rts CS+ und im Striatum in Erwiderung auf den r{\"u}ckw{\"a}rts CS+ gefunden. Zum Einen entspricht dies einer Aktivierung des Defensive Motivational Systems, da die Amygdala eine wichtige Rolle beim Angstexpression und Angstakquisition hat. Deshalb wurde der vorw{\"a}rts CS+ als aversiv betrachtet. Zum Anderen entspricht dies einer Aktivierung des Appetitive Motivational System, da das Striatum eine wichtige Rolle bei Belohnung hat. Deshalb wurde der r{\"u}ckw{\"a}rts CS+ als appetitiv betrachtet. In der dritten Studie wurden Aufmerksamkeitsprozesse beim Event-Timing n{\"a}her beleuchtet, indem steady-state visuelle evozierte Potentiale (ssVEP) gemessen wurden. Sowohl der vorw{\"a}rts CS+ als auch der r{\"u}ckw{\"a}rts CS+ zog Aufmerksamkeit auf sich. Dennoch war die Amplitude der ssVEP großer w{\"a}hrend der letzen Sekunden des vorw{\"a}rts CS+, d.h. direkt vor dem aversiven US. Die Amplitude der ssVEP war aber gr{\"o}ßer w{\"a}hrend der ersten Sekunden des r{\"u}ckw{\"a}rts CS+, d.h. kurz nach dem aversiven US. Vermutlich wird die Aufmerksamkeit auf den hinsichtlich des aversiven US informativsten Teil des CS+. Alle Probanden der drei Studien haben den vorw{\"a}rts CS+ und den r{\"u}ckw{\"a}rts CS+ negativer und erregender als den Kontrollstimulus beurteilt. Daher werden die expliziten Ratings vom Event-Timing nicht beeinflusst. Bemerkenswert ist die Dissoziation zwischen den subjektiven Ratings und den physiologischen Reaktionen. Nach der Dual-Prozess Theorie werden die Verhaltensreaktionen des Menschen von zwei Systemen determiniert: einem impulsiv impliziten System, das auf assoziativen Prinzipien beruht, und einem reflektiv expliziten System, das auf der Kenntnis {\"u}ber Fakten und Werte basiert. Wichtig ist, dass die zwei Systeme auf synergetische oder antagonistische Weise agieren k{\"o}nnen. Folglich k{\"o}nnte es sein, dass das impulsive und das reflektive System nach der R{\"u}ckw{\"a}rtskonditionierung antagonistisch arbeiten. Zusammen deuten die vorliegenden Studien daraufhin, dass Event-Timing eine Bestrafung in eine Belohnung umwandeln kann, aber die Probanden erleben den Stimulus assoziiert mit einem aversiven Event als negativ. Diese Dissoziation k{\"o}nnte zum Verst{\"a}ndnis der psychiatrischen St{\"o}rungen wie z.B. Angstst{\"o}rungen oder Drogenabh{\"a}ngigkeit beitragen.},

