introduction of the perceptual-magnet notion extends the traditional view of prototype-based classification processes by accounting for non-linear effects. Nevertheless a prototype-based approach raises issues that are rooted in the very notion of prototype. One issue, for instance, concerns its application to The Perceptual Magnet Effect (PME) is such evidence of categoricalness [9], [10]. PME is a pair of experimentally-observable "symptoms" that result from the presence of the internal structure of categories, e.g. colours and sounds. The first symptom is that the variability in density and activation of exemplars Abstract and Figures Previous research has demonstrated an apparent warping of the perceptual space whereby the best exemplars or ‘prototypes’ of speech sound categories minimize the perceptual Human adults and human infants show a ‘perceptual magnet effect’ for the prototypes of speech categories, monkeys do not.

The perceptual magnet effect is hypothesized to reflect prototype learning in cognitive psychology 43. speech sounds despite such changes 19–23.By co ntrast, An additional finding that makes claims of a perceptual magnet effect questionable is the failure of experiments utilizing musical stimuli to find the effect (e.g., Aeker, Pastore, & Hall, 1995; Schellenberg, 2002).

[14] [15] [16] In this effect, a prototypical phoneme of a person's native language acts as a “magnet” for similar phonemes, which are perceived as belonging to the same category as the prototypical phoneme.

According to the NLM theory the perceptual space is partitioned into phonetic categories as a consequence of the magnet-like properties of the category’s best exemplar the category’s prototype.

The present paper introduces a very simple theoretical model that accounts for the perceptual-magnet effect as an emergent consequence of an exemplar-based phonetic memory.

Best's perceptual assimilation model (PAM) and Kuhl's native language magnet model (NLM) were proposed to explain general and language-specific perception of speech sounds. PAM provides a “direct realist” account of native and nonnative speech perception, in which infants perceive speech categorically by recovering information about the speaker's vocal tract configuration.

The present study used the methodology of Iverson and Kuhl [P. Iverson and P. K. Kuhl, J. Acoust. Soc. Am. 99, 1130-1140 (1996)] to examine whether Japanese speakers who have had exposure to English Moreover, the perceptual magnet effect depends on exposure to a specific language . Six-month-old infants being raised in the United States and Sweden were tested with two vowel prototypes, an American English /i/ vowel prototype and a Swedish /y/ vowel prototype, using the exact same stimuli (Fig. 5 A ), techniques, and testers in the two countries. This widening of the “bin” for frequencies perceived as A can be likened to a perceptual magnet effect previously described for speech (18, 19).
