The present study examined haptic and visual memory capacity for familiar objects through the application of an intentional free-recall task with three-time intervals in a sample of 78 healthy older adults without cognitive impairment. A wooden box and a turntable were used for the presentation of haptic and visual stimuli, respectively. The procedure consisted of two phases, a study phase that consisted of the presentation of stimuli, and a test phase (free-recall task) performed after one hour, one day or one week. The analysis of covariance (ANCOVA) indicated that there was a main effect only for the time intervals (F (2,71) = 12.511, p = .001, η² = 0.261), with a lower recall index for the interval of one week compared to the other intervals. We concluded that the memory capacity between the systems (haptic and visual) is similar for long retrieval intervals (hours to days).

本研究通过在 78 名没有认知障碍的健康老年人的样本中应用 3 次间隔的有意自由回忆任务，检查了熟悉物体的触觉和视觉记忆能力。木箱和转盘分别用于呈现触觉和视觉刺激。该过程由两个阶段组成，一个是由呈现刺激物组成的研究阶段，另一个是在一小时、一天或一周后执行的测试阶段（自由回忆任务）。协方差分析 (ANCOVA) 表明仅对时间间隔有主效应 (F (2,71) = 12.511, p = .001, η ² = 0.261)，与其他间隔相比，一周间隔的回忆指数较低。我们得出结论，系统（触觉和视觉）之间的记忆容量对于长检索间隔（数小时到数天）是相似的。
