One purpose was to obtain evidence as to whether either learning or forgetting occurs on unreinforced T trials; a second was to adduce principles bearing on the problem of optimal programming of R and T trials. The four training conditions were: (1) R T R T ... ; (2) R R T R R T ... ; (3) R T T R T T ... ; (4) R R T T R R T T ... Five items were assigned to each condition and the sequences were repeated till a criterion of learning was reached. Two groups of 50 subjects were run; one with nonsense syllable-number pairs and one with nonsense syllable-word pairs. Performance on tests given successively without intervening reinforcement showed no significant change in correct response probability--suggesting that neither learning nor forgetting occurred on T trials per se. The course of learning was, however, affected to a major extent by the ratio of Ts to Rs and by their arrangement in the various repetitive sequences. Learning curves plotted in terms of error proportion on the first T following the n(th) R trial lined up in the order: Condition 3 (lowest), 1, 4, 2. (Author).
