Abstract

It has been hypothesized that learning disabled children meet short-term memory (STM) problems especially when they must bind different types of information, however the hypothesis has not been systematically tested. This study assessed visual STM for shapes and colors and the binding of shapes and colors, comparing a group of children (aged between 8 and 10 years) at risk of non-verbal learning disabilities (NLD) with a control group of children matched for general verbal abilities, age, gender, and socioeconomic level. Results revealed that groups did not differ in retention of either shapes or colors, but children at risk of NLD were poorer than controls in memory for shape-color bindings.

摘要

有一种假设认为，学习障碍儿童存在短期记忆（STM）问题，尤其是在他们必须整合不同类型信息时，但这一假设尚未得到系统验证。本研究评估了对形状和颜色的视觉STM以及形状与颜色的整合，将一组有非言语学习障碍（NLD）风险的儿童（年龄在8至10岁之间）与一组在一般语言能力、年龄、性别和社会经济水平方面相匹配的儿童对照组进行比较。结果显示，两组在形状或颜色的记忆保持方面没有差异，但有NLD风险的儿童在形状 - 颜色整合记忆方面比对照组差。
