Chapter 4 Discussed a Classic Study by Wickens and His

Chapter 4 discussed a classic study by Wickens and his colleagues (1976) in which each of five groups of participants learned a series of words belonging to one category (e.g., "occupations" or "meats") . On the final trial, they all switched to words belonging to a new category ("fruits") . What did the results of this study show about the recall for this final set of words?

A) Contrary to expectations, semantic similarity had no influence on recall.
B) Contrary to expectations, participants explained that they stored these final words in terms of visual images.
C) Participants in all five groups showed no release from proactive interference.
D) Recall on the final set of words was most accurate when the previous items had belonged to a different semantic category.
