Abstract
Investigations of a new experimental variable from the arrangements of reinforcements (R) and tests (T) in paired-associate learning were furthered by a 2 × 2 × 2 factorial experimental design: 64 college students learned two lists of 12 pairs, one with unmixed list (Exp. I) and the other with mixed list (Exp. II). Four repetitive experimental sequences in each experiment were RTRT …, RRTRRT. … RTTRTT …, and RRTTRRTT. … No significant differences were found between mixed- and unmixed-list designs for any given statistic examined. The findings indicate that individual pairs in a given condition were learned relatively independently of those in the other conditions within a list. The present results were close replications of the previous study by Izawa (1966a) and support the stimulus fluctuation model.Keywords
