Compreensão de estruturas sintáticas com movimento A’ e com movimento A em crianças portuguesas surdas com implante coclear: efeitos da idade de início de exposição ao input linguístico e do tempo de exposição à língua

In the period in which language should be acquired, auditory input deprivation compromises oral exposure. The literature reports difficulties comprehension of syntactic dependencies resulting from A’ movement, but no acquisition structures with A-movement hearing-impaired children hearing aids. Our study investigates effects total linguistic during first year(s) life (critical acquisition) and length exposure on A A-bar movement (Wh- questions, relative clauses, passives) 47 Portuguese cochlear implants. results reveal that CI activation before age 3 combined at least 6 years determines Wh- questions relatives same level as control group. does not happen passives, remain problematic this population even after prolonged We discuss these findings light theoretical proposals attribute passives to maturational constraints.
