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.

However, one possible confound is that category membership is determined by identification of 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 a model in which the perceptual magnet effect emerges as a side-effect of a classiﬁcation problem.

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.

Previous explanations have been formulated within the theoretical framework of cognitive psychology. 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).

Recent auditory research has raised fundamental questions about the perceptual magnet effect (PME), where discrimination performance is poorer for stimuli that approach best exemplars of a phonetic category. It has been suggested that the effect reflects inter-categorical comparisons, and might not generalize to nonspeech. Three experiments addressed these concerns.

(1995) by P K Kuhl, P Iverson Venue: Speech perception and linguistic experience. Timonium, Add To The notion of aperceptual 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. In Experiment 3, the ontogenetic origins of the perceptual magnet effect were explored by testing 6-month-old infants. The "perceptual magnet" effect: A model based on self-organizing feature maps J.

1995-01-01 The goals of this study were (i) to assess the replicability of the 'perceptual magnet effect' [Iverson and Kuhl, J. Acoust. Soc. Am. 97(1), 553- 561 (1995)] and (ii) to investigate neurophysiologic processes underlying the perceptual magnet effect by using the mismatch … 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.
