Evidence indicates that the newborn infant must first develop cognitive systems, through his experience with various stimuli, to differentiate each modality separately before he can integrate any two modalities in classical conditioning. (Author/NH)

A simple extension of a network model of conditioning developed by N. Schmajuk and J. Di Carlo (1992) is applied to descriptions of two different conditioned stimulus (CS) functions: (1) a simple CS eliciting conditioned responses by signaling the occurrence of an unconditioned stimulus; and (2) an occasion setter controlling the responses…

An experiment is reported in which the effect of unconditioned stimulus (US) intensity on latent inhibition (LI) was examined, using a two-stage conditioned emotional response (CER) procedure in rats. A tone was used as the pre-exposed and conditioned stimulus (CS), and a foot-shock of either a low (0.3 mA) or high (0.7 mA) intensity was used as…

Several researchers have suggested that conditioning history may have long-term effects on fixed-interval performances of rats. To test this idea and to identify possible factors involved in temporal control development, groups of rats initially were exposed to different reinforcement schedules: continuous, fixed-time, and random-interval.…

Eleven institutionalized psychotic children 4- to 13-years-old received 13 weeks of traffic safety training using operant conditioning. (CL)

Scientifically validated methods of reducing tension and alleviating tension disorders are reported in the papers presented at this convention. Treatment for the physical manifestations of anxiety such as sleeplessness, speech difficulties, and forgetfulness is described in several papers. The effectiveness of hypnosis and coordination of the…

Research on learning and conditioning suggests that verbal response modification does not occur in the absence of the subject's ability to define verbally (1) the response-reinforcement relationships and (2) his intention to change his behavior in the direction of reinforcement. This seems to be true for operant conditioning of verbal behavior,…

A comprehensive discussion of single fuel source generation of power and heating requirements is presented. Definition and explanation of system concepts includes--(1) heat pumps, (2) steam turbines, (3) gas turbines, and (4) gas and diesel engines. Concept cost evaluation factors described are--(1) load pattern, (2) campus configuration, (3) fuel…

Modern behavioral scientists have emphasized the importance of environmental influences in human behavior. If the basis for behavior development and change rests within the environment, an understanding and use of the methods of control by change agents, especially teachers, can result in more prosocial behavior. Planned reinforcement could…
