A growing controversy surrounds the strict interpretation of statistical significance tests in social research. Statistical significance tests fail in particular to provide estimates for the stability of research results. Methods that do provide such estimates are known as invariance or cross-validation procedures. Invariance analysis is largely…

This paper discusses the principles underlying discriminant analysis and constructs a simulated data set to illustrate its methods. Discriminant analysis is a multivariate technique for identifying the best combination of variables to maximally discriminate between groups. Discriminant functions are established on existing groups and used to…

Multivariate methods were used to identify between-set factors relating the criterion set of eleven Wechsler Adult Intelligence Scale Revised subtest variables to the predictor set of demographic variables: age, race, sex, education, occupation, geographic region, and urban versus rural residence. Although factor analysis is usually used to…

Studied the influence of intelligence, self-concept, and causal attributions on metamemory and the metamemory-memory behavior relationship in elementary school children. Results indicated that intelligence had an impact on metamemory in all age groups; and that metamemory remains an important predictor of memory behavior. (Author/RWB)

Factor analysis of coping behavior in adolescents in Frankfurt, Germany, and Tel Aviv yielded similar structures, but Israelis demonstrated a marked preference for internal coping strategies as opposed to coping by means of social resources. Discusses the impact of environmental and historical conditions. (DM)

Researchers on the Lasting Benefits Study (LBS) are tracking students who participated in Tennessee's K-3 Student/Teacher Achievement Ratio (STAR) Project (1985-89) as they continue into later grades. Project STAR was a statewide experiment conducted to demonstrate the effects of reduced student/teacher ratios (15:1) on student achievement…

To test the theory of mental calibration for mental addition it was hypothesized that the mean reaction time for problems in homogeneous sets will be faster than for problems in heterogeneous sets and that the reaction time was inversely related to ability and development (grade level) and independent of gender. Three sets of 40 addition problems…

The purpose of the study was to determine if captions displayed on instructional video programs interfere with learning in hearing audiences. Eighty hearing undergraduate students enrolled in lower division education classes were randomly assigned to one of two groups. Each subject completed a questionnaire to collect self-report data on sex, age,…

This study examines differences in attitudes and anxiety levels toward computers between a group of black high school teachers who had regular exposure to computers (Group II) and a group of who had little or no exposure (Group I). Forty teachers from several Mississippi Delta high schools responded to a questionnaire containing demographic and…

A total of 1,487 eleventh grade students from the Hamburg (West Germany) school system were asked to complete four writing assignments used in an International Association for the Evaluation of Educational Achievement (IEA) study of writing assessment. In analyzing the writing samples, the study focused on: (1) between-rater effects; (2)…

Application of computer technology to psychiatric outcome measurement offers the promise of coping with increasing demands for extensive patient interviews repeated longitudinally. Described is the development of a cost-effective multi-dimensional tracking device to monitor psychiatric functioning, building on a previous local computer interview…

Examines census data on the fertility of U.S. immigrants to study trends in fertility after migration. Results show that immigrant fertility may rise after arrival in the new country, perhaps because immigrants are making up for births or marriages postponed because of the move, but that, with assimilation, fertility declines. (AF)

Compares the effect of weak, flexible, and rigid family structures on the cognitive development of 61 Scottish and 40 Pakistani school children in Glasgow, Scotland. In a problem-solving test, children from flexible environments outperformed those from either weakly or rigidly structured homes. This difference was reflected in the school…

In a replication of Mills's study of sex differences in self-posing behavior (1984), 1,659 female and 1,760 male undergraduate students from art schools and science schools at the University of Sussex were photographed. Arts students of both sexes displayed stereotypically female nonverbal behavior, suggesting field of study as a more reliable…

In a study examining attachments to celebrity figures, 79 male and female fifth, eighth, and eleventh graders and college sophomores described themselves and their favorite celebrities. It was found that such attachments are equally important to males and females, and that gender and age affect the nature of the attachment. (DM)
