Design of a corpus of stimuli for a psycholinguistic study of lexical ambiguity

Abstract

Lexical ambiguity takes place when a word has more than one meaning. This phenomenon could therefore lead to multiple difficulties in the processing of information; however, speakers deal almost effortlessly with ambiguous units on a daily basis. In order to understand how ambiguous items are processed by speakers, a clear synchronic definition of homonymy and polysemy is needed. In this paper a methodology to gather subjective information about ambiguous words and the relation within their meanings is proposed. Based on this methodology, a corpus of Spanish stimuli is being developed: this corpus consists of words classified as monosemic, homonymous and polysemous via the subjective interpretation of Spanish speakers. This corpus could be used to conduct experimental tasks to determine the behaviour in on-line processing of items with more than one meaning, in order to later design appropriate methods of approaching this complex phenomenon from the point of view of Psycholinguistics.
