Journal ArticleDOI
Identifying Academically Gifted English-Language Learners Using Nonverbal Tests A Comparison of the Raven, NNAT, and CogAT
TL;DR: The authors compared the validity of three nonverbal tests for the purpose of identifying academically gifted English-language learners (ELLs) and found that none of the tests predict achievement for ELL students very well.
Journal ArticleDOI
Consistencies in sex differences on the Cognitive Abilities Test across countries, grades, test forms, and cohorts.
David F. Lohman,Joni M. Lakin +1 more
TL;DR: An astonishing consistency in sex differences across countries, grades, cohorts, and test forms is shown and implications for the current debate about sex differences in quantitative reasoning abilities are discussed.
Journal Article
The Commonality of Extreme Discrepancies in the Ability Profiles of Academically Gifted Students
TL;DR: Lohman and Hagen as discussed by the authors introduced a method for categorizing score profiles and finally document the reliability and stability of score profiles using the 2000 standardization data of the Cognitive Abilities Test.
Journal ArticleDOI
The Predictive Accuracy of Verbal, Quantitative, and Nonverbal Reasoning Tests: Consequences for Talent Identification and Program Diversity
Joni M. Lakin,David F. Lohman +1 more
TL;DR: In this article, the authors assessed the accuracy of measures of verbal reasoning, quantitative reasoning, nonverbal reasoning, and current achievement for predicting later achievement and found that seemingly small differences in predictive validity substantially changed the number of students erroneously included or excluded from the program.
Journal ArticleDOI
Sex differences in reasoning abilities: Surprising evidence that male–female ratios in the tails of the quantitative reasoning distribution have increased
TL;DR: In this article, the results were consistent with previous research, showing small mean differences in the three domains, but considerably greater variability for males. But the most surprising finding was that, contrary to related research, the ratio of males to females in the upper tail of the quantitative reasoning distribution seemed to increase over time.
