The pressure from schools for guarenteed results are resulting in promises of performance contracting a dubious marketing strategy. (Author)

The study investigated six inferential measures of attention with 140 Ss, eight to 12 years old (with 14 learning disabled and 14 nondisabled Ss at each age level). Results indicated the measures did not consistently identify learning disabled students and did not predict classroom attending behavior. (Author/MC)

The Mean Cost Rating, P(A) from Signal Detection Theory, Kendall's rank correlation coefficient tau, and Goodman and Kruskal's gamma measures of predictive power are compared and shown to be different transformations of the statistic S. Gamma is generally preferred for hypothesis testing. Measures of association for ordered contingency tables are…

Results from the Gregorc Style Delineator (GSD), administered to 260 undergraduate nursing students, were compared with achievement scores in a human anatomy and physiology course. Factor analysis and VARIMAX rotation demonstrate that there is no relationship between any of the four learning styles allegedly identified by the GSD and achievement…

The voice quality, breathiness, hoarseness, and laryngeal strain of 20 profoundly deaf and 5 normal-hearing children, age 5-19, were judged. Findings suggest that overall prediction of voice quality cannot reliably be based on glottal parameters and judged voice deviations, although severe cases of deaf voice deviations may be detectable.…

Reviews the relevant research related to using the Rorschach, Thematic Apperception Test (TAT), and Minnesota Multiphasic Personality Inventory (MMPI) in the assessment of suicidality. Uses a case illustration to show how a battery of psychological tests can be used to identify characteristics that make an individual vulnerable to suicidal…

A model is presented that demonstrates that a random response to external constraint can produce results similar to those predicted by more complex models. Behavior that appears rational, optimal, or adaptive may truly be a random response to external constraint. Predictions based on this model may provide appropriate null hypotheses. (SLD)

The hypothesis that structured representations can be compared via structural alignment and the prediction that similarity comparisons lead subjects to attend to the matching relational structure of a pair of items were supported through 4 experiments involving 218 undergraduates. Results indicate that similarity involves alignment of structured…

This article introduces the concept of a prediction interval in a gambling context.

Three experiments examined the processing of predictive and deductive inferences elicited by narrative texts. In Experiment 1, lexical decision responses indicated that these inferences were activated during reading. In Experiment 2, sentences expressing that an event had ''maybe'' taken place were shown to be appropriate in verifying predictive…

Pigeons were trained in three experiments with a two-key, concurrent-chains choice procedure. The initial links were equal variable-interval schedules, and the terminal links were random-time schedules with equal average interreinforcement intervals. Across the three experiments, the pigeons either stayed in a terminal link until a reinforcer was…
