  abstract  = {Is there an ideal time window for language acquisition after which nativelike representation and processing are unattainable? Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming task with a group of Turkish-German bilinguals and examined age of acquisition (AoA) effects on the processing of complex words. We compared a subtle but meaningful linguistic contrast, that between grammatical inflection and lexical-based derivation. The results showed a highly selective AoA effect on inflectional (but not derivational) priming. In addition, the effect displayed a discontinuity indicative of a sensitive period: Priming from inflected forms was nativelike when acquisition started before the age of 5 but declined with increasing AoA. We conclude that the acquisition of morphological rules expressing morphosyntactic properties is constrained by maturational factors.},

  abstract  = {Masked priming research with late (non-native) bilinguals has reported facilitation effects following morphologically derived prime words (scanner - scan). However, unlike for native speakers, there are suggestions that purely orthographic prime-target overlap (scandal - scan) also produces priming in non-native visual word recognition. Our study directly compares orthographically related and derived prime-target pairs. While native readers showed morphological but not formal overlap priming, the two prime types yielded the same magnitudes of facilitation for non-natives. We argue that early word recognition processes in a non-native language are more influenced by surface-form properties than in one's native language.},