  abstract  = {The thesis deals with the question which motivation direction—approach or avoidance—is connected to the emotion relief—a positive, low-arousal emotion, which is caused by an expected or nonexpected, motive-consistent change for the better, thus caused by the absence of an aversive stimulus. Based on the idea of postulating different levels of approach avoidance motivation, the Reflective-Impulsive Model of Behavior (RIM, Strack \& Deutsch, 2004) is applied to relief and approach avoidance. The RIM differentiates between an impulsive and a reflective system of information processing, with both systems working in relative independence from each other. Two central variables moderate the relation between relief and approach avoidance. The first is the psychological system in which approach avoidance is processed and assessed. Two levels of approach avoidance are distinguished: an impulsive distance orientation (distance change in relation to specific stimuli) and a reflective goal orientation (attainment of positive versus avoidance of negative end states). The second is the psychological system in which relief developed: In the impulsive system, relief develops as the affect that is conditioned to the absence of negative states; in the reflective system, relief develops as a result of goal-oriented behaviour of controlling or preventing of negative stimulation. The thesis looks at both moderators (level of approach avoidance and psychological system of development of relief) at once. The central prediction for the impulsive distance orientation is: Relief leads to an approach distance orientation (distance reduction), independent from the system in which relief develops. The central prediction for the reflective goal orientation is: Relief leads to an avoidance goal orientation (control of negative end states). This latter prediction is only made for the case when relief was caused by (develops in) the reflective system, that is by one's own, goal-directed behaviour; it is further necessary for an avoidance goal orientation that the relief state cannot certainly reached, instead there always has to uncertainty in the control of negative states. The methodology in the thesis is based on studies of aversive conditioning. In most studies, a differentiation paradigm is applied. The impulsive relief is operationalized via a classically conditioned relief (aversive CS-), whereas the reflective relief is operationalized via an active avoidance paradigm which ensures the methodological comparability of "reflective relief" to "impulsive relief". The predictions are as follows: Prediction A: Relief will elicit positive affective valence and an approach distance orientation. This should be true for both relief that is caused by the impulsive system and for relief that is caused by the reflective system (Experiments 2-3). Prediction B: More positive valence of relief—caused by a larger change of affective states—will elicit a stronger approach distance orientation (Experiment 4). Prediction C: Relief caused by the impulsive system will not elicit a specific goal orientation (Experiment 5). Prediction D: Uncertain self-induced relief—caused by the reflective system—will elicit an avoidance goal orientation (Experiments 6-7). In addition, Experiment 1 validated the conditioning paradigm used for the elicitation of relief. The experiments in the thesis support all predictions made in the theoretical part. The work has implications for the assumptions made in the RIM (Strack \& Deutsch, 2004). In the impulsive system, the affective valence determines approach avoidance orientation (e.g., R. Neumann \& Strack, 2000), the reflective goal not playing an important role. Relief elicits an approach orientation in the impulsive system. In the reflective system, the active goal is decisive for the approach avoidance orientation. Uncertain self-caused relief elicits an avoidance goal orientation in the reflective system. The studies of the thesis thus support and validate the assumptions made in the RIM (Strack \& Deutsch, 2004) in the specific field of motivational direction.},

In intuitions of hidden semantic coherence, people can intuitively detect whether a word triad has a common remote associate (coherent) or not (incoherent) before, and independently from actually retrieving the common associate. The present fluency-affect intuition model (FAIM) maintains that semantic coherence increases the processing fluency for coherent compared to incoherent triads, and that this increased fluency triggers brief and subtle positive affect, which is the experiential basis of these intuitions. Published work concerning 25 experiments is reviewed that gathered empirical support for this model. Furthermore, the impact of fluency and affect was also generalized to intuitions of visual coherence, and intuitions of grammaticality in an artificial grammar learning paradigm.},

