We investigated memory encoding and retrieval during a quasinaturalistic spatial-episodic memory task in which subjects delivered items to landmarks in a desktop virtual environment and later recalled the delivered items. Transition probabilities and latencies revealed the spatial and temporal organization of memory. As subjects gained experience with the town, their improved spatial knowledge led to more efficient navigation and increased spatial organiza... ...点击完成人机验证后继续浏览

我们研究了在准自然的空间情景记忆任务中记忆编码和检索的过程，在该任务中，受试者在一个桌面虚拟环境中将物品送到地标，并在之后回忆起所送的物品。转移概率和延迟揭示了记忆的空间和时间组织情况。随着受试者对该城镇的经验增加，他们对空间知识的提高导致导航效率更高以及回溯时空间组织更明显。表现出更强空间组织的受试者在时间组织上则表现较弱。头皮记录的脑电图信号显示了成功的编码和检索的频谱相关性。成功编码伴随着θ波功率（T+）增加和α/β波功率（A-）减少，而在成功检索时还伴有γ波（G+）增加。基于频谱特征训练的逻辑回归分类器能够可靠地预测未见会话中的记忆成功情况。单变量和多变量脑电图分析揭示了成功的记忆具有类似的θ波增强、α/β波减弱以及γ波增强的频谱特征。这些发现将成功的编码和检索的行为及神经标志扩展到了在时空背景下进行学习的自然任务中。（PsycInfo数据库记录 © 2024 APA，保留所有权利）。
