It has often been claimed that children's mathematical understanding is based on their ability to reason logically, but there is no good evidence for this causal link. We tested the causal hypothesis about logic and mathematical development in two related studies. In a longitudinal study, we showed that (a) 6-year-old children's logical abilities…

Two groups of male adolescents, incarcerated young offenders (N = 64, mean age = 16.3 years) and a comparison group of community youth (N = 60; mean age = 16.6 years), were administered the Empathy Continuum (measuring cognitive-affective responses to persons in emotionally evocative videotaped vignettes) and questionnaire measures of empathy,…

This study describes a longitudinal design (following subjects described in Rutherford & Rogers [2003, "Journal of Autism and Developmental Disorder", 33, 289-302]) to test for predictors of pretend play competence in a group of children with autism. We tested the hypothesis that developmental change in pretend play performance can be predicted by…

This article reports the findings from a study that investigates predictors of police willingness to blow the whistle and police frequency of blowing the whistle on seven forms of misconduct. It specifically investigates the capacity of nine policy and structural variables to predict whistle-blowing. The results indicate that two variables, a…

Objective: The main aim of this study was to examine the age-dependent remission from ADHD in girls transitioning through childhood into adolescence and early adulthood. Method: We conducted a 5-year prospective follow-up study of 123 girls with ADHD and 106 non-ADHD control girls aged between 6 and 17 years at ascertainment. ADHD was considered…

The extent to which standardized regression coefficients (beta values) can be used to determine the importance of a variable in an equation was explored. The beta value and the part correlation coefficient--also called the semi-partial correlation coefficient and reported in squared form as the incremental "r squared"--were compared for…

Explores the differences among the traditional single-equation prediction model of test bias, the Cleary and the Thorndike model in a situation involving typical educational variables with young female and male children. (Author/DEP)

Proportional samples of 113 residents (68 successes and 45 failures) were randomly selected from 1,361 residents (838 successes and 523 failures) who entered state community corrections centers in Michigan. Cross-validated multiple regression analyses show employment status at the centers to be the most powerful predictor of success. (Author)

Developed two scales to examine the relationship between personality and performance of residential child care workers. The first scale differentiated child care workers from the general population, the second "most effective" from "least effective" child care worker incumbents. Personality characteristics proved to be better…

A study examined differences in motivations between fundamental Christians and atheists on the Reiss Profile of Fundamental Goals and Motivational Sensitivities. Only five of the 15 areas measured by the Reiss Profile were used in the study. The hypothesis was that (within these areas: (1) independence, (2) power, (3) vengeance, (4) status, and…

Using data on 682 couples from a national probability sample, demonstrated that a wife's perception of her husband's attitude toward her employment is moderately inconsistent with the husband's actual attitude. Found several couple characteristics significantly affect the level of inconsistency, indicating degree of couple communication. (Author)

Compares the uses of multiple regression, the Automatic Interaction Detector (AID) multivariate program, and cross-tabular analysis in identifying variables associated with newspaper readership. (RL)

Smokers and nonsmokers were exposed to anti-smoking communications to compare the relationship of emotional arousal, attitudes, and subjective normative beliefs. Findings revealed that smoking-related intentions were more strongly associated with attitudes toward smoking than with subjective normative beliefs or emotional arousal. (RC)

This article compares the standard structural categories of colleges with the "image factors" of the inventory of college activities as predictors of student orientations. The results are that it is difficult to obtain orthogonal "image factors" and, therefore, these factors cannot easily be used in regression equations.…
