Abstract:
A captive vervet monkey (Cercopithecus aethiops sabaeus) colony was divided into subgroups to determine the influence of the control male and the control female on the expression of control role behaviors in other group members. Separation from the control male invariably caused an increase in the control male factor score for other adult and subadult males in the colony, and reunion caused a decline to baseline. Separation from the control female produced no consistent behavioral effect in other adult females.