  abstract  = {Humans and other animals share choice preference for smaller-but-sooner over later-but-larger rewards, indicating that the subjective value of a reward is discounted as a function of time. This phenomenon referred to as delay discounting (DD), represents one facet of impulsivity which is inherently connected with reward processing and, within a certain range, adaptive. Maladaptive levels, however, can lead to suboptimal decision-making and represent important characteristics of psychopathologies such as attention-deficit/hyperactivity disorder (ADHD). In line with a proposed influence of dysregulated dopamine (DA) levels on impulsivity, neural structures involved in DD (the ventral-striatum [VS]; orbitofrontal cortex [OFC]) are highly innervated by dopaminergic neurons. However, studies explicitly testing the triadic interplay of dopaminergic neurotransmission, impulsivity and brain activation during intertemporal choice are missing. Therefore, the first study of the thesis examined the effect of different DA-bioavailability levels, indicated by a genetic polymorphism (Val158Met) in the gene of the catechol-O-methyltransferase, on the association of delay discounting and OFC activation. OFC response to monetary rewards that varied by delay-to-delivery was recorded with functional near-infrared spectroscopy (fNIRS) in a sample of 49 healthy human subjects. The results suggest a DA-related enhancement in OFC function from low (low DA level) to partial (intermediate DA level) and full (high DA level) reward delay sensitivity. Furthermore, DA-bioavailability was shown to moderate the association of neural reward delay sensitivity and impulsivity: OFC reward delay sensitivity was strongly correlated with impulsivity at intermediate DA-levels, but not at low or high DA-levels where impulsivity was related to delay-independent OFC amplitudes. It is concluded that DA-level should be considered as a crucial factor whenever impulsivity-related brain activation, in particular to reward delay, is examined in healthy subjects. Dysfunctional reward processing, accompanied by a limited ability to tolerate reward delays (delay aversion), has been proposed as an important feature in ADHD putatively caused by striatal hypo-dopaminergia. Therefore, the aim of the second study of this thesis was to examine subcortical processing of reward delays and to test for neural indicators of a negative emotional response to delay periods. Using functional magnetic resonance imaging (fMRI), brain activation in adult patients with ADHD (n=14) and healthy control subjects (n=12) was recorded during the processing of immediate and delayed rewards. Compared with healthy control subjects, hyporesponsiveness of the VS reward system was evident in patients with ADHD for both immediate and delayed rewards. In contrast, delayed rewards evoked hyperactivation in the dorsal caudate nucleus and the amygdala of ADHD patients, corroborating the central predictions of the delay aversion hypothesis. In combination both studies support the conception of a close link between delay discounting, brain activation and dopaminergic neurotransmission. The results implicate that studies on neural correlates of DD have to account for the DA-bioavailability level and for a negative emotional response to reward delays.},

  abstract  = {The human motor system is adaptive in two senses. It adapts to the properties of the body to enable effective control. It also adapts to different situational requirements and constraints. This thesis proposes a new neural network model of both kinds of adaptivity for the motor cortical control of human reaching movements, called SURE_REACH (sensorimotor unsupervised learning redundancy resolving control architecture). In this neural network approach, the kinematic and sensorimotor redundancy of a three-joint planar arm is encoded in task-independent internal models by an unsupervised learning scheme. Before a movement is executed, the neural networks prepare a movement plan from the task-independent internal models, which flexibly incorporates external, task-specific constraints. The movement plan is then implemented by proprioceptive or visual closed-loop control. This structure enables SURE_REACH to reach hand targets while incorporating task-specific contraints, for example adhering to kinematic constraints, anticipating the demands of subsequent movements, avoiding obstacles, or reducing the motion of impaired joints. Besides this functionality, the model accounts for temporal aspects of human reaching movements or for data from priming experiments. Additionally, the neural network structure reflects properties of motor cortical networks like interdependent population encoded body space representations, recurrent connectivity, or associative learning schemes. This thesis introduces and describes the new model, relates it to current computational models, evaluates its functionality, relates it to human behavior and neurophysiology, and finally discusses potential extensions as well as the validity of the model. In conclusion, the proposed model grounds highly flexible task-dependent behavior in a neural network framework and unsupervised sensorimotor learning.},

  abstract  = {The personality construct of psychopathy is subject of growing research, but data on psychopathy in female incarcerated and in non-institutionalized samples are rare. In this thesis emotional detachment as one factor of psychopathy is investigated in general population, in patients and in incarcerated samples. After verifying the validity of the Psychopathy Personality Inventory Revised (PPI-R) measuring emotional detachment, the sensitivity of the questionnaire concerning emotional detachment has been proven. Additionally it has been shown that symptoms of attention deficit and hyperactivity disorder can be distinguished from psychopathic traits by emotional detachment. In addition, these results confirm the core role of the feature emotional detachment for psychopathy. Furthermore, two emotion recognition tasks have been conducted in a criminal female inpatients sample. Compared to the low psychopathic patients, the high psychopathic patients showed deficits in categorization only in shortly presented sad facial expressions, but rated emotional facial expressions as less arousing. These results point to emotional detachment as a core characteristic of psychopathy, and is specific even in non-incarcerated and female incarcerated samples. It can be measured with the PPI-R as well as with emotion detection tasks.},

