SUDA, WILLIAM, and FouTS, GREGORY. Effects of Peer Presence on Helping in Introverted and Extroverted Children. CHILD DEVELOPMENT, 1980, 51, 1272-1275. The effects of peer presence and introversion-extroversion on children's helping in an emergency situation were examined. 38 introverted and 38 extroverted sixth-grade children were tested in the presence or absence of a same-sex confederate peer, with the emergency being sounds of distress in an adjoining room. In the presence of a peer, more extroverts actively helped than introverts, with no difference occurring for children tested alone. Collapsing over the peer-presence and peerabsence conditions, introverts and extroverts were found to prefer passive and active styles of helping, respectively.
