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 I Am a Word (IAW) test represents a distinct method for assessing verbal abilities, offering an open-ended and untimed format designed to accommodate a diverse range of examinees. This approach promotes genuine responses while fostering inclusivity and engagement in testing environments. Background The IAW test emerged as a response …
This review examines the findings of Sauce, Liebherr, Judd, and Klingberg (2022) on how digital media influences cognitive development in children. By incorporating genetic data and controlling for socioeconomic factors, the study offers an evidence-based approach to understanding the effects of screen time, video gaming, and social interactions on intelligence …
Burgoyne, Harris, and Hambrick’s (2019) study examines how individual differences, including cognitive ability, music aptitude, and mindset, influence the acquisition of piano skills among beginners. By focusing on individuals with little to no prior experience, this research offers insights into the early stages of learning a musical instrument. Background The …
The study by Kaminski et al. (2018) investigates the intricate relationships between genetic, epigenetic, and neurobiological factors that contribute to variability in general intelligence (gIQ). By focusing on dopamine D2 receptor (DRD2) gene modification, gray matter density, and striatal functional activation, the research sheds light on the complex interplay influencing …
The connection between education and intelligence has long been a subject of scientific inquiry. Ritchie and Tucker-Drob’s (2018) meta-analysis provides significant insights into this relationship, offering evidence that additional years of education can enhance cognitive abilities across various life stages and cognitive domains. Background Research on intelligence has consistently debated …
Abstract This study aimed to investigate the relationships between tasks of the Jouve Cerebrals Crystallized Educational Scale (JCCES) and General Ability Measure for Adults (GAMA) using multidimensional scaling (MDS) analysis. The JCCES measures Verbal Analogies, Mathematical Problems, and General Knowledge, while the GAMA assesses nonverbal cognitive abilities through Matching, Analogies, …
Abstract This study aimed to examine the relationship between the Jouve Cerebrals Crystallized Educational Scale (JCCES) and the American College Test (ACT) by conducting a factor analysis. The dataset consisted of 60 observations, with Pearson’s correlation revealing significant associations between all variables. The factor analysis identified three factors, with the …
