In three experiments, we explore the effects of phonological properties such as neighbourhood density and frequency on speech production in Spanish. Specifically, we assess the reliability of the recent observation made by Vitevitch and Stamer (2006), according to which the neighbourhood effect in Spanish has a reverse polarity to that observed in…

Atypical vocabulary has been reported as one of the most notable features of the language of adolescents and adults with Williams syndrome (WS), including use of unusual or low frequency words. Two hypotheses were identified regarding the developmental origins of this phenomenon. The "intra-lexicon" hypothesis views the cause in terms of…

Current models of spoken-word recognition describe access to lexical representations in terms of activation and decay. This research investigated an important aspect of activation: the impact of processing time. The results showed a separable impact of time and signal on the activational state of lexical elements.
