In Experiment 1, participants g … The present study investigated the existence of a ‘‘perceptual magnet’’ effect [Kuhl, Percept. Psychophys. 50, 93–107 (1991)] in a speech perception experiment. Sixteen subjects experienced in phonetics, transcribed the [i] stimuli used by Kuhl (1991) or identified the stimuli as [i] or not‐[i] in experiment 1. In experiments 2 and 3, 50 adults who were not trained in phonetics 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.

Once a sound category exists in memory,. 'perceptual magnet effect' [Kuhl, 1991]: a perceptual distortion around a phonetic prototype. The Native Language Magnet. Model maintains that exposure to a category by testing for a Perceptual Magnet Effect (PME). PME has been [9] P. K.

The results demonstrate that the / i / /e / identification boundary was located near Stimulus 10 and that the best exemplar of the / i / category was located near Stimulus 2. None was a good exemplar of the /e / category. - "Perceptual magnet and phoneme boundary effects in speech perception: Do they arise from a common mechanism?"

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-

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. Three experiments further examined the perceptual magnet effect in adults.

We here propose an unsupervised, adaptive neural network model which allows to control the relation between stimulus density and generalization capability, and which can AUTHOR Kuhl, Patricia K. TITLE Infants' Perception and Representation of Speech: Development of a New Theory.

Recent experiments have demonstrated that category goodness influences the perception of vowels [Iverson and Kuhl, J. Acoust. Soc.

Kuhl’s work [10] indicates that adult listeners’ ratings of the goodness of exemplars of a vowel vary, even while all exemplars are categorized as being the same vowel. Different exemplars of /i/ were rated by adults, and received different ratings of “goodness” (which were very consistent across raters), 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. Perceptual Magnet Effect A related finding regarding statistical cues to phonological acquisition is a phenomenon known as the perceptual magnet effect.
