| 摘 要： | 考察等亮度条件下新旧客体之间的范畴关系对预搜索(preview search)的影响.以字母和数字为范畴材料,以搜索一个靶子字母(H)或数字(6)为任务,以预搜索为实验范式.结果表明:(1)当旧客体为数字而靶子为字母时,产生了完整的预搜索效应;(2)当旧客体为字母而靶子为数字时,只产生了部分预搜索效应.这些结果显示,在等亮度条件下,范畴信息有助于产生预搜索效应,而且存在非对称性.

| Abstract: | The effect of categorical relationship between old and new objects on preview search at isoluminance was studied.The categorical stimuli were letters and numbers.Subjects' task was to detect a target letter(H) or number(6).The experimental method was a preview search paradigm.The results showed that: a) When old objects were numbers and the target was an H,there was perfect preview effect(Experiment 1);b) When old objects were letters and the target was a 6, there was part preview effect(Experiment 2).The results suggest that categorical information can influence preview search even at isoluminance and there be an asymmetry in categorical preview effect. |
