Early intermittent separations increase subsequent novelty-seeking behavior. Measures of familiar versus novel object exploration are presented for previously separated and nonseparated monkeys (n = 9–10 monkeys per condition; mean ± SEM). Asterisks signify separation effects (p <.05) and the bracket shows that previously separated monkeys preferred to interact with the novel toy-like object (adapted from data presented in Parker et al., 2007).
