This paper examines parenting practices reported by 29 seniors who won scholarships in the 1990 Westinghouse Science Talent Search (STS) for projects in mathematics or science. It uses measures of parenting developed by Sanford Dornbusch and others: Parents are "authoritative" if they encourage family discussions of controversial topics, prefer democratic decision making, give praise and expand freedom to make decisions for a good grade, and restrict student freedom and encourage improvement in response to a poor grade. "Authoritarian" parents discourage debate and questioning of parents' ideas, get upset and punish their child for a poor grade, and tell the child with good grades to do even better. "Permissive" parents indicate that grades and hard work in school are not important, have no rules about television, are not involved in high school activities, and do not help their child with homework or check to see if it is done. Results indicated that STS students ranked their parents very low on the authoritarian index. (Author/ZWH)
