'' According to Kuhl, speech prototypes act like ''magnets'' because they attract similar stimuli to themselves. Furthermore, prototypes attract other stimuli more

ABSTRACT. Recent experiments have demonstrated that the category goodness of speech sounds strongly influences perception in both adults and infants [Kuhl, Percept. Psychophys. 50, 93–107 (1991); Kuhl et al ., Science 255, 606–608 (1992)]. 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.

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. The goal of the study was to test the predictions of Kuhl's perceptual magnet effect (PME), in which perceptual distances are shrunk near good exemplars of phonetic categories and extended near poor exemplars (6-8). We hypothesized that perceived goodness would affect perceptual organization for native language categories, and The perceptual magnet effect (PME) has been investigated in conjunction with L1 vowels and consonants.

Perceptual Magnet Effect A related finding regarding statistical cues to phonological acquisition is a phenomenon known as the perceptual magnet effect.

Kuhl’s perceptual magnet effect without reporting to a specific prototype. In fact, assuming that a prototype, in Kuhl’s terms, is the center of the category distribution, the discrimination curve, discr(x0), suggests that discriminability will be lower in the neighborhood of the prototype than for stimuli falling on the main known aspects of the magnet effect, including a shrinking of perceptual space ncar phonemic category centers (Kuhl, 1991 ), an expansion of perceptual space away from centers (Kuhl, 1995), and language-specificity in this warping (Kuhl et a!., 1992). predicting perceptual effects from neural activities in this map. In Section 3, numerical simulations are used to show that the model captures the main known aspects of the magnet effect, including a shrinking of perceptual space near phonemic category centers (Kuhl, 1991), an expansion of perceptual space away The goals of this study were ~i!

The results of the musical studies have been Numerical and analytical results for the model are given, together with a brief discussion of possible other domains of application for the model. 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]). 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 According to Kuhl's (1994) Native Language Magnet (NLM) theory the phonetic perceptual space is organized in terms of prototypes.
