Dissociated Development of Speech and Limb Sensorimotor Learning in Stuttering: Speech Auditory-motor Learning is Impaired in Both Children and Adults Who Stutter
2020, NeuroscienceCitation Excerpt :The acuity of sensory processing itself during and after movement execution also warrants further investigation. Despite multiple reports of reduced oral somatosensory acuity in individuals who stutter (Archibald and De Nil, 1999; De Nil and Abbs, 1991; Howell et al., 1995; Loucks and De Nil, 2006a, 2006b; although see Daliri et al., 2013), auditory acuity for the detection of unpredictable, within-trial formant frequency perturbations was reported to not differ between stuttering and nonstuttering participants (Cai et al., 2012). However, the isolated vowel productions tested in the latter study were substantially longer (∼300 ms in duration) than those occurring in connected speech, and this additional time may have been beneficial for stuttering speakers to detect the formant changes.
Motor practice effects and sensorimotor integration in adults who stutter: Evidence from visuomotor tracking performance
2015, Journal of Fluency DisordersCitation Excerpt :In the present study visual feedback was always available to participants during both jaw and hand tracking tasks, which may have influenced performance of PWS and PWNS to a different degree. Prior work has shown that children (Howell, Sackin, & Rustin, 1995) and adults who stutter (Archibald & De Nil, 1999; Loucks & De Nil, 2006) performed as well as people who do not stutter in non-speech jaw movement task when visual feedback was available, and significantly less accurate in the absence of visual feedback. Researchers have theorized that the relative inaccuracy of jaw movements shown by children who stutter and adults who stutter in the absence of visual feedback may be explained by aberrant proprioceptive integration, suggesting an oral kinesthetic deficit (Archibald & De Nil, 1999; Loucks & De Nil, 2006; Loucks, De Nil, & Sasisekaran, 2007; cf. Namasivayam, van Lieshout, McIlroy, & De Nil, 2009).
