Twenty-five years after the introduction of Carroll's (1993) Three Stratum (3S) theory of intelligence and McGrew's (1997) subsequent synthesis of 3S with the extended Gf-Gc / Horn-Cattell theory, the Cattell-Horn-Carroll (CHC) theory represents the prevailing framework by which the structure of human cognitive and intellectual abilities is…

In the US, undeniable evidence shows that socioeconomic inequities explain a high proportion of individual differences in school achievement. Although not all countries show this same effect due to socioeconomic status, it is consistently found that social inequities lead to achievement gaps. These achievement gaps then manifest into trajectories…

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 --…

Since their emergence in public schools, specific learning disability (SLD) identification practices have been controversial in both research and practice. The purpose of this special issue is to present contemporary research on various models of SLD identification as well as issues associated with their implementation. Each of the articles in…

The incidence of writing disorder is as common as reading disorder, but it is frequently under-identified and rarely targeted for intervention. Increasing clinical understanding on various subtypes of writing disorder through assessment guided by data-driven decision making may alleviate this disparity for students with writing disorders. The…

This article briefly reviews the history of intellectual assessment of children and youth in the United States of America, as well as current practices and future directions. Although administration of intelligence tests in the schools has been a longstanding practice in the United States, their use has also elicited sharp controversy over time.…

As high-stakes testing, Common Core, and state standards become the new norms in schools, teachers are tasked with helping all students meet specific benchmarks. In conjunction with the influx of more students with disabilities being included in inclusive and general education classrooms where lectures with note-taking comprise a majority of…

An increasing number of children are likely to have a known genetic cause for their special educational needs. One such genetic condition is 22q11.2 deletion syndrome (22qDS), a genetic syndrome associated with early speech and language difficulties, global and specific cognitive impairments, difficulties with attention and difficulties with…

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…

A fundamental problem for many struggling readers, their parents, and their teachers is that there are few benchmarks to guide decision making about assistive technological supports when the nature of a disability is cognitive (e.g., specific learning disability, SLD) rather than physical. However, resources such as the National Center on…

This paper is about mothering, young learning disabled people, their sexualised and relationship lives and normalisation--not through the lens of the disabled person, but via a mothers perspective and theoretical discussion. As a mother who has a learning disabled daughter, a feminist and an academic my own mothering experience, my Ph.D. research…

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…

After decades of what seemed to be an inexorable upward path, the number of students classified as learning-disabled declined from year to year over much of the past decade--a change in direction that is spurring debates among experts about the reasons why. The percentage of 3- to 21-year-old students nationwide classified as having a…

A concussion is a serious injury--a mild traumatic brain injury (TBI)--that induces physiological disruption of brain function. A concussion is caused by a bump, blow, or jolt to the head or body. The sudden movement causes stretching and tearing of brain cells; cells become damaged and chemical changes occur within the brain. Concussions can lead…

This paper offers a brief review of the use of metacognition by proficient and poor performers in academic and psychomotor tasks as well as highlights the parallels and provides directions for future research. Metacognition is knowledge about one's own cognitive processes [Flavell, J.H. (1979). "Metacognition and cognitive monitoring: A new area…
