Psychology Themes and Variations 6th Edition. Doug McCann, Wayne Weiten & Deborah Matheson TB Indicate the answer choice that best completes the statement or answers the question. 1. Raphael and Paxton are roommates. Because they’re both psychology majors, they choose to dress up as their favourite early psychologists for a Halloween party in their building. They also challenge one another to act like these psychologists all night, and the first one to break character has to take out th...
