Greater male variability in overexcitabilities: Domain-specific patterns

The greater male variability hypothesis posits that males exhibit greater variability than females in both mental and physical characteristics. The hypothesis has been supported in various giftedness-related constructs (e.g., intelligence, talents, creativity). This study extended this line of research to another giftedness-related psychological construct: overexcitability (OE). The Overexcitability Questionnaire-Two was administered to 836 (51% girls) 7–9th graders in Hong Kong to assess the five domains of OE (i.e., psychomotor, sensual, intellectual, imaginational, and emotional). The results suggested a domain-specific pattern of gender differences in the variability of OE scores. Greater male variability was found in the sensual, imaginational, and intellectual OE domains; male superiority was found in the psychomotor domain; and female superiority was found in the emotional domain. These domain-specific findings enrich the discourse surrounding the greater male variability hypothesis. Theoretical and educational implications regarding the findings are discussed.
