Concealing Stuttering at School: "When You Can't Fix It…the Only Alternative Is to Hide It".

Purpose: The purpose of this study was to explore experiences with concealing stuttering in children and young people who stutter based on recollections from adults. In addition, we explored how school-based speech therapists can be helpful or unhelpful to children who are concealing stuttering from the perspective of adults who stutter.

Method: Thirty adults who stutter, who previously or currently conceal stuttering, participated in semistructured interviews exploring their early experiences with hiding stuttering.

Stuttering Frequency, Speech Rate, Speech Naturalness, and Speech Effort During the Production of Voluntary Stuttering.

Purpose: Voluntary stuttering techniques involve persons who stutter purposefully interjecting disfluencies into their speech. Little research has been conducted on the impact of these techniques on the speech pattern of persons who stutter. The present study examined whether changes in the frequency of voluntary stuttering accompanied changes in stuttering frequency, articulation rate, speech naturalness, and speech effort.

Functional neural circuits that underlie developmental stuttering.

The aim of this study was to identify differences in functional and effective brain connectivity between persons who stutter (PWS) and typically developing (TD) fluent speakers, and to assess whether those differences can serve as biomarkers to distinguish PWS from TD controls. We acquired resting-state functional magnetic resonance imaging data in 44 PWS and 50 TD controls. We then used Independent Component Analysis (ICA) together with Hierarchical Partner Matching (HPM) to identify networks of robust, functionally connected brain regions that were highly reproducible across participants, and we assessed whether connectivity differed significantly across diagnostic groups.

Origin and Pawn scaling for adults who do and do not stutter: A preliminary comparison.

Purpose: In order to determine whether adults who stutter (AWS) would show changes in locus of causality during stuttering treatment and approximate those of adults who do not stutter (AWNS) this preliminary study compared the locus of causality as indicated by Origin and Pawn scaling procedures from two groups of young adults who do and do not stutter.

Method: A total of 20 age- and gender-matched undergraduate and graduate students who did (n = 10) and did not (n = 10) stutter participated. The AWS took part in a three week intensive stuttering treatment provided by the American Institute for Stuttering (AIS).

A functional imaging study of self-regulatory capacities in persons who stutter.

Developmental stuttering is a disorder of speech fluency with an unknown pathogenesis. The similarity of its phenotype and natural history with other childhood neuropsychiatric disorders of frontostriatal pathology suggests that stuttering may have a closely related pathogenesis. We investigated in this study the potential involvement of frontostriatal circuits in developmental stuttering.
