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 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.

The perceptual phenomenon of the occurrence of poor sensitivity near best exemplars has been called the per-ceptual magnet effect (Kuhl, 1991); the perceptual space is shrunk near best exemplars, effectively drawing neighbor-ing stimuli toward best-exemplar locations.

A noteworthy feature of a The perceptual magnet effect is one of the earliest known language-specific phenomena arising in infant speech development. The effect is characterized by a 23 Feb 2007 she calls "perceptual magnets". By conducting a series of experiments, she provides convincing evidence that vowel categories are structured 30 May 2019 The perceptual magnet effect as an emergent property of neural map formation.

They concluded that these perceptual magnets.In this study, we examined the discriminability of the English (non-German) / /–/ æ/ contrast and the German (non-English) /u/–/y/ contrast by 6–8 and 10–12 month-old German-and English-learning infants. 2 We expected to observe perceptual asymmetries in discrimination of the non-native but not native contrasts.This LING 696B: Categorical perception, perceptual magnets and neural nets - LING 696B: Categorical perception, perceptual magnets and neural nets From last time: quick overview of phonological acquisition Prenatal to newborn 4-day-old French 2020-1-13 · native language function as “perceptual magnets” or “attractors,” causing acoustically similar tokens to be perceived as members of the same linguistic category [Kuhl, 1991; Kuhl, Iverson, 1995]. The acquisition of new speech sounds occurs on the background of the distribution of prototypes in acoustic/perceptual space. 2017-3-14 · perceptual magnets found in the input data, relying solely on facts about token distributions. That is, if the input set of formant frequencies has a cluster that centers loosely on the phonetic target for (say) [i], the Guenther/Gjaja model would learn a perceptual magnet in this location. 2019-8-2 · phones that act as perceptual magnets. These magnets attract perceptually similar non-native phones, affecting the formation of accurate L2 categories.

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. The perceptual magnet effect involves reduced discriminabil-ity near prototypicalvowel sounds in the native language. We presenta Bayesianmodeltoexplainwhythisreduceddiscrim-inabilitymight occur: it arises as a consequence of optimally solvingthe statistical problem of perceiving speech sounds in the presence of noise.
