On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the…

Evidence is reviewed pointing to a negative relationship between intelligence and religious belief in the United States and Europe. It is shown that intelligence measured as psychometric "g" is negatively related to religious belief. We also examine whether this negative relationship between intelligence and religious belief is present between…

The Mayer, Salovey, & Caruso Emotional Intelligence Test (MSCEIT) has been reported to provide reliable scores for the four-branch ability model of emotional intelligence [Mayer, J. D., Salovey, P., & Caruso, D. R. (2002). "Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). User's manual." Toronto, Canada: Multi-Health…

Receptive foreign language proficiency is usually measured with reading and listening comprehension tasks. A novel approach to assess such proficiencies--viewing comprehension--is based on the presentation of short instructional videos followed by one or more comprehension questions concerning the preceding video stimulus. In order to evaluate a…

This 5-year prospective longitudinal study of 70,000+ English children examined the association between psychometric intelligence at age 11 years and educational achievement in national examinations in 25 academic subjects at age 16. The correlation between a latent intelligence trait (Spearman's "g"from CAT2E) and a latent trait of…

Confirmatory factor analysis was used to test models of the relationship between inspection time (IT) and psychometric measures of intelligence in a sample of 134 healthy adults in the United Kingdom. A nested structural equation modeling approach shows that IT is most strongly associated with the Perceptual-Organizational factor of the Wechsler…

Studied the role of olfactory processes within the theory of fluid and crystallized intelligence by testing 107 Australian college students with a battery of psychometric and olfactory tests. Results indicate the likely existence of an olfactory memory ability that is structurally independent of established higher-order abilities and not related…

Using multi-group covariance and means structure analysis (MG-CMSA), this study investigated whether sex differences were present on the Dutch WAIS-III, and if so, whether these sex differences were attributable to differences in general intelligence ("g"). The sample consisted of 294 females and 228 males between 18 and 46 years old.…

Administered 2 elementary cognitive task (ECT) tests and 2 psychometric intelligence tests to 169 monozygotic and 131 dizygotic pairs of twins in Germany. Reaction times correlated negatively with psychometric intelligence, and habitability estimates were substantial for both psychometric intelligence and reaction times on the ECTs. Multivariate…

Timed performance measures from a coincidence timing task taking about 10 minutes are shown to have significant correlations with psychometric general intelligence in a group of 56 children. The mean absolute error across three conditions correlated -.294 with Raven's Standard Progressive Matrices scores but was sex-biased, with girls being less…

To establish the relationship between categorization ability and psychometric intelligence, 98 ninth graders in Israel were instructed to group 28 common Hebrew nouns into categories and were given a battery of intelligence tests. Results are discussed in terms of their impact on the design of intelligence testing. (SLD)

The relationship between general intelligence and the ability to ignore irrelevant stimuli appearing in the same visual field as an attended target was studied for 167 college students. Results indicate that psychometric intelligence does not tap visual focused attention. (SLD)

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)

A large sample of 11-year-olds were observed on a perceptual maze task. Three ability level groups were formed and compared as to overall response paths and specific binary decision configurations. Explanations for observed qualitative differences and discussion of the viability of the experimental approach adopted are presented. (Author/RD)

The hypothesis that a task that increases in complexity (increasing its correlation with a central measure of intelligence) does so by increasing its dimensionality by tapping individual differences or another variable was supported by findings from 46 adults aged 20-70 years performing a mental counting task.
