This review integrates and evaluates the environmental-preservation research published during the 1980s. The focus is environmental behavior change as targeted by behavior analysts and others designing interventions to encourage environmental-preservation behavior. A modified taxonomy of behavioral interventions, based on a taxonomy presented by Geller et al., categorizes these reported interventions by antecedent and consequence conditions. Fifty-four studies were categorized and evaluated according to which of these taxonomic interventions were reported. The conclusions were that (a) antecedent conditions using commitment, demonstration, and goal-setting strategies were generally most effective in encouraging environmentally responsible behavior, and (b) consequence conditions were effective in producing behavior change during the experiment's duration. However, some other important findings were that (a) much of the research in this field during the 1980s did not directly compare interventions, (b) few meaningful follow-up measures were reported, and those evaluations that included follow-up assessment showed little maintenance of the behavior changes, and (c) many potentially effective intervention strategies have been ignored (i.e., group interventions and penalties). Suggestions for future directions of research to produce and maintain environmental-preservation behaviors are offered.

Students in 4 classes had a short exam at the start of every class.Grades were significantly better than in previous classes where the same material was taught but with only 4 exams, and there were fewer withdrawals from the exam-a-day classes. Students taught with the exam-a-day procedure also performed better on a retention test than did students from classes taught using less frequent exams. Responses to anonymous questionnaires administered in all 4 classes indicated that most students believed having an exam every day led to more studying and better learning than in their other classes and that they liked the procedure.
