Effect of four different delay periods on recall of the Rey-Osterrieth complex figure by older persons

Abstract
We examined the effect of four different delay periods (15, 30, 45, or 60 min.) on recall of the Rey-Osterrieth Complex Figure (ROCF) in older persons. The 60 subjects were divided into four groups of 15; the groups were equivalent in age, sex, and education. All subjects received the standard copy and immediate recall trials of the ROCF, followed by one of the four delay durations. There were no significant differences between the groups on copy, immediate, or delayed recall trials. Thus, minor variations in delay period did not have significant effects on recall.
