Group: a collection of individuals who have relations to one another that make them interdependent to some degree e. g. people in an elevator aren"t a group until they engage in joint action. Triplett (1898): had child participants turn a shing reel as fast as they could in 6 trials. Participants were alone for 3 trials + alongside another participant for the rest. Children reeled faster in the presence of another child doing the same thing. Social facilitation: the presence of others facilitated their performance. Subsequent experiments extended triplett"s ndings in two ways: the same e ects were obtained with the presence of passive observers, the same e ects were observed in many animal species. Allport (1920): asked undergraduate students to refute philosophical arguments as best they could in a 5-minute period.
