A Destressing “Deafness” in French?

Abstract

Spanish but not French uses accent to distinguish between words (e.g., tópo vs topó). Two populations of subjects were tested on the same materials to determine whether this difference has an impact on the perceptual capacities of listeners. In Experiment 1, using an ABX paradigm, we found that French subjects had significantly more difficulties than Spanish subjects in performing an ABX classification task based on accent. In Experiment 2, we found that Spanish subjects were unable to ignore irrelevant differences in accent in a phoneme-based ABX task, whereas French subjects had no difficulty at all. In Experiment 3, we replicated the basic French finding and found that Spanish subjects benefited from redundant accent information even when phonemic information alone was sufficient to perform the task. In our final experiment, we showed that French subjects can be made to respond to the acoustic correlates of accent; therefore their difficulty in Experiment 1 seems to be located at the level of short-term memory. The implications of these findings for language-specific processing and acquisition are discussed.