  abstract  = {The main goals of the present thesis were to investigate how food deprivation influences food related disgust and to identify mental mechanisms that might underlie alterations in food related disgust. For this purpose, 9 studies were conducted that employed direct and indirect measures of attitudes, biological measures of affect as well as measures of real eating behavior and food choice, and compared responses of deprived and non deprived subjects on each of these measures. Spontaneous facial reactions were assessed via EMG and revealed that food deprived subjects showed weaker disgust reactions than satiated participants when being confronted with photographs of disgusting foods. Interestingly, deprived and non deprived subjects evaluated disgusting foods equally negative on a conscious level of information processing, indicating that food deprivation has the potential to attenuate food related disgust irrespective of conscious evaluations. Furthermore, it was found that food deprived participants readily consumed disgust related foods ("genetically modified foods"), while satiated participants rejected those foods. Again, no difference emerged between deprived and non deprived subjects in respect to their conscious evaluations of genetically modified foods (that were negative in both experimental groups). The dissociation between conscious evaluations and actual eating behavior that was observed amongst food deprived participants resembles the dissociation between conscious evaluations and facial reactions, thereby corroborating the assumption that alterations in food related disgust might directly influence eating behavior without changing conscious evaluations of foods. The assumption that a shift in automatic attitudes towards disgusting foods might be responsible for these effects received only partial support. That is, there was only a non significant tendency for food deprived subjects to evaluate disgusting foods more positive than satiated subjects on an automatic level of information processing. Instead, the results of the present thesis suggest that food deprived subjects exhibit a stronger motivation than satiated subjects to approach disgusting foods immediately. More precisely, food deprived participants exhibited strong approach motivational tendencies towards both, palatable and disgusting foods in an "Approach- Avoidance Task" whereas satiated participants only approached palatable (but not disgusting) foods on an automatic level of information processing. Moreover, food deprivation seems to change the subjective weighting of hedonic and functional food attributes in the context of more elaborated decisions about which foods to pick for consumption and which foods to reject. It was found that individual taste preferences were of minor importance for food deprived subjects but very important for satiated subjects when actually choosing between several food alternatives. In contrast, functional food attributes (e.g., immediate availability of a given food, large portion size) were more important selection criteria for food deprived subjects than for satiated subjects. Thus, food deprived participants were less picky than satiated participants, but showed a clear preference for those food alternatives that were functional in ending a state of food deprivation quickly - even if this meant choosing a food that was not considered tasty. Taken together, the present thesis shows that physiological need states (e.g., food deprivation) are tightly linked to the affective and motivational processing of need relevant cues. This link is so strong that food deprivation even modulates affective and motivational reactions as well as eating behavior and choice behavior towards disgusting (but need relevant) foods.},

  abstract  = {Cognitive views of the psychopathology of anxiety propose that attentional biases toward threatening information play a substantial role in the disorders' etiology and maintenance. For healthy subjects, converging evidence show that threatening stimuli attract attention and lead to enhanced activation in visual processing areas. It is assumed that this preferential processing of threat occurs at a preattentive level and is followed by fast attentional engagement. High-anxious individuals show augmented tendencies to selectively attend toward fear-relevant cues (Mathews, 1990) and exhibit elevated neural processing of threatening cues compared to non-anxious individuals (Dilger et al., 2003). Regarding attentional biases in high-anxious subjects, it remains unanswered up to now whether initial engagement of attention toward threat or difficulties to disengage from threat is an underlying mechanism. Furthermore, little is known whether the preferential (attentive) processing of threatening cues does influence perceptional outcomes of anxious subjects. In order to directly study separate components of attentional bias the first study of this dissertation was a combined reaction time and eye-tracking experiment. Twenty one spider phobic patients and 21 control participants were instructed to search for a neutral target while ignoring task-irrelevant abrupt-onset distractor circles which contained either a small picture of a spider (phobic), a flower (non-phobic, but similar to spiders in shape), a mushroom (non-phobic, and not similar to spiders in shape), or small circles with no picture. As expected, patients' reaction times to targets were longer on trials with spider distractors. However, analyses of eye movements revealed that this was not due to attentional capture by spider distractors; patients more often fixated on all distractors with pictures. Instead, reaction times were delayed by longer fixation durations on spider distractors. This result does not support automatic capture of attention by phobic cues but suggests that phobic patients fail to disengage attention from spiders. To assess whether preferential processing of phobic cues differentially affects visual perception in phobic patients compared to healthy controls, the second study of this dissertation used a binocular rivalry paradigm, where two incompatible pictures were presented to each eye. These pictures cannot be merged to a meaningful percept and temporarily, one picture predominates in conscious perception whereas the other is suppressed. 23 spider phobic patients and 20 non-anxious control participants were shown standardized pictures of spiders or flowers, each paired with a neutral pattern under conditions of binocular rivalry. Their task was to continuously indicate the predominant percept by key presses. Analyses show that spider phobic patients perceived the spider picture more often and longer as dominant compared to non-anxious control participants. Thus, predominance of phobic cues in binocular rivalry provides evidence that preferential processing of fear-relevant cues in the visual system actually leads to superior perception. In combination both studies support the notion that phobic patients process phobic cues preferentially within the visual system resulting in enhanced attention and perception. At early stages of visual processing, this is mainly reflected by delayed attentional disengagement and across time, preferential processing leads to improved perception of threat cues.},

