However, evidence is missing with regard to Beijing 100864, China how the different functions of language and music may impact the domain specificity of congenital amusia. Pitch patterns in L.

Understanding We predicted that individuals with congenital amusia would how musical versus linguistic pitch processing in congenital perform worse than controls on both speech and song imitation amusia is affected by the nature of music and language is and that both groups would perform better on song imitation useful for formulating a model of pitch processing in music than speech imitation, due to the greater demand on pitch and language that takes into account how impairments com- precision imposed by music than speech (Patel, 2008, 2011, promise auditory-processing skills in either domain. 2012b) and because of the fact that when imitating speech Considering four theoretical perspectives, in the present study materials, individuals tend to imitate the functional goal (e.g., we examined the characteristics of pitch and rhythm process- statement/question in English) rather than the form of the ing in speech versus song imitation in individuals with con- utterances (Liu et al., 2010; Over & Gattis, 2010)unless genital amusia who speak a tone language, Mandarin. instructed to focus on pitch (Mantell & Pfordresher, 2013). The relationship between music and language Pitch/interval/contour processing in music and speech Much recent research has pointed to shared mechanisms be- Absolute pitch, interval (pitch distance between notes), and tween music and speech processing for individuals of different contour (pitch direction, up vs. down, between notes) play language and musical backgrounds (Bidelman, Gandour, & different roles in long-/short-term memory of melodies Krishnan, 2011; Hutchins, Gosselin, & Peretz, 2010;Jiang (Dowling & Bartlett, 1981; Dowling & Fujitani, 1971; et al. 2010, 2012; Liu, Jiang, et al., 2012; Liu et al., 2010; Dowling & Harwood, 1986). Previous findings suggest that Liu, Xu, et al., 2012; Mantell & Pfordresher, 2013; Nan et al., individuals with congenital amusia tended to produce pitches 2010; Patel, 2008, 2011, 2012a, 2012b; Pfordresher & Brown, lower than the targets when imitating single pitches (Hutchins, 2009; Tillmann, Burnham, Nguyen, Grimault, Gosselin & Zarate,Zatorre,&Peretz,2010),andtheyalsoshowedpitch Peretz 2011a; Tillmann, Rusconi, Traube, Butterworth, interval and contour errors in singing and pitch matching tasks Umiltà & Peretz 2011b).
