If intentional forgetting is to be understood, research must focus on the specification of exactly how memory search and decision processes are altered when a subject is instructed to forget. This research addresses that problem. (Author/RK)

Tulving and others (Tulving, 1974; Tulving & Madigan, 1970) have distinguished two kinds of forgetting of verbal information: trace-dependent forgetting and cue-dependent forgetting. Attempts to determine which type occurs in retroactive inhibition of free-recall learning. (Author/RK)

Attempts to define the relationships between four measures of recall in a two-recall task, namely (a) initial short-term recall (STR), (b) unconditional final free recall (FFR), (c) final free recall conditionalized on an initial successful recall (FFR/STR), and (d) final free recall conditionalized on an unsuccessful recall (FFR/STR).

A general decision-theory analysis of the word-frequency effect in recognition memory is carried out. On the basis of the analysis and data from a forced-choice experiment two distinct causes of the frequency effect are defined. (Editor)
