The tell-tale body: investigating the intertwined relationship between social cognition and visual perception through physiological indices.

Dapor, Cecilia 20 February 2025 (has links)
This thesis explores the deep connection between social cognition and visual perception, focusing on how bodily cues reveal this relationship. We aim to highlight the physiological foundations of the visual and cognitive aspects of social perception, postulating a reciprocal interaction between early perceptual processes and social predispositions. Through three studies, we investigated the special status of social stimuli in perception and the link between physiological reactivity to emotional cues and social abilities. Using a breaking continuous flash suppression (b-CFS) paradigm, we manipulated visual awareness of emotional stimuli and measured breakthrough times to distinguish between conscious and subconscious processing. We tested three types of stimuli: emotional faces, emotional bodies, and threatening animals, while recording autonomic responses - skin conductance, pupil dilation, and facial EMG - both before and after conscious awareness. Social skills were assessed through self-report questionnaires. Our findings revealed distinct physiological activation patterns across stimuli. Emotional faces elicited the strongest effects, modulating all three autonomic indices both before and after conscious awareness. In contrast, body postures did not trigger significant physiological differentiation, except for pupil dilation, which increased for inverted bodies, likely reflecting cognitive load. Phobic stimuli, particularly intact images of threatening animals, heightened autonomic responses preconsciously, supporting the evolutionary significance of threat detection. Individual differences shaped these effects. Higher empathy correlated with greater preconscious pupil dilation in response to emotional faces, whereas individuals with lower social tendencies exhibited reduced pupil reactivity. For body stimuli, alexithymic traits were linked to increased facial muscle activity, suggesting heightened muscle tension in socially anxious individuals. Moreover, arachnophobia influenced early visual and physiological responses, with phobic participants displaying delayed reactions to intact spider images, likely reflecting avoidance mechanisms. Overall, our findings emphasize that perception is not a passive process but is shaped by social experiences, personality traits, and bodily states, even at a preconscious level. This supports the idea that our perceptual and physiological systems are intrinsically linked to individual differences, reinforcing the embodied and socially embedded nature of perception.

Специфика восприятия спортивной женской телесности в современной российской культуре : магистерская диссертация / Perception patterns of female athletic embodiment in contemporary Russian culture

Мозолева, И. И., Mozoleva, I. I. January 2016 (has links)
В диссертации анализируется специфика восприятия женской телесности и конструирования представлений об идеальном женском спортивном теле в современной российской культуре. Предложена авторская модель телесности, включающая эстетический, функциональный и социальный аспекты. Определены особенности восприятия разных типов женской спортивной телесности молодыми российскими мужчинами. / The dissertation explores the patterns guiding the perception of female embodiment and the construction of idealized female athletic body images in contemporary Russian culture. The author proposes an original model of embodiment combining aesthetic, functional and social aspects. The text identifies patterns governing young Russian males’ perceptions of differing types of female athletic embodiment.
