Most behaviors are driven by more than one motive, yet it is unclear how different motives interact and how such motive combinations affect the neural computation of the behaviors they drive. To answer this question, we induced two prosocial motives simultaneously (multi-motive condition) and separately (single motive conditions). After the different motive inductions, participants performed the same choice task in which they allocated points in favor of the other person (prosocial choice) or in favor of themselves (egoistic choice). We used fMRI to assess prosocial choice-related brain responses and drift diffusion modeling to specify how motive combinations affect individual components of the choice process. Our results showed that the combination of the two motives in the multi-motive condition increased participants' choice biases prior to the behavior itself. On the neural level, these changes in initial prosocial bias were associated with neural responses in the bilateral dorsal striatum. In contrast, the efficiency of the prosocial decision process was comparable between the multi-motive and the single-motive conditions. These findings provide insights into the computation of prosocial choices in complex motivational states, the motivational setting that drives most human behaviors .}, language = {en} } @article{KleihDahmsBotrelKuebler2021, author = {Kleih-Dahms, Sonja Christina and Botrel, Loic and K{\"u}bler, Andrea}, title = {The influence of motivation and emotion on sensorimotor rhythm-based brain-computer interface performance}, series = {Psychophysiology}, volume = {58}, journal = {Psychophysiology}, number = {8}, doi = {10.1111/psyp.13832}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-259664}, year = {2021}, abstract = {While decades of research have investigated and technically improved brain-computer interface (BCI)-controlled applications, relatively little is known about the psychological aspects of brain-computer interfacing.

Two laboratory experiments (total N = 250) manipulated situational regulatory focus before providing opportunities for impulse buying. In addition, cognitive constraint was manipulated as a potential boundary condition for regulatory focus effects. Situational promotion focus increased impulse buying relative to situational prevention focus in participants with strong chronic promotion, consistent with regulatory fit theory and independently of cognitive constraint. Surprisingly, situational promotion focus also increased impulse buying in participants with strong chronic prevention, but only under low cognitive constraint. These results may be explained by diverging mediating cognitive processes for promotion vs. prevention focus' effect on impulse buying.

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.}, subject = {Motivation}, language = {en} } @article{Krueger1988, author = {Kr{\"u}ger, H.-P.}, title = {Psychologische Charakteristika der "D{\"u}ker-Aufgabe" oder "Was ist die Leistung an der Leistung?"}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-41460}, year = {1988}, abstract = {In den Experimenten H.

While acknowledging that these two caveats express serious concerns regarding the debate on explanatory models, I show that phenomenology has the resources to respond to them. These can be found in analyses of different types of causation relating to different regions of reality and in the structure of explanatory models based on exemplarity.

Virtual reality (VR)-based treadmill training can increase motivation and improve therapy outcomes. The present study evaluated an immersive virtual reality application (using a head-mounted display, HMD) for gait rehabilitation with patients to (1) demonstrate its feasibility and acceptance and to (2) compare its short-term effects to a semi-immersive presentation (using a monitor) and a conventional treadmill training without VR to assess the usability of both systems and estimate the effects on walking speed and motivation. Methods: In a within-subjects study design, 36 healthy participants and 14 persons with MS or stroke participated in each of the three experimental conditions (VR via HMD, VR via monitor, treadmill training without VR). Results: For both groups, the walking speed in the HMD condition was higher than in treadmill training without VR and in the monitor condition. Healthy participants reported a higher motivation after the HMD condition as compared with the other conditions. Importantly, no side effects in the sense of simulator sickness occurred and usability ratings were high. No increases in heart rate were observed following the VR conditions. Presence ratings were higher for the HMD condition compared with the monitor condition for both user groups. Most of the healthy study participants (89\%) and patients (71\%) preferred the HMD-based training among the three conditions and most patients could imagine using it more frequently. Conclusions For the first time, the present study evaluated the usability of an immersive VR system for gait rehabilitation in a direct comparison with a semi-immersive system and a conventional training without VR with healthy participants and patients. The study demonstrated the feasibility of combining a treadmill training with immersive VR. Due to its high usability and low side effects, it might be particularly suited for patients to improve training motivation and training outcome e. g. the walking speed compared with treadmill training using no or only semi-immersive VR. Immersive VR systems still require specific technical setup procedures.

In this respect, motivation could be defined as "motivation-to-help." The aim of this study was to investigate, whether subjects with high motivation for helping and who are highly empathic would perform better with a BCI controlled by event-related potentials (P300-BCI). We included N = 20 healthy young participants na{\"i}ve to BCI and grouped them according to their motivation for participating in a BCI study in a low and highly motivated group. Motivation was further manipulated with interesting or boring presentations about BCI and the possibility to help patients. Motivation for helping did neither influence BCI performance nor the P300 amplitude. Post hoc, subjects were re-grouped according to their ability for perspective taking. We found significantly higher P300 amplitudes on parietal electrodes in participants with a low ability for perspective taking and therefore, lower empathy, as compared to participants with higher empathy. The lack of an effect of motivation on BCI performance contradicts previous findings and thus, requires further investigation. We speculate that subjects with higher empathy who are good perspective takers with regards to patients in potential need of BCI, may be more emotionally involved and therefore, less able to allocate attention on the BCI task at hand.}, language = {en} } @phdthesis{Hoefling2008, author = {H{\"o}fling, Atilla}, title = {Beggars cannot be choosers - The influence of food deprivation on food related disgust}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-34609}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2008}, 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.}, subject = {Ekel}, language = {en} }
