Acquisition of Spanish perfective aspect: a study on children's production and comprehension

Abstract

This paper presents the acquisition of Spanish perfective aspect in production and comprehension. It argues that, although young children use perfective aspect to talk about completed events, young children have difficulty in assessing perfective meaning from perfective morphology. This paper proposes that in the process of acquiring aspectual meaning, children use local strategies to decode aspectual meaning from form: when analyzing a completed situation, young children depend on certain learnability factors to correctly assess the entailment of completion of the perfective, namely, their ability to determine if the object of the event measures out the event as a whole or not, and their ability to read the agent’s intentions. When those factors are removed from the situation, young children had difficulty determining the entailment of completion of perfective aspect. This study also suggests that the manner in which aspectual information is conveyed in a language, may play a role on the readiness of the acquisition of the semantic morphology of the language (e.g., verb+object vs. verb+affixes). The results of this study indicate that successful performance on the semantics of Spanish perfective aspect develops around the age of 5-6.
