Cognitive ability remains a core construct in psychology and education, yet debates persist regarding the most relevant construct, methodologically rigorous approaches, and its measurement implications. This study aims to conduct a bibliometric study of cognitive measurement published from 2011 to 2025, focusing on global research trends. Using the Dimensions.ai database and Bibliometrix R package, 1,083 journal articles were fit with inclusion criteria, retrieved, and analyzed. Performance analysis revealed a very small, yet not significant, annual growth of publications over fifteen years and a significantly decreased citation rate per document. The analysis also shows that current studies were predominantly published by correspondence authors from German and Anglophone countries. Schulte-Körne emerged as the most productive author, Intelligence as the most impactful journal, and Nisbett’s paper, "Intelligence: New Findings and Theoretical Developments", as the most cited article. Meanwhile, science mapping based on keyword co-occurrence, multiple correspondence analysis, and thematic mapping showed psychology as the central hub connecting related fields. Research regarding cognitive ability measurement was conducted along the lifespan, with motor themes centered on humans and gender, basic themes related to cognition and adulthood, and niche themes including psychometrics and preschool assessment. Overall, cognitive measurement appears as a maturing, interconnected, yet concentrated research domain. Future research should continue to advance toward cross-cultural, cross-disciplinary, and interdisciplinary approaches that prioritize collaboration and the adoption of advanced technologies to foster continued innovation and scientific progress in this field.
