(Lacerda, 1995). The term perceptual magnet effect refers to the perceptual phenomenon of sensitivity minima near best exemplars, and the exact cause of the perceptual mag-net effect is unknown. Empirical Distinctions Research on the perceptual magnet effect has primar-ily been concerned with establishing the correlation be- As with the phoneme boundary effect, the perceptual magnet effect has been strongly linked to a hypothesized mechanism; the perceptual magneteffecthas been seen to imply that pho­ neme categories are represented in terms ofprototypes (i.e., a single abstract exemplar that represents all the members ofacategory) and that phonemes are at least par­ tially perceived in terms oftheir distance from these pro­ totypes. The perceptual magnet effect describes an increased generalization capability for the perception of vowels, if the perceived vowels are prototypical. 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.

Linguistic areas are geographic regions where languages share characteristics as a result of language contact and not as a consequence of shared inheritance, general linguistic tendencies, linguistic universals, or chance.1 Though there 2016-1-1 · The phoneme categories that result from this tuning process can be thought of as “attractor states” (Damper & Harnad, 2000) or “perceptual magnets” that “pull” the neural activity pattern toward a target position in phoneme perceptual space regardless of small variations in the acoustic input. The NLM theory predicts that the perceptual space is warped in the neighborhood of these perceptual magnets because a prototype attracts exemplars that fall within its zone of influence. The present paper introduces a very simple theoretical model that accounts for the perceptual-magnet effect as an emergent consequence of an exemplar-based phonetic memory. Perceptual learning about speech is thus constrained by spectral similarity between the input and established phonological categories, but within those limits, adjustments are thorough enough that even nonnative sounds can be treated fully as native sounds. (Show Context) Powered by: Phonetic category prototypes function like "perceptual magnets" for other stimuli in the category.

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 between dif-ferent instances of a given category. During speech perception, perceived instances of a category are stored in the perceptual space of the listener.

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.

Perceptual magnets

The results demonstrated that sensitivity peaks at vowel boundaries were more influenced by stimulus range than were perceptual magnet effects; peaks in sensitivity near the /i/-/e/ boundary were reduced with restricted stimulus ranges and one-step intervals, but nüfüma in discrimination near the best exemplars of /i/ were present in all conditions. was that infants would show a ‘perceptual magnet effect’for native-language sounds,because prototypical sounds function like magnets for surrounding sounds 42.

[14] [15] [16] 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. You can learn more about CuriosityStream at out the new Space Time Merch Store! Sp Kuhl’s native language magnet (NLM) theory of phonetic learning is examined in the light of an exemplar-based model. According to the NLM theory the perceptual space is partitioned into phonetic categories as a consequence of the magnet-like properties of the category’s best exemplar the category’s prototype.
