Dependent variables were standard neuropsychological skill tests drawn from six functional domains, four of which consisted of multiple tests as shown in table 1.
Such considerations ought at least to moderate the strong claims usually made about the predictive validity of IQ tests drawn from correlations with job performance.
Spatial ability was assessed by the Jigsaws and Hidden Shapes tests, drawn from the National Foundation for Educational Research Spatial Reasoning 8 14 series (Smith & Lord, 2002).
Children's intellectual function was assessed on tests drawn from the Wechsler Intelligence Scale for Children, version III, by summing weighted items across domains to create Verbal, Performance, and Full-Scale raw scores.
We supplemented the computerized battery with three non-computerized tasks (counting, transcoding and understanding of the base-10 system), which were sub-tests drawn from the TEDI-MATH battery [ 65].
Children's intellectual function on tests drawn from the Wechsler Intelligence Scale for Children, version III, was assessed by summing weighted items across domains to create Verbal, Performance, and Full-Scale raw scores.
Non-stimulated blood glucose comparisons [ ad libitum (A.L .-fed or fA.L .-fed-stimulated blord glucose values were obtained fastedoung-adult mice at the beginnings of A.L.-fed and fasted glucose tolerance tests, drawn from a small nick at the tip of the tail and measured with a blood glucose monitoring system (glucometer and testing strips) (OneTouch Ultra 2, Lifescan, Inc., Milpitas, CA).
Another study, conducted in Bangladesh with children 10 years of age, showed inverse relations between concentration of Mn in tube-wells and Full-Scale, Performance, and Verbal raw scores derived from tests drawn from the Wechsler Intelligence Scale for Children (WISC-III) (Wasserman et al. 2006).
Questions on the three-hour, four-part test are drawn from high school curriculums, not general knowledge, designed to test how much students have learned rather than how smart they are.
