A study was conducted to determine why the theoretical relationship between dogmatism and conformity had not been verified in correlation studies. The study was designed to study the effect of differing statistical treatments on the coefficient of correlation. Data generated in an experimental framework included conformity scores and dogmatism…

Several procedures proposed in the literature for the analysis of growth curves are reviewed. Particular attention is given to the current issues in this area to guide practitioners in the selection of the most appropriate methodology. (Author)

When the variance assumptions of a repeated measures ANOVA are not met, the F distribution of the mean square ratio should be adjusted by the sample estimate of the Box correction factor. An alternative is proposed which is shown by Monte Carlo methods to be less biased for a moderately large factor. (RC)

The primary purpose of the study was to investigate and compare the critical thinking development in grade eight students in Saskatoon resulting from the traditional approach and the cognitive curriculum approach to the teaching of social studies. (Author)

The t ratio used in testing the difference between two independent regression coefficients is generalized to the multivariate case of testing the difference between two vectors of regression coefficients. This is particularly useful in determining which of two variables best predicts a number of criterion variables. (Author/JKS)

The problem of determining the significance level which should be used in statistical tests of item validity in order to minimize type I errors is discussed. (Author/JKS)

This research tested predictions derived from equitable exchange, social attraction, and normative information theories of self-disclosure. (Editor/RK)

The author compares the aggressiveness of individuals who had a nonaggressive alternative available with those who did not, and assesses the interaction of the presence or absence of the nonaggressive response alternative with the opponent's pattern of attack. Results are discussed in terms of attribution and locus of control. (Author/RK)

The relationships between educator's innovation adoption behavior and attributes of innovations described by Rogers and Shoemaker are examined. Only one of the five hypothesized relationships was accepted. (DS)

Tests Ausubel's (1960) subsumption theory of learning in the context of children's use of causal and logical connectives. Predicts that the acquisition of prior cognitive structure organizers would facilitate the learning and retention of subsequently presented concepts and logical operations and lead to a decrease of syncretic reasoning and…

The problem of comparing two sociometric matrices, as originally discussed by Katz and Powell in the early 1950's, is reconsidered and generalized using a different inference model. In particular, the proposed indices of conformity are justified by a regression argument similar to the one used by Somers. ( Author/JKS)

Two experiments are reported which compared different forms of presentation of a perspective-taking task. The task required 4-year-old children to select pictures showing another person's view of an array similar to Piaget and Inhelder's mountains. (Editor)

Grant and Roberts found that houselight presented throughout the delay period on a delayed matching-to-sample task caused pigeons to demonstrate a much lower level of accuracy than was found when the delay was spent in darkness. A series of experiments was carried out to examine possible mechanisms responsible for this light-induced retroactive…

After offering some critical observations, the author concedes that much of the most valuable work in the theory and the practice of psychotherapy has been done by the behavior therapists. (Author)

Academic achievement motivation in three types of male Jamaican high school students was compared. The three student types were based on certain combinations of high and low levels of the variables of intelligence, academic achievement, and social class. (Author/AM)
