 Is there a Flynn effect for attention? Cross-temporal meta-analytical evidence for better test performance (1990–2021) - ScienceDirect  https://ift.tt/6Fuw8ij Generational IQ test score changes (i.e., the Flynn effect) have been observed for most measures of cognitive ability, although certain cognitive domains appear to be less affected by this effect than others. IQ test score changes have been found to differ between domains, but evidence of Flynn effects for specific IQ-related abilities is sparse. In the present cross-temporal meta-analysis, we investigate potential test score changes for attention as assessed by the d2 Test of attention. Based on data from 287 independent samples (N = 21,291) from 32 countries over a timespan of 31 years (1990–2021) we found evidence for moderate generational test score gains in concentration performance in adults, but not children. While no changes in test effectiveness were found for either age group, there was a substantial incre...

 Generational intelligence tests score changes in Spain: Are we asking the right question? - ScienceDirect  https://ift.tt/JlwFCKd Generational intelligence test score gains have been documented worldwide in the twentieth century. However, recent evidence suggests these increased scores are coming to an end in some world regions. Here we compare two cohorts of university freshmen. The first cohort ( n  = 311) was assessed in 1991, whereas the second cohort ( n  = 349) was assessed thirty years later (2022). These cohorts completed the same intelligence battery including eight standardized speeded and power tests tapping reasoning (abstract and quantitative), language (vocabulary, verbal comprehension, and verbal meanings), rote calculation, and visuospatial relations. The results revealed a global gain of 3.5 IQ points but also upward and downward changes at the test level. The 2022 cohort outperformed the 1991 cohort on reasoning (abstract and quantit...

This is a major factor in why my three blogs are now largely dormant of new creative content from me, and instead, serve as quick FYI posts.  Blogging was great for a while, but one must move with the times.  Perhaps, someday, I'll try TikTok.  Young people are abandoning news websites – new research reveals scale of challenge to media  https://flip.it/rtzoEZ ****************************************** Kevin S.

https://ift.tt/NoIlzAS What is intelligence?: Conceptualising a psycho-physiological paradigm to identify and assess domains of intelligence Megha Agrawal, Gyan Vardhan Published 1 May 2023 Psychology Physiology Background: Even after years of debate, "intelligence" seems to be an obscure concept with no conclusive way of assessment. Intelligence has been categorized differently by various scientists; such as fluid vs crystallized intelligence, Triarchic theory of intelligence, Multiple Intelligence Theory etc. Though scientists have described it in various ways, intelligence is a broad term that encompasses multiple domains, subdomains and cognitive abilities. With growing advances in the field of artificial intelligence, it is still not clear as to what should be classified as intelligence and what shouldn't.It would be worthwhile to explore what intelligence means in qualitative as well as quantitative terms, and how it extends to other animal species too.

 Childhood socioeconomic status and the pace of structural neurodevelopment: accelerated, delayed, or simply different?: Trends in Cognitive Sciences  https://ift.tt/lvI8Z6j Socioeconomic status (SES) is associated with children's brain and behavioral development. Several theories propose that early experiences of adversity or low SES can alter the pace of neurodevelopment during childhood and adolescence. These theories make contrasting predictions about whether adverse experiences and low SES are associated with accelerated or delayed neurodevelopment. We contextualize these predictions within the context of normative development of cortical and subcortical structure and review existing evidence on SES and structural brain development to adjudicate between competing hypotheses. Although none of these theories are fully consistent with observed SES-related differences in brain development, existing evidence suggests that low SES is associated with brain structure trajecto...

 Processing Speed is Related to the General Psychopathology Factor in Youth | SpringerLink  https://ift.tt/efTkJjM The relationship between the  p  factor and cognition in youth has largely focused on general cognition (IQ) and executive functions (EF). Another cognitive construct, processing speed (PS), is dissociable from IQ and EF, but has received less research attention despite being related to many different mental health symptoms. The present sample included 795 youth, ages 11–16 from the Colorado Learning Disabilities Research Center (CLDRC) sample. Confirmatory factor analyses tested multiple  p  factor models, with the primary model being a second-order, multi-reporter  p  factor. We then tested the correlation between the  p  factor and a latent PS factor. There was a significant, negative correlation between the  p  factor and PS ( r (87) = -0.42,  p  < .001), indicating that slower processing speed is a...

 Model Specification Searches in Structural Equation Modeling Using Bee Swarm Optimization - Ulrich Schroeders, Florian Scharf, Gabriel Olaru, 2023  https://ift.tt/psGh3nm Metaheuristics are optimization algorithms that efficiently solve a variety of complex combinatorial problems. In psychological research, metaheuristics have been applied in short-scale construction and model specification search. In the present study, we propose a bee swarm optimization (BSO) algorithm to explore the structure underlying a psychological measurement instrument. The algorithm assigns items to an unknown number of nested factors in a confirmatory bifactor model, while simultaneously selecting items for the final scale. To achieve this, the algorithm follows the biological template of bees' foraging behavior: Scout bees explore new food sources, whereas onlooker bees search in the vicinity of previously explored, promising food sources. Analogously, scout bees in BSO introduce major changes...

Cross-cultural invariance of CHC theories The cross-cultural generalizability of cognitive ability measures: A systematic literature review. - ScienceDirect  https://ift.tt/LMOljYf Abstract Examining factorial invariance provides the strongest test of the generalizability of psychological constructs across populations and should be investigated prior to cross-cultural interpretation of cognitive assessments. The aim of this systematic review was to critically evaluate the current evidence regarding the factorial invariance and the generalizability of cognition models across cultures. The review was structured using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature search identified 57 original studies examining the factorial invariance of cognitive ability assessments across cultures. The results were strongly supportive of the cross-cultural generalizability of the underlying cognitive model. Ten studies found configur...
