Discusses the reasons for the rise in IQ scores over time. Demonstrates the effect of the decrease in age at levels of schooling on the rise in IQ scores utilizing the data from the 1936 and 1968 standardization of the Otis Intermediate Test of Mental Ability, Form A, in New Zealand. (CMK)

Compared four groups of men from a Danish birth cohort: those at high risk for serious criminal involvement (with severely criminal fathers) who avoided and who evidenced serious criminal behavior, and those at low risk (with noncriminal fathers) who evidenced or did not evidence criminal behavior. Found the mean intelligence quotient score of the…

Compared the Matching Familiar Figures Test performances of 53 children in grades five and six, identified as being depressed, to performances of 53 nondepressed children. The depressed group had longer latencies, made more errors, and was less efficient, even when intellectual differences were taken into account. (Author)

Children, below- and above-average intelligence, were administered tasks involving matching information between auditory/visual modalities and temporal/spatial presentations. The below-average group made more errors and matching problems were not particular to one modality. Factor analyses did suggest that matching processes varied with level of…

Inspection time (IT) and Peabody Picture Vocabulary Test (PPVT) scores from 75 school children aged 6-13 years in 2001 were compared with the performances of 70 children aged 6-13 years who had attended the same primary school in 1981 ["J. Exp. Child Psychol." 40 (1985) 1.]. ITs for the 2001 sample were measured with the same four-field…

The extent to which schooling brings about change in the rank order of students along the hierarchies of intelligence is a pervasive sociological concern. Until quite recently the emerging consensus was that schooling is relatively ineffective in this regard and that intelligence is largely exogenous to the educational process. A study to…

The expert-novice paradigm, which demonstrates the outstanding role of domain-specific knowledge in explaining differences in memory behavior and performance, was examined. Two studies are described which compared memory performance of groups equivalent with regard to domain-specific knowledge but differing in intellectual ability. The hypothesis…

Differences were investigated in performance between third-grade American and Canadian children on two subtests of the Wechsler Intelligence Scale for Children Revised. Results were discussed in terms of Canadian and American curriculum contents and test-taking experiences. (Author/JKS)

Six Hong Kong preschoolers with Down syndrome who attended a center-based educational intervention program were assessed and matched on age, mental age (MA), and IQ. Three of the preschoolers also attended regular preschools two days per week. After a year, the children who also had attended regular preschool had higher MA and IQ. (Author/CR)

A study examined the impact of a gifted enrichment program on 80 Israeli students (grades 4-8) from disadvantaged neighborhoods. After program participation, girls' performance on an intelligence test was higher than boys'. While girls started out with slightly lower scores, they ended up with slightly higher scores than boys. (Contains…

Change in cognitive functioning is an important aspect of human aging and a key outcome in many medical conditions. However, cognitive change can rarely be measured directly, since prior cognitive data do not exist for most people. We examined the criterion validity and one-year stability of the difference between National Adult Reading Test…

The pattern of honors degrees awarded in British universities in 1967, 1978, and 1979 shows women receiving lower percentages of both top and weakest honors degrees. Various explanations are considered, and it is concluded that the answer is in the differences in distribution of ability measured by intelligence tests. (MSE)

A study explored working memory (WM) capacity, WM task requirements, as well as effects between WM, skills, knowledge base, and intelligence in adults with mental retardation and children aged 3-6 years. Adults were better on measures reflecting skills and knowledge base. Children performed better in phonological and visuo-spatial WM tasks.…

The research studies the quality of life (QOL) of 127 men and women diagnosed as having a borderline IQ and ADHD living in two major residential programs of the Sharon region in central Israel in respect to their personal, disability, and social ecological variables. Core findings indicate that men and women differ significantly according to their…

Urban and rural Aboriginal- and Anglo-Australian children were tested for reading and math achievement, for nonverbal psychometric test intelligence, and for three cognitive styles. Psychometric intelligence was clearly a more powerful predictor of the effects of culture and location on school achievement than was cognitive style. (Author/CMG)
