Cross-temporal meta-analytical evidence for better test performance (1990–2021) - ScienceDirect<div name="messageBodySection"> <div dir="auto"> Is there a Flynn effect for attention? Cross-temporal meta-analytical evidence for better test performance (1990–2021) - ScienceDirect <br /> https://www.sciencedirect.com/science/article/pii/S0191886923003409?via%3Dihub<br /> <br /> 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 increase in overall errors and processing speed in children. Our results are consistent with the idea that IQ test score changes may be rooted in changes in executive functioning components and provide further support for domain-specificity of the Flynn effect.</div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

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 (</span><em style="color:#2e2e2e;font-family:ElsevierGulliver, Georgia, Times New Roman, STIXGeneral, Cambria Math, Arial, Helvetica, Lucida Sans Unicode, Microsoft Sans Serif, Segoe UI Symbol, Arial Unicode MS, serif">n</em><span style="color:#2e2e2e;font-family:ElsevierGulliver, Georgia, Times New Roman, STIXGeneral, Cambria Math, Arial, Helvetica, Lucida Sans Unicode, Microsoft Sans Serif, Segoe UI Symbol, Arial Unicode MS, serif"> = 311) was assessed in 1991, whereas the second cohort (</span><em style="color:#2e2e2e;font-family:ElsevierGulliver, Georgia, Times New Roman, STIXGeneral, Cambria Math, Arial, Helvetica, Lucida Sans Unicode, Microsoft Sans Serif, Segoe UI Symbol, Arial Unicode MS, serif">n</em><span style="color:#2e2e2e;font-family:ElsevierGulliver, Georgia, Times New Roman, STIXGeneral, Cambria Math, Arial, Helvetica, Lucida Sans Unicode, Microsoft Sans Serif, Segoe UI Symbol, Arial Unicode MS, serif"> = 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 quantitative), verbal comprehension, and vocabulary, whereas the 1991 cohort outscored the 2022 cohort on rote calculation, visuospatial relations (mental rotation and identical figures), and verbal meanings. These findings are thought to support one key claim made by James Flynn: generational changes on the specific cognitive abilities and skills tapped by standardized tests should be expected without appreciable or substantive changes in the structure of the intelligence construct identified within generations. This main conclusion is discussed with respect to theoretical causal implications putatively derived from current intelligence </span><a style="background-color:transparent;font-family:ElsevierGulliver, Georgia, Times New Roman, STIXGeneral, Cambria Math, Arial, Helvetica, Lucida Sans Unicode, Microsoft Sans Serif, Segoe UI Symbol, Arial Unicode MS, serif" href="https://www.sciencedirect.com/topics/psychology/psychometric-models" target="_blank">psychometric models</a><span style="color:#2e2e2e;font-family:ElsevierGulliver, Georgia, Times New Roman, STIXGeneral, Cambria Math, Arial, Helvetica, Lucida Sans Unicode, Microsoft Sans Serif, Segoe UI Symbol, Arial Unicode MS, serif">.</span></div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

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. Our traditional methods of assessing intelligence rely heavily on IQ tests and problem solving, which may only reflect certain aspects of intelligence while ignoring the rest. Evaluating a human's aptitude is a challenging task, especially in a non-invasive setup. Also, most neuronal networks are interconnected functionally instead of being discrete. The brain has tremendous plasticity and scope for improvisation.Many people are unaware about their own potential. It is thus crucial, to not only understand the attributes of intelligence but also find definite ways to recognize it correctly. Can intelligence be quantified? Perhaps, understanding the neural underpinnings of intelligence through brain mapping can throw some light on its true nature and help in objective assessment for an individual. Qualitative methods might assist as well. Having a rough idea of innate prowess can be of much significance to an individual and how the society perceives him/her. Aim: Conceptualizing the design of a preliminary easy-to-use, comprehensive research tool that can identify and evaluate various domains of intelligence using psycho-physiological techniques Materials and methods: DSM 5 categorizes neuro-cognition into 6 domains- language, learning and memory, social cognition, complex attention, executive function and perceptual motor function. Identifying all the major domains/subdomains under the ambit of intelligence may be the first step in designing a relevant paradigm. The second step could be to evaluate cognitive ability of an individual using qualitative/quantitative/ mixed methods.An appropriate research tool could be developed by formulating a completely new technique or using one/more known modalities of brain evaluation: electrical activity/magnetic activity/ blood flow hemodynamics /imaging of the brain /cognitive function battery /qualitative methods (questionnaires/interviews). Conclusion: More elaborate understanding of brain may help the world embrace its diversity and coexist joyfully through mutual cooperation. Based on initial findings of a preliminary paradigm, further detailed genetic studies may be integrated to establish whether intelligence is constitutional or modifiable.

