We give a local version of it, where the similarity between two events The “Perceptual Magnet” Effect: A Model Based on Self-Organizing Feature Maps. In Smith LS, Hancock PJB, editors, Neural Computation and Psychology: Proceedings of the 3rd Neural Computation and Psychology Workshop (NCPW3), Stirling, Scotland, 31 August -- 2 September 1994. perceptual magnet effect, namely an identiﬁcation test, a good-ness rating task and a discrimination test. The tests had to be performed in this order because the results of the identiﬁcation render the input stimuli for the goodness rating, and the results of the goodness rating render the input stimuli for the discrim-ination.

The effect is characterized by a warping of perceptual space near phonemic category effect is present in 6-month-old infants, the magnet effect is sensitive to early linguistic experience, monkeys tested with the same technique fail to provide evidence of a perceptual magnet 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.

The goal of listen-ers is to classify sounds into phonetic categories; perception involves retrieving a set of numerical values that reﬂect the sound’ssimilarityto each phonetic category in a language. The notion of a perceptual magnet was introduced. The prototype of the category functioned like a perceptual magnet for other category members; it assimilated neighboring stimuli, effectively pulling them toward the prototype.

When we think of a region, it describes a common area that shares different characteristics. These characteristics can either be physical or cultural. For example, we can group regions by climate or physical geography such as landforms and Simply put, magnetic energy is the energy that operates within a magnetic field. A magnetic field is invisible to the naked eye, but that does mean that the effects of magnetic energy are not felt.

Second, previous data from our lab had shown that infants correctly categorize perceptually diverse instances of hi! vowels, ones spoken by men, women, and children (Kuhl, 1979; KuhI, 1985a, for review). The perceptual magnet effect is one of the earliest known language-specific phenomena arising in infant speech development.

107-116. Discrimination experiments suggest a nonlinear relationship between acoustic and perceptual space near category centers (Iverson & Kuhl, 1995b). This phenomenon has been described as theperceptual magnet effect. The present study investigated the presence of the perceptual magnet effect in five Australian vowel categories.

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

“perceptual-magnet” that exerts its attraction force on neighboring auditory representations [7]. Stimuli producing auditory representations in that neighborhood are attracted to the prototype. In contrast, non-prototypical sounds are not supposed to exhibit the magnetic effect. In other words, discrimination, as a function of the 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 Linguistic experience and the ‘perceptual magnet effect’. (1995) by P K Kuhl, P Iverson Venue: Speech perception and linguistic experience. Timonium, Add To The notion of aperceptual magnet was introduced.

Perceptual magnet effect in the light of behavioral and psychophysiological data Olli Aaltonen Centre for Cognitive Neuroscience and Department of Phonetics, University of Turku, FIN-20014 Turku, Finland Osmo Eerola Centre for Cognitive Neuroscience, University of Turku, FIN-20014 Turku, Finland A˚ke Hellstro¨m Department of Psychology, Stockholm University, S-106 91 Stockholm, Sweden and Previous research has demonstrated an apparent warping of the perceptual space whereby the best exemplars or ‘prototypes’ of speech sound categories minimize the perceptual distance between themselves and neighboring stimuli in the same category. 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.
