Selective attention and English listeners' perceptual learning of the Polish post-alveolar sibilant contrast
This study reports data from a series of training experiments exploring the warping of perceptual space due to the acquisition of phonetic categories by adults. In this study, subjects were trained to categorize a highly naturalistic consonant place distinction in a two-dimensional sibilant fricative + vowel stimulus set varying by fricative and vocalic information. Subjects were trained to use...
متن کاملDichoptic color saturation mixture: Binocular luminance contrast promotes perceptual averaging.
We demonstrate a new type of interaction between suprathreshold color (chromatic) and luminance contrast in the context of binocular vision. When two isoluminant colored disks of identical hue but different saturations are presented to different eyes, the apparent saturation of the resulting "dichoptic" mix is close to that of the more saturated patch if presented binocularly. This result is co...
متن کاملIs color "categorical perception" really perceptual?
Roberson and Davidoff (2000) found that color categorical perception (CP; better cross-category than within-category discrimination) was eliminated by verbal, but not by visual, interference presented during the interstimulus interval (ISI) of a discrimination task. On the basis of this finding, Roberson and Davidoff concluded that CP was mediated by verbal labels, and not by perceptual mechani...
متن کاملPerceptual Learning of Contrast Detection in the Human Lateral Geniculate Nucleus
The brain is continuously modified by perceptual experience throughout life. Perceptual learning, which refers to the long-term performance improvement resulting from practice, has been widely used as a paradigm to study experience-dependent brain plasticity in adults [1, 2]. In the visual system, adult plasticity is largely believed to be restricted to the cortex, with subcortical structures l...
متن کاملMechanisms underlying perceptual learning of contrast detection in adults with anisometropic amblyopia.
What underlies contrast sensitivity improvements in adults with anisometropic amblyopia following perceptual learning in grating contrast detection? In this paper, we adopted the external noise approach (Z.-L. Lu & B. A. Dosher, 1998) to identify the mechanisms underlying perceptual learning in adults with anisometropic amblyopia. By measuring contrast thresholds in a range of external noise co...
