A Survey of Clinician Decision Making When Identifying Swallowing Impairments and Determining Treatment.

J Speech Lang Hear Res 2018 Nov;61(11):2735-2756

Rehabilitation Sciences, College of Public Health and Health Professions, University of Florida, Gainesville.

Purpose: Speech-language pathologists (SLPs) are the primary providers of dysphagia management; however, this role has been criticized with assertions that SLPs are inadequately trained in swallowing physiology (Campbell-Taylor, 2008). To date, diagnostic acuity and treatment planning for swallowing impairments by practicing SLPs have not been examined. We conducted a survey to examine how clinician demographics and swallowing complexity influence decision making for swallowing impairments in videofluoroscopic images. Read More

Lexical Development in Young Children With Autism Spectrum Disorder (ASD): How ASD May Affect Intake From the Input.

J Speech Lang Hear Res 2018 Nov;61(11):2659-2672

Communication Sciences & Disorders, Emerson College, Boston, MA.

Purpose: Most children with autism spectrum disorder (ASD) have below-age lexical knowledge and lexical representation. Our goal is to examine ways in which difficulties with social communication and language processing that are often associated with ASD may constrain these children's abilities to learn new words and to explore whether minimizing the social communication and processing demands of the learning situation can lead to successful learning.

Method: In this narrative review of recent work on lexical development in ASD, we describe key findings on children's acquisition of nouns, pronouns, and verbs and outline our research program currently in progress aimed at further elucidating these issues. Read More

Executive Function in Deaf Children: Auditory Access and Language Access.

J Speech Lang Hear Res 2018 Aug;61(8):1970-1988

Department of Linguistics, University of Connecticut, Storrs.

Purpose: Deaf children are frequently reported to be at risk for difficulties in executive function (EF); however, the literature is divided over whether these difficulties are the result of deafness itself or of delays/deficits in language that often co-occur with deafness. The purpose of this study is to discriminate these hypotheses by assessing EF in populations where the 2 accounts make contrasting predictions.

Method: We use a between-groups design involving 116 children, ages 5-12 years, across 3 groups: (a) participants with normal hearing (n = 45), (b) deaf native signers who had access to American Sign Language from birth (n = 45), and (c) oral cochlear implant users who did not have full access to language prior to cochlear implantation (n = 26).

Evaluation of an Explicit Intervention to Teach Novel Grammatical Forms to Children With Developmental Language Disorder.

J Speech Lang Hear Res 2018 Aug;61(8):2062-2075

Department of Speech-Language-Hearing Sciences, University of Minnesota, Twin Cities.

Purpose: Unlike traditional implicit approaches used to improve grammatical forms used by children with developmental language disorder, explicit instruction aims to make the learner consciously aware of the underlying language pattern. In this study, we compared the efficacy of an explicit approach to an implicit approach when teaching 3 novel grammatical forms varying in linguistic complexity.

Method: The study included twenty-five 5- to 8-year-old children with developmental language disorder, 13 of whom were randomized to receive an implicit-only (I-O) intervention whereas the remaining 12 participants were randomized to receive a combined explicit-implicit (E-I) intervention to learn 3 novel grammatical forms.

Infant-Mother Acoustic-Prosodic Alignment and Developmental Risk.

J Speech Lang Hear Res 2018 Jun;61(6):1369-1380

Human Development and Family Studies, Purdue University, West Lafayette, IN.

Purpose: One promising early marker for autism and other communicative and language disorders is early infant speech production. Here we used daylong recordings of high- and low-risk infant-mother dyads to examine whether acoustic-prosodic alignment as well as two automated measures of infant vocalization are related to developmental risk status indexed via familial risk and developmental progress at 36 months of age.

Method: Automated analyses of the acoustics of daylong real-world interactions were used to examine whether pitch characteristics of one vocalization by the mother or the child predicted those of the vocalization response by the other speaker and whether other features of infants' speech in daylong recordings were associated with developmental risk status or outcomes.

Grammar Clinical Marker Yields Substantial Heritability for Language Impairments in 16-Year-Old Twins.

J Speech Lang Hear Res 2018 Jan;61(1):66-78

Department of Psychology, University of York, United Kingdom.

Purpose: There is a need for well-defined language phenotypes suitable for adolescents in twin studies and other large-scale research projects. Rice, Hoffman, and Wexler (2009) have developed a grammatical judgment measure as a clinical marker of language impairment, which has an extended developmental range to adolescence.

Method: We conducted the first twin analysis, along with associated phenotypic analyses of validity, of an abridged, 20-item version of this grammatical judgment measure (GJ-20), based on telephone administration using prerecorded stimuli to 405 pairs of 16-year-olds (148 monozygotic and 257 dizygotic) drawn from the Twins Early Development Study (Haworth, Davis, & Plomin, 2012).

