Document Summary
12 month old lost discoimination abilities but can learn them with exposure adult results: test accuracy at identifying structure-violating patterns for nonisochronous, systematic wrong answers: summary: 12 month old don"t discriminate but exposure for 20 min. for 2 weeks (trained), they can be accultured adults cannot discriminate with similar exposureslight learning, failed to attain native-like performance on non-western rhythms underscores the importance of early learning. Trainor & trehub (1992) infant perception of scale structure experiment 1: conditioned head-turn (8-9 month old) d" measures how accurate you are & factors out bias infants are equally good at diatonic vs nondiatonic adults better at non diatonic. Results: both can discriminate between standard & changed non-diatonic changes is much easier for adults infants are equivalent enculturation to infants: e ect of scale type & tuning changes. Enculturation summary: enculturation ---> babies lose innate ability to make phoneme discriminations.
