Anselmi, Robusto, and Cristante (2023) propose a novel approach to improving Computerized Adaptive Testing (CAT) by integrating unidimensional test batteries. This method aims to enhance both the accuracy and efficiency of ability estimation by dynamically updating prior estimates with each test response. Background Computerized Adaptive Testing has been a widely …
The Jouve–Cerebrals Test of Induction (JCTI) is a nonverbal measure of inductive reasoning. Using data from N = 2,306 examinees, this study assessed score reliability and concurrent validity against external benchmarks. Findings indicate stable internal consistency and strong convergence with quantitative and nonverbal indicators, supporting use in educational and vocational …
The Jouve-Cerebrals Crystallized Educational Scale (JCCES) has been thoroughly evaluated for its reliability and consistency. This large-scale study, involving 1,079 examinees, utilized both Classical Test Theory (CTT) and Item Response Theory (IRT) methods to analyze the scale’s performance and internal structure. Background The JCCES was developed to measure crystallized cognitive …
The Jouve-Cerebrals Figurative Sequences (JCFS) is a self-administered test designed to measure nonverbal cognitive abilities, focusing on pattern recognition and problem-solving. This post outlines the psychometric evaluation of the JCFS, emphasizing its reliability and practical applications while acknowledging areas for future development. Background The JCFS was developed to provide a …
The Jouve-Cerebrals Word Similarities (JCWS) test offers a detailed approach to assessing vocabulary and verbal reasoning abilities. This post examines the psychometric properties of the test, focusing on its reliability, validity, and potential applications in academic and clinical settings. Background The JCWS test builds on the foundation established by the …
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 …
The Flynn effect, which refers to the steady rise in intelligence test scores observed over decades, has been a subject of significant interest in psychological research. While this phenomenon has been extensively documented in European populations, fewer studies have explored its presence or reversal in the United States, especially among …
Shields et al. (2023) examined the effectiveness of the National Institutes of Health Toolbox Cognition Battery (NIHTB-CB) in identifying cognitive development and changes in individuals with intellectual disabilities (ID). The study focused on groups with fragile X syndrome (FXS), Down syndrome (DS), and other forms of intellectual disability (OID), offering …
Leifeng Xiao and Kit-Tai Hau’s article, “Performance of Coefficient Alpha and Its Alternatives: Effects of Different Types of Non-Normality,” examines how coefficient alpha and other reliability indices perform under varying conditions of non-normality. The study offers critical insights into how these measures behave across different data structures, providing useful recommendations …
This review focuses on the work of Keuschnigg, van de Rijt, and Bol (2023), who explore the relationship between cognitive ability and success in high-income and high-prestige occupations. Their findings challenge the assumption that the highest earners consistently display exceptional cognitive ability, offering new insights into how social factors and …
