| 摘 要： | 视觉搜索不对称性是在A中搜索B完全不同于在B中搜索A.本文将采用反证法探究两个条件的目标突出于其干扰子的程度不同是否为产生该现象的原因.采用信号检测论中的有无法,当被试发现目标,按“Yes”键,否则按“No”键.变化经典实验刺激,使两个条件的目标突出于其干扰子程度相同,4个实验均发现二者目标搜索无显著性差异,产生了视觉...

| Abstract: | The visual search asymmetry is that search for stimulus A among Bs often yields completely different results from a search for B among As.This paper would explore the reason of the hypothesis by the reduction to absurdity.Its reason might be targets' salience difference between the paired searches.The signal detection theory was used.Subjects were instructed to press the Yes key as quickly as possible if they saw a target.Alternatively,they had to press the No key.Traditionally experimental stimuli were mod... |