This association is stronger than previously reported associations with IQ or EF. This finding was robust across models that used different raters (youth and caregiver) and modeling approaches (second-order vs. bifactor). Our findings indicate that PS is related to general psychopathology symptoms. This research points to processing speed as an important transdiagnostic construct that warrants further exploration across development.</span></div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

Specific reading disabilities (SRDs) are neurodevelopmental disorders that emerge early in development and persist into adulthood. They are characterized by protracted difficulties reading and spelling words with accuracy, reading words and text with fluency, and constructing meaning from written text. This chapter reviews research on SRDs, a disorder characterized by protracted difficulties in reading. It begins with a review of research related to the interrelated issues of prevalence, risk, and identification. These factors are inseparable due to the underlying dimensionality of attributes of SRDs. Relative reading skill profiles define two primary subtypes of SRDs: dyslexia and specific reading comprehension disabilities. The chapter reviews recommendations for interventions for individuals with SRDs, highlighting the importance of systematic and explicit instruction in deficit skills. It concludes with open questions for future research investigating interventions for SRDs</span></div><br><br><div dir="ltr">Sent from my iPhone</div>Kevin McGrewhttp://www.blogger.com/profile/07945625852793502565noreply@blogger.com0tag:blogger.com,1999:blog-11327954.post-61940628551094050182023-04-04T11:24:00.001-07:002023-04-04T11:24:59.460-07:00Model Specification Searches in Structural Equation Modeling Using Bee Swarm Optimization - Ulrich Schroeders, Florian Scharf, Gabriel Olaru, 2023<div name="messageBodySection"> <div dir="auto"> Model Specification Searches in Structural Equation Modeling Using Bee Swarm Optimization - Ulrich Schroeders, Florian Scharf, Gabriel Olaru, 2023 <br /> https://journals.sagepub.com/doi/10.1177/00131644231160552<br /> <br /> <span style="color:#2e3743;background-color:#ebeced;font-family:Roboto, Helvetica Neue, Arial, sans-serif">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 to a model specification (e.g., adding or removing a specific factor), whereas onlooker bees only make minor changes (e.g., adding an item to a factor or swapping items between specific factors). Through this division of labor in an artificial bee colony, the algorithm aims to strike a balance between two opposing strategies diversification (or exploration) versus intensification (or exploitation). We demonstrate the usefulness of the algorithm to find the underlying structure in two empirical data sets (Holzinger–Swineford and short dark triad questionnaire, SDQ3). Furthermore, we illustrate the influence of relevant hyperparameters such as the number of bees in the hive, the percentage of scouts to onlookers, and the number of top solutions to be followed. Finally, useful applications of the new algorithm are discussed, as well as limitations and possible future research opportunities.</span></div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

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 configural invariance, 20 studies found weak or partial weak factorial invariance, 12 found strong or partial strong factorial invariance, and 13 found strict factorial invariance. However, the quality of the factorial invariance analyses varied between studies, with some analyses not adopting the hierarchical approach to factorial invariance analysis, leading to ambiguous results. No study that provided interpretable results in terms of the hierarchical approach to factorial invariance found a lack of factorial invariance. Overall, the results of this review suggest that i) the factor analytic models of cognitive abilities generalize across cultures, ii) the use of the hierarchical approach to factorial invariance is likely to find strong or strict factorial invariance, iii) the results are compatible with well-established Cattell-Horn-Carroll constructs being invariant across cultures. Future research into factorial invariance should follow the hierarchical analytic approach so as not to misestimate factorial invariance. Studies should also use the Cattell-Horn-Carroll taxonomy to systematize intelligence research.</span><br /></div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

