Charles Spearman and L. L. Thurstone were pioneers in the field of intelligence. They not only developed methods to assess and understand intelligence, but also developed theories about its structure and function. Methodologically, their approaches were not that distinct, but their theories of intelligence were philosophically very different --…

W scores are used in a number of commercially available tests. Due to their complex nature, it can be hard for applied researchers and practitioners to understand them or even acquire information about them beyond what is provided in technical manuals. In this article, we provide information regarding the background and derivation of W scores that…

In the late nineteenth and early twentieth century, a number of Italian psychiatrists were convinced that medicine and education should work together to treat children with mental disabilities, then commonly defined as "feeble-minded". To this end they promoted the establishment of "Medico-Pedagogical Institutes", institutes,…

Background: School attainment tests and Cognitive Abilities Tests are used in the United Kingdom to set targets for educational outcome. Whilst these are good predictors, they depend not only on basic ability but also on learnt knowledge and skills, such as reading. Method and Aims: VESPARCH is an online group test of verbal and spatial reasoning,…

James R. Flynn is an accidental IQ specialist. In the early 1980s, the American-born political scientist thought he might spend a few pages in a planned book on "how to defend humane ideals" grappling with the argument that the gap in IQ scores between blacks and whites was genetically rooted. It was not his first foray into that subject, but this…

In recent years, there have been attempts to diminish the privileged position held by the construct of intelligence. Made pre-eminent by such luminaries as Binet, Terman, and Spearman, recently traditional intelligence has been demoted to simply another variable. With the rise of multiple intelligence and emotional intelligence, traditional…

Each year in the fall and spring semesters, the Peabody Picture Vocabulary Test and the Test de Vocabulario en Imágenes are administered to a sample of pre-K students in AISD. The following report provides Fall 2013 results for each vertical team of schools.

This article addresses giftedness in the context of individual response that emerges as a quality of gifted as differentiated from that which is measurable. The author recounts examples that reflect insight rather than those that simply produce correctness and proficiency. With reference to Gunnar Myrdal, she discusses this difference as a…

It is almost self-evident that test results will be unreliable and misleading if those undergoing assessments do not make a full effort on testing. Nevertheless, objective tests of effort have not typically been used with young adults to determine whether test results are valid or not. Because of the potential economic and/or recreational benefits…

Psychologist Robert J. Sternberg's conviction that American standardized testing does not accurately reflect a child's intelligence or potential is far from theoretical. As an elementary school student in the 1950s, he scored poorly on the ubiquitous IQ test of the time, freezing up when the school psychologist entered the room. Thankfully for…

The General Ability Index (GAI) and Cognitive Proficiency Index (CPI) are two index scores that can be calculated for the Wechsler Intelligence Scale for Children-Fourth Canadian Edition (WISC-IV[superscript CDN]). The GAI comprises the verbal comprehension and perceptual reasoning subtests and reflects reasoning abilities. The CPI includes the…

The ranking of Wechsler subtests in terms of their "g" loadings is equivalent to ranking them in terms of the cognitive complexity of the tasks measured. Lower performing groups do not always fall behind higher performing groups the more complex the task. But that is the general rule, no matter whether the cause of the lower performance…

Flynn has proposed a grand integrative theory, which he calls "scientific spectacles," to explain the phenomenon of rising IQ scores across multiple decades known as the Flynn effect (FE). In his theory, he purports that modern society has placed increasing value and emphasis on the application and education of scientific…

The assessment of cognitive ability in students with the most severe disabilities presents a challenge to the clinicians who are charged with this task. This article is the second of a two-part series that summarizes what is currently known about effective assessment of the cognitive ability of students with significant impairments in order to…

Joel seemed blessed with remarkable talents, but they did not reveal themselves in any obvious way in a school or class setting. Although he had been given an IQ test, his exact score could not be calculated--but it was well over 160. On a test of musical ability, Joel had attained a perfect score on all four musical attributes--a first for the…
