【摘要】 采用3×2×3的混合实验设计,考察了三种线索-靶子呈现时间间隔条件下,中央线索化对动态范式中“基于客体的返回抑制”的影响。结果表明,在外周方框旋转同时或旋转停止后中央线索化时,出现了“基于客体的返回抑制”效应,但在外周方框旋转之前中央线索化时,“基于客体的返回抑制”效应却消失了。这说明中央线索化对动态范式中的“基于客体的返回抑制”有着重要的影响,也为动态范式中“基于客体的返回抑制”的空间位置抑制动态更新说提供了新的证据。更多还原

【Abstract】 The aim of the present experiment was to determine the role of the fixation cue in the object-based inhibition of return(IOR)in dynamic displays at three SOAs.When the fixation cue was presented at the same time as the peripheral squares began to move or after they stopped moving,RT was longer in the cued square than in the uncued square across three different SOAs,which was consistent with Tipper’s(1994 1999)results.No difference was found between these two conditions when the fixation cue was presented before the peripheral squares began to move.These findings revealed the importance of controlling the location of fixation cue in studies on IOR in dynamic displays and provided new evidence for the theory that object-based IOR is the result of the updating of the spatial inhibition rather than the object inhibition.更多还原
