Abstract: The present study was divided into two experiments using a continuous cue-matching task paradigm to separate cue change from task switching, to examine the effect of cue matching on task switching, and to examine whether prolonged CTI had an effect on pure switching costs. The experimental results showed that in the cue-matching condition, task switching was associated with longer reaction times and lower accuracy rates than task repetition, that is, the typical switching cost; in the cue-mismatch condition, the reaction time switching cost disappeared and the accuracy rate switching cost reversed. The disappearance and reversal of the conversion cost may stem from cognitive conflicts arising from inconsistent cue and task processing results, which suggests that individuals may combine cues and tasks in cue-task switching as a whole with hierarchical correlations.

Key words: cue-matching, task switching, switching cost

摘要: 本研究分为两个实验,采用连续线索匹配任务范式将线索变化与任务转换分离,考察线索匹配对任务转换的影响,并考察延长CTI(cue-target interval)是否也对纯粹的转换代价产生影响。实验结果表明,在线索匹配情况下,任务转换比任务重复的反应时更长,正确率更低,体现了典型的转换代价;在线索不匹配条件下,反应时转换代价消失,正确率转换代价反转。CTI长短对任务转换代价的影响仅见于线索匹配条件,线索不匹配时无此效应。转换代价的消失与反转可能源于线索与任务加工结果不一致产生的认知冲突,反映了个体在线索任务转换中可能将线索与任务组合为一个具有层级关联性的整体。
