The Perceptual Magnet Effect as an Emergent Property of Neural Map Formation Frank H. Guenther and Marin N. Gjaja Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems 677 Beacon Street Boston, MA, 02215 Fax Number: (617) 353-7755 email: guenther@cns.bu.edu, gjaja@cns.bu.edu Previous research has demonstrated an apparent warping of the perceptual space whereby the best exemplars or ‘prototypes’ of speech sound categories minimize the perceptual distance between themselves and neighboring stimuli in the same category. This phenomenon has been termed the ‘perceptual magnet effect’ (PME). In recent years there has been a great deal of interest in demonstrations of the so-called 'Perceptual-Magnet Effect' (PME). In these studies, AX-discrimination tasks purportedly reveal that discriminability of speech sounds from a single category varies with judged phonetic 'goodness' of the sounds. claimed shrinking of perceptual space around prototypes has been termed the perceptual magnet effect (see Kuhl, 1991). This effect, if reliable, has important implications for how we categorize speech information.

The term perceptual magnet effect refers to the perceptual phenomenon of sensitivity minima near Stimuli judged as exceptionally good instances of phonetic categories (prototypes) make neighboring tokens in the vowel space seem more similar, exhibiting a perceptual magnet effect. Three 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.
