Consonant age-of-acquisition effects in nonword repetition (Moore et al., 2017)

Michelle W. Moore, Julie A. Fiez & Connie A. Tompkins
Purpose: Most research examining long-term-memory effects on nonword repetition (NWR) has focused on lexical-level variables. Phoneme-level variables have received little attention, although there are reasons to expect significant sublexical effects in NWR. To further understand the underlying processes of NWR, this study examined effects of sublexical long-term phonological knowledge by testing whether performance differs when the stimuli comprise consonants acquired later versus earlier in speech development.Method: Thirty (Experiment 1) and 20 (Experiment 2) college students...

Language outcomes in children who are deaf and hard of hearing (Daub et al., 2017)

Olivia Daub, Marlene P. Bagatto, Andrew M. Johnson & Janis Oram Cardy
Purpose: Early auditory experiences are fundamental in infant language acquisition. Research consistently demonstrates the benefits of early intervention (i.e., hearing aids) to language outcomes in children who are deaf and hard of hearing. The nature of these benefits and their relation with prefitting development are, however, not well understood.Method: This study examined Ontario Infant Hearing Program birth cohorts to explore predictors of performance on the Preschool Language Scale–Fourth Edition at the time of (N =...

Investigating a nonspeech differentiation task (Small et al., 2018)

Hailey C. Small, Tara McAllister & Maria I. Grigos
Purpose: Clinically, a task of alternating tongue lateralization has been used to evaluate the ability to independently control the tongue and jaw, with jaw movement interpreted as a sign of poor tongue–jaw differentiation. However, there is a lack of normative data regarding jaw movement during this task and whether this changes over the course of development. This study quantified relative tongue and jaw movement during alternating tongue lateralization for typical speakers across age ranges and...

& Janna B. Oetting
Purpose: We compared teacher ratings as measured by the Teacher Rating of Oral Language and Literacy (TROLL; Dickinson, McCabe, & Sprague, 2001, 2003) and Children’s Communication Checklist–Second Edition (CCC-2; Bishop, 2006) to 2 established screeners, the Part II of the Diagnostic Evaluation of Language Variation–Screening Test (DELV-ST-II; Seymour, Roeper, & de Villiers, 2003) and Dynamic Indicators of Basic Early Literacy Skills–Next (DIBELS; Good, Gruba, & Kaminski, 2009), and then examined whether teacher ratings alone or...

New Sentence Recognition Materials Using a Basic Non-Native English Lexicon (Calandruccio et al., 2012)

Lauren Calandruccio & Rajka Smiljanic
Purpose The objective of this project was to develop new sentence test materials drawing on a basic non-native English lexicon that could be used to test speech recognition for various listener populations. These materials have been designed to provide a test tool that is less linguistically biased, compared with materials that are currently available, for sentence recognition for non-native as well as native speakers of English.
Method One hundred non-native speakers of English were interviewed...

Computer-Administered Nonword Repetition Task (Polišenská & Kapalková, 2014)

Kamila Polišenská & Svetlana Kapalková
Purpose A range of nonword repetition (NWR) tasks are used in research and clinical applications, but compliance rates among young children remain low. Live presentation is usually used to improve compliance rates, but this lacks the consistency of recorded stimuli. In this study, the authors examined whether a novel delivery of NWR stimuli based on recorded material could provide improved compliance rates in young children, thereby reducing research bias.
Method The novel NWR task with...

Monolingual-Mode English, Monolingual-Mode French, and Bilingual-Mode Stimuli Used (Wilson & Gick, 2014)

Ian Wilson & Bryan Gick
Purpose Previous work has shown that monolingual French and English speakers use distinct articulatory settings, the underlying articulatory posture of a language. In the present article, the authors report on an experiment in which they investigated articulatory settings in bilingual speakers. The authors first tested the hypothesis that in order to sound native-like, bilinguals must use distinct, language-specific articulatory settings in monolingual mode. The authors then tested the hypothesis that in bilingual mode, a bilingual...

Angela M. AuBuchon, David B. Pisoni & William G. Kronenberger
Purpose The purpose of this study was to report how verbal rehearsal speed (VRS), a form of covert speech used to maintain verbal information in working memory, and another verbal processing speed measure, perceptual encoding speed, are related to 3 domains of executive function (EF) at risk in cochlear implant (CI) users: verbal working memory, fluency-speed, and inhibition-concentration.
Method EF, speech perception, and language outcome measures were obtained from 55 prelingually deaf, long-term CI users...

Evidence for a General Auditory Processing Deficit in Developmental Dyslexia (Christmann et al.)

Corinna A. Christmann, Thomas Lachmann & Claudia Steinbrink
Purpose It is unknown whether phonological deficits are the primary cause of developmental dyslexia or whether they represent a secondary symptom resulting from impairments in processing basic acoustic parameters of speech. This might be due, in part, to methodological difficulties. Our aim was to overcome two of these difficulties: the comparability of stimulus material and task in speech versus nonspeech conditions.
Method In this study, the authors (a) assessed auditory processing of German vowel center...

Retroflex Versus Bunched in Treatment for Rhotic Misarticulation (Byun et al., 2014)

Tara McAllister Byun, Elaine R. Hitchcock & Michelle T. Swartz
Purpose To document the efficacy of ultrasound biofeedback treatment for misarticulation of the North American English rhotic in children. Because of limited progress in the first cohort, a series of two closely related studies was conducted in place of a single study. The studies differed primarily in the nature of tongue-shape targets (e.g., retroflex, bunched) cued during treatment. Method Eight participants received 8 weeks of individual ultrasound biofeedback treatment targeting rhotics. In Study 1, all...
