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. This paper takes the alternative approach of looking for evidence of structure within a postulated category by testing for a Perceptual Magnet Effect (PME).

The perceptual magnet effect involves reduced discriminability of speech sounds near phonetic category prototypes. For several reasons, speech sounds, particularly vowels, provide an excellent starting point for CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The perceptual magnet effect describes an increased generalization capability for the perception of vowels, if the perceived vowels are prototypical. perceptual magnet effect Michael C.

Stern will present work from the SLA Lab at the 27th Manchester Phonology Meeting on perceptual magnet effects in monolingual and bilingual perception. The perceptual magnet effect ~PME! reported by Kuhl ~1991! has been a hotly debated topic in the speech percep-tion literature in recent years. According to the Kuhl et al.

Studies currently being conducted on additional cues to velar stop goodness will also be discussed. [Work supported by NIH.] © 1994 Acoustical Society of America.

The term perceptual magnet effect refers to the perceptual phenomenon of sensitivity minima near The perceptual magnet effect describes an increased generalization capability for the perception of vowels, if the perceived vowels are prototypical. 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. a model in which the perceptual magnet effect emerges as a side-effect of a classiﬁcation problem. 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.
