Abstract
Public Significance Statement.Children with stronger spatial skills at age 5 are more likely to achieve higher scores in mathematics at ages 7 and 17. Visuospatial working memory partly explained this link, and early spatial skills showed a direct and robust association with later mathematics. This study identified early spatial skills as an important long-term predictor of mathematics from preschool through adolescence. The findings highlight the potential of infusing spatial thinking and using spatial strategies to better understand and solve mathematics problems.

Research Byte: #Cognitive #aging revisited: A cross-sectional analysis of the #WAIS-5 - #intelligence #developmental #cognition #schoolpsychologists #WAISV #schoolpsychology
Historical cross-sectional approaches examining cognitive aging consistently reveal a pat-tern of steady decline on nonverbal problem-solving, speeded tasks, and maintenance on verbal tasks. However, as measures developed and broadened the factor structure to align with Cattell–Horn–Carroll (CHC) theory, and age ranges were extended from 75 to 90 years, a more nuanced approach to cognitive aging emerged. The present study, using the Wechsler Adult Intelligence Scale, Fifth Edition (WAIS-5), examined the cognitive aging process through a cross-sectional approach. WAIS-5 normative sample data (aligned with the 2022 U.S. census) were obtained from the test publisher. The sample included adult participants aged 20–24 through 85–90 (n = 1660), which were mapped into 11 age groups. Using post-stratification weighting to control for educational attainment, cognitive decline was observed throughout aging; verbal skills were maintained longer than other abilities, while processing speed declined steadily and rapidly from young adulthood to old age. Working memory was vulnerable to the aging process but demonstrated slower patterns of decline than the other vulnerable abilities. Fluid reasoning and visual spatial skills (although aligning with separate CHC broad abilities theoretically) were strikingly similar in their pattern of decline across a person's lifespan. Results are highly consistent with the large body of cross-sectional research conducted during the previous generation by Salthouse and his colleagues, as well as other teams of researchers.

CHC Theory (2009) article hits 2000+ citations. Thanks.
2005 citations since 2009!!!!!
On occasion I check my Google Scholar profile. Yesterday I was pleased to see that my most frequently cited peer-reviewed journal article (CHC theory and the human cognitive abilities project: Standing on the shoulders of the giants of psychometric research—Intelligence) had achieved the 2000+ (n=2005) total reference citations mark. This clearly has been my most important peer-reviewed journal contribution to the field of intelligence and human cognitive abilities.
Thanks to all who have found the article useful. And a special thanks to Dr. Doug Detterman. After making an ISIR presentation about this topic, Doug, who was then the editor of Intelligence, invited me to submit an article.

National Academies report: Blueprint for national prevention infrastructure for #mental #emotional #behavioraldisorders
Available to download for free at this link.
SUMMARY
This report provides a blueprint to develop the infrastructure to deliver programs that reduce risk factors (characteristics associated with a higher likelihood of negative outcomes) and promote protective factors (characteristics that can reduce the negative impact of a risk factor and promote better outcomes) for MEB disorders across the life course and in an array of settings. The committee’s charge was to outline the components and requirements of a well-functioning infrastructure to support the delivery of evidence-based programs at federal, state, tribal, and local levels.
