"743","A limit on behavioral plasticity in speech perception.","It is well attested that we perceive speech through the filter of our native language: a classic example is that of Japanese listeners who cannot discriminate between the American /l/ and /r/ and identify both as their own /r/ phoneme (Goto, 1971). Studies in the laboratory have shown, however, that perception of non-native speech sounds can be learned through training (Lively, Pisoni, Yamada, & Tohkura, 1994). This is consistent with neurophysiological evidence showing considerable experience-dependent plasticity in the brain at the first levels of sensory processing (Edeline & Weinberger, 1993; Kraus, et al., 1995; Merzenich & Sameshima, 1993; Weinberger, 1993). Outside of the laboratory, however, the situation seems to differ: we here report a study involving Spanish-Catalan bilingual subjects who have had the best opportunities to learn a new contrast but did not do it. Our study demonstrates a striking lack of behavioral plasticity: early and extensive exposure to a second language is not sufficient to attain the ultimate phonological competence of native speakers.","http://cogprints.org/743/","Pallier, C. and Bosch, L. and Sebastian-Gallés, N.","UNSPECIFIED","       <span class=\"person_name\">Pallier, C.</span> and <span class=\"person_name\">Bosch, L.</span> and <span class=\"person_name\">Sebastian-Gallés, N.</span>     (1997)  <a href=\"http://cogprints.org/743/\"><em>A limit on behavioral plasticity in speech perception.</em></a>       [Journal (Paginated)]           ","","1997-09"
