本研究的目的是探讨实际动作和想象动作的执行时间和执行顺序的变化对想象动作持续时间的影响。两组受试者必须实际执行和想象一个行走和一个写作任务。第一组首先进行10次实际运动的试验（A组），然后在不同的时间间隔想象相同的运动：在实际运动后立即（I-1组）和25分钟（I-2），50分钟（I-3）和75分钟（I-4）的间隔。第二组首先想象，然后实际执行任务。实际的和想象的运动，记录的电子秒表由受试者操作的持续时间进行了分析。想象的运动的持续时间是非常相似的那些实际的运动，对于这两个任务，无论是从实际运动（第一组）或性能（第二组）的顺序间隔过去。然而，想象的运动持续时间的变异性显着增加相比，实际运动的变异性，运动任务和组。这些发现证明了类似的认知过程，这些认知过程是想象和实际运动表现的基础。
The purpose of the present study was to investigate the effects on the duration of imagined movements of changes in timing and order of performance of actual and imagined movement. Two groups of subjects had to actually execute and imagine a walking and a writing task. The first group first executed 10 trials of the actual movements (block A) and then imagined the same movements at different intervals: immediately after actual movements (block I-1) and after 25 min (I-2), 50 min (I-3) and 75 min (I-4) interval. The second group first imagined and then actually executed the tasks. The duration of actual and imagined movements, recorded by means of an electronic stopwatch operated by the subjects, was analysed. The duration of imagined movements was very similar to those of actual movements, for both tasks, regardless of either the interval elapsed from the actual movements (first group) or the order of performance (second group). However, the variability of imagined movement duration was significantly increased compared to variability of the actual movements, for both motor tasks and groups. The findings give evidence of similar cognitive processes underlying both imagination and actual performance of movement.
