Specifically, emotions are assumed to arise from the contents of perception. The contents of perception, on the other hand, have been conceived to be independent of any perceiver-based mental variables such as affect or mood. The implied temporal processing order of this approach makes intuitive sense, as perceiving something can be considered as a necessary prerequisite for it to evoke an emotional response. Thus, our emotional appraisal of something (e.g., fear of it) will not affect our perceptual experience of it. However, more contemporary models of mental processing allow for a bidirectional approach to understanding the interactions of affect and perception. In this dissertation, I describe a general framework of mental action called predictive processing (PP) and the specific applications of this framework to visual perception as well as to affect and mood. Based on these theoretical considerations, I will then derive a hypothesized formal relationship of the two constructs which allows for perception, and more specifically, perceptual precision weighting, to be influenced by affective variables. I continue with describing and summarizing the three dissertation studies, which have all looked at different aspects of positive and negative affect (state, trait, induced) and their relation to visual phenomena. I will end by discussing the implications of the observed effects on the debate over potential influences of affective variables on visual perception. All conducted experiments aimed at relating affective variables with parameters of visual precision weighting (PW), i.e., how much weight is ascribed to prior information and current sensory inputs, respectively. In study 1, we have shown that individuals with higher trait anxiety tend to rely stronger on a predictive cue rather than on actual sensory evidence when they were asked to judge the direction of a motion stimulus. Study 2 suggests that induced negative affect leads to less susceptibility to perceptual filling-in in the uniformity illusion (UI), indicating attenuated reliance on priors when affective state valence is negative. In study 3, we showed that affective states influenced perceptual stability in binocular rivalry. Specifically, positive baseline affect was linked to longer phase durations, suggesting a stronger influence of priors, while induced negative affect was related to a reduced stimulus specific bias, suggesting a reduced influence of priors. Importantly, all studies were conducted with affectively neutral stimuli and in samples of healthy participants. The findings are thus unlikely to stem from attentional mood congruency biases or altered stimulus processing in patient groups. In summary, these results suggest an influential role of affect in visual perception. The findings highlight specifically the role of affective state valence, showing that more negative valence was associated with less reliance on priors. The specific influence of affective traits on the other hand was found less consistently across the different studies. While we found trait anxiety to be associated with a tendency to disregard new sensory evidence and to make stronger use of priors in a motion direction detection task, this link was not found during binocular rivalry. These findings are difficult to explain invoking traditional conceptions of independent affective and perceptual processing, whereas they are largely in line with a predictive processing approach to emotion-perception interactions. In this account, changing prediction error rates are accompanied by short-term variations in affective state and function to incentivize initiation of changes in current PW parameters. However, we found only limited evidence for conceptualizing affective traits as long-term tendencies to incorporate new sensory evidence into one’s current perception. This holds important implications for different conceptions of affective states and traits, their involvement in perceptual processing, as well as for closely related topics such as the general debate about the cognitive penetrability of perception.","100 Seiten","https://refubium.fu-berlin.de/handle/fub188/39312||http://dx.doi.org/10.17169/refubium-39030","urn:nbn:de:kobv:188-refubium-39312-9","eng","http://www.fu-berlin.de/sites/refubium/rechtliches/Nutzungsbedingungen","100 Philosophie und Psychologie::150 Psychologie::152 Sinneswahrnehmung, Bewegung, Emotionen, Triebe","Affective Realism||Cognitive Penetrability||Predictive Processing||Emotion Perception Interactions","The Role of Affective Experience in Visual Perception: Insights from Predictive Processing","Dissertation","free","open access","accept","Text","Erziehungswissenschaft und Psychologie"