The motivation to identify "cognitive universals" stems from the close relationship between biology and human cognition and from the theoretical architecture presupposed by the information-processing model. In this article, we argue that the underlying theoretical assumption of universality also stems from epistemological and methodological assumptions that laws of cognition can be effectively developed only by controlling for variables deemed to be outside the scope of internal cognition. These assumptions have resulted in the development of a science of human cognition based on the performance and behavior of a White, English-speaking, normatively invisible, racially color-evasive, socially dominant (WEIRD) class. In this article, we identify how scientific racism has influenced the study of cognition and offer perspective on how researchers may reconsider many of the premises that undergird our approach.</span></div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

<br>It Runs in the Family: Testing for Longitudinal Family Flynn Effects
<br>
<br>The Flynn effect refers to increases over time in measured (particularly fluid) intelligence of approximately 3 IQ points per decade. We define the Flynn effect at the family level, using longitudinal data and two new family-level cohort definitions. Multilevel growth curve analyses of the National Longitudinal Survey of Youth 1979 data showed that children in families with later-born mothers had higher average PIAT math scores, and lower average reading comprehension scores and growth, in young and middle childhood. Children in families where the first child was born later had higher average PIAT math, reading recognition, and reading comprehension scores, as well as larger developmental growth. The latter family-level Flynn effects were of higher magnitudes than the usual individual-level Flynn effect found in previous studies. Our results, showing family level-intercept and slope Flynn effects for both maternal birthyear and first child birthyear, have implications for research aiming to explain the Flynn effect.

Though recent research on the United States suggests that a Flynn effect could still be present, or partially present, among child and adolescent samples, few studies have explored differences of cognitive ability scores among US adults. Thirteen years of cross-sectional data from a subsample of adults (n <br /> <br /> = 394,378) were obtained from the Synthetic Aperture Personality Assessment Project (SAPA Project) to examine if cognitive ability scores changed within the United States from 2006 to 2018. Responses to an overlapping set of 35 (collected 2006–2018) and 60 (collected 2011–2018) items from the open-source multiple choice intelligence assessment International Cognitive Ability Resource (ICAR) were used to examine the trends in standardized average composite cognitive ability scores and domain scores of matrix reasoning, letter and number series, verbal reasoning, and three-dimensional rotation. Composite ability scores from 35 items and domain scores (matrix reasoning; letter and number series) showed a pattern consistent with a reversed Flynn effect from 2006 to 2018 when stratified across age, education, or gender. Slopes for verbal reasoning scores, however, failed to meet or exceed an annual threshold of |0.02| SD. A reversed Flynn effect was also present from 2011 to 2018 for composite ability scores from 60 items across age, education, and gender. Despite declining scores across age and demographics in other domains of cognitive ability, three-dimensional rotation scores showed evidence of a Flynn effect with the largest slopes occurring across age stratified regressions.</div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

Most research has focused on Flynn's main finding: IQ scores have increased over time. Flynn (1987) presumed the effect was a cohort (generational) effect, yet a variety of within- and between-person processes could give rise to the observed secular changes. Many theories have been put forth as to the fundamental cause of the Flynn effect. Frequently ignored is what a specific cause implies the Flynn effect would look like at different levels of analysis and in the context of different research designs. In this paper we present two 'lenses' with which to view a potential causal model of the Flynn effect, in the hopes of closing some of the current gaps emerging from past research. First, we propose an examination of within- versus between-person processes. Relatedly, we propose that the exclusive focus on normed measures of intelligence has hampered understanding of what functional form the Flynn effect might take, particularly during development. Consideration of "raw" intelligence is likely to be fruitful. For our second lens, we consider the framework of age-period-cohort modeling to categorize what kind of effect a given model implies.

