The present study examined the moderating effects of intellectual functioning and ASD symptom severity on the relation between age and adaptive functioning in 220 youth with autism spectrum disorder (ASD). Regression analysis indicated that intellectual functioning and ASD symptom severity moderated the relation between age and adaptive…

Numerous studies indicate that intrinsic motivation predicts academic achievement. However, relatively few have examined various subtypes of intrinsic motivation that predict overall achievement, such as motivation for exercise and physical activity. Based upon the 16 basic desires theory of personality, the current study examined the motives of…

Distributed brain areas support intellectual abilities in adults. How structural maturation of these areas in childhood enables development of intelligence is not established. Neuroimaging can be used to monitor brain development, but studies to date have typically considered single imaging modalities. To explore the impact of structural brain…

Aims: Our aim was to examine intellectual development in children with congenital hemiplegia from early childhood to adolescence. Method: Full-scale IQ (FIQ), Verbal IQ (VIQ), and Performance IQ (PIQ) scores were measured in 32 participants (19 males, 13 females) with congenital hemiplegia at mean ages of 4 years 6 months (SD 7mo; 31…

A recognition memory experiment with 8-, 11- and 20-year-olds investigated the hypothesis that, with age, semantic encoding becomes increasingly important relative to acoustic encoding. (CM)

The Snijders-Oomen Nonverbal Intelligence Test (SON) was administered to 251 deaf children (6-15 years old) and 101 hearing children (10-12 years old) in Israel. The SON was judged appropriate for measuring cognitive functioning in the deaf because it requires no verbal instructions or responses and includes a measure of abstract thinking ability.…

This study investigates age differences in children's semantic expectations regarding causal relations in stories about three realistic goal situations (being friendly, getting a dog, and doing chores). Twenty children at each of three age levels (ages 6, 9, and 12) were asked to produce stories and answer probe questions about wanting and not…

Investigated beliefs about intellectual control and aging in 86 middle-aged and older adults. Perceptions of internal control over intellectual functioning appeared to be relatively stable during middle adulthood and to decline for older adults. Even with effects of education partialled, there was a decline in perceptions of intellectual…

Miscue analysis patterns of second, fourth, and sixth grade students of high and low reading ability show that miscues acceptable in context increase by grade level and ability. (CJ)

The relationship between higher order reasoning and sex bias was investigated among children 7, 9 and 11 years old. Children read arguments enhancing their own or other gender, then rated argument intelligence, judged other children based on observations, and justified their arguments. Findings showed that own-gender reasoning biases declined with…

This study examines the longitudinal relationships between mastery motivation and differentiated measures of intellectual development assessed at 1 and 3 1/2 years of age in a sample of 35 children (21 boys and 14 girls). At one year three types of mastery motivation were assessed using structured tasks: (1) producing effects (engaging in…

Using a sample of 158 low-income black women and their infants, this study examined the relation between mother's age and measures of maternal behavior reflecting verbal responsivity, punitiveness, and instrumental support for intellectual development. (Author/NH)

Data on the concurrent validity of the McCarthy Scales, using two Wechsler Scales for Children as criteria, were compared with those of previous studies. Significant moderate to strong correlations at preschool and school-age levels between the General Cognitive Index of the McCarthy and Wechsler IQ's were noted. (Author/RD)

This study examines developmental differences in third and sixth graders' and college students' use of distinctiveness, consensus, and consistency information for making causal attributions. (CM)

Examined bias in reasoning in adults and in children, ages five through nine years, by presenting story or videotape true/false messages. Found that adults made judgments contaminated by their own background knowledge abut the believability of the message more frequently than did children. (ET)
