Abstract
Extended viewing of visual stimuli, including faces and actions, can result in adaptation causing a bias (aftereffect) in subsequently viewed stimuli. Previously, all aftereffects have been tested under highly-controlled, but unnaturalistic conditions. In this study, we investigated if adaptation to whole body actions occurred under naturalistic viewing conditions. Participants rated the weight of boxes lifted by test actors following adaptation to a different identity actor lifting a heavy box, lifting a light box, or standing still. Stimuli were presented under 3 different conditions: (1) life-sized stereoscopic presentation on a 5.3 x 2.4m screen, (2) life-sized presentation on a 5.3 x 2.4m screen without stereoscopic depth information, (3) smaller than life presentation on a 22in monitor without stereoscopic depth information. After adapting to an actor lifting heavy or light boxes, subsequently viewed boxes lifted by different actors were perceived as significantly heavier, or lighter, respectively. Aftereffects appeared to show similar dynamics as for other high-level face and action aftereffects, and were similarly sized irrespective of viewing condition. These results suggest that when viewing people in our daily lives, their actions generate visual aftereffects, and this influences our perception of the behaviour of other people.
