In this article the authors argue that distinguishing between rationality and intelligence helps explain how people can be, at the same time, intelligent and irrational (Stanovich, 2009). As such, researchers need to study separately the individual differences in cognitive skills that underlie intelligence and the individual differences in…

To promote efficient clinical practice, interest has been growing in brief assessment scales to replace full-scale versions in some circumstances. In nonclinical populations, the Wechsler Abbreviated Scale of Intelligence (WASI) has substituted for the Wechsler Intelligence Scale for Children--Third Edition (WISC-III). Agreement between these…

The data compression aspect of 20th century science is evident in the "mass action" concept of brain function embodied in the "g" model of intelligence and academic tests. This paper sketches the history of the devolution of the "g" model into multifactored intelligences, contrasts dynamic process versus static…

The four basic methods of quantifying severe academic discrepancy to determine learning disabilities are evaluted in terms of ease of administration, measurement errors, regression effects, years in school, changes in variation of achievement scores at different grades, comparability of norms, incidence, and treatment of IQ/achievement…

Research on the Wechsler Adult Intelligence Scale-Revised and Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) suggests that practicing clinical psychologists and graduate students make item-level scoring errors that affect IQ, index, and subtest scores. Studies have been limited in that Full-Scale IQ (FSIQ) and examiner administration,…

Evaluation of teacher performance is usually done with the use of ratings made by students, peers, and principals or supervisors, and at times, self-ratings made by the teachers themselves. The trouble with this practice is that it is obviously subjective, and vulnerable to what Glass and Martinez call the "politics of teacher…

The current study examined the assessment strategies school psychologists used in their everyday assessment routine in the evaluation of students referred for social/behavioral/emotional problems. A stratified, random, national sample of 1,000 members of the National Association of School Psychologists were sent surveys; 667 completed surveys were…
