This document addresses the problems facing researchers who are involved in evaluating worker potential across the life-span, including that most evidence focusing on differential job ability levels within age classifications has come from empirical investigations concerning functional age. A critique of the functional age approach is presented…

During the academic year 1978-79, school teams implemented a newly developed early identification system in all kindergarten and grade one classes in London, Ontario schools. After analysis and revision of the system, the internal consistency and concurrent validity of the process and a test of its short-term predictive validity were investigated.…

A seriation task (assembling a set of nesting cups) was used in this study to examine developmental changes in young children's ability to restructure a situation. Forty young children, eight each at 18, 24, 30, 36, and 40 months of age, participated in the study. Each child was presented with five nesting cups and was told he or she could play…

Because conventional test instruments designed to predict academic performance of the young tend to be inaccurate measures of competence in the elderly, new assessment instruments are being constructed which are more appropriate for current cohorts of the elderly. A comparison of performance on conventional measures to performance on newly…

Children's tendency to answer attitude questions in a biased manner, favoring latter response alternatives when two alternatives are presented in a forced-choice format, was investigated. Using a forced-choice interview format, children were asked questions concerning their attitudes toward mathematics. Each question contained two evaluative…
