und 4. Discrimination experiments suggest a nonlinear relationship between acoustic and perceptual space near category centers (Iverson & Kuhl, 1995b). This phenomenon has been described as the perceptual magnet effect. The present study investigated the presence of the perceptual magnet effect in five Australian vowel categories. The perceptual magnet effect (PME) has been investigated in conjunction with L1 vowels and consonants.
1 "Perceptual magnet" effect In human adults and infants the discriminability of vowels has been found to depend on the degree of typicality of the vowels within their respective phonetic category (perceptual magnet effect, [1]). Our ability to discriminate sounds is not uniform throughout acoustic space. One example of auditory space warping, termed the perceptual magnet effect by Kuhl and colleagues, appears to arise from exposure to the phonemes of an infant's native language. We have developed a neural model that accounts for the magnet effect in terms of neural map dynamics in auditory cortex. This model predicts http://www.ted.com At TEDxRainier, Patricia Kuhl shares astonishing findings about how babies learn one language over another -- by listening to the humans a 16 Oct 2020 The perceptual magnet effect was indicated in the good categorizers both by guage.

The perceptual magnet effect manifests itself by 6 months of age (Kuhl, 1991, 2001).

A basic assumption of the NLM theory is that perceptual space is partitioned into phonetically relevant categories that are represented by category prototypes the category's "best exemplar". The category prototypes function as “perceptual magnets” that attract exemplars falling Psychophys. 50, 93-107 (1991); Kuhl et al., Science 255, 606-608 (1992)].
The present study investigated the presence of the perceptual magnet effect in five Australian vowel categories. 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. Iverson and P. K. Kuhl, J. Acoust. Soc. Am. 99, 1130-1140 (1996)] to examine whether Japanese speakers who have had exposure to English

Given that the magnet effeet is argued to be a result of experience with sounds, the effect should generalize to nonspeech, musical stimuli. The results of the musical studies have been
