The Relationship

The relationship between cognitive ability and laterality was examined in tetras of the relation of intelligence test scores to lateral preference. The factor analysis was performed on the variables of 12 tasks of the intelligence scale and total lateral preference. A slight relation was found between lateral preference and figure combination task. To clarify the relationship, the mean scores of tasks were tested for subjects who preferred the right and left on each preference item. Some significant differences were found. On some items, the mean scores of subjects with left preferences were inferior to those of subjects with right preferences on the figure-combination task. The result confirmed Levy's finding (1969). But cross-validation on a large sample is required.

Intelligence Test Scores

The effects of inbreeding in humans on the intelligence has been investigated in the present study of offsprings of second cousin matings (F= 0.0156, n=138 male, 132 female), first cousins once removed (F= 0.03125, n=148 male, 138 female), first cousins (F= 0.0625, n=161 male, 151 female), and unrelated (F= 0, n= 194 male, 182 female) among North Indian Muslims. The Weschler Intelligence Scale for Children (WISC-R)-74 was given to the children in the both groups. An overall significant (p<0.001) reduction of means has been observed in inbred series. The results of this study confirm the appreciable inbreeding depression especially among the offspring of first cousins. Asia Pac J Public Health 2004; 16(2): 99-103.

The Relationship

The present research examined further the relationship among measures of locus of control, intelligence, and academic achievement in adolescents. Intelligence test scores were significantly related to locus of control while no significant relationship existed between academic achievement and locus of control. The failure to find a significant relationship between academic achievement and locus of control in these adolescents raised questions about the previously claimed relationship of achievement and locus of control. That intelligence and locus of control were significantly related further supports the contention that locus of control is a function of intelligence rather than achievement.

Far more frequent than any other type of investigation relating to secondary school mathematics has been that which concerned itself with the relationship between scholastic success and other factors—intelligence test scores and their derivatives, I.Q. and M.A., and previous school marks being employed most frequently.

Reduced Risk

There is new empirical evidence that the effects of impending death on cognition have been miscalculated because of neglect of the incidence of dropout and of practice gains during longitudinal studies. When these are taken into consideration, amounts and rates of cognitive declines preceding death and dropout are seen to be almost identical, and participants aged 49 to 93 years who neither dropout nor die show little or no decline during a 20-year longitudinal study. Practice effects are theoretically informative. Positive gains are greater for young and more intelligent participants and at all levels of intelligence and durations of practice; declines in scores of 10% or more between successive quadrennial test sessions are risk factors for mortality. Higher baseline intelligence test scores are also associated with reduced risk of mortality, even when demographics and socioeconomic advantage have been taken into consideration.

This is the third of a series of papers dealing with the effects of repeated retesting on intelligence test scores. It comprises an account of two further experiments, and a discussion of the four so far performed, since each throws light on the results of the others and it is their joint interpretation which is thought to be of value. The two earlier experiments consisted in repeated testing of a group of W.E.A. students and a group of mentally defective boys by an intelligence test (AH 4) designed for an unselected population. In the two later experiments, a group of Technical College students and a group of Naval Ratings were repeatedly tested on another intelligence test (AH 5), designed for a population of high-grade intelligence, such as university students. Examination of all the results confirms the artificiality of the “ceiling effect” which was suspected in the first experiment; it suggests that, given sufficient scope, subjects of all levels of intelligence would, with repeated trials on the same test, continue to improve their score up to and beyond 10 testing; and that, given comparable opportunity, subjects with initially higher scores will tend to improve more than those with initially lower scores. All these results concern short-term experiments with testing at weekly intervals. The four sets of results considered jointly indicate that conclusions on these problems should be drawn only in terms of the relation between the level of the test and that of the group tested: this offers some resolution of the conflicting findings of earlier investigators.

The Military

To estimate the effect of neonatal hyperbilirubinemia on long-term cognitive ability in full-term newborns with a negative Coombs test, we performed a 17-year historical prospective study of 1948 subjects. Intelligence tests and medical examinations performed at the military draft board were stratified according to serum bilirubin concentration. A logistic regression analysis was used to adjust for the confounding effects of gestational age, birth weight, Apgar score, ethnic origin, socioeconomic class, paternal education, birth order, and the administration of phototherapy and exchange transfusion. No direct linear association was shown between neonatal bilirubin levels and intelligence test scores or school achievement at 17 years of age. However, the risk for low intelligence test scores (IQ score &lt;85) was found to be significantly higher (P = .014) among full-term male subjects with serum bilirubin levels above 342 µmol/L (20 mg/dL) (odds ratio, 2.96; 95% confidence interval, 1.29-6.79). This association was not observed among female subjects. We conclude that severe neonatal hyperbilirubinemia, among full-term male newborns with a negative Coombs test, could be associated with lower IQ scores at 17 years of age.
