Sources of information for discriminating dynamic human actions.
Despite the importance of action identification and discrimination in action perception and social cognition more broadly, little research has investigated how these processes are achieved. To this end, we sought to identify the extent to which adults capitalize on featural versus configural sources of information when discriminating small-scale human actions such as grasp and place. Results across two experiments indicate adults are sensitive to both sources of information in action discrimination, but selectively attend to featural over configural action information. The findings also parallel what is known regarding face processing: processing of configural information is especially disrupted by inversion, whereas processing of featural information is specifically affected by low-pass filtering.
