Abstract

This study investigated the end-state comfort (ESC) effect in adults with intellectual disabilities (ID). The ESC effect represents a tendency to maximize comfortable hand and arm postures at the end of an object manipulation task. Participants were 22 adults with non-specific ID. The ESC effect was assessed using a simple object manipulation task. Difficulties were found with manifestation of the ESC effect in adults with non-specific ID. Only four participants displayed the ESC effect. The participants’ intellectual function was correlated with expression of the ESC effect. These results were assessed in terms of competition between a goal-directed system and habitual systems in adults with ID.

摘要

这项研究调查了智力障碍（ID）成年人的最终状态舒适度（ESC）效果。ESC效果代表在对象操作任务结束时最大化手和手臂舒适姿势的趋势。参加者为22位具有非特定ID的成人。使用简单的对象操作任务即可评估ESC效果。发现具有非特异性ID的成年人存在ESC效应表现的困难。只有四位参与者展示了ESC效果。参与者的智力功能与ESC效应的表达相关。根据ID成年人的目标导向系统和习惯系统之间的竞争，对这些结果进行了评估。
