分类在视觉搜索中的作用进行了研究，在3个颜色搜索实验中，目标是或不是线性可分离的干扰。线性可分性效应指的是在CIE颜色空间中搜索落在干扰物之间的福尔斯目标的困难（Bauer，Jolicoeur，&科万，1996 b）。观察员进行非线性可分离的搜索，其中目标落在CIE颜色空间中的两种类型的干扰。当目标和干扰物属于同一类别时，搜索就很困难。当他们属于三个不同的类别，响应时间和搜索斜率显着减少。结果表明，分类信息，当可用时，促进搜索，减少线性可分性效应。
The role of categorization in visual search was studied in 3 colour search experiments where the target was or was not linearly separable from the distractors. The linear separability effect refers to the difficulty of searching for a target that falls between the distractors in CIE colour space (Bauer, Jolicoeur, & Cowan, 1996b). Observers performed nonlinearly separable searches where the target fell between the two types of distractors in CIE colour space. When the target and distractors fell within the same category, search was difficult. When they fell within three distinct categories, response times and search slopes were significantly reduced. The results suggest that categorical information, when available, facilitates search, reducing the linear separability effect.
