To test this, he teaches a group of students from the CJBS subject pool a lesson and then gives them a test. Half of the subjects are taught by listening to a lecture, the other half are taught by having them complete work sheets.

2. A criminologist is studying college students’ attitudes toward sentences for those convicted of drinking and driving. He is specifically interested in attitude change as a result of years in college and viewing the consequences of drinking and driving accidents. He exposes freshmen, sophomores, juniors, and seniors to photos that depict either mild (broken arms or legs and scratches), moderate (serious injury, broken ribs, people pinned in cars), or strong (deadly accidents, smashed bodies, white sheets covering corpses) visual consequences of drinking and driving accidents. After viewing the pictures, students record their attitudes toward drinking and driving on a questionnaire.
