Two studies are reported: one examines stereotypes about only children and the other examines stereotypes about mothers of only children. A sample of 150 college students were the subjects for the first study which utilized the Prisoner's Dilemma Game, the NASA exercise, and a questionnaire to test the hypotheses that only children are selfish, lack social skills, are autonomous and suffer as a result of being only children. The only hypothesis that held up was that only children appear to be more autonomous. The second study interviewed 76 mothers of college undergraduates through a mail survey, providing information as to why mothers of only children have one child. Answers were given relevant to age, education, birth complications, and folklore beliefs. (MS)
