  abstract  = {The present thesis addresses cognitive processing of voice information. Based on general theoretical concepts regarding mental processes it will differentiate between modular, abstract information processing approaches to cognition and interactive, embodied ideas of mental processing. These general concepts will then be transferred to the context of processing voice-related information in the context of parallel face-related processing streams. One central issue here is whether and to what extent cognitive voice processing can occur independently, that is, encapsulated from the simultaneous processing of visual person-related information (and vice versa). In Study 1 (Huestegge \& Raettig, in press), participants are presented with audio-visual stimuli displaying faces uttering digits. Audiovisual gender congruency was manipulated: There were male and female faces, each uttering digits with either a male or female voice (all stimuli were AV- synchronized). Participants were asked to categorize the gender of either the face or the voice by pressing one of two keys in each trial. A central result was that audio-visual gender congruency affected performance: Incongruent stimuli were categorized slower and more error-prone, suggesting a strong cross-modal interaction of the underlying visual and auditory processing routes. Additionally, the effect of incongruent visual information on auditory classification was stronger than the effect of incongruent auditory information on visual categorization, suggesting visual dominance over auditory processing in the context of gender classification. A gender congruency effect was also present under high cognitive load. Study 2 (Huestegge, Raettig, \& Huestegge, in press) utilized the same (gender-congruent and -incongruent) stimuli, but different tasks for the participants, namely categorizing the spoken digits (into odd/even or smaller/larger than 5). This should effectively direct attention away from gender information, which was no longer task-relevant. Nevertheless, congruency effects were still observed in this study. This suggests a relatively automatic processing of cross-modal gender information, which eventually affects basic speech-based information processing. Study 3 (Huestegge, subm.) focused on the ability of participants to match unfamiliar voices to (either static or dynamic) faces. One result was that participants were indeed able to match voices to faces. Moreover, there was no evidence for any performance increase when dynamic (vs. mere static) faces had to be matched to concurrent voices. The results support the idea that common person-related source information affects both vocal and facial features, and implicit corresponding knowledge appears to be used by participants to successfully complete face-voice matching. Taken together, the three studies (Huestegge, subm.; Huestegge \& Raettig, in press; Huestegge et al., in press) provided information to further develop current theories of voice processing (in the context of face processing). On a general level, the results of all three studies are not in line with an abstract, modular view of cognition, but rather lend further support to interactive, embodied accounts of mental processing.},

  abstract  = {Regulatory focus (RF) theory (Higgins, 1997) states that individuals follow different strategic concerns when focusing on gains (promotion) rather than losses (prevention). Applying the Reflective-Impulsive Model (RIM, Strack \& Deutsch, 2004), this dissertation investigates RF's influence on basic information processing, specifically semantic processing (Study 1), semantic (Study 2) and affective (Study 3) associative priming, and basic reflective operations (Studies 4-7). Study 1 showed no effect of RF on pre-activation of RF-related semantic concepts in a lexical decision task (LDT). Study 2 indicated that primes fitting a promotion focus improve performance in a LDT for chronically promotion-focused individuals, but not chronically prevention-focused individuals. However, the latter performed better when targets fit their focus. Stronger affect and arousal after processing valent words fitting an RF may explain this pattern. Study 3 showed some evidence for stronger priming effects for negative primes in a bona-fide pipeline task (Fazio et al., 1995) for chronically prevention-focused participants, while also providing evidence that situational prevention focus insulates individuals from misattributing the valence of simple primes. Studies 4-7 showed that a strong chronic prevention focus leads to greater negation effects for valent primes in an Affect Misattribution Procedure (Payne et al., 2005), especially when it fits the situation. Furthermore, Study 6 showed that these effects result from stronger weighting of negated valence rather than greater ease in negation. Study 7 showed that the increased negation effect is independent of time pressure. Broad implications are discussed, including how RF effects on basic processing may explain higher-order RF effects.},

