     Nursery rearing of infant primates has the disadvantage of denying the infant of maternal interaction. Inanimate surrogate mothers were developed to both ameliorate and study the changes in development that maternal separation can cause. Several types of surrogates have been employed in the nursery rearing of non-human primates. Some versions are a simple piece of cloth, a wire surrogate, stationary surrogate, moving surrogate and the more complex motor driven mobile surrogate. They have been used to explore attachment theories, development of exploratory behavior, abnormal behavior and developmental milestones. Surrogates have been used in several species including but not limited to Macaca nemestrina, Macaca fascicularis, Macaca mulatta, and Papio cynocephalus anubis. Research with surrogates has consistently shown that the more complex the surrogate the greater the benefit to the infant. However, the infant’s need for complexity and the laboratory’s need for practicality need to be balanced when implementing the use of equipment in a primate nursery. It is also important to note that no matter how complex, no surrogate is a substitute for regular peer interaction in a nursery setting.
