Examined the reactions of 36 male undergraduates presented with 1 of 2 emergency situations while alone, with 2 nonresponding student confederates, or with 2 nonresponding child confederates. The prediction that intervention would be maximal when children were present was not supported. Ss responded significantly more rapidly to the emergency when alone than when any confederate was present (p < .025). Ss did, however, respond more rapidly when the children were present than when the adults were present (p < .05). The type of emergency did not result in significant differences in intervention. Explanations to account for these results are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
