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.

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,

an attractor effect on surrounding sounds in the same speech category, making it difficult to tell the difference between the prototype and acoustically-similar sounds (e.g. Iverson & Kuhl, 1995; Kuhl 1991). This has been called the perceptual magnet effect (Kuhl, 1992) and it has been used to account for one of the most fundamental

Descriptions of categorical effects in vowels have focused primarily on the perceptual magnet effect (Kuhl, 1991). This effect was originally proposed as a within-category phe-nomenon, characterized by sounds near category centers be-ing more difficult to discriminate than sounds near cate-gory edges, with an accompanying correlation between good- Kuhl et al. 1992 \Linguistic Experience Alters Phonetic Perception in Infants by 6 Months of Age" (Science, 1992) main nding: perceptual magnet e ect is con rmed location of prototypes depends on native language e ect can be observed already with infants in pre-linguistic age comparison of American (native language: AE) and Swedish infants 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 (Kuhl et al., 1992) as well as MMN (Cheour et al., 1998; Kuhl & Coffey-Corina, 2001), have demonstrated that infants exhibit language-specific perceptual sensitivities for phonetic units between 6 and 12 months of age, prior to the age that word meanings are thought to be acquired.

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).

one such phenomenon, the perceptual magnet effect (Kuhl, 1991), which has been described primarily in vowels. The perceptual magnet effect involves reduced discriminability of speech sounds near phonetic category prototypes. For several reasons, speech sounds, particularly vowels, provide an excellent starting point for The perceptual magnet effect (PME) has been investigated in conjunction with L1 vowels and consonants. However, there has been a paucity of examinations of the effect in L2 speech perception. The present study used the methodology of Iverson and Kuhl [P.

Both groups of infants demonstrated a perceptual magnet effect - "Human adults and human infants show a “perceptual magnet effect” for the prototypes of speech categories, monkeys do not" Figure 5. Average generalization scores shown for stimuli surrounding the prototype and the nonprototype by adults (Experiment 2), infants (Experiment 3), and monkeys (Experiment 4). It is difficult to compare our results with previous studies of the perceptual magnet effect in English. Lively ͑1996͒ and Kuhl ͑1991͒ did not report results for specific pairs of stimuli, rather their results were collapsed across all stimuli in an orbit. A class of selective attention models often applied to speech perception is used to study effects of training on the perception of an unfamiliar phonetic contrast. Attention-to-dimension (A2D) models of perceptual learning assume that the dimensions that structure listeners ’ perceptual space are constant and that learning involves only the The perceptual magnet effect (Kuhl, I 991) is one of the most actively discussed topics in the recent speech perception literature (e.g., Davis and Kuhl, I 994; Fox, Flege, and Munro, I 995; Iverson, Diesch, Siebert, and Kuhl, I 994; Iverson and Kuhl, I 994, I 995; Perceptual Magnet Effect A related finding regarding statistical cues to phonological acquisition is a phenomenon known as the perceptual magnet effect.
