The [delta] subunit of the GABA[subscript [Alpha]] receptor (GABA[subscript [Alpha]]R) is highly expressed in the dentate gyrus of the hippocampus. Genetic deletion of this subunit reduces synaptic and extrasynaptic inhibition and decreases sensitivity to neurosteroids. This paper examines the effect of these changes on hippocampus-dependent trace…

After training conditional discriminations among selected stimuli from two perceptual classes, the emergence of novel relations involving other members of both classes was assessed using cross-class probes. The cross-class probes were presented using one of four different testing schedules. In the 2/9 test, nine different probes were presented in…

Background: The conclusion from a vast literature on literacy acquisition is that letter knowledge is one of the best predictors of literacy development. The question of the best way to teach children letter sounds has not, as yet, been answered satisfactorily. Aims: The aim of this study was the evaluation of a computer training program using…

This military-developed text consists of three blocks of instructional materials for use by those studying to become refrigeration and air conditioning specialists. Covered in the individual course blocks are the following topics: refrigeration and trouble analysis, thermodynamics, and principles of refrigeration; major components and domestic and…

This plan of instruction, study guides, workbooks, and programmed texts for a secondary-postsecondary-level course in refrigeration and air conditioning are one of a number of military-developed curriculum packages selected for adaptation to vocational instruction and curriculum development in a civilian setting. It is the first section of a…

Provides an overview of the current methods of behavior modification, reviews some critical issues, such as fear of control, use of aversive control, and behavior modification in prisons, in an effort to aid in differentiating warranted from unwarranted concerns. Ethical standards and practices are discussed. (Author/AM)

Thirty college students and 30 moderately retarded persons averaging approximately equal age received eight alternating phases of acquisition and extinction trials with an electric pulse as the unconditioned stimulus for classical eyelid conditioning. (Author)

This study investigates the efficacy of symbolic modeling and role-playing therapy in the reduction of avoidance behaviors. After treatment, role-playing subjects demonstrated significantly less avoidance behavior and lower subjective fear ratings than the modeling or control group subjects. (Author/SJL)

The long-term treatment program and follow-up of a case of chronic, severe, multiple self-injurious behavior is presented. Contingent electric shock and differential reinforcement of other behavior were the primary techniques utilized. Total suppression was achieved in the laboratory setting, but extending control to the natural environment proved…

In a two part article the author first discusses the importance of fluency, rate, breathstream management, prosody, and self-confidence to the replacement of stuttering with normal speech; and second outlines specific clinical procedures for achieving these goals with adult and adolescent stutterers. (Author/LS)

Examined was the effect of operant-conditioning on the pica behavior (eating inedible substances) of a 14-year-old severely retarded institutionalized boy. (CL)

The effects and side effects of overcorrection for self-stimulatory behaviors of two children, who had been diagnosed as schizophrenic in a specialized day care program were evaluated. (Author)

To determine the influence of successful or unsuccessful competitive outcomes and small or large margins of victory/defeat on performance, pairs of female undergraduate students "competed" against each other in a dart tossing contest. False feedback about the outcomes and margin of victory/defeat led subjects to believe they were winning every…

William James, the turn of the century psychologist, philospher, and educator, was avidly interested in the relationship between psychology and teaching. This paper considers operant conditioning, timing of reinforcers, and programmed instruction--touchstones of B.F. Skinner in the teaching/learning milieu. Of course, materials not just methods…

The heat collecting capacity of the earth and or the earth's ground waters and surface waters exist as potential energy sources for home heating and cooling. Techniques and devices associated with use of the earth's thermal energy capabilities are presented and evaluated in this four-chapter report. Included in these chapters are: (1) descriptions…
