Temporal memory in 7-year-olds, 10-year-olds, and young adults (N = 78) was examined introducing a novel eye-movement paradigm. Participants learned object sequences and were tested under three conditions: temporal order, temporal context, and recognition. Age-related improvements in accuracy were found across conditions; accuracy in the temporal conditions was correlated with conventional time knowledge. Eye movements tracked the veridicality of temporal order memory in adults and 10-year-olds seconds before providing memory judgments, suggesting that these movements reflect implicit access to temporal information. Seven-year-olds overall did not show this eye-movement effect, but those who did were more accurate than those who did not. Results suggest that eye movements capture aspects of temporal memory development that precede overt decision processes-with implications for hippocampal development.
对 7 岁、10 岁和年轻成年人(N = 78)的时间记忆进行了研究,引入了一种新的眼动范式。参与者学习物体序列,并在三种条件下进行测试:时间顺序、时间上下文和识别。在所有条件下,年龄相关的准确性都有所提高;时间条件下的准确性与传统的时间知识相关。在为记忆判断提供信息之前的几秒钟内,成年人和 10 岁儿童的眼动跟踪了时间顺序记忆的真实性,这表明这些运动反映了对时间信息的隐性访问。7 岁儿童总体上没有表现出这种眼动效应,但那些表现出这种效应的儿童比那些没有表现出这种效应的儿童更准确。研究结果表明,眼动可以捕捉到时间记忆发展的各个方面,这些方面先于明显的决策过程——这对海马体的发展有影响。
