REPETITION AND MEMORY STORES

Single-store memory theories predict less repetition effects with interpolated activity while 2-store theories do not. 150 undergraduates recalled 30 lists composed of 9 digits; 1 list was presented 10 times, once every 3rd list. 5 groups of Ss (n = 30) recalled immediately or delayed recall 15 or 30 sec. with and without interpolated activity, shadowing consonants. Results showed that interpolated activity reduced the recall of last-presented items and had no effect on the rate of learning. Superior repetition effects were shown by the delayed recall groups. Results were interpreted as supporting 2-store models of memory and indicating that the learning involved a search process.
