A meta-analysis was conducted to examine the construct validity of language aptitude by synthesizing the existing research that has been accumulated over the past five decades. The study aimed to provide a thorough understanding of the construct by aggregating the data reported in the primary research on its correlations with other individual…

The Naglieri Nonverbal Ability Test, Second Edition (NNAT2), is used widely to screen students for possible inclusion in talent development programs. The NNAT2 claims to provide a more culturally neutral evaluation of general ability than tests such as Form 6 of the Cognitive Abilities Test (CogAT6), which has Verbal and Quantitative batteries in…

Schools often administer brief intelligence tests as the first step in the identification of students who are cognitively gifted. However, brief measures are often used without consideration of underlying constructs or the psychometric properties of the measures and without regard to the links between screening decisions and educational…

The literature pertaining to intelligence assessment reveals an ongoing discussion about the areas of intelligence captured by nonverbal tests. To date, few studies have investigated the criterion validity of the Test of Nonverbal Intelligence, Third Edition (TONI-3). The present study investigates the concurrent validity of the TONI-3 in a sample…

Evaluation of visuoconstructional abilities is a common part of clinical neuropsychological assessment, and the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI; K. E. Beery & N. A. Beery, 2004) is often used for this purpose. However, few studies have examined its psychometric properties when used to assess children and…

In this study, the authors examined the psychometric properties and criterion validity of a newly developed battery of tasks that were designed to assess executive function (EF) abilities in early childhood. The battery was included in the 36-month assessment of the Family Life Project (FLP), a prospective longitudinal study of 1,292 children…

This study investigated whether measures of habituation and dishabituation in early infancy predicted later intelligence. Results were compared with those from other comparable studies. It was argued that the psychometric acceptability of infant cognitive measures needs to be demonstrated before they can be considered to be potential predictors.…

The present study evaluated the criterion validity of the aggregated tasks of basic cognitive processes (TBCP). In age groups from 6 to 19 of the Woodcock-Johnson III Cognitive Abilities and Achievement Tests normative sample, the aggregated TBCP, i.e., the processing speed and working memory clusters, correlate with measures of scholastic…

The predictive power of various cognitive skills at three months of age in terms of later cognitive functioning was examined. Visual habituation and recovery predicted later intellectual functioning at 24 months better than global intelligence or object permanence scores. Changes in cognitive functioning may be a transformation of skills.…

The predictive power of the short-form Wechsler Adult Intelligence Scale of P. Satz and S. Mogel to provide equivalent information about IQ scores and age-corrected scale scores was not differentially affected by the side of the lesion for 63 patients with brain tumors. (SLD)

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…
