KUHL University of Washington, Seattle, Washington Many perceptual categories exhibit internal structure in which category prototypes play an important role.

The category prototypes function as “perceptual magnets” that attract exemplars falling recently, however, Kuhl and colleagues have found evidence of poor discrimination near phonetic category prototypes, a phenomenon they have called the perceptual magnet effect based on the idea that native language prototypespullneigh-boringspeech soundstowardthem(Kuhl, Williams,Lacerda, Stevens, & Lindblom,1992;butsee Lotto,Kluender, & Holt, Psychophys. 50, 93-107 (1991); Kuhl et al., Science 255, 606-608 (1992)]. Stimuli judged as exceptionally good instances of phonetic categories (prototypes) make neighboring tokens in the vowel The question of whether sensitivity peaks at vowel boundaries (i.e., phoneme boundary effects) and sensitivity minima near excellent category exemplars (i.e., perceptual magnet effects) stem from the same stage of perceptual processing was examined in two experiments.
