Spatial representations in older adults are not modified by action: Evidence from tool use.

摘要: Theories of embodied perception hold that the visual system is calibrated by both body schema and action system, allowing for adaptive action-perception responses. One example involves effects tool use on distance perception, in which wielding a with intention to act upon target appears bring object closer. This tool-based spatial compression (i.e., tool-use effect) has been studied exclusively younger adults, but it unknown whether phenomenon exists older adults. In this study, we examined adults 2 experiments. Experiment 1, estimated distances targets just beyond peripersonal space while either or pointing hand. Younger not be closer after reaching tool. 2, remote using baton laser pointer. displayed pointer compared baton, although did not. Taken together, these findings indicate generalized absence effect during estimation, suggesting visuomotor does remap from extrapersonal representations use.
