The present study examined the impact of an experience with adults in sex-role reversed occupations upon elementary school children's sex-stereotyped beliefs. Subjects were 68 children in first, third, and fifth grades from a parochial elementary school in San Leandro, California. The adult occupations test, a paper and pencil assessment instrument designed to measure the sex-role flexibility of children's occupational stereotypes, was used for both the pre- and post-tests. One week after the pre-test, the treatment phase of the study was implemented. Half the males and half the females from each grade listened to talks by a male nurse and a female firefighter. The other half of the children listened to two "sex-role appropriate" adults in the same occupations. Post-tests were administered immediately after the talks. No significant treatment effect was noted, but the trends by age and sex occurred in the expected direction, i.e., average stereotyping scores decreased as subjects' age increased, and boys were more stereotyped than were girls. Item analyses indicated the possibility of specific occupation effects as a result of the treatment. (Author/RH)
