Similarities and Differences Between Intellectually Gifted and Average-Ability Students in School Performance, Motivation, and Subjective Well-Being

Abstract

Terman’s study was the first to systematically document the lives of the intellectually gifted. This cross-sectional study replicates and extends some of Terman’s findings on characteristics of the gifted in childhood, comparing largely unselected samples of gifted ( n = 50) and average-ability ( n = 50) adolescents matched by means of propensity score matching. Students were compared on their school performance (standardized math and reading tests and grades), motivation (math ability self-concept, intrinsic motivation, vocational interests, and educational aspirations), parental educational expectations, students’ evaluation of school instruction (perceived quality and pressure), and subjective well-being. The gifted scored higher on math performance (rank-biserial r = .66/.81), math ability self-concept (.71), intrinsic motivation (.62), and investigative vocational interests (.65). Some smaller differences were found for realistic (.42) and social interests (–.37) and for pressure in math lessons (–.52). Results support Terman’s findings on gifted individuals’ psychological functioning and contradict negative stereotypes about the gifted.
