We present a syntactic analysis of a language with an ergative-absolutive alignment, Shipibo, and a language with a nominative-accusative alignment. This is developed by deploying syntactic schemes in line with Marantz's case distribution hierarchy. Thus, transitive and intransitive utterances of each language have been assessed and compared, considering particular characteristics of each language. It has been noted that Spanish and Shipibo maintain a different case allocation amongst them. Likewise, it has been confirmed that the intransitive utterances of these languages do not exhibit greater differences than the transitive ones. Finally, it has not been possible to confirm whether constructions which share the same alignment could be equivalent between an accusative and an ergative language, given that the split-ergativity example studied in Shipibo maintains the ergative case.

El estudio busca determinar si las estructuras de alternancia de código formadas morfológicamente serán percibidas como gramaticales por hablantes peruanos bilingües en español e inglés. Se propone un análisis neurolingüístico de la alternancia de código, evaluando el fenómeno en torno a su comprensión al momento del procesamiento , a diferencia de los análisis sociolingüísticos previos. La hipótesis es que la ausencia del componente P600 indicaría que las estructuras son percibidas como gramaticales.
