La adquisición de las cláusulas interrogativas parciales en el espa？ol infantil: ？Reglas innatas o fórmulas aprendidas?

according to usage-based theory (tomasello 2006), children acquire wh- questions by initially producing concrete formula structures that happen to be very frequent in the input. in this research we analyze the wh-questions produced by three spanish-speaking children (age range: 0;11-3;11) in longitudinal samples of spontaneous speech to determine whether the usage-based theory can explain the wh-question acquisition in spanish. results show that: i) the first wh-questions are formula, that appeared with few interrogative particles, and that are highly frequent in the input; ii) as the child develops, wh-questions become more complex, in which this structures are produced with more varied interrogative particles and different verbs; iii) the input seems to play a relevant role in the acquisition of wh-questions. results seem to validate the usage-based theory.
