Forty adolescents with reading/spelling disabilities were assigned on the basis of IQ/achievement discrepancy scores to either a dyslexic or slow learner group. Significantly more females than males were in the slow learner category. Despite having lower IQs, the slow learning group had higher achievement levels, but group differences on…

IQ is not found to be an important variable in explaining delinquent behavior among juveniles. In contrast, structural variables, e.g., access to desirable social roles, positive labeling of the school, are well supported as influences on delinquency. (RM)

To investigate the factors determining why some children succeed at certain intellectual tasks while others of equal or near equal IQ, age, and motivation are unable to master the same task, 145 female and 144 male eighth grade students were administered "An Inventory of Piaget's Developmental Tasks" (IPDT). Labeled as concrete,…

Using data from a broader longitudinal study, this investigation explores within-subject and cross-generational stability of intellectual competence and the relationship of such stability to aggressive behavior. Data were gathered three times (when subjects' modal age was 8, 19, and 30 years). Initially, subjects included the entire population…

Replicates and extends to older adolescents previous findings of factorial independence between IQ and daydreaming in both gifted and average children and young adolescents. Also aims to relate to the development of moral reasoning ability research findings of a decline in guilt and fear-of-failure daydreams among children, adolescents, and…

A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were: experience; age; locus of control; field dependence-independence (FID); rigidity/flexibility; intelligence quotient (IQ); and sex. Causal relationships…

To examine the validity of short forms of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the WISC-R was first administered to 106 hospitalized psychiatric patients, aged 8-16. No subjects had a primary diagnosis of mental retardation or learning disability, and one-third were receiving psychotropic medication. WISC-R IQ scores…

Reports data on several measures for 160 low income black ninth- and tenth-graders who participated for one year in Bereiter-Engelmann, DARCEE, Montessori, or traditional prekindergarten. Discusses possible relationships between techniques used in different preschool programs and sex differences in achievement level and IQ. (Author/CB)

An empirical analysis of the relationship between science reasoning skills and the amount of information acquired during science learning as predicted by a neuromathematical model of information processing is presented. Subjects were 93 adolescents (mean age of 15.4 years old) with a IQ range of 91-142. (Author/JN)

This study examined the effectiveness of a social skills training program for five male adolescents with autism but normal IQ. In addition to teaching interactional and conversational skills, the program provided explicit instruction in social-cognitive principles of inferring the mental states of others. Significant changes in beliefs were found,…

Eighty children, ages 3 to 17, with autism or Asperger's syndrome and mild to severe distress in the presence of some sounds received either auditory training or a control condition of listening to the same music. Significant improvements in behavior, severity of autism, and IQ were achieved and maintained for 12 months by both groups. (Author/DB)

This study compared working memory in 28 high-functioning autistic individuals (ages 7-18) with that of 30 individuals with Tourette Syndrome or typically developing. No group differences were found. Performance was significantly correlated only with age and IQ. Results suggest that working memory is not an executive function seriously impaired in…

Comparison of children and adolescents with Fragile X Syndrome (n=18) or autism (n=18) for changes in cognitive ability and adaptive behavior over 9 years found steeper decreases in IQ scores among Fragile X subjects with older autistic subjects autism exhibiting stable test-retest scores. Comparative declines in adaptive behavior scores were…

Although the media has attended to the subject of juvenile homicide, the professional literature on the subject is sparse. To identify a model for standardized data collection for juveniles who murder, 12 juveniles charged with first degree murder were administered a series of tests during psychological interviews. Data were collected on social…