Viewed through our lenses, we find that certain causal theories are, perhaps, somewhat incomplete in their specification of all the relevant processes.</div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

Numerous studies have shown that media multitasking is closely related to an individual's cognitive control abilities. However, existing evidence remains controversial, making it difficult to draw definitive conclusions. Therefore, to increase the understanding of whether and how frequent media multitasking is associated with cognitive control, a three-level meta-analysis, which included 43 studies and 118 effect sizes, was performed to acquire overall differences between heavy and light media multitaskers and to explore potential moderators that may account for the heterogeneity. The results showed a moderate mean negative association between media multitasking and cognitive control, and this association was moderated by the type of cognitive control. Specifically, heavy media multitaskers showed worse inhibitory control and working memory than light media multitaskers, but there was no significant difference in cognitive flexibility. Moreover, the effect was moderated by the measurement type of the dependent variable. The results of this study enhance our understanding of this issue and pave the way for a more nuanced view of altering experimental designs to investigate cognitive control in educational settings.</span></div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

But do such differences really exist and, if so, to what extent do they exist and between which cultures are they the most pronounced? To better understand this, we translated a survey from Warne and Burton (2020) on beliefs about intelligence into Arabic, distributed it among psychology and non-psychology students and lecturers at universities within the Arab world, and compared our results with those from the US given by Warne and Burton, and with the current state of research. The survey consisted of 83 items about theories regarding the meaning and testing of intelligence. From our sample of up to 327 Arabic-speaking participants, we found that replies are overall similar to those from the US (r = .59; Nitems = 63), while both samples showed hardly any congruence with the current state of research. Agreements between the Arab and US-sample are mostly to be found on questions in which abilities are seen as important components of intelligence, while Arabs question the predictive validity of IQ test scores for life success much more than do their Western counterparts. Based on our results, we conclude that there is little evidence for the existence of cultural bias in points of view about intelligence research and that the concept of cultural non-transferability – or "cultural bias" – must be examined more critically.</div> </div> <div name="messageSignatureSection"><br /> <div dir="auto">******************************************<br /> Kevin S.

<br>New perspectives on executive functions propose a greater involve- ment of context. These perspectives have implications for research in mathematical cognition. We tackle the problem that although indivi- duals clearly exercise inhibitory control in mathematical contexts, researchers find that the relations between inhibitory control and mathematics are sometimes "weaker than expected." In this review, we identify how children and adults use inhibitory control in specific foundational symbolic and non-symbolic mathematical contexts, with attention to concepts learned in primary (6 to 12) years. Then, we argue that considering context (e.g., task features, participant's state, and prior knowledge) will allow researchers to thoroughly investigate the mechanistic role of cognitive processes involved in mathematical tasks

<br>The field of cognitive training (CT) has been researched for over a century. However, there is still a debate regarding its ability to produce cognitive improvement, especially in working memory (WM) indices. This meta-analysis examined whether there is an advantage in training gains by comparing the results of two specific WM training approaches, Core Training (CRT) and Strategy Training (ST). Meta- analytic techniques were used to summarize 28 independent effect sizes from 24 studies with 1521 subjects, calculated only from studies that compared both training approaches in a single study. We found moderate effect sizes of trained tasks improvement with a clear advan- tage to ST over CRT, from which younger trainees benefitted the most. However, this advantage has almost disappeared for untrained tasks due to the limited improvement each approach produced on its own.

<br>Numbers are present in every part of modern society and the human capacity to use numbers is unparalleled in other species. Understanding the mental and neural representations supporting this capacity is of central interest to cognitive psychology, neuroscience, and education. Embodied numerical cognition theory suggests that beyond the seemingly abstract symbols used to refer to numbers, their underlying meaning is deeply grounded in sensorimotor experiences, and that our specific understanding of numerical information is shaped by actions related to our fingers, egocentric space, and experiences with magnitudes in everyday life. We propose a sensorimotor perspective on numerical cognition in which number comprehension and numerical proficiency emerge from grounding three distinct numerical core concepts: magnitude, ordinality, and cardinality

<br>Mental abilities and physical growth are important determinants of health across the lifespan. Here, the stability of these traits was assessed from 6 months to 65 years of age to investigate periods of stability and malleability. Mental abilities, height, and weight were assessed at 11 time-points in participants of the Zurich Longitudinal Studies. Individuals with more than three missing data points per trait across the 11 assessment time-points (i.e., more than approx. 25% missing data) were excluded from further analyses (final N = 281). Bivariate cross-time correlations showed that the stability of mental abilities was low in infancy and gradually increased. The stability of growth measures was uniform across development, with height being highly stable and weight moderately so. When a latent model was used, the overall stability of mental abilities approached that of weight. The findings indicate that stability and malleability across development differ between mental abilities and growth measures. This requires consideration in interventions targeting these traits as facilitators for improving health outcomes.
