The perceptual magnet effect is one of the earliest known language-specific phenomena arising in infant speech development. The effect is characterized by a warping of perceptual space near phonemic category centers. Previous explanations have been formulated within the theoretical framework of cognitive psychology.

1.2. Testing the perceptual magnet effect (PME) Discrimination differences also inside the obtained categories were reported in [5]. These results appear to be more com-patible with the concept of a perceptual magnet effect (PME) introduced by Kuhl [7] rather than with CP.

Previous explanations have … The results show that individual listeners behaved differently in categorization and goodness rating but in the same way in attentive (AX) discrimination, being the poorest at about the same F2 location. The perceptual magnet effect was indicated in the good categorizers both by behavioral and psychophysiological (MMN) discrimination data.

This phenomenon has been termed the ‘perceptual magnet effect’ (PME). In recent years there has been a great deal of interest in demonstrations of the so-called 'Perceptual-Magnet Effect' (PME). In these studies, AX-discrimination tasks purportedly reveal that discriminability of speech sounds from a single category varies with judged phonetic 'goodness' of the sounds.

In Speech perception and linguistic experience: Theoretical and methodological issues  Perceptual Magnet Effect The Perceptual Magnet Effect is a phenomenon by which sounds which are “surrounding” a phonemic category are “perceptually  exists for humans; also known as the Native Language Magnet (NLM). The perceptual magnet effect manifests itself by 6 months of age (Kuhl, 1991, 2001).

The perceptual magnet effect describes an increased generalization capability for the perception of vowels, if the perceived vowels are prototypical. We here propose an unsupervised, adaptive neural network model which allows to control the relation between stimulus density and generalization capability, and which can account for the perceptual magnet effect.

Testing the perceptual magnet effect (PME) Discrimination differences also inside the obtained categories were reported in [5]. These results appear to be more com-patible with the concept of a perceptual magnet effect (PME) introduced by Kuhl [7] rather than with CP. According to [7], language acquisition warps the perceived distances Two experiments demonstrate that the perceptual magnet effect is context sensitive. In experiment 1a, 24 participants rated goodness of synthetic /u/ in isolation (ooh) and in two consonantal contexts, /lu/, /ju/ (Lou, you), with nine versions per word, varying in F2 frequency. Their most (prototypical) and least (nonprototypical) preferred choices reflected expected differences between words That is, no perceptual magnet effect was observed.

Paris 6, UMR 7102 F75005, Paris, France romain.brasselet@upmc.fr ABSTRACT In this paper, we propose an extension of the recently introduced metrical information [1]. We give a local version of it, where the similarity between two events PERCEPTUAL MAGNET EFFECT FOR SPEECH PROTOTYPES 95 asserts that these three vowels are acoustically more stabile than other vowels.

PERCEPTUAL MAGNET EFFECT 875 arise because of experience-related distortions in auditory processing (Guenther & Gjaja, 1996) or because of cate-gorization processes based on multiple stored exemplars (Lacerda, 1995). The term perceptual magnet effect refers to the perceptual phenomenon of sensitivity minima near 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 The question of whether sensitivity peaks at vowel boundaries (i.e., phoneme boundary effects) and sensitivity minima near excellent category exemplars (i.e., perceptual magnet effects) stem from the same stage of perceptual processing was examined in two experiments.
