The results seriously question whether achievement norms govern status attainment for female scientists and whether science is, in fact, unique in its normative structure. (Author/AM)

One hundred and fifty psychology students, assigned to five groups, used different learning strategies (repetition, paraphrasing, linking, grouping, and hierarchy) to study three structurally different chemistry texts. The strategies that demanded recognition of linked relationships as well as retention of this information increased students'…
