This document discusses 5 concepts from social psychology: extrinsic motivation, social facilitation, stereotyping and racism, altruism, and self-serving bias. For each concept, it provides a definition and explanation based on a comic about a basketball captain. The captain was extrinsically motivated to win, his performance was facilitated by the crowd, racism was shown when an injured player wasn't helped, one audience member helped altruistically, and the captain displayed self-serving bias by blaming others after losing.