  abstract  = {Frustration has been investigated since the early beginnings of psychological research. Yet, it is still unclear how frustration influences the two main parameters of motivation, i.e., orientation (approach-avoidance) and intensity. Some theories propose that controllable frustration increases approach motivation, thereby maintaining motivational intensity. In contrast, other theories propose that the perception of obstacles immediately elicits an avoidance orientation because of the negative valence of the perceptual input. Yet, the latter theories can not explain how motivational intensity is maintained upon encountering obstacles. The aim of the present thesis is to integrate previous contradicting assumptions by describing the influence of frustration on motivational orientation and motivational intensity on the basis of a two-system model of behavior. The definition of frustration as an unexpected obstacle blocking the attainment of an anticipated gratification implies that the obstacle is immediately perceived, whereas the goal is only represented in working memory. According to two-system models, these two types of representations influence different levels of behavior regulation. Whereas spontaneous approach-avoidance tendencies are mainly determined by the valence of the perceptual input, decisions to engage effort to reach the goal are based on knowledge about goals and appraisals of controllability of obstacles. Supporting this theorizing, six experiments demonstrated that frustration immediately activates avoidance tendencies. This was true for frustration of approach goals as well as for frustration of avoidance goals. Furthermore, this effect did not depend on the type of frustration feedback, and was found when approach-avoidance tendencies were measured after completion of goal pursuit as well as while overcoming frustration. In addition, approaching obstacles impaired performance in a subsequent task, suggesting that approaching obstacles consumed cognitive resources. This further supports the assumption that obstacles immediately activate avoidance tendencies. Furthermore, dispositional action-state orientation, which has been previously shown to moderate automatic affective reactions, influenced approach-avoidance tendencies, indicating that affect mediates the impact of frustration on behavioral tendencies. Finally, manipulations of controllability of frustration did not influence spontaneous approach-avoidance tendencies, but measures of motivational intensity such as decisions to engage more effort as well as activation of goal-relevant behavioral schemata. In sum, these findings support the assumptions that immediately elicited motivational orientations are mainly a function of the valence of perceptual input, whereas behavior to reach the goal (i.e. motivational intensity) is regulated by working memory representations such as appraisals of goal expectancy. Motivational orientations may serve to prepare organisms for quick reactions to sudden, unexpected occurrences, whereas behavior regulation based on goal appraisals may provide stability and flexibility in long-term goal pursuit.},

