In order to determine the effects of variable input on the perceptual processing of sounds in Mexican and Puerto Rican Spanish, the researcher conducted experiments containing a naming task, a lexical decision task, and a dialect identification task. The most significant finding from these experiments is that the phonological variables patterned in the same way regardless of the experimental task. The participants responded most slowly to stimuli containing syllable-final /s/ in the naming and lexical decision tasks. In the identification task, the participants were most accurate at identifying the speaker dialect of stimuli containing syllable-final /s/. Thus, the realization of syllable-final /s/ seems to be a distinguishing marker of Mexican and Puerto Rican Spanish. These results are modeled within an exemplar-based model of speech perception and processing.
