【摘要】 采用预搜索实验范式,考察当旧客体属单一范畴时,基于范畴的抑制扩散效应对预搜索的影响。结果表明:(1)字母数字的范畴差异可以指导预搜索的注意配置;(2)范畴抑制扩散效应对预展收益存在影响。当靶子与旧客体范畴不同,预展收益将受益于旧客体的范畴抑制扩散效应,当靶子与旧客体范畴相同,预展收益将受损于旧客体的范畴抑制扩散效应;(3)预搜索和全集搜索之间的范畴比率差异不是造成预展收益的原因。更多还原

【Abstract】 With the previous display of homogeneous category,the inhibitory carryover effect of category in preview search has been investigated by preview search paradigm.The results shows that:(1)the categories difference of letters and Arabian numbers can affect preview effect;(2)the inhibitory carryover effect of categories affects preview effect.The visual marking benefits from categorical carryover if the target’s category is different from prior items,but it suffers from this carryover if the target’s category is the same with the prior;(3)the different ratio between preview search and conjunction search is not the cause of the preview effect.更多还原
