Effects and Interactions Assignment
A researcher is investigating verbal behaviour among introverts and extroverts. The researcher first tests participants and classifies them as either introverted or extroverted. She then randomly assigns participants to high anxiety or a low anxiety social group and observes the number of words spoken by participants.
The researcher wants to learn more about the effects of both personality style—introversion or extroversion—and social situation—high or low anxiety—on verbal behaviour. In this case, verbal behaviour is defined as the number of verbal communications uttered within a 5-minute observation period.
