Individuals with intellectual disability (ID) typically show weak long-term memory (LTM) skills. Understanding verbal LTM processes and searching for effective mnemonics in this population is important, to improve intervention programs. The current study aimed to assess verbal LTM abilities of adults with mild ID of mixed etiologies, and to offer a simple memorization technique based on vocal production. Participants (n = 55) learned lists of different study materials (images of familiar and unfamiliar objects, written words, and sentences) by vocal production (saying or reading aloud) or by no-production (looking, listening, or reading silently). Memory tests followed. Better memory was found for vocally produced images of familiar objects, written words, and sentences. The results show that adults with mild ID can benefit from the relative distinctiveness of items at study. Hence, vocalization may be used in educational and therapeutic contexts for this population, improving memory performance.

使用发声来改善智障成人的长期言语记忆。

智障 (ID) 个体通常表现出较弱的长期记忆 (LTM) 技能。了解语言 LTM 过程并在该人群中寻找有效的助记符对于改进干预计划很重要。目前的研究旨在评估混合病因的轻度 ID 成人的语言 LTM 能力，并提供一种基于发声的简单记忆技术。参与者 (n = 55) 通过发声（大声说或读）或不发声（看、听或默读）学习了不同学习材料的列表（熟悉和不熟悉的物体的图像、书面单词和句子）。记忆测试紧随其后。对于熟悉的物体、书面单词和句子的声音产生的图像，人们发现了更好的记忆力。结果表明，轻度 ID 的成年人可以从研究项目的相对独特性中受益。因此，发声可用于该人群的教育和治疗环境，以提高记忆力。
