List Organization and Retroactive Inhibition in Free Recall.
Andre, Thomas; And Others
An experiment was conducted to test the generalized response suppression hypothesis by comparing the amounts of retroactive inhibition for items whose retrieval cue was the same on both lists to the retroactive inhibition for items whose retrieval cues were different on the two lists. Subjects were 56 adults randomly assigned to experimental groups of 14. Groups were instructed to use either alphabetical or free recall, or alphabetic or clustering organization when learning successive lists of nouns. Alphabetic instructions produced faster learning than free recall instructions; alphabetic and clustering instructions did not differ. Groups that used the same organization on both lists recalled fewer items than groups that used different organizational strategies, which indicates that organizational overlap was the source of interference. In each experiment, the first letters of half the items were repeated on both lists; the first letters of the remaining items were unique. Groups that alphabetized both lists recalled fewer words with duplicated than non-duplicated initial letters, a fact suggesting item-specific interference rather than generalized suppression of first-list responses.
