“…Notably, this is a prominent feature of stuttering behavior (Bloodstein and Ratner, 2008). It is important to recognize that the concept of an impaired utilization of auditory feedback for speech motor control by PSs is not novel (Yates, 1963) and the resolution of this dysfunction has been proposed as the mechanism underlying “fluency-inducing procedures” in PS (chorus reading, etc.) (Stager et al, 2003).…”

A study of the reproducibility and etiology of diffusion anisotropy differences in developmental stuttering: A potential role for impaired myelination

et al. 2010

Several diffusion tensor imaging (DTI) studies have reported fractional anisotropy (FA) reductions within the left perisylvian white matter (WM) of persistent developmental stutterers (PSs). However, these studies have not reached the same conclusions in regard to the presence, spatial distribution (focal/ diffuse), and directionality (elevated/reduced) of FA differences outside of the left perisylvian region. In addition, supplemental DTI measures (axial and radial diffusivities, diffusion trace) have yet to be utilized to examine the potential etiology of these FA reductions. Therefore, the present study sought to reexamine earlier findings through a sex- and age-controlled replication analysis and then to extend these findings with the aforementioned non-FA measures. The replication analysis showed that robust FA reductions in PSs were largely focal, left hemispheric, and within late-myelinating associative and commissural fibers (division III of the left superior longitudinal fasciculus, callosal body, forceps minor of the corpus callosum). Additional DTI measures revealed that these FA reductions were attributable to an increase in diffusion perpendicular to the affected fiber tracts (elevated radial diffusivity). These findings suggest a hypothesis that will be testable in future studies: that myelogenesis may be abnormal in PSs within left-hemispheric fiber tracts that begin a prolonged course of myelination in the first postnatal year.

“…In the speech literature, Goldiamond, Atkinson, and Bilger (1962) suggested that behavior in DAF might result from an attempt to cause maximal overlap between feedback and action, and Fairbanks and Guttman (1958) observed that DAF repetitions may serve to restore "normal phase relationships" (p. 20). Yates (1963b) noted that abnormal feedback such as DAF leads to an attempt to "restore the usual relationship" (p. 114) of synchronized feedback and action, and Howell et al (1983, p. 776) suggested that one strategy for overcoming DAF effects in tapping or Morse code tasks may be to synchronize the motor acts with the sound being produced. In the more specific proposal of Harrington (1988), the impaired speech behavior under DAF occurs because spoken syllable nuclei are produced to correspond with the expected (delayed) syllable nuclei.…”

Delayed auditory feedback and rhythmic tapping: Evidence for a critical interval shift

Delayed auditory feedback (DAF) impairs performance in speech, music, and tapping, with maximal impairment in speech occurring at a delay of about 200 msec. This critical interval has played a central role in many explanations of the DAF effect, including both closed-loop feedback explanations and alternative proposals. We investigated the nature of the critical interval in rhythmic tapping-in particular, whether the critical interval has a constant value or is dependent on performance rate. Three experiments in which a synchronization-continuation paradigm was used consistently showed that the critical interval shifted with different tapping rates, with maximal impairment occurring when the delay approximately equaled the tapping rate. We address the implications of these results for theories of DAF.

“…A difference in the nature of own speech audition between controls and people who stutter (PWS) has been proposed to underlie persistent developmental stuttering (PDS) since at least the introduction of feedback control speech-motor models in the 1950s (see review in Yates, 1963;Bloodstein, 1995). Two proposals for brainstem activity are germane.…”

Speech-motor and psycholinguistic models employ feedback control from an auditory stream corresponding to own voice. Such models underspecify how own voice is identified. It is proposed that coincidence detection between cochlear and vestibular streams identifies own voice in mammals (H1) and that the coincidence detection differs in people who stutter (H2). Vestibular-evoked myogenic potential (VEMP), an indirect measure of vestibular function, was assessed in 15 people who stutter, with controls paired on age and sex. VEMP amplitude was 8.5 dB smaller in people who stutter than paired controls (p = 0.035, 95% CI [-0.9, -16.1], t = -2.1, d = -0.8, conditional R2 = 0.88), suggesting an approximate halving in how they perceptually experience the vestibular component of own voice. H1 and H2 are supported in this initial test of both hypotheses. Discussion covers own voice identification, persistent developmental stuttering, speech-induced suppression, auditory scene analysis, and theories of mental content.