  abstract  = {This article describes a 2-systems model that explains social behavior as a joint function of reflective and impulsive processes. In particular, it is assumed that social behavior is controlled by 2 interacting systems that follow different operating principles. The reflective system generates behavioral decisions that are based on knowledge about facts and values, whereas the impulsive system elicits behavior through associative links and motivational orientations. The proposed model describes how the 2 systems interact at various stages of processing, and how their outputs may determine behavior in a synergistic or antagonistic fashion. It extends previous models by integrating motivational components that allow more precise predictions of behavior. The implications of this reflective-impulsive model are applied to various phenomena from social psychology and beyond. Extending previous dual-process accounts, this model is not limited to specific domains of mental functioning and attempts to integrate cognitive, motivational, and behavioral mechanisms.},

  abstract  = {One primary source for self-knowledge is social comparison. Often objective criteria for self-evaluations are not available or useful and therefore comparisons with other people play a crucial role in self-evaluations. But the question is whether social comparisons could indeed provide information about the self without consuming too much cognitive resources or time. Therefore, in this research I wanted to look at practice effects in social comparison and the particular significance of routine standards. Whereas traditional research on standard selection mostly focused on goal-oriented and strategic standard selection processes, this research sets out to integrate social cognitive knowledge, ideas, and methods. Researchers from many different fields agree that people's behavior and thinking is not fully determined by rational choices or normative considerations. Quite the contrary, factors like knowledge accessibility, habits, procedural practice, stereotyping, categorization, and many more cognitive processes play an important role. The same may be true in social comparison and standard selection. In my research I demonstrate that efficiency concerns play an important role in social comparison. Since people may not be able to engage in a strategic standard selection whenever they engage in social comparison processes, there has to be a more efficient alternative. Using routine standards would be such an alternative. The efficiency advantage of routine standards may thereby be founded not only in the abandonment of a strategic but arduous standard selection process, but also in a higher efficiency of the comparison process itself. I therefore set out to show how the use of routine standards facilitates the social comparison processes. This was done in three steps. First, I replicated and improved our former research (Mussweiler \& R{\"u}ter, 2003, JPSP) indicating that people really do use their best friends as routine standards to evaluate themselves. Second, I demonstrated that it is more efficient to compare with a routine standard than with another standard. In Studies 2 and 3 I therefore show that comparisons between the self and a routine standard (either a natural routine standard like the best friend or a experimentally induced routine standard based on practice) are faster and more efficient than comparisons with other standards. Finally, I looked at the underlying mechanism of the efficiency advantage of routine standards. The results of Studies 4 and 5 point out, that both general as well as specific practice effects occur with repeated comparisons. Whereas a specific practice effect implies the repeated processing of the same content (i.e., knowledge about the routine standard), general practice effects indicate that the pure process (i.e., comparing the self with a routine standard) becomes more efficient regardless whether new content (i.e., comparison relevant knowledge) has to be processed. Taken together, the efficiency advantage of routine standards during self-evaluation is based not only on the lack of necessity for an arduous standard selection, but is additionally supported by the facilitation of the comparison process itself. The efficiency of routine standards may provide an explanation as to why people base self-evaluations on comparisons with these standards and dispense with strategic considerations to select the most suitable standard.},

All children received categorized items of moderate typicality for Phases 1, 3, and 4. For Phase 2, children were assigned to either a training or control group, with half of the children in each group receiving category typical items and the others category atypical items. Levels of recall, sorting, and clustering were greater in Phase 2 for high-IQ children, for the typical lists, and for trained children. Both the high- and low-IQ children trained with typical items continued to show high levels of recall on the near extension phase. No group of subjects maintained high levels of recall after 1 week, although levels of sorting and/or clustering on the extension trials remained high for all groups of subjects except the low-IQ control children. This latter pattern (elevated sorting/clustering with low levels of recall) is an indication of a utilization deficiency, a phase in strategy development when children use a strategy but gain little or no benefit n performance. The results provide evidence for IQ, training, and material effects in the demonstration of a utilization deficiency.},

The results demonstrate that the knowledge base plays an important role in children's memory, but that domain knowledge cannot fully eliminate the effects of IQ on sort-recall tasks using domain-related materials. That is, although rich domain knowledge seemed to compensate for low aptitude, in that low-aptitude experts performed at the level of high-aptitude novices, its effects were not strong enough to eliminate performance differences between highand low-aptitude soccer experts.},

