“…A musical prototype can assimilate an area of approximately 25 cents in either direction (Vurma & Ross, 2006), i.e., musically trained listeners may perceive all stimuli within 25 cents of a prototype to be identical (Perlman & Krumhansl, 1996;Siegel & Siegel, 1977a). Alternatively, a prototype may show enhanced discrimination in its immediate vicinity compared to the same area surrounding a non-prototype (Acker, Pastore, & Hall, 1995;McFadden & Callaway, 1999). Neither of these effects must necessarily occur, even among trained listeners (Schellenberg, 2002); however, it may be that with increasing musical experience, a prototype gradually changes from magnet to anchor, as detecting fine mistunings becomes more important to professional performance (Barrett, 1999).…”
