The American Speech-Language-Hearing Association (n.d.) suggests that acquisition and use of augmentative and alternative communication (AAC) is dynamic and that learning multiple modalities may be beneficial particularly for those individuals with severe disabilities. Evaluation of response variability after training multiple modalities has yet…

Members (behaviors) of a response class are equivalent in that they produce the same functional reinforcer. Oftentimes, some members of a response class occur at higher rates than others. This can be problematic when the members that occur at high rates are socially inappropriate (e.g., self-injury, aggression, or disruption). The participant in…

Counterconditioning (CC) is a form of retroactive interference that inhibits expression of learned behavior. But similar to extinction, CC can be a fairly weak and impermanent form of interference, and the original behavior is prone to relapse. Research on CC is limited, especially in humans, but prior studies suggest it is more effective than…

Prior research has demonstrated the establishment of reinforcers for learning and maintenance with young children as a function of social learning where a peer and an adult experimenter were present. The presence of an adult experimenter was eliminated in the present study to test if the effect produced in the prior studies would occur with only…

Children with autism often demonstrate less variable behavior than their typically developing peers and those with other cognitive disabilities. A possible reason for lack of response variability emitted by children with autism is that they do not have a variety of response forms in their repertoire. Multiple-exemplar training through the use of…

A primary deficit seen in many children with autism, particularly those with limited verbal repertoires, is repetitive and rote verbal behavior. This type of repetitive or rote verbal behavior can be stigmatizing and may severely limit access to primary reinforcers. Therefore, it may be beneficial to attempt to increase response variability in…

Histone modifications contribute to the epigenetic regulation of gene expression, a process now recognized to be important for the consolidation of long-term memory. Valproic acid (VPA), used for many years as an anticonvulsant and a mood stabilizer, has effects on learning and memory and enhances the extinction of conditioned fear through its…

An experimental group of three institutionalized severely retarded adult males received binary tone feedback for alpha production while a control group (3) followed identical procedures without feedback. Analysis revealed significant difference between groups in alpha percentage increase over baseline, encouraging research on applications for…

In honeybees, the proboscis extension response (PER) can be conditioned by associating an odor stimulus (CS) to a sucrose reward (US). Conditioned responses to the CS, which are acquired by most bees after a single CS-US pairing, disappear after repeated unrewarded presentations of the CS, a process called extinction. Extinction is usually thought…

Five experiments were conducted to determine whether properties inherent in some training procedures may subtly influence the adaptability of skilled performance of complex tasks. The first two experiments assessed the insensitivity of low-rate performances. Examined in the third experiment was the issue of whether instructions that focus…

Article discusses selected observations on behaviorally oriented approaches to counseling, defines behavioral counseling, and examines current techniques. (Author/RK)

The treatment of a 10-year-old elective mute boy is reported in detail. A learning principles based approach was used in a one-to-one therapeutic setting. Relatively normal speaking patterns were established after 15 months of treatment. (Author)

Conflicting evidence as to the presence or absence of generalization in classroom behavior modification programs prompted this study of the conditions of generalization. During the experiment, behaviors operationally defined as competitive or cooperative were reinforced in certain game situations. Then the generalization of this training over…

Describes a computer tutorial that teaches the fundamentals of stimulus generalization in operant learning. Concepts covered include reinforcement, discrimination learning, stimulus continua, generalization, generalization gradients, and peak shift. The tutorial also reviews applications in human and animal situations. The content is appropriate…
