A study assessed gender differences in confidence for three academic areas of varying gender-type. The study used questions about chemistry (masculine), English (feminine), and art (neutral). Participants were general psychology students (n=361: 229 females, 132 males) who received course credit for their participation. Findings revealed that females underestimated their performance more than did males on chemistry and English questions. (Contains 49 references, 3 notes, and 1 table.) (Author/BT)