A second goal was to assess the effects of the training program on strategy awareness. Twenty-eight kindergarten children were pretested on two sort-recall tasks and their awareness of the use of the clustering strategy was assessed through a protocol type procedure. Half the children received seven half-hour sessions of individual training in the clustering strategy and half the children participated in a control group. Both groups were post-tested on two sort-recall tasks 2 weeks following training and again 8 weeks following training. Strategy awareness, as measured by verbal protocol, was assessed at both post-test points. The elaborate strategy training program was successful in inducing short- and long-term strategy maintenance of the clustering strategy. Trained children's clustering during sorting and clustering during recall was consistently related to the amount of items correctly recalled. No differences in strategy awareness were found. These findings demonstrate that the elaborate training procedure used in this study can be a very effective memory technique for young kindergarten children.},

We conducted this study to determine if those differences are due to systematic differences in the strategy instruction and attributional beliefs of German and U.S. teachers, and to explore metacognitive instructional practices in the two countries. Teachers responded to a questionnaire that inquired about their use of strategy instructions, fostering of reflective thinking in pupils, sources of children's learning problems, and modeling of metacognitive skills such as monitoring. The second part of the questionnaire asked about the reasons underlying children's academic successes and failures. German teachers reported more instruction of task-specific strategies, while American teachers showed more effort-related attributions. The types of strategies instructed and types of learning problems most frequently described varied across the two countries, and also according to how many years the teachers had taught. Results were discussed regarding their implications for metacognitive developmental theory, particularly regarding culture and other environmental influences on the development of controlled processing.},

Very few 4-year-olds, half the 5-year-olds, and almost all 6-year-olds appropriately chose semantically highly vs. weakly associated hiding places to make the targets easy vs. difficult to find. The second experiment showed that 4-year-olds did not strategically manipulate cues as sources of information, although they themselves proficiently used them as such in a search task. These findings are discussed with regard to research on children's developing understanding of origins of knowledge and belief and with regard to recent claims that young preschoolers possess a metacognitive understanding of cognitive cuing.},

  abstract  = {This article gives an overview of possibilities for the assessment offacial behavior. With regard to validity, results from a longitudinal study of 36 depressed patients and nine controls as weil as often schizophrenic patients and their relatives will be referred to. These results are used to illustrate the following principles which have to be taken into account when studying facial behavior: a) communication strongly facilitates facial expression, b) activation of facial behavior follows the "principle of least effort", and c) the principle of individual specificity applies to the association of nonverbal behavior and mood states. Making allowance for these principles has, among others, consequences a) for situations or conditions under which to asses behavior (specifically conditions of communication), b) for data analysis (e.g., dealing with frequent and rare events), and c) for empirical or experimental strategies (e.g., aggregation of single-case longitudinal comparisons). From the results on facial behavior during depression it can be concluded that the nonverbal reaction tendencies of endogenous and neurotic depressed patients differ. Moreover, the differential behavioral pattems observed cast doubt on the assumption of a homogeneity of affects in depression. Taking into account the conditions which govern it, facial behavior has proved to be a valid and, especially, a differential indicator for pathoIogic affective states and their changes. Given the fact that a psychiatric illness generally incorporates emotional problems it is more than surprising that little attention has been paid to the systematic study of emotional behavior. Some of the reasons for this will be clarified in the following.},

All children were tested on the maintenance and far-transfer of the strategy and task-related metamemory 1 week following training.

German children were more strategic than American children. Instructed children performed better than control children. German parents reported more instruction of strategies in the home.

The second study showed the stability of the speech patterns for different interaction themes even if dyads changed. These apparently contradictory results are reconciled by introducing the concept of "adaptive stability".

