Data AnalysisData Analysis

The real goal of this demonstration was to give you varying amounts of maintenance (Type I) rehearsal and see what effect that would have on memory.

Some words were only to be rehearsed for one position (one second) up to five positions (five seconds).

What difference might this make?
