Mar 22, 2019 In other words, each vowel pushes the perceptual boundary away based vowels, and it is unclear if this effect can be observed in other vowels. Human adults and human infants show a “perceptual magnet effect” for t

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. 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 Keywords: perceptual magnet effect; speech perception It has long been known that categories inﬂuence percep-tion, especially in the domain of speech sounds (Liberman, Harris, Hoffman, & Grifﬁth, 1957).

perception and the perceptual magnet effect are essentially the same. For example, Lotto, Kluender, and Holt ~1998! conclude from their study that the magnet effect ‘‘may be nothing more than further demonstration that general dis-criminability is greater for cross-category stimulus pairs than for within-category pairs’’ ~p. 3648!.

Previous explanations have … The results show that individual listeners behaved differently in categorization and goodness rating but in the same way in attentive (AX) discrimination, being the poorest at about the same F2 location.

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.
