Abstract
In a 4 × 2 × 2 × 2 randomized groups design, the effects of the independent variables method of training (correction, rerun-correction, noncorrection, and rerun-noncorrection), type of apparatus (parallel alley maze and T-maze), position preference (preference and nonpreference), and type of problem (position response and brightness discrimination), on the dependent variables of trials, errors, correct responses, and runs, during acquisition and extinction were studied. In acquisition, training methods, tasks, and preferences showed significant effects on all dependent variables. There were no significant results in the extinction data. Since Ss run under noncorrection procedures required fewer reinforcements to reach criterion, this seems the most efficient training technique. These data are interpreted as underscoring the importance of careful consideration of experimental procedure and definition of variables when comparing results from different studies in animal learning.
