Recent research highlights how everyday physical activity can benefit cognitive health. A study by Hakun et al. (2024) examined the short-term effects of regular physical activity on mental processing speed and working memory. Using real-time assessments, the study provides new insights into how light and moderate physical activities can promote …
A recent study by Denisova and Wolpert (2024) investigates how early sensorimotor features relate to cognitive differences in toddlers diagnosed with autism spectrum disorder (ASD). By examining over 1,000 children with varying IQ levels, the researchers reveal how sensorimotor variability impacts behaviors linked to autism, providing valuable insights for individualized …
Understanding how genetic and environmental influences shape cognitive abilities remains a cornerstone of psychological research. Jiang et al. (2024) present an important study that examines these influences through a structured twin-based model. This research provides insight into how basic and higher-order cognitive functions are differentially affected by genetic inheritance and …
Recent research by Jiang et al. (2024) sheds light on the distinct genetic and environmental influences shaping hierarchical cognitive abilities in adults. By categorizing cognitive functions into two levels—basic processes and higher-order functions—this study provides valuable insights into how these abilities develop and differ in their origins. Background Human cognition …
This post examines findings from Chris Dawson’s research on the connection between cognitive ability and optimism bias in financial decision-making. Using data from over 36,000 individuals in the U.K., the study highlights how cognitive ability influences unrealistic optimism, particularly in financial expectations versus actual outcomes. Background Optimism bias refers to …
Research into high intelligence provides valuable insights into human cognitive abilities and their impact on individual and societal progress. By exploring the historical development of intelligence studies, the challenges of measuring exceptional cognitive abilities, and recent advancements in neuroscience and psychometrics, this article highlights the ongoing importance of understanding high-IQ …
The Wechsler Adult Intelligence Scale (WAIS), developed in 1955 by David Wechsler, introduced a broader and more dynamic approach to assessing cognitive abilities. Over the years, it has been refined through several editions, becoming one of the most widely used tools in psychological and neurocognitive evaluations. This post reviews its …
The Scholastic Assessment Test (SAT) has been a central element of academic assessment in the United States for nearly a century. Initially designed to provide an equitable way to evaluate academic potential, its evolution reflects shifts in societal values, educational theories, and cognitive research. This post examines the SAT’s historical …
The Automated Memory and Executive Screening (AMES) tool, introduced by Huang et al. (2023), represents a significant step in identifying early cognitive decline. Designed for use in primary care settings, AMES evaluates cognitive domains such as memory, language, and executive function. This post reviews the study’s findings and the tool’s …
Sørensen, Fjell, and Walhovd’s 2023 research introduces Generalized Additive Latent and Mixed Models (GALAMMs), a methodological advancement designed for analyzing complex clustered data. This approach holds particular relevance for cognitive neuroscience, offering robust tools for examining how cognitive and neural traits develop over time. Background Traditional models used in cognitive …
