How perception guides action: Figure-ground segmentation modulates integration of context features into S-R episodes.

Abstract

Perception and action are closely related. Responses are assumed to be represented in terms of their perceptual effects, allowing direct links between action and perception. In this regard, the integration of features of stimuli (S) and responses (R) into S-R bindings is a key mechanism for action control. Previous research focused on the integration of object features with response features while neglecting the context in which an object is perceived. In 3 experiments, we analyzed whether contextual features can also become integrated into S-R episodes. The data showed that a fundamental principle of visual perception, figure-ground segmentation, modulates the binding of contextual features. Only features belonging to the figure region of a context but not features forming the background were integrated with responses into S-R episodes, retrieval of which later on had an impact upon behavior. Our findings suggest that perception guides the selection of context features for integration with responses into S-R episodes. Results of our study have wide-ranging implications for an understanding of context effects in learning and behavior. (PsycINFO Database Record
