摘　　要：采用具有不同深度信息的剪影和图片刺激为材料,要求被试完成形状判断任务,探究基于客体的一致性效应的产生机制。实验1中客体刺激呈现于屏幕中央位置;实验2进一步增强了刺激空间呈现的左右位置倾向;实验3则通过交叉手的范式分离了反应位置和反应手不同的编码对一致性效应的作用。结果发现:当刺激不存在显著的左右位置信息时,剪影刺激出现了一致性效应,图片则没有;而当刺激的空间位置信息显著时,剪影和图片均出现了一致性效应,这一效应在反应位置和反应手编码分离后仍然存在。因此得出结论:空间位置编码假说对解释基于客体的一致性效应的产生有重要作用。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. 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 placed at the center of the screen, which made the left and right position of