  abstract  = {To simplify a judgment, people often base it on easily accessible information. One cue that is usually readily available is processing fluency - a metacognitive feeling of ease of cognitive processing. Consequently, processing fluency is used as a cue for many different types of judgment, such as judgment of truth, confidence, and novelty. The present work describes results of three studies investigating various aspects of processing fluency effects on judgment. Processing fluency has been sometimes equated with speed of a cognitive process. Therefore, response times have been used for evaluation of processing fluency. However, response times in experimental tasks often do not encompass only the time needed for a given process, but also the time needed for a decision based on the resulting information. The study described in Chapter II uses a novel experimental method that enables separation of reading and decision times. The results show that people make a decision about liking of pseudowords faster when the pseudowords are hard-to-pronounce (i.e., disfluent) than when they are moderate in pronounceability. This suggests that response times cannot be used as a proxy for processing fluency when they include the time needed to make a decision. One of the studies of judgmental effects of processing fluency showed that food additives with easier pronounceable names are judged to be less harmful than those with hard-to-pronounce names. While people encounter food additives that are safe more often, this environmental association may be in the opposite direction for some categories of objects. For example, people are more likely to see names of especially dangerous criminals in the news. Chapter III describes a study which initially tested whether the fluency-safety association may be in the opposite direction for some categories of objects as a consequence of this selective exposure to especially dangerous exemplars. The results did not show support for this hypothesis. Furthermore, subsequent studies suggest that the previously found association between fluency and safety is replicable with the original stimuli used in the previous research, but not with newly constructed stimuli. Chapter IV describes a study which applied a finding from the processing fluency literature to a positive psychology exercise in order to increase its effectiveness. Namely, the experiment manipulated the number of good things that participants listed daily for two weeks as part of the exercise. While listing more things was considered harder, the number of things listed each day had no effect on effectiveness of the exercise.},

  abstract  = {Both specific stimulus valence and unspecific processing dynamics can influence evaluative responses. Eight experiments investigated their respective influence on evaluative judgments in the domain of stereotyping. Valence of stereotypic information and consistency-driven fluency were manipulated in an impression formation paradigm. When information about the to-be-evaluated target person was strongly valenced, no effects of consistency-driven fluency were observed. Higher cognitive processes, valence of inconsistent attributes, processing priority of category information, and impression formation instructions were ruled out as possible factors responsible for the non-occurrence of fluency effects. However, consistency-driven fluency did influence the evaluative judgment, if the information about a target person was not strongly valenced. It is therefore concluded that both stimulus valence and consistency-driven processing fluency play a role in evaluative judgments in the domain of stereotyping. The respective impact of stimulus valence is much stronger than the impact of unspecific processing dynamics, however. Implications for fluency research and the applied field of stereotype change are discussed.},

  abstract  = {Nach langer Dominanz rationaler Urteils- und Entscheidungsmodelle in der Moralpsychologie (z.B. Kohlberg, 1969) besteht seit einiger Zeit verst{\"a}rktes Interesse an intuitiven, emotionalen Einfl{\"u}ssen auf moralische Urteile und Entscheidungen (z.B. Greene, 2007; Haidt, 2001; Monin, Pizarro, \& Beer, 2007). Der Einfluss von Emotionen auf moralische Entscheidungen wird in der Literatur u.a. mittels heuristischer, non-kompensatorischer Informationsverarbeitung erkl{\"a}rt (z.B. Sinnott-Armstrong, Young, \& Cushman, 2010; Sunstein, 2005; Tobler, Kalis, \& Kalenscher, 2008). Hierbei wird jedoch der Prozess der Emotionsentstehung ignoriert. Appraisaltheorien postulieren, dass Emotionen durch die Inkoh{\"a}renz (oder Diskrepanz) von Verhaltensrepr{\"a}sentationen wie Zielen und Aktionen entstehen (Moors, 2009). Emotionsentstehung und (intuitives) Entscheiden kann in einem Modell vereint werden sobald man bei beiden Prozessen eine konnektionistische Struktur (z.B. Barnes \& Thagard, 1996) zugrunde legt. Die vorliegende Arbeit kontrastiert beide Perspektiven intuitiv-emotionalen Entscheidens im Hinblick auf Schuld und Kooperation.},

