Five profoundly mentally retarded adolescents and adults were taught to respond to an auditory-visual complex stimulus. Later, the auditory component alone was presented, and three subjects did not respond. These subjects then received a fading program which successfully established auditory stimulus control with two subjects. (MSE)

A survey of 55 Louisiana members of the American Association on Mental Retardation (AAMR) indicated disagreement with an AAMR position statement condemning inhumane forms of aversive therapy. AAMR is urged to reconsider its position concerning the scope of aversive therapy, need for further research, and use of aversive therapy with some…

Evidence that the vigor of the startle reflex varies systematically with the organism's emotional state is reviewed. A theory elucidating this relationship suggests how amplitude of eyeblink response to a probe may be modulated by affective content of perception and thought. Implications for research on emotion are outlined. (SLD)

Four young children were taught contact lens wear using a shaping procedure, which involved praise and tangibles for compliance and time-outs or restraint for noncompliance. At followup, levels of compliance were high for three children, while a subject with Down's syndrome showed low compliance with need for physical restraint throughout.…

This study tested whether conditioning to one member of a compound stimulus can be blocked by presence of a second member to which the response was previously conditioned. Eight mentally retarded students (ages 7-9) were presented with words, sometimes accompanied by pictures. Six students performed best when words were presented without pictures.…

This study examined the use of air-puff conditioning audiometry in the hearing assessment of 12 multiply handicapped (including severe/profound mental retardation) subjects, ages 9-32. Ten subjects reached criterion conditioning and then completed the hearing assessment with the air-puff procedure while one reached criterion with a modified…

This article reviews the theoretical and research literature on vision stimulation and vision training of children with severe irreversible visual impairments. It recommends early stimulation to prevent visual deprivation, use of operant conditioning, and the presentation of highly contrasting stimuli to stimulate visual awareness in children with…

Contends that, although the operant approach to psychology is based on objective empirical observations, much of psychology is filled with subjective, interpretive terminology. Argues that such terminology produces confusion over the definitions of basic operant concepts. Suggests a solution that defines the concepts of positive and negative…

Examines a Florida Montessori school design that does not use air conditioning and is naturally lighted. Discusses design considerations that took advantage of natural surroundings, the architectural approach that helped bring the outdoors closer to the classroom, and the environmental pay-off. (GR)

A study examined sensitivity to reinforcement in two boys (ages 7-10) with attention deficit hyperactivity using the matching law and evaluated effects of methylphenidate. In the medicated condition, the matching function for both subjects resulted in higher asymptotic values, indicating an overall elevation of behavior rate under these…

Based on one school district's experience, discusses raised access flooring systems for schools. Addresses the nuts and bolts of such flooring systems, integrating an air delivery system below the flooring, advantages of floor-level air supply, and design issues. (EV)

Restructuring an existing token economy (TE) in a psychiatric facility for children led to increased point-earning and decreased daily trips to seclusion. Restructuring occurred through operationalization of target behaviors and reduction of time between receipt of reinforcers and opportunity to exchange tokens. Results suggest changes in basic…

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…

The basolateral amygdala's involvement in fear acquisition and expression to visual and auditory stimuli is well known. The involvement of the basolateral and other amygdala areas in fear acquisition and expression to stimuli of other modalities is less certain. We evaluated the contribution of the basolateral and medial amygdala to olfactory and…

We recently reported that fear extinction, a form of inhibitory learning, is selectively blocked by systemic administration of L-type voltage-gated calcium channel (LVGCC) antagonists, including nifedipine, in mice. We here replicate this finding and examine three reduced contingency effects after vehicle or nifedipine (40 mg/kg) administration.…
