The magnet effect is observed when tokens perceived as exceptionally good representatives of a phonetic category (“prototypes”) are used in tests of speech perception ( 63 – 66 ). Perceptual Magnet Effect A related finding regarding statistical cues to phonological acquisition is a phenomenon known as the perceptual magnet effect. [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. ﬁnding has been termed the Perceptual-Magnet Effect~PME; see Kuhl, 1991, 1993; Kuhl et al., 1992!. Kuhl ~1991! sug-gests that the prototype ~judged as best representative! vowel acts as a magnet drawing in vowel exemplars and increasing similarity between the magnet and other members of the cat-egory.

The perceptual magnet effect is a phenomenon that recent investigations reveal problematic (Lively & Pisoni, 1997; Lotto, Kluender, & Holt, 1998). According to Kuhl (1991), a magnet effect occurs when discrimination around the best exemplar of a phonetic category is worse than discrimination around a poor exemplar of the category. Kuhl’s perceptual magnet effect without reporting to a specific prototype. In fact, assuming that a prototype, in Kuhl’s terms, is the center of the category distribution, the discrimination curve, discr(x0), suggests that discriminability will be lower in the neighborhood of the prototype than for stimuli falling on the main known aspects of the magnet effect, including a shrinking of perceptual space ncar phonemic category centers (Kuhl, 1991 ), an expansion of perceptual space away from centers (Kuhl, 1995), and language-specificity in this warping (Kuhl et a!., 1992).

Given that the magnet effeet is argued to be a result of experience with sounds, the effect should generalize to nonspeech, musical stimuli. The results of the musical studies have been (Kuhl et al., 1992) as well as MMN (Cheour et al., 1998; Kuhl & Coffey-Corina, 2001), have demonstrated that infants exhibit language-speciﬁc perceptual sensitivities for phonetic units between 6 and 12 months of age, prior to the age that word meanings are thought to be acquired.

A basic assumption of the NLM theory is that perceptual space is partitioned into phonetically relevant categories that are represented by category prototypes the category's "best exemplar". The category prototypes function as “perceptual magnets” that attract exemplars falling 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.

Linguistic expe- rience and the ”Perceptual Magnet Effect”. I: W. Strange (red.), Speech Perception and sala: Hallgren & Fallgren. Kuhl, P. K. & Iverson, P. (1995). Linguistic expe- rience and the ”Perceptual Magnet Effect”.

The goal of the study was to test the predictions of Kuhl's perceptual magnet effect (PME), in which perceptual distances are shrunk near good exemplars of phonetic categories and extended near poor exemplars (6-8). We hypothesized that perceived goodness would affect perceptual organization for native language categories, and cognitive psychology. Kuhl (1995) proposes a native language magnet (NLM) model of infant perceptual development that includes an account of the magnet effect. Kuhl’s account assumes that a phonetic “proto-type” for each sound category exists in memory and plays a unique role in speech perception: it functions 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. perceptual space.
