In our 2018 CHC  chapter   Joel Schneider and I made our long standing affection for visual imagery (Gv-IM per CHC taxonomy) very clear.  See text excerpt below. (double click on images to enlarge) Today I ran across a potential free PDF book (via  Research Gate ) that may make IM tests viable.  There is hope. from IQ's Corner https://ift.tt/3xrh9b0 via IFTTT https://ift.tt/3aBERXW

 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/GIA scores.  The result is the table inserted below (double click to enlarge).  I believe the table is self-explanatory.  A nice PDF copy can be downloaded here.   Enjoy. from IQ's Corner https://ift.tt/3vgDvd7 via IFTTT https://ift.tt/3ayyDrN

https://ift.tt/3xovhBu Abstract Despite 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 cohort studies comprising 48,558 participants in the United States and United Kingdom from 1957 to the present. We found that ability measured in youth has a positive association with most occupational, educational, health, and social outcomes later in life. Most effects were characterized by a moderate to strong linear trend or a practically null effect (mean  R 2  range = .002–.256). Nearly al...

Abstract This 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 vs. post-Kim was non-significant. Different moderators such as scoring methods, instructional settings, intelligence facets, and task modality were tested together with theoretically relevant interactions between some of these factors. These moderation analyses showed that the intelligence–DT relationship can be higher (up to  r  = .31–.37) when employin...

The Relationship between Theory of Mind and Intelligence: A Formative g Approach https://doi.org/10.3390/jintelligence9010011 Ester Navarro ,  S. A. Goring ,  A. Conway Published 2021 Medicine Journal of Intelligence Theory 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 specify g as a formative latent variable, that is, an overall index of cognitive ability that does not represent a psychological attribute (Kovacs and Conway 2016). Here we consider a formative g approach to the relationship between ToM and intelligence. First, we conduct...

Limited Internal Comparability of General Intelligence Composites: Impact on External Validity, Possible Predictors, and Practical Remedies https://journals.sagepub.com/doi/pdf/10.1177/10731911211005171 Silvia Grieder1 , Anette Bünger1 , 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 test batteries (i.e., internal score comparability), thereby minimizing transient error and ruling out between-battery variance completely. We (a) determined the magnitude of intraindividual IQ differences, (b) investigated their impact on external validity, (c) explored possible predictors for these differences, and (d) examined ways to deal with incomparability...

American Psychological Association.  https://doi.org/10.1037/0000194-015 Abstract Advancements in the measurement of intellectual functioning via individually administered intelligence tests during the early 1900s led to reliance on IQs to represent the deficits in intellectual functioning during the past century. Concurrent development of models of intelligence also advanced understanding and measurement of intellectual functioning, and the current consensus is that intellectual functioning is best represented by a latent ability referred to as general intelligence (or psychometric g), as well as numerous broad and narr...
