We investigated the effect of aging on the ability to mentally simulate/plan a complex sequential action of the whole body, namely "rising from the floor". Forty-four non-demented elderly people (mean age: 85.2±5.5 years) and 20 young people (mean age: 26.6±4.9 years) were included in the study. They were required to put in order six images representing the main movements necessary to get up from a sitting position on the floor. We showed that older subjects had poorer performance-both in terms of proportion of success and response time-than their younger counterparts. These results are in line with previous findings showing age-related alterations in action simulation/action planning processes, and highlight the fact that elderly people have particular difficulties when the action to mentally simulate is complex.
我们研究了衰老对心理模拟/规划全身复杂连续动作能力的影响，即“从地板上站起来”。该研究纳入了 44 名认知正常的老年人（平均年龄：85.2±5.5 岁）和 20 名年轻人（平均年龄：26.6±4.9 岁）。他们需要按照顺序排列代表从地板上坐起所需的主要动作的六张图片。我们发现，与年轻参与者相比，老年人的表现较差——无论是在成功比例还是反应时间方面。这些结果与先前表明与年龄相关的动作模拟/动作规划过程改变的发现一致，并强调了这样一个事实，即当需要心理模拟的动作复杂时，老年人特别困难。
