Distribution of practice effects: Changes from one testing to the next. All cognitive domains (respective single tests grouped as described in Figure 2) show most pronounced improvement in performance from baseline to the 2nd testing time-point. At late testing time-points with long intertest intervals (5th to 6th, and 6th to 7th testing), test scores show a slight tendency to decrease. Mean of % change given. Lines indicate logarithmic trends.
