Childhood photographs of homosexual and heterosexual men

20 homosexual men and 20 heterosexual men, including a pair of discordant identical twins, contributed photographs of themselves at 6 mo. to 6 yr. of age for judging on personality. 18 traits were rated successfully. Factor analysis yielded two factors, Extroversion and Toughness. Data for only 19 homosexual and 11 heterosexual men were usable for the t tests; no significant differences were found, although trends for the homosexual group suggested less Extroversion and less Toughness. For the twins, photographs the mother identified as the homosexual twin were rated as showing less Extroversion and less Toughness. In conclusion, no obvious differences were found in the ratings of homosexuals' childhood photographs but slight differences were hinted at.
