With humans there are more variables affecting them as well as more ethical considerations. It is sometimes useful to make scientific generalizations using animals because they are easier to study than humans. For example, Bevins (2001) introduced a study on cocaine and novelty. The design of this experiment had a chamber with some novel stimulus and one with out.
