[Free recall and recognition of semantic material--a gerontopsychologic study of a two-phase model of reproduction].

Based on a sample of N = 145 subjects, 57 to 96 years of age, the generation-recognition model of recall (12) was investigated. Using standardized word lists, a differential effect of the word frequency on free recall and recognition is shown. The assumption of separate processes in free recall is thus confirmed. The difference score from recognition and recall is shown to be age-independent and difficult to interpret as retrieval score in the framework of other performance measures.
