智障学生与正常学生再认记忆的比较研究

本研究采用中国韦氏智力量表和二项必选数字记忆测验对智障学生进行测试,二项必选数字记忆测验对正常学生进行测试,比较智障学生与正常学生及不同程度智障学生之间再认记忆的差异。结果显示1、智障学生与对照组二项测验容易条目得分的差异无统计学显著意义;困难条目得分、总分的差异有统计学显著意义;2、不同程度智障学生二项测验困难条目得分和总分的差异有统计学显著意义,容易条目得分的差异无统计学显著意义;困难条目得分智商为35-49分组显著低于智商为50-69分及70-85分组。由此得出结论智障学生的再认记忆因干扰刺激与目标刺激之间的辨别难易程度不同而存在损伤分离现象,其损伤也受到智力缺陷程度的影响。

Comparing the Recognition Memory of Students with Mental Retardation and Normal Students

Students with mental retardation were tested by Wechsler Intelligence Scale in China and Binomial Forced-Choice Digit Memory Test(BFDMT),the controls were tested by BFDMT.This comparative study tried to compare the BFDMT performances of Students with mental retardation to that of the controls,and the BFDMT performances of mental retarded students with different IQ levels.There were significant differences in the scores of difficult items and total score of BFDMT between students with mental retardation s and controls.There were ~significant differences in the difficult score and the total score among groups of students with different IQ levels.The difficult score and the total score of the students with the IQ 35-49 were significantly lower than that of the students with IQ 50-59 and with IQ 70-85.The study found that there is a dissociation in the impairment of recognition memory of students with mental retardation and the impairment is somehow effected by intellectual ~deficiency.
