Can NEG placement have negative consequences (for efficient processing)? A bilingual test case

The present study examines the relative processing efficiency of two typologically diverse configurations of sentential negation: immediately preverbal NEG and unbounded clause-final NEG. In order to effect a head-to-head comparison, the data are drawn from a bilingual speech community in the Afro-Colombian village of San Basilio de Palenque, in which two lexically cognate languages are in contact, differing principally in the placement of the sentential negator: Spanish (preverbal NEG) and the Afro-Hispanic creole language Palenquero (clause-final NEG). The results of a series of experiments suggest that preverbal negation is quite robust, while processing of clause-final negation is degraded under increased cognitive demands. Contextual and pragmatic cues ameliorate the processing of likely negative utterances, while unbounded clause-final negation is more vulnerable in ambiguous utterances. The contrasting behavior of Spanish and Palenquero negation highlights the possible role of processing mechanisms as contributing to typological differences among languages.
