How does learning the timing of actions influence our ability to learn the order of actions? A sequence of responses cued by spatial stimuli was learned in a serial reaction time task where the response-to-stimulus intervals (RSIs) were random, constant, or followed a fixed sequence. In this final sequenced-RSI condition, the response and RSI sequences were consistently matched in phase and could be integrated into a common sequence representation. The main result was that the response sequence was learned to a similar degree in all RSI training conditions, indicating that neither the predictability of RSIs nor the integration of the phase-matched response and timing sequences benefited learning of the response sequence. Nevertheless, temporal learning and integration speeded up performance without strengthening the representation of response order.
学习动作的时间安排如何影响我们学习动作顺序的能力?在一项序列反应时任务中,被试学习由空间刺激提示的一系列反应,其中反应与刺激间隔(RSIs)是随机的、恒定的或遵循固定序列。在这种最终的序列RSI条件下,反应序列和RSI序列在相位上始终匹配,并且可以整合到一个共同的序列表征中。主要结果是,在所有RSI训练条件下,反应序列的学习程度相似,这表明RSIs的可预测性以及相位匹配的反应序列和时间序列的整合都没有促进反应序列的学习。然而,时间学习和整合加快了表现,但没有加强反应顺序的表征。
