The Derived Allele of ASPM Is Associated with Lexical Tone Perception

Science 309; Evans P.D. et al., 2005. Microcephalin, a gene regulating brain size, continues to evolve adaptively in humans. Science 309]. Curiously, experimental attempts have failed to connect th...

The visual perception of lexical tone

Visual speech (lipreading) supports speech perception not only when the auditory signal is limited, degraded, or miss-ing, but also in mismatched auditory and visual speech component conditions when the auditory signal is clear and undegraded. While most of this research has been done with segments (consonants and vowels), research at MARCS has now provided evidence for visual speech cues for n...

Cantonese speakers were asked to identify spoken words as one of six Cantonese words differing only in tone. Words were presented in three modes: auditory-visual (AV), auditory only (AO), and visual only (VO).

Lexical Tone Perception in Early Infancy

In order to shed light on the perceptual reorganization of lexical tones in the first year of life, in the current study, we tested Dutch native infants (6, 9, 11-month-old) on their discrimination of Mandarin Chinese high rising tone (T2) and low-dipping tone (T3) using a visual fixation paradigm. The infants were habituated on multiple tokens produced by two female native speakers, carrying e...

Musical pitch and lexical tone perception with cochlear implants.

OBJECTIVE The purpose of the present study was to test the hypothesis that cochlear implant (CI) users' music perception is correlated with their lexical tone perception, and the two types of perception share similar mechanisms in electric hearing. DESIGN A lexical tone perception test and a pitch interval discrimination test were administered to a group of CI users and a group of normal-hear...
