A correction was inadvertently omitted from “Social Status in Pairs of Male Squirrel Monkeys Determines the Behavioral Response to Central Oxytocin Administration,” by James T. Winslow and Thomas R. Insel (The Journal of Neuroscience 11:2032–2038, July 1991). On page 2036, the sentence beginning in the seventh line of the second column should read “A similar recalcitrance to change has been reported for subordinate members of talapoin monkey groups (Eberhart et al., 1985).” The publisher regrets this error.
