【摘要】 目的探讨轻度弱智儿童工作记忆能力损害的特点及其心理机制。方法采用仿制Smith的工作记忆软件,对秦巴山区部分已确诊轻度弱智儿童及正常儿童做工作记忆测验。结果两类儿童各种信息加工材料的工作记忆结果差异极显著。提示轻度弱智儿童普遍存在着工作记忆力的损害,在一般工作记忆能量与特殊工作记忆资源方面,可能也存在不同程度的损害。结论工作记忆测验可作为区分轻度弱智儿童有效的智力筛查工具。更多还原

【Abstract】 Aim To investigate the characteristics of working memory impairment in mild mental retarded(MMR) children and underlying psychological mechanism.Methods MMR cases and normal controls(NCs) were tested with modified Smith’s working memory software.Results All of the correct rates of working memory tasks in MMR cases were significantly lower than that in the NCs.Conclusion There were different degrees of specific working-memory resources impairments in MMR children,and the base of cognitive system impairment of MR children was the general capacity of working memory.Furthermore,working memory tests might be effective tools to distinguish MMR.更多还原
