This article introduces a 6P framework for understanding intelligence, as well as the theories and tests that are derived from it. The 6Ps in the framework are purpose, press, problems, persons, processes, and products underlying intelligence. Each of the 6Ps is considered in turn. We argue that although the purpose of intelligence is culturally…

The "Raven's 2 Progressive Matrices Clinical Edition" (Raven's 2; Raven, Rust, Chan, & Zhou, 2018), published by NCS Pearson, is an individually administered nonverbal assessment of general cognitive ability developed to measure "educative abilities," defined as the ability to think clearly and solve complex problems in…

The late James Flynn, to whom this Special Issue is dedicated, suggested that what will matter most to the future of the world is not levels of intelligence but rather how intelligence is deployed. In this article, I argue that we can distinguish between transactional and transformational deployments of intelligence. Loosely following Flynn, I…

The field of giftedness legitimates itself on the basis of correlations of gifted-identification measures with future success that do not mean what they often are taken to mean. When one views the inadequacies of these correlations, the field turns out to be much like the emperor who had no clothes. This essay reviews some of the assumptions upon…

Brian Simon (1915-2002), a Marxist historian and educationist in Britain, was a leading pioneer in the comprehensive education movement. Although Simon's great contribution to this movement has been recognised by historians, the development of Simon's ideas and his actions in this movement have hardly been examined in great depth by previous…

Based on recent findings in cognitive neuroscience and psychology as well as computational models of working memory and reasoning, I argue that fluid intelligence (fluid reasoning) can amount to representing in the mind the key relation(s) for the task at hand. Effective representation of relations allows for enormous flexibility of thinking but…

Brian Simon (1915-2002) was a leading advocate of comprehensive education in the second half of the twentieth century in Britain. In the 1980s, in the face of the ideological offensive from the New Right, he firmly stood by Marxist ideals and resolutely resisted policies of the right-wing leading to the 1988 Education Reform Act. Despite this…

This paper utilizes the concept of 'discriminate biopower' to explore how advancements in social and behavioral genomics might inform the racially exclusionary nature of one of the most inequitable and academically coveted environments in American public education: gifted education. In its birth, gifted education became a mechanism for regulating…

Aim(s): Educational psychology, whilst a helping profession, was heavily influenced by oppressive and racist ideas during its infancy. Over the last several decades, EPs have been invited to hold a mirror up to the profession with regard to racial justice. The aim of this paper is to offer a critical exploration of epistemic issues within…

This brief article introduces the topic of intelligence as highly appropriate for educational measurement professionals. It describes some of the uses of intelligence tests both historically and currently. It argues why knowledge of intelligence theory and intelligence testing is important for educational measurement professionals. The articles…

We explore the cognitive skill gap between the adult population in Spain and in the rest of European Union countries using the Program for the International Assessment of Adult Competencies. We find that differences in schooling account for about a third of the average difference in cognitive test scores, whereas differences in socioeconomic…

This article explores the advantages of viewing intelligence not as a fixed trait residing within an individual, but rather as a person × task × situation interaction. The emphasis in the article is on the role of persons solving tasks embedded in situations involving learning, intellectual abilities, and competencies. The article opens with a…

The concept of differentiation holds immense significance in education, touching upon aspects like access, inclusion, justice, and equality. However, it is also a complex and elusive notion, which acquires different meanings across historical and cultural contexts. This article explores the shifting reasoning about differentiation in the Swedish…

The Cattell-Horn-Carroll (CHC) model presently serves as a blueprint for both test development and a taxonomy for clinical interpretation of modern tests of cognitive ability. Accordingly, the trend among test publishers has been toward creating tests that provide users with an ever-increasing array of scores that comport with CHC. However, an…

The identification, diagnosis, and categorisation of students who qualified for special education have created long-standing controversy. This article explores Maximilian P. E. Groszmann's measurement practices, which were intended to facilitate instruction in the early twentieth-century United States. In 1900, Groszmann established a private…
