Genetically informed, multilevel analysis of the Flynn Effect across four decades and three WISC versions - Giangrande - - Child Development - Wiley Online Library
This study investigated the systematic rise in cognitive ability scores over generations, known as the Flynn Effect, across middle childhood and early adolescence (7 –15 years; 291 monozygotic pairs, 298 dizygotic pairs; 89% White). Leveraging the unique structure of the Louisville Twin Study (longitudinal data collected continuously from 1957 to 1999 using the Wechsler Intelligence Scale for Children [WISC], WISC –R, and WISC–III ed.), multilevel analyses revealed between-subjects Flynn Effects—as both decrease in mean scores upon test re-standardization and increase in mean scores a...

https://www.mdpi.com/2079-3200/8/2/24AbstractNearly a century ago, Spearman proposed that " specific factors can be regarded as the'nuts and bolts'of cognitive performance …, while the general factor is the mental energy available to power the specific engines " . Geary (2018; 2019) takes Spearman's analogy of " mental energy " quite literally and doubles-down on the notion by proposing that a unitary energy source, the mitochondria, explains variations in both cognitive function and health-related outcomes. This idea is reminiscent of many earlier attempts to describe a low-level biological dete...

Full artiThe relation between working memory, number sense, and mathematics throughout primary education in children with and without mathematical difficulties
Number sense and working memory contribute to mathematical development throughout primary school. However, it is still unclear how the contributions of each of these predictors may change across development and whether the cognitive contribution is the same for children with and without mathematical difficulties. The aim of the two studies in this paper was to shed light on these topics. In a cross-sectional design, a typically developing group of children (study 1; N = 459, Grades 1-4) and a group with mathematical difficulties (study 2; N = 61, Grades 4-6) completed a battery of number sense and working memory tests...

EmoSocio: An open access sociometry-enriched Emotional Intelligence model | Semantic Scholar
Significant efforts have been allocated over the last thirty years towards the definition and measurement of the Emotional Intelligence (EI) construct. Several EI theories and models have been produced to support psychological assessment processes. However, barriers are identified for their wide adoption and exploitation by social scientists. The absence of a common structured format to represent concepts in EI models has resulted in lack of clarity and consistency, while hindering comparison, validation and extensive evaluation processes. Provision of open access to such models and measurement instruments has not been pro...

This article builds on the sorites paradox to explore the vagueness that surrounds the concept of intellectual disability and the consequences of this vagueness for the diagnostic process. While epistemicists argue that vagueness is a consequence of our limited knowledge of the world that we live in, semantic theorists claim that there is nothing that we do not know, but that our language allows for indecisiveness. What these different lines of understanding mean for psychologists who are diagnosing intellectual disability, is described in this article.

The evolution of the Woodcock-Johnson (WJ--WJ IV) global IQ or g scores - The WJ is the Elon Musk of IQ testing
 Across the various editions of the WJ Tests of Cognitive Abilities (WJ, WJ-R, WJ III, WJ IV), the authors continually have sought to improve the measurement of intelligence via following contemporary research and theory.  As a result, in contrast to many other IQ tests, the WJ has been known for global IQ scores (original called Broad Cognitive Ability, later changed to General Intellectual Ability) that changed rather dramatically from one revision to the next.  We the WJ authors might be considered to be the Elon Musk of IQ test development.I was recently asked to explain the changing nature of the BAC/GI...

Can You Ever Be Too Smart for Your Own Good? Comparing Linear and Nonlinear Effects of Cognitive Ability on Life Outcomes
https://journals.sagepub.com/doi/full/10.1177/1745691620964122AbstractDespite a long-standing expert consensus about the importance of cognitive ability for life outcomes, contrary views continue to proliferate in scholarly and popular literature. This divergence of beliefs presents an obstacle for evidence-based policymaking and decision-making in a variety of settings. One commonly held idea is that greater cognitive ability does not matter or is actually harmful beyond a certain point (sometimes stated as> 100 or 120 IQ points). We empirically tested these notions using data from four longitudinal, representative coh...

The Relationship between Intelligence and Divergent Thinking —A Meta-Analytic Update
AbstractThis paper provides a meta-analytic update on the relationship between intelligence and divergent thinking (DT), as research on this topic has increased, and methods have diversified since Kim's meta-analysis in 2005. A three-level meta-analysis was used to analyze 849 correlation coefficients from 112 studies with an overall N = 34,610. The overall effect showed a significant positive correlation of r = .25. This increase of the correlation as compared to Kim's prior meta-analytic findings could be attributed to the correction of attenuation because a difference between effect sizes prior-Kim v...

The Relationship between Theory of Mind and Intelligence: A Formative g Approach
https://doi.org/10.3390/jintelligence9010011Ester Navarro, S. A. Goring, A. ConwayPublished 2021MedicineJournal of IntelligenceTheory of Mind (ToM) is the ability understand that other people's mental states may be different from one's own. Psychometric models have shown that individual differences in ToM can largely be attributed to general intelligence (g) (Coyle et al. 2018). Most psychometric models specify g as a reflective latent variable, which is interpreted as a general ability that plays a causal role in a broad range of cognitive tasks, including ToM tasks. However, an alternative approach is to s...

Nice followup and extension of Floyd et al (2018) IQ exchangeability study
Limited Internal Comparability of General Intelligence Composites: Impact on External Validity, Possible Predictors, and Practical Remedieshttps://journals.sagepub.com/doi/pdf/10.1177/10731911211005171 Silvia Grieder1 , Anette B ünger1 , Salome D. Odermatt1 , Florine Schweizer1, and Alexander Grob1 Abstract Research on comparability of general intelligence composites (GICs) is scarce and has focused exclusively on comparing GICs from different test batteries, revealing limited individual-level comparability. We add to these findings, investigating the group- and individual-level comparability of different GICs within ...

Is there a “g-neuron”? Establishing a systematic link between general intelligence (g) and the von Economo neuron - ScienceDirect
 Is there a " g-neuron " ? Establishing a systematic link between general intelligence (g) and the von Economo neuron - ScienceDirect  https://www.sciencedirect.com/science/article/abs/pii/S0160289621000246?via%3DihubAbstractThe construct of general intelligence (g) is one of psychology's most replicated and predictively useful constructs. Although research indicates that g is a highly heritable trait, deeply rooted in brain physiology, to date neither a strong biological correlate nor a comprehensive explanatory model involving neuronal mechanisms have been established. In this article I aim ...
