During the initial 30 min of recovery after immobilization, social support reduced female stress-related behavior, but only males increased social behavior following immobilization. (A,B) Immobilized females recovering alone displayed significant increases in stress-related behavior, including rearing, self-grooming, and route tracing as well as a composite score that accounts for all stress-related behaviors (i.e., stress index), values represent a raw change score in female stress-related behaviors (post-stress minus pre-stress values). (C,D) Females did not change their social behavior after being immobilized, values represent a raw change score in female social behaviors. (E,F) Males increased their display of social behaviors when their female partners returned after experiencing immobilization, values represent a raw change score in male social behaviors. Bars labeled with asterisks indicate a significant change between pre- and post-stress values as determined by a one-sample or paired t-test (p < 0.05). Data are expressed as mean ± SEM.
