A Brief Version of the Unhelpful Thoughts and Beliefs About Stuttering Scales: The UTBAS-6
Conclusions The brief UTBAS-6 provides a reliable and efficient means of screening the unhelpful thoughts and beliefs associated with speech-related anxiety among adults who stutter. Referral for a psychological assessment is recommended in cases where the UTBAS total score falls in or above the fifth decile. (Source: Journal of Speech, Language, and Hearing Research)

The Palin Parent Rating Scales: Parents' Perspectives of Childhood Stuttering and Its Impact
Conclusions The Palin Parent Rating Scale is a valid and reliable tool, providing a method of exploring parents' perceptions of stuttering, the impact it has on the child and themselves, and the parents' knowledge of and confidence in managing the stuttering. This is an important addition to the existing range of assessments that may be used to evaluate stuttering in children up to age 14;6 (years;months) and allows the wider targets of parent-led therapy programs to be evaluated.

Clinical Characteristics of Voice, Speech, and Swallowing Disorders in Oromandibular Dystonia
Conclusions The characteristics of dysarthria in oromandibular dystonia vary significantly from one patient to another due to differences in the set of affected muscles, so each patient should receive a personalized rehabilitation program. Dysarthria was the most prominent symptom, although spasmodic dysphonia was more frequent than expected. Further laboratory-based studies are needed to clarify the mechanisms and consequences of dysphagia in oromandibular dystonia. (Source: Journal of Speech, Language, and Hearing Research)

Dyslexia Limits the Ability to Categorize Talker Dialect
Conclusions The results imply that the phonological deficit in dyslexia arises from impaired access to intact phonological representations rather than from poorly specified representations. It can be presumed that the impeded access to implicit long-term memory representations for indexical (dialect) information is due to less efficient operations in working memory, including deficiencies in utilizing talker normalization processes.

Effects of Noise on Speech Recognition and Listening Effort in Children With Normal Hearing and Children With Mild Bilateral or Unilateral Hearing Loss
Conclusions Findings indicate poorer sentence recognition in children with NH and MBHL or UHL as SNR decreases. VRT results suggest that greater effort was expended when processing stimuli that were incorrectly identified. Increasing VRT with decreasing SNR for correct responses also supports greater effort in poorer acoustic conditions. The absence of significant hearing status differences suggests that VRT was not differentially affected by MBHL, UHL, or NH for children in this study.

Examining the Language Phenotype in Children With Typical Development, Specific Language Impairment, and Fragile X Syndrome
Conclusions Although boys with FXS have language deficits, they performed similarly to MLU-matched typically developing children on finiteness marking. This language profile differs from children with SLI, who present with a delay-within-a-delay profile with finiteness marking delays that exceed delays in MLU. Unscorable responses produced by the boys with FXS may reflect pragmatic deficits, which are prominent in this population. Assessment procedures should be carefully considered when examining language in boys with FXS. (Source: Journal of Speech, Language, and Hearing Research)

Conclusions The relationship between the SIN deficit and CP, and how they potentially affect reading in children with dyslexia, remains unclear. However, these results are inconsistent with the notion that children with dyslexia suffer from a low-level temporal processing deficit and rather suggest a role of nonsensory (e.g., attentional) factors in their speech perception difficulties.
