反馈方式对家族相似性类别学习的影响

Effect of Feedback Nature on Family Resemblance Category Learning

家族相似性材料是更加接近自然的类别材料,反馈方式(正性反馈和负性反馈)对家族相似性类别学习的影响机制还需进一步研究。采用"学习-测试"范式探讨正性反馈与负性反馈对家族相似性类别学习的效率与策略的影响。研究结果表明,负性反馈组学习速度更快,并在分类任务、记忆任务上的成绩好于正性反馈组;高水平策略使用上,两组的成绩不显著。这说明在学习家族相似性材料时,负性反馈在学习结果和学习效率上均优于正性反馈。

Different nature of the feedback has a different impact on category learning. The nature of the feedback（ positive feedback and negative feedback）has what effect for the family resemblance category structure is less involved,more study is needed. In this experi- ment, Learning - test paradigm was used,learning phase used classification learning paradigm. Classification test, the single feature test, and reasoning test, three different learning depth testing tasks, were used on the testing phase. In this study, the between - subjects ex- perimental design, two feedback nature conditions （positive feedback, negative feedback）to explore the different nature of the feedback on the family resemblance category learning efficiency and learning strategies. The results show that participants learning faster on nega- tive feedback conditions of learning phase. On the test phase, negative feedback has better performance than positive feedback on single feature which needs to be test categories within single feature dimension reasoning, and the classification test tasks which was more memories recognition. The high level of strategy use, both scores were not significant. The results explain in the study of family resem- blance material on familiar and simple reasoning negative feedback more effective, error - driven play a larger role.
