6. Independent Variable: Yawn prompt Dependent Variable: other’s behavior (yawn or no yawn)

7. Experimental group: the group on which the critical part ( variable introduced ) of the experiment is performed. Control group: the group that does not participate ( no variable ) in the critical part of the experiment.

8. Control Group: Classroom with no yawn prompt Experimental Group: Classroom with yawn prompt
