Three groups of 18 children were selected for this study, one group with autism spectrum disorders (ASD), one group with developmental delays in which ASD was ruled out (DD), and one group with typical development (TD), from a pool of 3026 children who were screened with the Communication and Symbolic Behavior Scales Developmental Profile (CSBS…

Adolescents with substance use and conduct disorders have high rates of aggression and attention deficit hyperactivity disorder (ADHD), all of which have been characterized in part by impulsivity. Developing measures that capture impulsivity behaviorally and correlate with self-reported impulsivity has been difficult. One promising behavioral…

Using both proficiency tests and self-assessment measures, this study investigated (a) whether 3 subgroups of Japanese heritage language (JHL) learners would demonstrate language behaviors distinctively different from those of traditional Japanese as a foreign language (JFL) learners, and (b) which domains of language use and skills would…

The authors performed 5-year prospective follow-up (retention rate = 92%) with an ethnically diverse sample of girls, aged 11-18 years, who had been diagnosed in childhood with attention-deficit/ hyperactivity disorder (ADHD; N = 140) and a matched comparison group (N = 88). Hyperactive-impulsive symptoms were more likely to abate than…

We identified 201 individuals who obtained IQs of 85 or below in high school and participated in the Wisconsin Longitudinal Study (a prospective longitudinal study that followed sample members from age 18 through age 53). Their life course development was contrasted with their siblings who obtained IQs above 100. Life course outcomes were assessed…

Aggression in a proportion of people with intellectual disabilities is often assumed to be due to social-cognitive deficits. We reported on two studies in which we compared the emotion recognition and perspective-taking abilities of 43 frequently aggressive individuals and 46 nonaggressive peers. No difference was found between the groups' ability…

This study examined differences between 326 students enrolled in a full-day kindergarten program and 311 students in a half-day program. Data were obtained from six measures of academic achievement from the California Achievement Tests, administered in the spring. Results indicated no significant differences between the two groups on four measures…

Forty-eight textbooks in educational psychology published after 1950 were located for review. Half the books were published before 1975 and half following 1975. The purpose of the study was to describe changes in coverage and treatment of individual differences and special populations since the passage of Public Law 94-142 (the Education for All…

The roles of training, problem representation, and individual differences on performance of both automated (simple) and controlled (complex) process tasks were studied. The following hypotheses were tested: (1) training and cognitive style affect the representation developed; (2) training and cognitive style affect the development and performance…

The vocational interest patterns of young unwed mothers were investigated by comparing the scores of a sample of unwed mothers with percentile averages from a national norm group. The interest differences of mothers who gave up their babies and mothers who kept their babies were also examined. Subjects were 53 young unwed mothers enrolled in a…

The incorporation of computer-managed instruction into an academic program made it necessary to identify those cognitive styles, abilities, and aptitudes which were relevant to the success or failure of trainees in the Navy's Basic Electricity and Electronics (BE/E) School in order to minimize the attrition rate. Measures of 6 styles, 6 abilities,…

Used the Sibling Inventory of Differential Experience with 396 adolescent and young adult children to determine the extent to which genetic differences between siblings or sibling differences in family constellation variables were responsible for differential experiences. (HOD)

Discussed whether similarity affects the relationship between comparison and other-evaluation. Subjects read about an emergency, estimated their reaction, and evaluated a target who failed to help. Results showed increasing discrepancy between self and other's reactions led to more negative evaluations if self and target were the same sex.…

Identified persons who actively direct and influence the positive evolution of others by acting upon the environment. Selected individuals on the basis of service to the community and matched them with a comparison group. A comparative analysis indicated differences in education and personality characteristics in the selected "autoevolutionary"…

A novel cognitive style distinction is introduced: the Assimilator, who stretches established principles to meet novel tasks, and the Explorer, who seeks novel solutions even when established principles would serve. The assets and liabilities of each problem-solving style are considered and results of a validation study presented. (Editor/SJL)
