ABSTRACT
When the fundamental frequency ( Æ’0) is removed from a complex stimulus, the pitch of the Æ’0 is still perceived by the listener. Through the use of the scalp-recorded frequency-following response, this study examined the relative contributions of the Æ’0 and its harmonics in pitch processing by systematically manipulating the speech stimulus to remove component frequencies. 12 American and 12 Chinese adults were recruited. There were statistically significant effects of pitch strength and frequency error for the experimental-condition factor. There were significantly larger responses to the harmonics-only conditions than those obtained in the Æ’0-only and control conditions. No statistically significant difference was observed between the two groups of participants. These findings indicate that neural responses associated with individual harmonics dominate the pitch processing in the human brainstem, irrespective of whether the listener's native language is nontonal or tonal.

    To study the relation of pitch and duration processing in reading musical notation, a Stroop-like task was used by 20 non-musicians. A probe display was presented before each target note. Participants were required to process the tonal and metric information of the probe and then to make a match...

    Purpose: This study was conducted to determine whether the perceptions of nasal consonants in children with normal hearing and children with cochlear implants were predicted by the discontinuity hypothesis. Methods: Four groups participated: 8 adults, 8 children with normal hearing (ages 5-7...

    Purpose: Common wisdom suggests that listening in noise poses disproportionately greater difficulty for listeners with cochlear implants (CIs) than for peers with normal hearing (NH). The purpose of this study was to examine phonological, language, and cognitive skills that might help explain...

    The dynamic specification account of vowel recognition suggests that formant movement between vowel targets and consonant margins is used by listeners to recognize vowels. This study tested that account by measuring contributions to vowel recognition of dynamic (i.e., time-varying) spectral...

    Purpose: In individuals who stutter (IWS), speech fluency can be enhanced by altered auditory feedback, although it has adverse effects in control speakers. This indicates abnormalities in the auditory feedback loop in stuttering. Current motor control theories on stuttering propose an impaired...

    Purpose: The capacity of 6-month-old infants to discriminate a voicing contrast (/aba/-/apa/) on the basis of amplitude modulation (AM) cues and frequency modulation (FM) cues was evaluated. Method: Several vocoded speech conditions were designed to either degrade FM cues in 4 or 32 bands or...
