A theoretical model for estimating the effects of age and incentive on children's performance in probability learning is introduced. Novel predictions of the model about the effects of combinations of age and incentive were tested and confirmed. (Editor/RK)

The possibility that subjective contours are an artifact of brightness contrast was explored. Concludes that subjective contour and brightness contrast are distinct perceptual phenomena but share a dependency on the processing of edge information transmitted through the achromatic channels of the visual system.

Rats performed an intermittently reinforced operant response and received periodic presentations of a visual conditioned stimulus (CS) located either very near or far from the operant manipulandum. Findings suggest there are deficiencies in the general accounts of conditioned suppression that stress the motivational or emotional effects of…

The negative-contrast effect occurs when animals that are shifted from large to small reward temporarily drop below small reward control groups. The basic question asked here in three experiments was whether animals tested under a specific drive level will behave as though they expect a reward magnitude previously received, depending on the reward…

Assesses the validity of physiological versus learning interpretations of illness-preexposure effects. (Author/RK)

Uses an innocuous tone as the imperative stimulus, or unconditioned stimulus, as in a forewarned reaction time situation but with no overt response required. Evidence of conditioning and generalization to words is obtained. (Editor/RK)

Concerns the examination of conditioned stimulus--unconditioned stimulus (CS--UCS) intervals of different lengths. Demonstrates the feasibility of using a forewarned reaction time procedure with an innocuous imperative stimulus for the investigation of classical conditioning. (Editor/RK)

Considers the hypothesis that thought results in the "reinterpretation" of inconsistent beliefs so as to make them more consistent with the initial attitude direction. The resulting cognitions, being more univocal would, in turn, produce attitude polarization. (Author/RK)

Discusses the effectiveness of using prompting in computer assisted instruction and time delay fading of such prompts to teach new skills to students who have difficulty learning by traditional methods. A CAI tutorial program which uses these techniques to teach time-telling skills is described. (MBR)

Presents flow chart of the process of psychotherapy with couples as way for practitioners to integrate various models of marital therapy into their treatment. Discusses sequentially basic steps and questions to be addressed; resolution of each stage is considered important for movement to following stages. Notes flow chart allows intervention…

Discusses shortcomings of a computer program previously described (Electronic Library, April 1985) to create Keyword Out of Context (KWOC) indexes. Program modifications are described which allow indexers to edit terms as the index is being compiled so term consistency is achieved and language conventions are observed. Examples are presented. (MBR)

The use of syntax flow charts as a graphic illustration of syntactic rules is suggested as both an instructional and a heuristic tool. Charts for these French structures are presented: negating of verbal expressions; balancing of conditional tenses; use of imperfect versus compound; agreement of past participles; and subjunctive sequences. (MSE)

A review of selected experiments indicates that not all examples of experimental amnesia are due to the failure of a memory to fixate. In sum, the empirical retrograde amnesia gradient does not necessarily support traditional consolidation theory. (Editor)
