三个实验研究了练习对18个月大婴儿记忆能力的影响。婴儿使用模仿范式进行测试;一个成年人展示了一系列的动作与对象和婴儿有机会重现这些行动后，延迟。一些婴儿在保持间隔之前练习了目标动作（练习），而另一些则没有（没有练习）。在实验1中，提醒治疗减轻了遗忘的婴儿谁练习，但未能减轻遗忘的婴儿谁不练习。在实验2A和2B中，练习的婴儿在24小时的延迟后对新的测试刺激进行了概括，而没有练习的婴儿则没有。结果表明，实践影响婴儿的记忆的可及性和概括性。
Three experiments examined the effect of practice on memory performance by 18-month-old infants. Infants were tested using an imitation paradigm; an adult demonstrated a series of actions with objects and infants were given the opportunity to reproduce those actions following a delay. Some infants practiced the target actions before the retention interval (practice) and some did not (no practice). In Experiment 1, a reminder treatment alleviated forgetting by infants who practiced but failed to alleviate forgetting by infants who did not practice. In Experiments 2A and 2B, infants who practiced generalized to novel test stimuli after a 24-hr delay, whereas infants without practice did not. Results suggest practice influences the accessibility and generality of infants' memories.
