相当多的研究已经测试了刺激的情感效价是否可以引导视觉搜索中的注意。使用图式情感面孔的研究经常发现相对搜索不对称（RSA），在友好人群中更有效地搜索负面面孔，反之亦然。然而，这种影响是否与情感差异或知觉特征的混淆差异有关尚不清楚。目前的研究提出并测试了RSA的一个基于相似性的账户。实验1a和1b首先复制了典型的RSA。实验2表明刺激可以在一定程度上简化而不丢失RSA。最后，实验3和4表明，RSA可以通过一个相当简单的刺激变化来逆转，而不会改变面部表情。结论是，RSA对刺激因素的强烈依赖严重质疑了情感因素驱动RSA的说法。
Quite a number of studies have tested whether the affective valence of stimuli can guide attention in visual search. Studies using schematic affective faces frequently found a relative search asymmetry (RSA), with more efficient search for a negative face in a friendly crowd than vice versa. Whether, however, this effect relates to differences in affect or to the confounded differences in perceptual features is unknown. The present study proposes and tests a similarity-based account for the RSA. Experiments 1a and 1b first replicate the typical RSA. Experiment 2 shows that the stimulus could be simplified to some degree without losing the RSA. Experiments 3 and 4, finally, demonstrate that the RSA could be reversed by a rather simple stimulus change, that leaves the facial expression intact. It is concluded that the strong dependence of the RSA on stimulus factors seriously questions the claim that emotional factors drive the RSA.
