任务类型对不同SOA条件下基于颜色重复劣势效应的影响*

采用探测任务和辨别任务,分别考察了不同线索与目标呈现时间间隔(SOA)条件下出现的基于颜色的重复劣势效应(repetition disadvantage,RD)。研究结果发现:探测任务下和辨别任务下出现基于颜色的RD效应分别倾向于解释为重复知盲现象和基于颜色的IOR效应。关于不同的任务类型对基于颜色的RD效应的影响,可以用特征个体化理论解释。实验3采用Go/No go任务,通过进一步地分析提出任务类型背后,被试对目标刺激的语义加工水平才是影响基于颜色RD效应抑制本质的关键因素。关于该因素对基于颜色重复劣势效应的影响,可以用评价窗口理论解释。

The Effect of Task Type on Color-Based Repetition Disadvantage Effect in Different SOA Conditions

With different stimulus onset asynchrony (SOA), the effects of task type on color-based repetition disadvantage (RD) effect were explored in 2 experiments. When the task type was detection task, the color-based RD effect is the repetition blindness in nature. However, when the task demand was color discrimination, the RD effect tend to be explained as the color-based inhibition of return. The results can be appropriately explained by the token individuation theory. Further analysis, the author proposes that the level of semantic processing of target stimulus is the fundamental determinants. Experiment 3 was used to Go/No go task, the results showed color-based IOR as same as experiment 2, which can be explained by the theory of “Evaluation Window Account”.
