认知操作背景下在线元认知调节能力的特征

利用认知任务为载体，对在线元认知调节特征进行研究，探讨了在线元认知调节的跨任务一致性和规则特异性。实验采用字母记忆与跟踪击键两种任务作为在线元认知调节的载体，通过逐步增加“提示线索”，观测个体在任务作业上的“成绩”（字母作业任务）或“成绩提高量”（跟踪击键任务），以此作为评价在线元认知调节能力的指标。结果发现，随着认知任务中潜在规律线索数量的增加，被试能够通过在线元认知调节过程提高其认知作业水平；被试通过认知任务与追述报告分别反映的在线元认知调节水平具有一致性；在线元认知调节一方面具有跨任务情境的一致性，另一方面具有规则发现的差异性。因此，基于认知操作为背景的元认知评价方法能够较好地评估在线元认知调节能力

Characteristics of On-Line Metacognitive Regulating Ability under Cognitive Context

This article presented a study of on-line metacognitive regulation in cognitive tasks,in which the characteristics of on-line cognitive regulating ability and its domain-generality were discussed.Two cognitive tasks of Letter Recall and Key Strike were used for inducing the regulating process.By increasing the"task cues"gradually,some changes were observed in the performance in Letter Recall task and performance enhancement in Key Strike task.Using them as the index of on-line metacognitive regulating ability,analysis of the result indicated that cognitive performance was enhanced through on-line metacognitive regulation as task cues increased.It was also showed that the on-line metacognitive regulating ability assessed by cognitive tasks was consistent with that came from retrospective report.The on-line metacognitive regulation was both domain-general across different tasks and domain-specific in discovering the rules.These results implied that metacognitive assessment under cognitive context could appropriately assess the on-line metacognitive regulation.
