title: Aging affects the mental simulation/planning of the "rising from the floor" sequence.
abstract: 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.
