Devaraju Behavioral and Neural Correlates of Auditory n-Back Task in Adults With and Without Stuttering ASHA 2019 All India Institute of Speech and Hearing, Manasagangothri, Mysuru, India 471-482 Volume 28 Issue 2s Purpose: Adults with stuttering (AWS) exhibit compromised phonological working memory abilities, poor central auditory processing, and impaired auditory processing especially during overt speech production tasks. However, these tasks are sensitive to language disturbances already found in them. Thus, in this study, monosyllables were used ruling out the language effects, and auditory working memory ability was evaluated in AWS using the n-back task. In specific, the auditory sensory input of the working memory mechanism was evaluated. Method:Thirty-two participants, 16 each of AWS and adults with no stuttering (AWNS), performed behavioral auditory 1-back and 2-back tasks. The long latency responses were also recorded during no-back and 2-back conditions from 64 electrode sites.Results:Results revealed no significant differences between the groups in any of the behavioral parameters such as reaction time, accuracy, false alarm rate, or d′. N1 amplitude modulation was noted in AWNS, which was absent in AWS. The segmentation analysis showed a left hemisphere–oriented topographical distribution in the N2 region in AWS irrespective of conditions, whereas the scalp topography was right hemisphere–oriented with the involvement of parietal channels in AWNS. The timing differences existed between AWS and AWNS in the intervals that a topographical distribution lasted in all throughout the time window of analysis.Conclusion:The results suggest altered neural pathway and hemispheric differences during auditory working memory tasks in AWS.
