Taking another look at intelligence and personality using an eye-tracking approach

L. Bardach, A. Schumacher, et al.

Delve into the fascinating interplay between intelligence and personality with research conducted by Lisa Bardach and colleagues. Discover how gaze patterns during intelligence testing not only reveal our cognitive abilities but also improve predictions of test performance, independent of personality traits. This study redefines our understanding of what contributes to intelligence assessments.

Abstract

This study investigates the relationship between intelligence, personality, and gaze patterns during a timed intelligence test. Using a sample of 182 adults, the researchers employed machine learning models to analyze fluid intelligence scores, Big Five personality traits, and eye-tracking data. Results showed that personality explained a small portion of variance in intelligence test scores, with Openness and Agreeableness being the most significant predictors. Gaze patterns, however, explained a substantial amount of variance in intelligence test performance and were unrelated to Big Five traits but showed some association with certain facets. Combining gaze patterns and personality traits further improved the prediction of intelligence test scores. The study highlights the independent contributions of personality and gaze patterns in predicting intelligence test performance.
