The study investigates empirical properties of reasoning speed which is conceived as the fluency of solving reasoning problems. Responses and response times in reasoning tasks are modeled jointly to clarify the covariance structure of reasoning speed and reasoning ability. To determine underlying abilities, the predictive validities of two…

The results of the 2006 PISA (Program for International Student Assessment) study of reading comprehension, mathematical ability, and science understanding administered to 15 year olds in 56 countries [OECD (2007). PISA 2006: Science Competencies for Tomorrow's World. Paris: OECD.] are examined to assess the predictive validity of the national IQs…

This research examined whether the SAT and ACT would predict college grade point average (GPA) after removing g from the tests. SAT and ACT scores and freshman GPAs were obtained from a university sample (N=161) and the 1997 National Longitudinal Study of Youth (N=8984). Structural equation modeling was used to examine relationships among g, GPA,…

This study investigated whether measures of habituation and dishabituation in early infancy predicted later intelligence. Results were compared with those from other comparable studies. It was argued that the psychometric acceptability of infant cognitive measures needs to be demonstrated before they can be considered to be potential predictors.…

An historical overview of inductive logic is presented, including the logic of enumerative induction in its rule-derivative and event-predictive forms. An experimental test model of event-predictive induction in the linguistic medium is discussed along with its theoretical significance for future psychometric investigations. (Author/CM)

Assessed the predictive validity of the Emotional Accuracy Research Scale (EARS) (J. Mayer and G. Geher, 1996), a performance measure of emotional intelligence, with 40 undergraduate students. Results support the predictive validity of the EARS as a measure of emotional intelligence. (SLD)

Statistically significant correlations of .37 and .57 were obtained between infant recognition memory scores obtained at four to seven months and later vocabulary tests of intelligence, for 54 children tested at four and for 39 children seen at seven years, respectively. Obtained values did not vary by sex. (Author/RD)

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.…

Children (n=36), originally tested for visual novelty preferences at age seven months and intelligence estimates at age three, were tested for intellectual functioning and for visual recognition performance at age five. Results indicate that novelty preferences were more highly related to later intelligence quotients than to later recognition…

Zajonc and Bargh's (EJ 241 537) application of the confluence model to six national data sets is critiqued. Extreme differences in intelligence levels are predicted between nations, including substantial retardation for some populations. Moreover, the parameter values used do not allow mental growth functions which are consistent with previous…

This study evaluated the diagnostic validity of a task measuring abstract categorization ability in learning disabled (LD) and non-LD children. Data showed that the component of abstract category knowledge that best disciminates LD children from non-LD, is the knowledge of how members of abstract categories differ from each other. (Author/JAZ)

The effectiveness of a measure of the processing capacity of working memory, called the reading span test, is demonstrated in predicting performance and understanding individual differences in reading comprehension. (Author/PN)

Interrelationships among IQ, academic achievement, and teacher ratings of pupils' classroom achievement were evaluated in a large sample of children from various racial and socioeconomic backgrounds. A substantial relationship between standardized measures of IQ and achievement was found and was independent of race, but decreased with increasing…

This study examines cultural bias in the Wechsler Intelligence Scale for Children. Results indicated no evidence of specific factors peculiar to Blacks v Whites, and rank order of item difficulties was similar in both groups. Race differences were due to differences in mental maturity rather than to test bias. (Author/RD)
