The perceptual magnet effect is a phenomenon that recent investigations reveal problematic (Lively & Pisoni, 1997; Lotto, Kluender, & Holt, 1998). According to Kuhl (1991), a magnet effect occurs when discrimination around the best exemplar of a phonetic category is worse than discrimination around a poor exemplar of the category. Recent experiments have demonstrated that category goodness influences the perception of vowels [Iverson and Kuhl, J. Acoust. Soc. Am. 97, 553-562 (1995)]; listeners show a perceptual magnet effect characterized by shrunken perceptual distances near excellent exemplars of vowel categories and stretc … was that infants would show a ‘perceptual magnet effect’for native-language sounds,because prototypical sounds function like magnets for surrounding sounds 42.

Like the explanations of Kuhl and Lacerda, the current model assumes that the magnet effect is related to the distribution of speech sounds experienced by an infant in the first stages of life.

This effect appears to arise due to linguistic experience, since 6-month-old American babies show the effect for an American vowel but not a Swedish vowel, and Swedish babies show the opposite effect (Kuhl et al., 1992). We have developed, experimentally tested, and refined a neural model that explains the perceptual magnet effect

The Native Language Magnet Theory (NLM) (Kuhl, et al. 2008) holds that infants categorize sound patterns into a “sound map.” By 6-months, an English-speaking infant has heard hundreds of thousands of examples of the /i/ as in “daddy” and “mommy,” and NLM claims babies develop a sound map in their brains that helps them hear the /i/ sound clearly. native language magnet theory expanded (NLM-e).
