Congenital amusia is a neurogenetic disorder that affects music processing and that is ascribed to a deficit in pitch processing. We investigated whether this deficit extended to pitch processing in speech, notably the pitch changes used to contrast lexical tones in tonal languages. Congenital amusics and matched controls, all non-tonal language speakers,(More)
Here we present evidence that native speakers of a tone language, in which pitch contributes to word meaning, are impaired in the discrimination of falling pitches in tone sequences, as compared to speakers of a non-tone language. Both groups were presented with monotonic and isochronous sequences of five tones (i.e., constant pitch and intertone interval).(More)
Twenty amusic and 20 control speakers of French were presented with pairs of Mandarin lexical tones to discriminate as same or different. Results revealed that even if the amusic group performed significantly below the control group, the scores of the two groups largely overlapped, with only 15% of the amusic group performing outside the normal variations.(More)
