Renee (a 24-year-old Master's student) was studying attitudes toward women using a questionnaire about affirmative action for women. She hypothesized that male participants would express more support for affirmative action for women when they expressed their attitudes toward a female experimenter, compared to a male experimenter. Renee randomly assigned a group of male college students to have their questionnaire administered by her or by her male advisor, a 50-year-old professor of psychology. She conducted the study in two identical classrooms at the same time of day. Renee found that the men tested in her own room reported more support for affirmative action for women, compared to the men tested by her advisor. She concluded that the gender of the examiner can make men express more liberal gender attitudes.

d. Decide whether the study is subject to any of the internal validity threats listed in Table 11.1.

e. Indicate whether you could redesign the study to correct or prevent any of the internal validity threats.
