Results indicated that judgments of cross-language similarity, as shown in Experiment 1, predicted the ability to perceive and produce sounds in the second language. Indeed, children, who were less likely to perceptually associate L2 sounds with L1 sounds, displayed a superior ability to produce L2 sounds both at beginning and more advanced levels, suggesting that L2 speech learning in childhood is less constrained by L1 phonology.
