Describes a system of further structuring the discrete trial format, an approach that draws on operant conditioning principles to present standardized and consistent learning trials. A flow chart of the Standard Trial Progression and Reinforcement Hierarchy is included, and data collection approaches are suggested. (CL)

Explores several aspects of behaviorism, including its contributions to current educational practice, its recent unpopularity, and challenges to behavioral researchers in the 1980s. Seventy-two references are appended. (Author/LLS)

The paper presents guidelines for training staff to implement positive reductive procedures to decrease undesirable behaviors of their retarded students and clients. Considerations relevant to all reductive procedures are briefly discussed in the first portion of the paper, while guidelines indigenous to positive reductive procedures are discussed…

Discusses the advantages and drawbacks of heat pumps. (IRT)

Discusses the work of S. H. White, W. F. Overton and D. M. Baer. (MS)

Reviews the use of memory measures in the literature. Suggests problems with assumptions underlying Bogartz's proposed new measure. Responds to specific criticisms by claiming that Bogartz is critical of two measures that are not even used, unfamiliar with traditional conditioning theory, wrong in an assertion about traditional measures, and…

Responds to the general criticisms of Rovee-Collier, explaining a proposed new measure of infant memory in terms of four fundamental ideas earlier enumerated by Rovee-Collier and Shyi. Seeks to refute three of four specific criticisms made by Rovee-Collier, and admits a mistake related to the fourth criticism. (BC)

Investigated the role of an external clock in two temporal conditioning situations involving three-year olds. One situation required the spacing of responses to visual stimuli; the other, producing a response for a set duration. Found that the presence of the clock increased the efficiency of performance.

Ivy Tech State College uses River Falls, a shopping mall, as an enormous heating, ventilation, and air conditioning laboratory. Students spend Saturdays working with full-time technicians getting invaluable training and experience. Students see the program as a professional opportunity and a direct route to jobs. (JOW)

Infants averaging 5 weeks and 12 weeks of age were presented with object models and a live model to determine whether infants reliably responded to the models with movement-matching facial gestures. Object models produced no reliable elicitation of gestures, but the live model increased the incidence of gestures among infants of five weeks. (SH)
