摘　　要：该文采用注意线索技术探讨颜色、角度和空间方位对视觉选择性注意的影响。研究结果表明:1)随着突现刺激呈现角度的变化,表现出从左至右的明显的倒“V”字型效应,当突现刺激特征显著时(颜色明显变化),“V”字型效应消失;2)随着SOA的延长,空间角度对选择注意加工的影响越来越显著;3)综合处理空间角度结果表明,被试对“上”方目标的反应速度最快,其次是左和右,对“下”的目标的反应速度最慢,而且相对受SOA的影响较小。The present study was intended to research the effect of spatial location, color and SOA on visual selective attention. Forty subjects were involved in this experiment. The results indicated that： （1）The factor of Spatial location have effects on the visual selective attention, with the change of the presentation angles, a significant converted ＂V＂ effect from left to right was discovered. While the targets had salient features （e.g. a salient difference of color from the distracters）, the converted ＂V＂ effects fade away. （2） With the extending of the SOA, spatial angles have more significant effects on the process of selective attention. （3） Individuals responded more quickly when the target appeared at the ＂up＂ position relative to the fixation position, then the ＂left＂ and the ＂fight＂ position, and responded slowest while the target appeared at the ＂down＂ position.