However, 6-year-olds showed higher levels of recall than 4-year-olds in both instructional conditions. Category cues were much more effective than color cues, regardless of age. In addition, clustering scores indicated that conceptual organization at both encoding and retrieval increased with age and with instruction. These results show that from 4 to 6 years of age children are learning to spontaneously employ memory strategies. In addition, they highlight the increasing importance of conceptual organization to retention of young children. Finally, the metamemory data suggest that there may be a lag between children's articulated declarative knowledge about the usefulness of conceptual organization and their procedural use of it.},

Two experiments are reported in which pre- and posttest (after the experiment) scores were measured. The pre-post-differences showed themselves to be affected by the medication. It is argued that in psychopharmacological experimentation an additional step must be included. All non-treatment factors must be examined for their stability in the course of the experiment. If they are stable, usual evaluation may take place. If changes are attributable to the treatment, personality scores must be regarded as dependent variables. They have to be evaluated together with the other observables with a multivariate model.

In Study 1, the ability to integrate the probabilities and the payoffs of simple bets was examined using the rating scale methodology. Children's choices among three of those simple bets were recorded also. By cross-classifying the children's choice and rating behavior it was shown that a three-stage developmental hypothesis of decision making is not sufficient. A four-stage hypothesis is proposed. In Study 2, the influence of enlarging the presented number of alternatives from two to three and the influence of the similarity of the alternatives on children's choice probabilities was examined with those bets. Children's choice behavior was probabilistic and was influenced only by enlarging the presented number of alternatives. These results suggest that a Bayesian approach, based on two probabilistic choice models, should not be applied in order to analyze children's choice behavior. The functional measurement approach is, as was demonstrated in Study 1, a powerful implement to further the understanding of the development of decision making.},

  abstract  = {In this work, we evaluate the status of both theory and empirical evidence in the field of experimental rest-break research based on a framework that combines mental-chronometry and psychometric-measurement theory. To this end, we (1) provide a taxonomy of rest breaks according to which empirical studies can be classified (e.g., by differentiating between long, short, and micro-rest breaks based on context and temporal properties). Then, we (2) evaluate the theorizing in both the basic and applied fields of research and explain how popular concepts (e.g., ego depletion model, opportunity cost theory, attention restoration theory, action readiness, etc.) relate to each other in contemporary theoretical debates. Here, we highlight differences between all these models in the light of two symbolic categories, termed the resource-based and satiation-based model, including aspects related to the dynamics and the control (strategic or non-strategic) mechanisms at work. Based on a critical assessment of existing methodological and theoretical approaches, we finally (3) provide a set of guidelines for both theory building and future empirical approaches to the experimental study of rest breaks. We conclude that a psychometrically advanced and theoretically focused research of rest and recovery has the potential to finally provide a sound scientific basis to eventually mitigate the adverse effects of ever increasing task demands on performance and well-being in a multitasking world at work and leisure.},

  abstract  = {For the current study the Lazarian stress-coping theory and the appendant model of psychosocial adjustment to chronic illness and disabilities (Pakenham, 1999) has shaped the foundation for identifying determinants of adjustment to ALS. We aimed to investigate the evolution of psychosocial adjustment to ALS and to determine its long-term predictors. A longitudinal study design with four measurement time points was therefore, used to assess patients' quality of life, depression, and stress-coping model related aspects, such as illness characteristics, social support, cognitive appraisals, and coping strategies during a period of 2 years. Regression analyses revealed that 55\% of the variance of severity of depressive symptoms and 47\% of the variance in quality of life at T2 was accounted for by all the T1 predictor variables taken together. On the level of individual contributions, protective buffering, and appraisal of own coping potential accounted for a significant percentage in the variance in severity of depressive symptoms, whereas problem management coping strategies explained variance in quality of life scores. Illness characteristics at T2 did not explain any variance of both adjustment outcomes. Overall, the pattern of the longitudinal results indicated stable depressive symptoms and quality of life indices reflecting a successful adjustment to the disease across four measurement time points during a period of about two years. Empirical evidence is provided for the predictive value of social support, cognitive appraisals, and coping strategies, but not illness parameters such as severity and duration for adaptation to ALS. The current study contributes to a better conceptualization of adjustment, allowing us to provide evidence-based support beyond medical and physical intervention for people with ALS.},
