Second, previous data from our lab had shown that infants correctly categorize perceptually diverse instances of hi! vowels, ones spoken by men, women, and children (Kuhl, 1979; KuhI, 1985a, for review). 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 cogn … 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 “perceptual-magnet” that exerts its attraction force on neighboring auditory representations . Stimuli producing auditory representations in that neighborhood are attracted to the prototype.

Session Title: 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.

Perceptual Magnet Effect • Der Prototyp zieht umliegende Laute an/zu sich heran und macht sie schwerer differenzierbar (--> Magnet ) • Non-prototypes zu differenzieren ist dann einfacher -> Sie richten sich an den Rändern der Kategorie aus -> Sie unterliegen dem Anziehungseffekt nicht
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). 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.
