Abstract:The visual system uses high-level knowledge to predict and constrain incoming sensory signals to increase the speed and efficiency of object recognition and action. Thus, we hypothesized that graspable objects would bias lower-level visual processing toward action-relevant object features (e.g., orientation) while non-graspable objects would bias toward less action-relevant features (e.g., saturation). Participants viewed images of objects that did or did not afford grasping and were located close to or far fr… Show more
