将个体暴露于先前事件的孤立成分(素数)会加速其遗忘。两项针对120名3至18个月大的婴儿的实验确定了可以重新激活遗忘记忆的启动时间的最短持续时间以及重新激活的记忆持续多久。婴儿学会了一个操作性任务,忘记了它,暴露在启动,后来被测试为重新保留。在实验1中,有效启动的最短持续时间随着年龄的增长而递减,但总是比仅仅看一眼的持续时间长。在实验2中,重新激活的记忆在最短持续时间的启动后被遗忘的速度是在全长启动后的两倍,与启动延迟和婴儿年龄无关。这些数据表明,最小有效的启动持续时间在心理学上等同于遗忘记忆的可访问性。我们的结论是,启动是感知的基础上,组织的比例(日志)规模的影响。© 2005威利期刊有限公司Dev Psychobiol 47:43-54,2005.
Exposing individuals to an isolated component (a prime) of a prior event alleviates its forgetting. Two experiments with 120 human infants between 3 and 18 months of age determined the minimum duration of a prime that can reactivate a forgotten memory and how long the reactivated memory persists. Infants learned an operant task, forgot it, were exposed to the prime, and later were tested for renewed retention. In Experiment 1, the minimum duration of an effective prime decreased logarithmically with age, but was always longer than the duration of a mere glance. In Experiment 2, the reactivated memory was forgotten twice as fast after a minimum‐duration prime as after a full‐length one, irrespective of priming delay and infant age. These data reveal that the minimum effective prime duration psychophysically equates the accessibility of forgotten memories. We conclude that priming is perceptually based with effects that are organized on a ratio (log) scale. © 2005 Wiley Periodicals, Inc. Dev Psychobiol 47: 43–54, 2005.
