Recall as a function of orienting task and retrieval cue

Abstract.— In an incidental learning experiment, a 40 word list with 4 words representing each of 10 taxonom-ic categories and beginning with each of 10 first letters was presented to 120 subjects. Half the subjects sorted the words according to category, half according to initial letter. After an interval of either 1 or 6 min, retention was measured with cued or free recall tests. The subjects in the Category sort-Category cue condition obtained higher recall than the subjects in the Category sort-Letter cue condition, whereas level of recall did not differ between the Letter sort-Letter cue and Letter sort-Category cue conditions. These results together with other results from the experiment were considered as arguments against the Encoding Specificity Principle but in favor of a theory separating encoding from retrieval.
