For over a century and a quarter, the science of learning has expanded at an increasing rate and has achieved the status of a mature science. It has developed powerful methodologies and applications. The rise of this science has been so swift that other learning texts often overlook the fact that, like other mature sciences, the science of…

Several recent studies have explored what Michael (e.g., 1982) termed the "value-altering" effect and the "behavior-altering" effect of motivating operations. One aspect of the behavior-altering effect that has garnered no recent attention involves changes in stimulus control produced by motivating operations. To call attention to this aspect of…

A skill essential for successful inclusion in general education settings is the ability to learn by observing others. Research, however, has documented children with autism display significant deficits in the fundamental skills necessary for observational learning. This article outlines the skills essential for observational learning from an…

The learning of the relations between discriminative stimuli, choice actions, and their outcomes can be characterized as conditional discriminative choice learning. Research shows that the technique of presenting unique outcomes for specific cued choices leads to faster and more accurate learning of such relations and has great potential to be…

Individuals with anxiety disorders often do not respond to safety signals and hence continue to be afraid and anxious. Consequently, it is important to develop paradigms in animals that can directly study brain systems involved in learning about, and responding to, safety signals. We previously developed a discrimination procedure in rats of the…

Lowenkron and colleagues (Lowenkron, 1984; 1991; 1998; 2006; Lowenkron and Colvin, 1992) describe a model that explains complex behavior using only well-established behavioral principles, concepts and terms. The model, called "joint control," is especially useful for understanding complex and delayed discriminations within a purely behavioral…

Errorless learning refers to a variety of discrimination learning techniques that eliminate or minimize responding to incorrect choices. This article describes experimental roots of errorless learning and applied errorless strategies. Specifically, previous research on stimulus fading, stimulus shaping, response prevention, delayed prompting,…

Simple discriminations are involved in many functional skills; additionally, they are components of conditional discriminations (identity and arbitrary matching-to-sample), which are involved in a wide array of other important performances. Many individuals with severe disabilities have difficulty acquiring simple discriminations with standard…

A model of conditional discrimination performance (Davison & Nevin, 1999) is combined with the notion that unmeasured attending to the sample and comparison stimuli, in the steady state and during disruption, depends on reinforcement in the same way as predicted for overt free-operant responding by behavioral momentum theory (Nevin & Grace, 2000).…

Examines the influences of behaviorist psychology on performance and instruction technologies. The basic assumptions of behaviorism are outlined, reinforcing contingencies are reviewed, conditioning is described, and such specific topics as stimulus control, behavior chaining, and successive approximation are discussed.
