The present study investigated modularity of object and place memory in children with the reaction time/accuracy paradigm. The memory task was presented in two spatial arrays, a frame with landmarks and a grid. Modularity was tested using perceptual size judgment (what-interference) and movement direction judgment (where-interference). Latencies of object memory were increased by same-system what-interference in all age groups indicating limited capacity of an object memory system. With respect to accuracy of object and place memory, only young children's performance was susceptible to same-system interference of perceptual judgment.
本研究采用反应时间/准确性范式，对儿童物体和空间记忆的模块化进行了调查。记忆任务呈现在两个空间阵列中，一个带有地标的框架和一个网格。使用感知大小判断（“什么”干扰）和运动方向判断（“哪里”干扰）来测试模块化。在所有年龄组中，同一系统的“什么”干扰都会增加物体记忆的潜伏期，这表明物体记忆系统的容量有限。关于物体和空间记忆的准确性，只有幼儿的表现容易受到感知判断的同一系统干扰。
