We live in a world amidst complex, moving objects. Our brains constantly process dynamic visual input from walking people, driving cars, turning clocks and countless other moving objects we perceive every day, into a myriad of useful information. The aim of the present experiments is to investigate the neural mechanisms of dynamic object perception, both by considering the important category of biological motion perception, as well as more general dynamic object perception. In a first set of experiments, I investigate the selectivity of the brain areas previously correlated with biological motion perception using a new set of novel, articulating objects that appear to be animate (creatures). A second set of experiments investigates the role of ventral cortex in dynamic object perception, specifically searching for areas of cortex that showed invariance for articulatory motion that would suggest object constancy. In a final set of experiments I investigated the similarity of brain responses on the superior temporal sulcus (STS) for two sets of stimuli previously shown to elicit activity in the same subject population: point-light human actions, and Heider-Simmel type abstract social animations. Together these experiments demonstrate that ventral cortex is recruited during dynamic object perception, and increase our understanding of the neural computations occurring in STSp.
