我们评估了通感色彩体验(即，幻觉)是否会引导或吸引注意力。字母神经颜色联想者J和七个非联觉者搜索在背景中呈现的目标数字，这些背景与目标数字的J的颜色一致或不一致。对于J，在不一致试验上检测目标数字的搜索函数的斜率比在一致试验上检测目标数字的搜索函数的斜率浅。相比之下，对于七个非通感受试者，在一致和不一致试验中检测目标数字的搜索函数的斜率是相同的。这些发现表明，通感色彩体验通过引导或吸引注意力来影响视觉搜索的效率。(C)2003 Elsevier Inc.保留所有权利。
We evaluated whether synaesthetic colour experiences (i.e., photisms) guide or attract attention. An alphanurneric-colour synaesthete, J, and seven non-synaesthetes searched for target digits presented against backgrounds that were either congruent or incongruent with the colours of J's photisms for the target digits. For J, the slope of the search function for detecting the target digits on incongruent trials was shallower than the slope of the search function for detecting the target digits on congruent trials. In contrast, for the seven non-synaesthetes, the slopes of the search functions for detecting the target digits on congruent and incongruent trials were equivalent. These findings suggest that synaesthetic colour experiences influence the efficiency of visual search by guiding or attracting attention. (C) 2003 Elsevier Inc. All rights reserved.
