Congenital Amusia (or Tone-Deafness) Interferes with Pitch Processing in Tone Languages

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, were tested for lexical tone discrimina...

Intonation Perception Deficits in Musical Tone Deafness ( Congenital Amusia )

TO WHAT EXTENT DO MUSIC and language share neural mechanisms for processing pitch patterns? Musical tone-deafness (amusia) provides important evidence on this question. Amusics have problems with musical melody perception, yet early work suggested that they had no problems with the perception of speech intonation (Ayotte, Peretz, & Hyde, 2002). However, here we show that about 30% of amusics fr...

Disorders of Pitch Production in Tone Deafness

Singing is as natural as speaking for the majority of people. Yet some individuals (i.e., 10-15%) are poor singers, typically performing or imitating pitches and melodies inaccurately. This condition, commonly referred to as "tone deafness," has been observed both in the presence and absence of deficient pitch perception. In this article we review the existing literature concerning normal singi...

Congenital amusia in speakers of a tone language: association with lexical tone agnosia.

Congenital amusia is a neurogenetic disorder that affects the processing of musical pitch in speakers of non-tonal languages like English and French. We assessed whether this musical disorder exists among speakers of Mandarin Chinese who use pitch to alter the meaning of words. Using the Montreal Battery of Evaluation of Amusia, we tested 117 healthy young Mandarin speakers with no self-declare...
