In order to determine the effects of gender and scholastic ability on vocabulary retention and reading comprehension in a foreign language, 181 men and women enrolled in a first-year Spanish course were asked to either read a passage in Spanish on a computer and create annotations for a list of words found in the passage (experimental group), or simply to read the already annotated passage (control group). They were administered vocabulary and reading comprehension tests, and a questionnaire concerning their attitude toward the task. Results showed rather complex interactions between the variables of sex and ability. Although the differences overall failed to achieve statistical significance, an analysis of the attitude questions separately resulted in several significant interactions for gender.
