基于客体的一致性效应的产生机制
摘要
<p id="C2">The object-based Correspondence effect (also called object-based Simon effect), is a special spatial Correspondence effect, which refers to the phenomenon that responses are faster and more accurate when a handle of the graspable object and the response position or the responding hand are consistent than inconsistent. Tucker and Ellis (1998) first found the object-based Correspondence effect, and attributed the effect to the functional affordance of handles. In other words, when participants watch the graspable object, they automatically activate the tendency to grasp the handle of the object with their corresponding hands. Therefore, when the responding hand which is automatically activated by the handle is consistent that required by the task, responses are faster. In addition to the functional affordance, many researchers have also used the spatial position coding account to explain this effect. The account held the view that the generation of the object-based Correspondence effect was related to the position of the asymmetric handle of the stimuli, which automatically activated the response of the ipsilateral position, leading to the object-based Correspondence effect (Cho & Proctor, 2010). It's uncertain that the generation of object-based Correspondence effect is due to affordance coding or spatial coding hypothesis. <p id="C201">In the present study, three experiments were conducted to investigate the generation mechanism of the object-based Correspondence effect. The stimulus materials were the silhouettes and photographs of the frying pans. In Experiment 1 the frying pan was located at the center of the screen, participants were asked to judge the stimulus to be upright or inverted, and responded with the responding hand. The aim of it was to examine whether the silhouettes and photographs of the frying pan would exist the object-based Correspondence effect without significant spatial position. In Experiment 2, the base of the frying pan was
