摘要: 采用事件相关电位技术,以大学生为被试,运用被试间实验设计探讨反馈效价(积极反馈,消极反馈)对家族相似性类别学习的影响。研究结果表明,行为结果上相比积极反馈,消极反馈在推理测验中的成绩显著优于积极反馈。脑电结果上,P200,P300和FRN均与家族相似性类别学习中的反馈加工有关;家族相似性类别学习中,积极反馈与消极反馈存在不对称性。相比于无反馈的条件,P300对消极反馈更加的敏感,消极反馈诱发更大的波幅,而P300对于有无积极反馈并不敏感。说明消极反馈条件下,吸引学习者投入更多的注意资源进行认知加工。此外,相比无反馈条件下,消极反馈条件下FRN有更大的激活,说明了消极反馈对被试以后的行为起着更大的调节作用。总之,研究表明相比于积极反馈,消极反馈对家族相似性类别学习更加有效,错误驱动发挥较大作用。

Abstract: Using event related potential (ERPs), college students were used as participants, and the effect of feedback valence (positive feedback, negative feedback) on the family resemblance category learning was designed and tested. The results showed that, in behavioral level, participants in the negative feedback group get higher test scores than those in positive feedback group; in physiological level, that four kinds of ERPs were evoked by negative feedback and positive feedback, they were P200, P300, and FRN respectively. Feedback presented after 300~400 ms, correct the negative feedback on the reaction conditions than under conditions induce positive feedback correction P300. Feedback presented after 200-300 ms, the reaction to errors and negative feedback positive feedback under both induce production of FRN, and FRN under negative feedback was significantly greater than average volatility under positive feedback. Therefore, in studying family resemblance material, negative feedback is more effective, error-driven play a greater role.
