Unlearning of List 1 contextual associations was studied in the verbal-discrimination nonspecific-transfer paradigm (W1-R1, Wr-,R). Bidirectional modified free-recall data revealed significant experimental unlearning of context-W (wrong item) and context-R (right item) associations, compared with both a control group that recalled immediately after List 1 practice and a 'normal forgetting' control group that recalled List 1 after working on a neutral interpolated task. In addition, an associative-matching task indicated that the experimental group also experienced unlearning of specific, incidentally learned, W-R/R-W List 1 associations. These results represent an extension to verbal-discrimination learning of several recent paired-associate studies that demonstrated unlearning of specific as well as context-item associations in the A-B, C-D paradigm. McGovern presented evidence in a study of the A-B, C-D paired-associate nonspecific-transfer paradigm that List 1 contextual associations formed between the learning context and the response items undergo extinction, or unlearning, during C-D learning.' Specific forward (A-B) and backward (B-A) associations, however, were shown to remain near criterion strength. The unlearning of context-response associations was measured in a modified free-recall task. Recall of specific associations was measured by an associative-matching task, which is assumed to eliminate the effects of item unlearning. The extinction of context-item associations was attributed to the fact that the context-response associations of the two successive lists enter into the well-documented A-B, A-C competition-unlearning relationship. Houston noted that the absence in the McGovern study of any evidence for the unlearning of specific List 1 associations could be an artifact of either (a) the overlearning of List 1 associations or (b) the failure to utilize a control group required to perform an associative-matching task after only single-list learning.2 In Received for publication October 31, 1969.
