视觉注意选择性的空间位置效应的研究

Spatial Location Effect in Visual Selective Attention

采用注意线索技术探讨颜色、角度和空间位置对视觉选择性注意的影响。研究结果表明 :( 1 )目标与干扰刺激颜色相同时 ,表现出明显的注意空间位置效应 ;( 2 )目标与干扰刺激颜色不同时 ,空间位置效应明显弱化 ;( 3 )整体而言 ,注意加工速度从左到右均表现出明显的“V”字形效应。

The present study focused on whether the reaction time would be significantly different when the target was presented in different colors,angles,and spatial locations.The research method was attention cue paradigm.The results showed that:(1) When the color of target and distractor was the same,there was significant spatial location effect;(2) When the color of target and distractor was not same,the spatial location effect was decreased;(3) The result also showed “V form” attentional gradient effect and different spatial location from left to right.
