The aim of this study was to examine pattern difficulty as a general factor influencing orientation errors, and to explore psychological differentiation and task perception as variables accounting for cross-cultural differences. Samples of 30 boys and 30 girls in Ghana and Scotland were tested. (Editor)

Professor Nelson Edmondson suggests a teaching procedure in which humanities teachers would treat the various mythologies, philosophies, and theologies as "hypotheses of equal status". After describing this approach and considering his conceptions on the nature of hypotheses and the meaning of equal status, author examines the proper…

Previous studies have indicated that explaining a hypothetical event makes the event seem more likely through the creation of causal connections. However, such effects could arise through the use of the availability heuristic; that is, subjective likelihood is increased by an event becoming easier to "imagine". Two experiments were designed to…

Tests the hypothesis that a marathon gestalt workshop would foster positive changes of personal adequacy, attitudes toward social behavior, and attitudinal qualities related to improved learning efficiency and academic achievement. Uses the California Psychological Inventory to determine any personal growth. (Author/RK)

This paper presents an analysis of public opinion survey data including ethnic group membership, socioeconomic status, and preferences for public expenditures in 10 cities. (Author)

A visual-spatial approach to the study of attention dysfunction was presented. The hypotheses of broadened and narrowed attention were tested by comparing peripheral visual discrimination of acute schizophrenic, chronic schizophrenic, and normal subjects within two regions of the functional visual field.

This study was designed to test two sets of hypotheses derived from cognitive-behavioral theories of depression. Discusses the implications of the results for cognitive and behavioral theories of depression. (Editor/RK)

These experiments consider similarities and differences between classifications of pictorial and verbal stimuli in order to investigate whether the kinds of information used differ depending on the stimulus class. Three hypotheses regarding the information used in picture and word classification were evaluated. (Author/RK)

The intent of this study was to determine whether the Minnesota Percepto-Diagnostic Test (Fuller, 1969; Fuller & Laird, 1963) is more effective than the Bender-Gestalt (Bender, 1937) with respect to identifying achievement-related errors in visual-motor perception. (Author/RK)

Hospitalized brain-damaged patients were Ss in a study designed to evaluate the effectiveness of a treatment technique used with contingent reinforcement to facilitate acquisition and retention of environmentally relevant information. (Editor)

Answers to theoretical questions about the place of input in a formal second language acquisition model are dependent on a distinction between two kinds of learner hypotheses. Type-N hypotheses require "negative evidence" for testing, while Type-P hypotheses are tested on the basis of "positive data" alone. (Author/CB)

Eighty-one university students were given a battery of reaction time tests and a group test of intelligence which yielded timed and untimed scores. Multiple regression analyses indicated that speed of information-processing was an equally good predictor of timed and untimed intelligence test performance. (Author/LMO)

Argues that R. Trapp's reservations regarding the characterization of Jackson's and Jacobs' conversational argument are unfounded. Reports several studies that use procedures similar to those employed by Trapp to confirm Jackson's and Jacobs' theory. Discusses reservations about using subject generated judgments as an unproblematic standard for…
