a nonsignificant trendp =.057
The difference between partners was not significant for any of the chimpanzee infants, the Gombe infants, F (1,11) = 1.462, p =.252, eta p 2 = 0.25, or the PRI infants, F (1,2) = 2.378, p =.23, eta p 2 = 0.543, although there was a nonsignificant trend (with a large effect size) in the Chester chimpanzee infants, F (1,3) = 0.075, p =.057, eta p 2 = 0.75.
