两个非言语短期记忆任务，图片识别和配对的关联任务，由失语症和脑损伤对照组（各52）进行。对于这两个任务的答案形式上的替代品有系统地不同的3个维度，其中一个已被突出显示的目标图片之前，每一个项目的实验。在这两项任务中，失语症患者比大脑受损的对照组在那些事先受到压力的特征上犯了更多的错误;他们比对照组更不善于利用集中注意力。这些错误的数量与在令牌测试，图片命名和单词理解任务的性能。有没有组之间的差异，在语义显着性的区别功能或在语义和语音之间的关系表示的参考刺激的话的变化。缺乏互动可能是由于在这两个任务中存在强烈的天花板效应。
Two nonverbal short-term memory tasks, a picture recognition and a paired association task, were performed by matched groups of aphasics and brain-damaged controls (52 each). For both tasks the alternatives on the answer forms differed systematically on 3 dimensions, one of which had been highlighted experimentally for each item before the target picture was indicated. In both tasks aphasics made more errors than brain-damaged controls with respect to those features that had been stressed beforehand; they were less able than controls to take advantage of focused attention. The number of these errors was correlated with performance in the Token Test, a picture naming and a word comprehension task. There were no differences between the groups in response to variations in the semantic saliency of the discriminating features or in the semantic and phonetic relationship between words denoting the reference stimuli. The lack of interactions might have been due to a strong ceiling effect in both tasks.
