Conditioned fear memories that are context-specific shortly after conditioning generalize over time. We exposed rats to a context reminder 30 d after conditioning, which served to reinstate context-specificity, and investigated how this reminder alters retrieval-induced activity in the hippocampus and anterior cingulate cortex (aCC) relative to a…

A recently recovered cumulative recorder provides a missing link in the evolution of the cumulative recorder from a modified kymograph to a reliably operating, scientifically and commercially successful instrument. The recorder, the only physical evidence of such an early precommercial cumulative recorder yet found, was sent to Keio University in…

Selected writings of B. F. Skinner are compared to 5 current topics in mainstream psychology, including the role of the unconscious, human language, the role of dispositions in psychology, human perceptions of conformity and bias, and mindfulness. The striking similarities between Skinner's work and these 5 current topics support Richelle's (1993)…

Explains how using window film is a cost-effective way to shield buildings from heat, glare, and ultraviolet rays. The pros and cons of replacement windows and window film are highlighted. (GR)

Provides tips on choosing a school heating/ventilation and air-conditioning system that meets a school's needs and budget. Discusses how to assess a school's needs and offers suggestions for making the final decision. Data tables are provided that compare various systems, including costs, maintenance, and life expectancy. (GR)

Findings provide no evidence that parent training classes in behavior modification and effective communication produce substantial differences in outcome. Interpersonal needs, rather than the type of educational module, dictate the tendency for persons to remain in the training program. (Author)

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).…

Aversive conditioning is an ideal model for studying cholinergic effects on the processes of learning and memory for several reasons. First, deficits produced by selective lesions of the anatomical structures shown to be critical for Pavlovian fear conditioning and inhibitory avoidance (such as the amygdala and hippocampus) resemble those deficits…