  abstract  = {Although age is one of the most salient and fundamental aspects of human faces, its processing in the brain has not yet been studied by any neuroimaging experiment. Automatic assessment of temporal changes across faces is a prerequisite to identifying persons over their life-span, and age per se is of biological and social relevance. Using a combination of evocative face morphs controlled for global optical flow and functional magnetic resonance imaging (fMRI), we segregate two areas that process changes of facial age in both hemispheres. These areas extend beyond the previously established face-sensitive network and are centered on the posterior inferior temporal sulcus (pITS) and the posterior angular gyrus (pANG), an evolutionarily new formation of the human brain. Using probabilistic tractography and by calculating spatial cross-correlations as well as creating minimum intersection maps between activation and connectivity patterns we demonstrate a hitherto unrecognized link between structure and function in the human brain on the basis of cognitive age processing. According to our results, implicit age processing involves the inferior temporal sulci and is, at the same time, closely tied to quantity decoding by the presumed neural systems devoted to magnitudes in the human parietal lobes. The ventral portion of Wernicke's largely forgotten perpendicular association fasciculus is shown not only to interconnect these two areas but to relate to their activations, i.e. to transmit age-relevant information. In particular, post-hoc age-rating competence is shown to be associated with high response levels in the left angular gyrus. Cortical activation patterns related to changes of facial age differ from those previously elicited by other fixed as well as changeable face aspects such as gender (used for comparison), ethnicity and identity as well as eye gaze or facial expressions. We argue that this may be due to the fact that individual changes of facial age occur ontogenetically, unlike the instant changes of gaze direction or expressive content in faces that can be "mirrored" and require constant cognitive monitoring to follow. Discussing the ample evidence for distinct representations of quantitative age as opposed to categorical gender varied over continuous androgyny levels, we suggest that particular face-sensitive regions interact with additional object-unselective quantification modules to obtain individual estimates of facial age.},

  abstract  = {The scope of the present work encompasses the influence of experience (i.e. expertise) for feature processing in unconscious information processing. In the introduction, I describe the subliminal priming paradigm, a method to examine how stimuli, we are not aware of, nonetheless influence our actions. The activation of semantic response categories, the impact of learned stimulus-response links, and the action triggering through programmed stimulus-response links are the main three hypotheses to explain unconscious response activation. Besides, the congruence of perceptual features can also influence subliminal priming. On the basis of the features location and form, I look at evidence that exists so far for perceptual priming. The second part of the introduction reviews the literature showing perceptual superiority of experts. This is illustrated exemplarily with three domains of expertise - playing action video games, which constitutes a general form of perceptual expertise, radiology, a more natural form of expertise, and expertise in the game of chess, which is seen as the Drosophila of psychology. In the empirical section, I report nine experiments that applied a subliminal check detection task. Experiment 1 shows subliminal response priming for chess experts but not for chess novices. Thus, chess experts are able to judge unconsciously presented chess configurations as checking or nonchecking. The results of Experiment 2 suggest that acquired perceptual chunks, and not the ability to integrate perceptual features unconsciously, was responsible for unconscious check detection, because experts' priming does not occur for simpler chess configurations which afforded an unfamiliar classification. With a more complex chess detection task, Experiment 3 indicates that chess experts are not able to process perceptual features in parallel or alternatively, that chess experts are not able to form specific expectations which are obviously necessary to elicit priming if many chess displays are applied. The aim of Experiment 4-9 was to further elaborate on unconscious processing of the single features location and form in novices. In Experiment 4 and 5, perceptual priming according the congruence of the single features location and form outperformed semantically-based response priming. Experiment 6 and 7 show that (in contrast to form priming) the observed location priming effect is rather robust and is also evident for an unexpected form or colour. In Experiment 8, location and form priming, which was additionally related to response priming, were directly compared to each other. Location priming was again stronger than form priming. Finally, Experiment 9 demonstrates that with the subliminal check detection task it is possible to induce response priming in novices when the confounding influences of location and form are absent. In the General discussion, I first summarized the findings. Second, I discuss possible underlying mechanisms of different subliminal perception in experts and novices. Third, I focus on subliminal perceptual priming in novices, especially on the impact of the features location and form. And finally, I discuss a framework, the action trigger account that integrates the different results of the present work.},
