Title: *Perceptual Grounding of Social Cognition*
Date: Wednesday, 3 October 2018
Time: 17:00-18:30
Location: Department of Cognitive Science, CEU, Oktober 6 st. 7, room 101
Abstract:
Visual perception is attuned to detect stimuli with high social value, such
as faces, bodies and biological motion. I will argue that human visual
perception is further prepared to represent socially relevant (spatial)
relations among multiple entities. This so-far uncharted property of human
perception substantiates the construct of social vision, whereby the result
of perceptual analysis is not just shape recognition, but information ready
for inferential operations in social cognition. I will discuss the
preparedness of human visual perception to represent configurations of
multiple entities in spatial positioning that cues interaction, focusing on
three empirical phenomena. First, under conditions of low visibility, two
bodies facing each other (seemingly interacting) are recognized more
accurately and faster than two nonfacing bodies. Moreover, the recognition
of facing body-dyads is disproportionately impaired when those stimuli are
inverted. Privileged recognition and inversion effect suggest specialized
mechanisms for visual perception of interacting bodies. Second, in a visual
search task, two facing (i.e., seemingly interacting) bodies are processed
more efficiently than two nonfacing (i.e., non-interacting) bodies. In
showing that the visual search mechanism has rapid access to relations
across multiple objects, this research highlights the perceptual advantage
of facing over nonfacing dyads. Functional MRI results will further support
this observation. Third, a series of experiments based on a preferential
looking paradigm reveals discrimination of facing versus nonfacing bodies,
in 6-months-old infants. Thus, the visual sensitivity to interacting bodies
seen in adults, does not require decades of exposure to social contexts; it
could rather be a signature of early developing perceptual mechanisms that
contribute to the construction of mature social cognition. Multi-body
perception, where human observers attain a fast, initial appraisal of
possible relations in a scene, may be the crucial mechanism that channels
body perception into social cognition; in other words, the (missing) link
between perception and cognition.
We are looking forward to see you.
