Is discrimination enhanced at the boundaries of perceptual categories? A negative case.
The human visual system imposes discrete perceptual categories on the continuous input space that is represented by the ratios of excitations of the cones in the retina. Is discrimination enhanced at the boundaries between perceptual hues, in the way that discrimination may be enhanced at the boundaries between speech sounds in hearing? In the chromaticity diagram, the locus of unique green sep...
متن کاملEnhanced discriminability at the phonetic boundaries for the place feature in macaques.
Discrimination of speech-sound pairs drawn from a computer-generated continuum in which syllables varied along the place of articulation phonetic feature (/b,d,g/) was tested with macaques. The acoustic feature that was varied along the two-formant 15-step continuum was the starting frequency of the second-formant transition. Discrimination of stimulus pairs separated by two steps was tested al...
متن کاملEnhanced discriminability at the phonetic boundaries for the voicing feature in macaques.
DiacrimiDation of apeech IOUDda from three computer-pnerated continua that ranged from volced to voiceleessyllables (/be.paI, Ida·taI, and Ip·bI) was tested with three macaques. The stimuli on .ch continuum varied in voice-onset time (VOT). Pain of stimuli that were equally different in VOT were chosen such that they were either withln-eategory pairs (syllables given the same phonetic label by ...
متن کاملThe discrimination of speech sounds within and across phoneme boundaries.
In listening to speech, one typically reduces the number and variety of the many sounds with which he is bombarded by casting them into one or another of the phoneme categories that his language allows. Thus, a listener will identify as b, for example, quite a large number of acoustically different sounds. Although these differences are likely to be many and various, some of them will occur alo...
متن کاملLateralization of phonetic and pitch discrimination in speech processing.
Cerebral activation was measured with positron emission tomography in ten human volunteers. The primary auditory cortex showed increased activity in response to noise bursts, whereas acoustically matched speech syllables activated secondary auditory cortices bilaterally. Instructions to make judgments about different attributes of the same speech signal resulted in activation of specific latera...
