Proactive inhibition (PI) in motor short-term memory (STM) was investigated to determine if the PI effects commonly found in verbal STM are also present in motor STM. A simple linear positioning task was used in which a criterion position was presented to the blind-folded S (N = 72), with recall of the criterion after either 10 or 120 sec. The variable of greatest interest was the number (either 0, 2, or 4) of similar positions presented prior to the criterion, the previous positions and the criterion being recalled in reverse order following the retention interval. With 4 previous positions, Ss displayed greater absolute error and greater undershooting with algebraic error than with either 0 or 2 previous positions, indicating that PI effects were present in motor STM and that verbal and motor STM may be governed by the same set of laws.
研究了运动短期记忆（STM）中的前瞻性抑制（PI），以确定言语STM中常见的PI效应是否也存在于运动STM中。使用了一个简单的线性定位任务，向蒙眼的受试者（N = 72）呈现一个标准位置，在10秒或120秒后回忆该标准位置。最感兴趣的变量是在标准位置之前呈现的相似位置的数量（0、2或4个），在保持间隔后按相反顺序回忆先前的位置和标准位置。当有4个先前位置时，与有0个或2个先前位置相比，受试者表现出更大的绝对误差和更大的代数误差下冲，表明PI效应存在于运动STM中，并且言语和运动STM可能受同一组规律支配。
