The present study investigated the existence of a ‘‘perceptual magnet’’ effect [Kuhl, Percept. Psychophys. 50, 93–107 (1991)] in a speech perception experiment.

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 … Kuhl, P. K.

Kuhl (1991) demonstrated that the perceptual magnet effect is also species-specific: Both human adults and human infants, but not rhesus monkeys, show evidence of a magnet effect. Rather, monkeys’ discrimination is determined solely by the psychophysical spacing of the vowels in the test set, suggesting the absence of any categorization.

Average generalization scores shown for stimuli surrounding the prototype and the nonprototype by adults (Experiment 2), infants (Experiment 3), and monkeys (Experiment 4). It is difficult to compare our results with previous studies of the perceptual magnet effect in English. Lively ͑1996͒ and Kuhl ͑1991͒ did not report results for specific pairs of stimuli, rather their results were collapsed across all stimuli in an orbit. A class of selective attention models often applied to speech perception is used to study effects of training on the perception of an unfamiliar phonetic contrast.

The perceptual magnet effect. Kuhl’s work [10] indicates that adult listeners’ ratings of the goodness of exemplars of a vowel vary, even while all exemplars are categorized as being the same vowel. Different exemplars of /i/ were rated by adults, and received different ratings of “goodness” (which were very consistent across raters),

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".
