In two experiments, the question of whether working memory could support an articulatory rehearsal loop in the visuospatial domain was investigated. Deaf subjects fluent in American Sign Language (ASL) were tested on immediate serial recall. In Experiment 1, with ASL stimuli, evidence was found for manual motoric coding (worse recall under articulatory suppression) and previous findings of ASL-based phonological coding (worse recall for phonologically similar lists) were replicated [corrected]. The two effects did not interact, suggesting separate components which both contribute to performance. Stimuli in Experiment 2 were namable pictures, which had to be recoded for ASL-based rehearsal to occur. Under these conditions, articulatory suppression eliminated the phonological similarity effect. Thus, an articulatory process seems to be used in translating pictures into a phonological code for memory maintenance. These results indicate a configuration of components similar to the phonological loop for speech, suggesting that working memory can develop a language-based rehearsal loop in the visuospatial modality.
在两项实验中，研究了工作记忆是否能够在视觉空间领域支持一个言语复述环路的问题。对精通美国手语（ASL）的聋人受试者进行了即时系列回忆测试。在实验1中，使用ASL刺激，发现了手动运动编码的证据（在言语抑制下回忆更差），并且基于ASL的语音编码的先前发现（语音相似列表的回忆更差）得到了重复[已修正]。这两种效应没有相互作用，表明有两个独立的成分都对表现有贡献。实验2中的刺激是可命名的图片，为了基于ASL的复述发生，这些图片必须重新编码。在这些条件下，言语抑制消除了语音相似性效应。因此，在将图片转换为用于记忆维持的语音代码时似乎使用了一个言语过程。这些结果表明了一种类似于言语语音环路的成分配置，表明工作记忆可以在视觉空间模态中形成一个基于语言的复述环路。
