This reasoning led to the Native Language Magnet model of speech perception (early 1990s onwards, see Pickett p249-255). Recent extension: Kuhl (2007) But: what is a “phonetic category” Kuhl is inexplicit, but implies it’s a phoneme. • But phonemes can’t be directly related to psychoacoustic space… • …and phones vary a lot in different contexts. Barrett (1997): (PhD thesis, CU Linguistics Dept) • magnet effects are context-sensitive: /u lu ju/ have independent prototypes & magnet effects • magnet effects differ depending on function: musicians have enhanced discrimination around C major chord, non-musicians do not, but can be trained to. So phonetic prototypes, demonstrated by perceptual magnet effects, operate at unknown and possibly more than one level of abstraction, and may serve various different purposes. • Do they involve memories of good/common patterns (cf. semantics) • Should we consider them as task-dependent functional processes
