Gender differences in means and variability on creative thinking: Patterns in childhood, adolescence, and emerging adulthood

Gender differences in creative thinking remain an unresolved research question. Researchers have increasingly recognized that both mean and variability analyses should be conducted to uncover a complete picture of gender differences.Moreover, it has been suggested that gender differences in intellectual abilities are dynamic across age, and gender differences needs to be analyzed developmentally. This study employed a developmental perspective to study gender differences in creative thinking based on both mean and variability analyses. Creativity was assessed with the Test for Creative Thinking–Drawing Production (TCT–DP) which was developed based on the componential model of creativity. The TCT–DP scores of six age groups (N = 2,224), which included participants of ages 3-4 years, 5-7 years, 10-12 years, 13-15 years, 18-19 years, and 20-22 years, were analyzed. Results showed that while mean analyses generally revealed trivial gender differences, variability analyses tend to support great gender differences. Furthermore, developmental data demonstrated that the magnitude and the direction of gender differences change across age. While greater female variability (favoring girls) was observed in young children, a reverse pattern that was found in adolescents and young adults. The findings shed lights on the different developmental trajectories of boys and girls in creativity.
