The majority of researchers investigating the memory skills of retarded individuals have utilized heterogeneous samples of subjects whose sole criteria for grouping was either IQ or MA. The present experiment was designed to evaluate the short-term memory performance of subjects representing a specific type of retardation. Three groups of subjects (Down syndrome, CA control, and MA control) received a battery of tests designed to assess recall and recognition memory utilizing either auditory or visual input with verbal and nonverbal responses. Results indicated that the Down syndrome group possessed deficits in both storage and retrieval abilities, with storage of visually presented stimuli being particularly impaired.
大多数研究智力迟钝个体记忆技能的研究者使用的是异质样本，这些样本分组的唯一标准要么是智商，要么是心理年龄。本实验旨在评估代表特定类型智力迟钝的个体的短期记忆表现。三组受试者（唐氏综合征组、实足年龄对照组和心理年龄对照组）接受了一系列测试，这些测试旨在利用言语和非言语反应，通过听觉或视觉输入来评估回忆和识别记忆。结果表明，唐氏综合征组在存储和提取能力方面均存在缺陷，视觉呈现刺激的存储尤其受损。
