The authors argue that upon publication of a paper, the data should be made available through online archives or repositories. Reasons for not sharing data are discussed and contrasted with advantages of sharing, which include abiding by the scientific principle of openness, keeping the data for posterity, increasing one's impact, facilitation of…

Inspection Time (IT) is a psychophysical speed measure that has been linked to a range of cognitive abilities with results finding that shorter IT is associated with superior performance in cognitive abilities. Following a recent suggestion by Nettelbeck and Wilson [Nettelbeck, T., & Wilson, C. (2004). The Flynn effect: Smarter not faster.…

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,…

The results of studies regarding intelligence in infancy are reviewed, and are compatible with Sternberg's findings on intelligence in adulthood. It is suggested that a major aspect of intelligence--attitude toward and performance with novel kinds of concepts--is continuous in nature throughout the life span, but requires different measurement…

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.…

The current study examines the views of experts in the science of mental abilities about the primacy and uniqueness of "g" and the social implications of ability testing, and compares their responses to the views of a group of non-expert psychologists. Results indicate expert consensus that "g" is an important, non-trivial determinant (or at least…

The present study evaluated the criterion validity of the aggregated tasks of basic cognitive processes (TBCP). In age groups from 6 to 19 of the Woodcock-Johnson III Cognitive Abilities and Achievement Tests normative sample, the aggregated TBCP, i.e., the processing speed and working memory clusters, correlate with measures of scholastic…

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.…

Studies reporting predictions from assessments of infant recognition memory to later developmental performance and IQ are critiqued. Inelegancies in design, procedure, and analyses are noted. While this approach may have potential, its utility for practical or clinical purposes is still not demonstrated. (Author/RD)

This article describes the formulation and execution of the Rainbow Project, Phase I, funded by the College Board. Past data suggest that the SAT is a good predictor of performance in college. But in terms of the amount of variance explained by the SAT, there is room for improvement, as there would be for virtually any single test battery. Phase I…

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…

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)
