学习困难小学生注意返回抑制的初探

A Preliminary Study on the Inhibition of Return in Pupils With Learning Difficulty

目的探讨学习困难小学生注意返回抑制特点。方法采用单线索条件下注意返回抑制检查范式检测,按分层整群抽样的原则将四~六年级的99名学生按学习成绩分为优秀组共计32名,中等组共计51名,学困组共计16名共三组分别进行测试。结果各组小学生SOA水平同侧反应时均长于异侧反应时(P<0.05),IOR为正值,均存在返回抑制。学困组同侧与异侧反应时均值大于中等组及优秀组。结论学困生存在返回抑制障碍,可能是导致学习障碍的影响因素之一。

Objective To study the characteristics of inhibition of return in pupils. Methods 99 pupils of 4-6 graders that can be divided into groups of a total of 32 who are excellent, and groups of a total of 51 who are mired in the middle, and groups of poor students of a total of 16 are to be taken inhibition of return test respectively. Results The groups of students SOA level on the same side of the reaction time are longer than the opposite side of the reaction time （P〈0.05）, IOR is positive, there are returned. The group of poor students on the same side and the Opposite side of the reaction when the mean are longer than medium and outstanding groups, Conclusion The obstacles of inhibition of return of poor students could be one of the influence factors of learning disabiliey.
