Despite a large body of research demonstrating that generalization to novel stimuli can be produced by training sufficient exemplars, the methods by which exemplars can be trained remain unclear. The purpose of the current study was to evaluate 2 methods, serial and concurrent presentation of stimuli, to train sufficient exemplars. Five preschool…

Prior research indicates that the relative effectiveness of different error-correction procedures may be idiosyncratic across learners, suggesting the potential benefit of an individualized assessment prior to teaching. In this study, we evaluated the reliability and utility of a rapid error-correction assessment to identify the least intrusive,…

Comparative studies of forward and backward chaining have led some to suggest that sensitivity to each teaching procedure may be idiosyncratic across learners and tasks. The purposes of the current study were threefold. First, we assessed differential sensitivity to each chaining procedure within children when presented with multiple learning…

We review recommendations for sequencing instruction in receptive and expressive language objectives in early and intensive behavioral intervention (EIBI) programs. Several books recommend completing receptive protocols before introducing corresponding expressive protocols. However, this recommendation has little empirical support, and some…

The personalized system of instruction (PSI) is characterized by mastery, specified objectives, self-pacing, small-step sequenced materials, repeated testing, immediate feedback, credit for success rather than penalty for errors, proctors, and lectures for motivation. Research indicating the effectiveness of PSI is cited, and problems with…

Eight adults with mild disabilities were successfully taught to write checks, complete deposit slips, and reconcile monthly bank statements using a personalized system of instruction which involved a self-paced manual, progression to new material only after demonstrating mastery of previous material, and repeated testing.
