Patients with unilateral brain lesions of vascular origin were administered tests designed to determine if left-hemisphere specialization in manual-sequence tasks involves memory for these sequences, or performance of them, or both. Patients with left-sided lesions were worse than patients with right-sided lesions on two tasks requiring the recall of hand positions. Whereas patients with left-sided lesions showed a trend towards being worse on speeded performance of an already learned manual sequence, in both groups on this task there were a large number of failures to remember the sequence. When memory demands were better controlled by providing a model during the speeded performance task, there were no group differences. It is proposed that there is left-hemisphere specialization for memory but not performance of such motor tasks.
对患有血管源性单侧脑损伤的患者进行了测试，以确定在手动序列任务中左半球的特异性是涉及对这些序列的记忆、执行这些序列，还是两者都涉及。在两项需要回忆手部位置的任务中，左侧脑损伤患者比右侧脑损伤患者表现更差。虽然左侧脑损伤患者在已学手动序列的快速执行任务上有表现更差的趋势，但在这项任务中两组都有大量记不住序列的情况。当在快速执行任务期间通过提供一个模型更好地控制记忆需求时，两组之间没有差异。研究表明，左半球在这类运动任务中具有记忆特异性，而非执行特异性。
