Middle childhood is a transitional period for episodic memory (EM) performance, as a result of improvements in strategies that are used to encode and retrieve memories. EM is also a skill continually assessed for testing in the school setting. The purpose of this study was to examine EM performance during middle childhood and its relation to individual differences in attentional abilities and in neurophysiological functioning. We examined self-reports of attention at 6, 7 and 8-years of age as well as parietal EEG recorded during baseline, memory task encoding, and memory task retrieval. Results indicate that child self-reports of attention predicted EM performance. Additionally, the difference from baseline to retrieval-related EEG activation contributed variance to EM performance. Results replicate other middle childhood studies showing a positive association between EM performance and attention while also suggesting that parietal EEG yields critical information regarding memory performance.

童年中期的情景记忆:年龄、脑电活动和自我报告的注意力

由于用于编码和检索记忆的策略的改进,童年中期是情景记忆 (EM) 表现的过渡期。EM 也是一项持续评估以在学校环境中进行测试的技能。本研究的目的是检查童年中期的 EM 表现及其与注意力能力和神经生理功能的个体差异的关系。我们检查了 6、7 和 8 岁时的自我注意力报告以及基线、记忆任务编码和记忆任务检索期间记录的顶叶脑电图。结果表明,儿童对注意力的自我报告预测了 EM 表现。此外,从基线到检索相关 EEG 激活的差异导致了 EM 性能的差异。
