Several sets of evidence are offered to support the hypothesis that cognitive and social development are intimately interrelated, and that mother-infant interaction influences both. A mother's prompt responsiveness to her baby's signals tends to foster the development of varied and clear modes of communication and thus the development of one facet…

Summary descriptions of the samples of teachers who participated in different project activities are given. In addition, descriptions of reporters of incidents in each student behavior category are outlined. (See TM 001 375 for project description.) (MS)

The power of the classical Linear Discriminant Function (LDF) is compared, using Monte Carlo techniques with five other procedures for classifying observations from certain non-normal distributions. The alternative procedures considered are the Quadratic Discriminant Function, a Nearest Neighbor Procedure with Probability Blocks, and three density…

In order to test the hypothesis that size of place of residence and urban proximity preferences constitute factors in population dispersal migration behavior, a random sample of 777 Pennsylvania households plus a sample screened for moving probability (N=319) were surveyed via personal interviews in 1974. A follow-up survey on actual migration…

Examines the impact that social position has on the attainment values which parents hold for their children. Research is based on the question of the relationship between parents' social status or social class and parents' aspirations and expectations for their children. ( Author/RK)

Textbook calculations of statistical power or sample size follow from formulas that assume that the variables under consideration are measured without error. However, in the real world of behavioral research, errors of measurement cannot be neglected. The determination of sample size is discussed, and an example illustrates blocking strategy.…

Examines changes in the liberalism-conservatism of college students and their non-college peers. Concludes that college students do not become more liberal than the control group of non-college cohorts. (Editor/RK)

This article highlights three common problems with assessment research, including the following needs: (1) to adopt a hypothesis testing approach; (2) for research to be guided by available formal and informal theory, and (3) for research to be consistent with general school psychological practice. New research methodologies and new research…

Two models of library circulation, the Markov model and the mixed Poisson Model, are applied to circulation statistics from the University of Saskatchewan. Goodness-of-fit tests indicate that neither model fits the data; in both cases, the set of noncirculating items is larger than that predicted by the model. (Author/LRW)

An article was published in the December 1985 issue of this journal that used LISREL to investigate the relationship between family medicine residents' moral reasoning and their clinical performance (Sheehan). The data from that study are reanalyzed to illustrate the importance of considering alternative structural equation models in evaluation…

Enumerates results of a study which asked graduate students and doctoral candidates to read in diverse content areas and to select main idea statements for text. Concludes that readers often made initial hypotheses about the main idea and used the main idea construction processes of listing, draft and revise, and topic/comment after the text had…

Analyzes the comments and behavior of one student during an interpretive reading discussion to show that this student proceeds in a cycle of learning. Reviews research in problem solving and reading comprehension to show that, for this student, reading comprehension is problem solving. (FL)

Three frequently used response formats are compared via analysis of covariance structures. The cumulative results based on four data sets provided evidence inconsistent with previous research suggesting that these formats are interchangeable. The semantic-differential format is most preferred while in most cases the Stapel format is least…

This article examines a current, explicit, central theory accounting for the observed flexibility in motor performance: the generalized motor program with a multiplicative rate parameter. Reanalysis of data reported in the literature and a study of skilled typewriting show that a generalized motor program generally does not fit observed…

It was hypothesized that adolescent females experience greater sex role strain than other kibbutz members. Loevinger's ego development test was administered to 40 kibbutz members. The findings supported the hypothesis and showed that adult women are significantly more likely to focus their dissatisfaction in the area of actual role behavior. (JAZ)
