[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.

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. magnets” (Kuhl, et al., 1992), and which may arise from self-organizing perceptual maps (Guenther & Gjaja, 1996).

2009-9-21 · categories, or prototypes, function like perceptual magnets drawing the neighbouring sounds toward the prototype, thus shrinking the perceptual space around the prototype. These prototypes are language-specific and they may prevent or hinder the perceptual discrimination in their vicinity. 2001-3-16 · Guenther/Gjaja model would learn a perceptual magnet in this location. The model mimics the behavior of humans with respect to perceptual magnets in various ways, as the authors showed.

The MMN evoked potential (a preattentive, neurophysiologic index of auditory discrimination) revealed that despite equal mel differences between the stimulus pairs the MMN was largest for the prototype pair (i.e., the pair that had the lowest F 1 and highest F 2 values).

SSIM is now a widely-used perceptual video quality measure, used to test and refine video quality throughout the global cable and satellite TV industry, and

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.

It is argued that Òperceptual magnet effectsÓ (the warping of the perceptual space by prototypical exemplars of a category) can be extended to the perception of pairs of 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. 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 perceptual magnet effect, contact-induced sound change, bilingualism, speech perception, prototype theory Abstract 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. In addition, the perceptual magnet effect shows several qualitative similarities to categorical effects in perceptual domains outside of language, as vowel perception is continuous rather than sharply categorical (Fry, Abramson, Eimas, & Liberman, 1962) and the degree of category influence can vary substantially across testing conditions (Gerrits & Schouten, 2004). perceptual magnets o L1-Finnish listeners show the perceptual magnet effect for the Finnish /t/ and /tt/ categories (Heeren & Schouten, 2008) o But speakers of languages that lack (exclusively) length-based contrasts do not show any perceptual magnets along the length dimension: " no magnet for vowel tokens along the length A class of selective attention models often applied to speech perception is used to study effects of training on the perception of an unfamiliar phonetic contrast. Attention-to-dimension (A2D) models of perceptual learning assume that the dimensions that structure listeners ’ perceptual space are constant and that learning involves only the That is, no perceptual magnet effect was observed. The MMN evoked potential (a preattentive, neurophysiologic index of auditory discrimination) revealed that despite equal mel differences between the stimulus pairs the MMN was largest for the prototype pair (i.e., the pair that had the lowest F 1 and highest F 2 values).
