Children's spatial mapping starts out particularly sensitive to 3D wall-like boundaries and develops over early childhood to flexibly include other boundary types. This study investigated whether spatial boundaries influence children's episodic memory, as in adults, and whether this effect is modulated by boundary type. Eighty-one Korean children (34 girls, 36–84 months old) re-enacted a sequence of three discrete hiding events within a space containing one of three boundaries: 3D wall, aligned objects, or 2D line. Children's memory of events occurring on one side of the boundary developed earlier than those that crossed the boundary. At first, this interaction only applied to the 3D wall and extended to other boundary types with age, suggesting that children's changing spatial representations influence their episodic memory development.

空间边界对情景记忆发展的影响

儿童的空间映射开始时对 3D 墙状边界特别敏感，并在儿童早期发展到灵活地包含其他边界类型。本研究调查了空间边界是否像成人一样影响儿童的情景记忆，以及这种影响是否受边界类型的调节。81 名韩国儿童（34 名女孩，36-84 个月大）在包含三个边界之一的空间内重新制定了一系列三个离散的隐藏事件：3D 墙、对齐的对象或 2D 线。儿童对发生在边界一侧的事件的记忆比那些越过边界的事件发展得更早。起初，这种交互只适用于 3D 墙，并随着年龄的增长扩展到其他边界类型，这表明儿童的
