Racial and social class factors as a determinant of school achievement for minority group children are discussed with reference to the many empirical studies in this area. (Author/AM)

Notes that preschool compensatory education has not resulted in any appreciable, durable gains in I.Q. or scholastic achievement. Posits that compensatory programs remedied deficiencies in knowledge but not in cognitive processes. Suggests further research into the nature of intelligence and its malleability. (PGD)

The hypothesis that racial differences in IQ stem from differences in components of executive systems including knowledge base, control processes, and metacognition was investigated. Group differences in metamemory, strategy use, and general knowledge, but not perceptual efficiency, were observed. Metamemory predicted crystallized but not fluid…

Explores the generality of findings relating intelligence to Inspection Time (IT), the exposure necessary to judge which of two lines is longer, in two studies using normal children and mentally retarded adults. Results showed the relationship between IT and performance IQ was lower in the mentally retarded group. (JAC)

Children aged 6 to 13 years were given verbal and nonverbal fluency tasks and block design subtests of the Wechsler Intelligence Scale for Children-Revised. Results, providing normative data, showed that fluency tasks are age-, but not sex-dependent, and are modestly correlated to one another. (Author/CM)

The predictive power of various cognitive skills at three months of age in terms of later cognitive functioning was examined. Visual habituation and recovery predicted later intellectual functioning at 24 months better than global intelligence or object permanence scores. Changes in cognitive functioning may be a transformation of skills.…

The performance of 136 college students at the University of Western Ontario (Canada) on various parameters of two well-known puzzles was compared with performance on a measure of general intelligence and the Hidden Figures Test. An interpretation of the results is provided by Sternberg's experimental subtheory of intelligence. (SLD)

Three studies involving 16 college students explored cognitive processes reflected by reaction time (RT) and movement time (MT). The hypothesis that correlations of RT and MT with measures of intelligence are due to effects on a common stage of information processing cannot be rejected on the basis of study findings. (SLD)

This commentary on a paper by Douglas Detterman and others (EC 604 995), which tested a model assessing basic cognitive abilities in young adults with and without mental retardation, criticizes the paper for drawing conclusions not justified by the empirical results. (JDD)

Proposes that educational researchers consider the implications of a new psychological concept, dysrationalia: the inability to think and behave rationally despite adequate intelligence. The paper argues that researchers need an intuition pump, or prompt, like dysrationalia to aid in reconceptualizing intelligence because I.Q. tests do not measure…

Eight tactile-kinesthetic indices and 27 cognitive-ability and mental-speed measures were administered to 195 college students and community members. Results suggest that tactile-kinesthetic abilities share much with broad visualization and fluid intelligence, little with crystallized intelligence, and differential relationships with speed related…

Results are reported of an analysis of Wechsler IQ scores of 37 children (ages 3-14) with Asperger syndrome. Data revealed cognitive patterns dissimilar to those of children with other autism related disorders and similar to many typically developing and achieving individuals.. Findings are discussed in reference to identification and intervention…

The relationship between brain size and intelligence was examined in 90 normal volunteers. Results support the notion of a modest relationship between brain size and measures of global intelligence and suggest diffuse brain involvement on performance tasks that require integration and use of multiple cognitive domains. (Author/SLD)

Comments on the other papers in this theme issue and presents a speculative account of inspection time (IT). IT is viewed as an index of core information-processing ability that has a causal influence on the development of complex intellectual skills. (Author/SLD)

Examined the relationships between the latencies of theoretically corresponding and noncorresponding component processes across diverse tasks derived from the structure of intellect model. Results for 72 participants provide evidence that corresponding component processes are generalizable while noncorresponding component processes are not. (SLD)
