Abstract

The presence of novel objects may be beneficial for the psychological well-being of [isosexual female pairs] captive common marmosets, especially for monkeys with high baseline levels of stress. Such objects reduce boredom through increases in exploratory behavior, decrease the occurrence of stress-related behavior, and do not affect aggression within the pair.
