Modulating peripersonal and extrapersonal reach space via tool use: a comparison between 6- to 12-year-olds and young adults.

摘要

This study examined age-related characteristics associated with tool use in the perception and modulation of peripersonal and extrapersonal space. Seventy-six (76) children representing age groups 7-, 9-, 11?years and 36 adults were presented with two experiments using an estimation of reach paradigm involving arm and tool conditions and a switch-block of the opposite condition. Experiment 1 tested Arm and Tool (20?cm length) estimation and found a significant effect for Age, Space, and an Age?×?Space interaction (ps?