Word Processing in Children With Autism Spectrum Disorders: Evidence From Event-Related Potentials.

J Speech Lang Hear Res 2017 12;60(12):3441-3455

Vanderbilt Kennedy Center for Research on Human Development and Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN.

Purpose: This investigation was conducted to determine whether young children with autism spectrum disorders exhibited a canonical neural response to word stimuli and whether putative event-related potential (ERP) measures of word processing were correlated with a concurrent measure of receptive language. Additional exploratory analyses were used to examine whether the magnitude of the association between ERP measures of word processing and receptive language varied as a function of the number of word stimuli the participants reportedly understood.

Method: Auditory ERPs were recorded in response to spoken words and nonwords presented with equal probability in 34 children aged 2-5 years with a diagnosis of autism spectrum disorder who were in the early stages of language acquisition. Read More

Accentuate the Negative: Grammatical Errors During Narrative Production as a Clinical Marker of Central Nervous System Abnormality in School-Aged Children With Fetal Alcohol Spectrum Disorders.

Authors:
John C Thorne

J Speech Lang Hear Res 2017 12;60(12):3523-3537

Department of Speech and Hearing Sciences, University of Washington, Seattle.

Purpose: The purpose of this study was to examine (a) whether increased grammatical error rates during a standardized narrative task are a more clinically useful marker of central nervous system abnormality in Fetal Alcohol Spectrum Disorders (FASD) than common measures of productivity or grammatical complexity and (b) whether combining the rate of grammatical errors with the rate of cohesive referencing errors can improve utility of a standardized narrative assessment task for FASD diagnosis.

Method: The method used was retrospective analysis of narrative and clinical data from 138 children (aged 7-12 years; 69 with FASD, 69 typically developing). Narrative analysis was conducted blind to diagnosis. Read More

Infant-Directed Speech Enhances Attention to Speech in Deaf Infants With Cochlear Implants.

J Speech Lang Hear Res 2017 11;60(11):3321-3333

Department of Otolaryngology-Head & Neck Surgery, The Ohio State University, Columbus.

Purpose: Both theoretical models of infant language acquisition and empirical studies posit important roles for attention to speech in early language development. However, deaf infants with cochlear implants (CIs) show reduced attention to speech as compared with their peers with normal hearing (NH; Horn, Davis, Pisoni, & Miyamoto, 2005; Houston, Pisoni, Kirk, Ying, & Miyamoto, 2003), which may affect their acquisition of spoken language. The main purpose of this study was to determine (a) whether infant-directed speech (IDS) enhances attention to speech in infants with CIs, as compared with adult-directed speech (ADS), and (b) whether the degree to which infants with CIs pay attention to IDS is associated with later language outcomes.

Neural Indices of Semantic Processing in Early Childhood Distinguish Eventual Stuttering Persistence and Recovery.

J Speech Lang Hear Res 2017 11;60(11):3118-3134

Department of Speech, Language, and Hearing Sciences, Purdue University, West Lafayette, IN.

Purpose: Maturation of neural processes for language may lag in some children who stutter (CWS), and event-related potentials (ERPs) distinguish CWS who have recovered from those who have persisted. The current study explores whether ERPs indexing semantic processing may distinguish children who will eventually persist in stuttering (CWS-ePersisted) from those who will recover from stuttering (CWS-eRecovered).

Method: Fifty-six 5-year-old children with normal receptive language listened to naturally spoken sentences in a story context. Read More

Predicting Intelligibility Gains in Dysarthria Through Automated Speech Feature Analysis.

J Speech Lang Hear Res 2017 11;60(11):3058-3068

Department of Speech and Hearing Science, Arizona State University, Tempe.

Purpose: Behavioral speech modifications have variable effects on the intelligibility of speakers with dysarthria. In the companion article, a significant relationship was found between measures of speakers' baseline speech and their intelligibility gains following cues to speak louder and reduce rate (Fletcher, McAuliffe, Lansford, Sinex, & Liss, 2017). This study reexamines these features and assesses whether automated acoustic assessments can also be used to predict intelligibility gains. Read More

Enhancing Auditory Selective Attention Using a Visually Guided Hearing Aid.

Authors:
Gerald Kidd

J Speech Lang Hear Res 2017 10;60(10):3027-3038

Department of Speech, Language, and Hearing Sciences and Hearing Research Center, Boston University, MA.

Purpose: Listeners with hearing loss, as well as many listeners with clinically normal hearing, often experience great difficulty segregating talkers in a multiple-talker sound field and selectively attending to the desired "target" talker while ignoring the speech from unwanted "masker" talkers and other sources of sound. This listening situation forms the classic "cocktail party problem" described by Cherry (1953) that has received a great deal of study over the past few decades. In this article, a new approach to improving sound source segregation and enhancing auditory selective attention is described. Read More
