Background: To assess the co-occurrence in deviant trajectories of parent-rated symptoms of conduct disorder (CD), oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) from age 4 to 18 years old in a general population sample of Dutch children. Methods: Developmental trajectories of CD, ODD, and ADHD were…

The effectiveness of the Self-Appraisal Questionnaire (SAQ) in providing estimates for predicting violent and nonviolent recidivism over a 9-year period is examined. The SAQ is a quantitative risk/need instrument consisting of 72 items that compose eight subscales. There were 657 federally sentenced Canadian male offenders who completed the SAQ…

Callous and unemotional (CU) traits have been linked to severe antisocial behavior in youth, but studies examining the etiology of CU traits are lacking. Based on prior research, it was hypothesized that childhood anxiety and parenting practices would interact to predict changes in CU traits over time. Hypotheses were tested using a sample of 120…

A measurement scale should be short and quick to complete if it is to be practically useful. Drawing on data from a community-based survey of 2,178 people in Hong Kong, we compared five short forms (5- to 10-item) and the original version (20-item) of the Center for Epidemiologic Studies-Depression Scale (CES-D; Radloff, 1977) in predicting…

Using a continuous tracking task, the authors examined whether stopping is resistant to expectancies as well as whether it is a representative measure of response control. Participants controlled the speed of a moving marker by continuously adjusting their response force. Participants stopped their ongoing tracking in response to auditory signals…

Through the use of some purposeful anachronisms, Tom Stoppard uses his 1993 play "Arcadia" to explore the effects on man's psyche of the transition from Newton's Laws to the laws of thermodynamics and from thermodynamics to chaos theory. However, remarkably similar reactions to these changes are also reflected in works from the actual time periods…

Item-level statistics from ability and achievement tests have been underutilized as sources of data for building models of cognitive development. How item data can be used to build a cognitive-developmental map of proportional reasoning is demonstrated. The product of the analysis is a cognitive hierarchy with levels corresponding to categories of…

The all-possible subset approach is recommended as an alternative over stepwise methods for selecting the best set of predictor variables for multiple regression. Several criteria are available for selecting the best subset model. These are compared with the principal component regression (PCR) method to investigate their usefulness for subset…

To test the efficacy of variables found effective in regular classrooms (in previous process-product research), variables were observed for 126 elementary school children in 17 resource classrooms. Measurement of teacher structure and student achievement was performed. Results indicated that, although most of the variables were used to at least a…

Male patients complaining of impotence (N=32) were administered the Male Impotence Test (MIT) and the Minnesota Multiphasic Personality Inventory (MMPI). The results suggested that the MIT is without value for differentiating between psychogenic and biogenic impotence, whereas two rules from the MMPI appropriately classified 90 percent of the…

This article demonstrated that equations derived from Herrnstein's matching law can make quantitative predictions for many of the effects David Premack has studied on the relative nature of reinforcement. (Author/RK)

Concludes that time-consuming man-made counts of syllables can quite accurately be done by computers. (RB)

The study was designed to establish, on a regional basis, the validity of a set of measures of social handicap as predictive of educational backwardness and to identify the characteristics of those schools which are most compensatory in adverse social conditions. (Editor)

Replication was undertaken of a recent study conducted by Buell and Anthony which had found that recidivism and posthospital employment could be predicted by a single demographic variable, number of previous hospitalizations and employment history, respectively. Results of the replication were consistent for posthospital employment but not for…

The present study represents an attempt to enhance the self-concepts of juvenile delinquents, with the prediction that the juveniles' behavior would become more socially acceptable as a result of the self-concept change. Significant results were obtained on the post-test of the TSCS. (Author/PC)
