Abstract
The present study investigated age differences in constructive activity, using three different tasks: the Rey-Osterrieth Complex Figure, Block Design, and Benton's 3D Construction tests. Participants were 116 healthy adults, ages ranging from 25 to 74 years. Results of the ROCF test failed to show any age difference in test scores among the participants up to early 60's, task completion time among those up to early 50's, and strategy among all participants. However, results of the Block Design test showed age differences in test score, task completion time, and strategy among all participants. Results of the 3D Construction test failed to show any age difference in test score among the participants up to early 60's, task completion time among those up to early 50's, but showed age differences in strategy among all participants. These findings suggest that it is necessary to take into account task-specific age differences in constructive skills, when evaluating constructive disabilities.
