The current study assessed EF using nonverbal tasks of inhibition, shifting, and updating of working memory (WM) in school-age children with ASD. It also evaluated the association between children’s receptive and expressive language abilities and EF performance.Method: In this study, we sought to address variables that have contributed to inconsistencies...

Impact of background noise on recognition memory (Koeritzer et al., 2018)

Margaret A. Koeritzer, Chad S. Rogers, Kristin J. Van Engen & Jonathan E. Peelle
Purpose: The goal of this study was to determine how background noise, linguistic properties of spoken sentences, and listener abilities (hearing sensitivity and verbal working memory) affect cognitive demand during auditory sentence comprehension.Method: We tested 30 young adults and 30 older adults. Participants heard lists of sentences in quiet and in 8-talker babble at signal-to-noise ratios of +15 dB and +5 dB, which increased acoustic challenge but left the speech largely intelligible. Half of the...

Interprofessional collaborative practice in school (Pfeiffer et al., 2019)

Danika L. Pfeiffer, Stacey L. Pavelko, Debbie L. Hahs-Vaughn & Carol C. Dudding
Purpose: This study examined the models of collaboration used by school-based speech-language pathologists (SLPs) during the provision of special education services including factors predicting use of the interprofessional collaborative practice (IPP) model and barriers to collaboration.Method: School-based SLPs responded to a survey on models of collaboration within their work setting. Anchored vignettes were created to determine their engagement in 3 different models (i.e., multidisciplinary, interdisciplinary, and interprofessional) used in the provision of special education services...

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...

Multidimensional scaling plots of nonerror productions for all participants (Cler et al., 2017)

Gabriel J. Cler, Jackson C. Lee, Talia Mittelman, Cara E. Stepp & Jason W. Bohland

Distance between points is monotonically related to the L1-norm distance between high-dimensional kinematic feature vectors recorded and resampled for each syllable. Blue diamonds: /bi/, green circles: /bu/, orange stars: /da/, black triangles: /du/, purple arrows: /za/, red squares: /zi/. Lighter markers indicate trials produced under delay, while dark markers show trials...

Dual-task performance in Parkinson disease (Whitfield et al., 2019)

Jason A. Whitfield, Zoe Kriegel, Adam M. Fullenkamp & Daryush D. Mehta
Purpose: Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and without PD.Method: Individuals with PD and neurologically healthy controls performed speech tasks (reading and extemporaneous speech tasks) and an oscillatory manual task (a counterclockwise circle-drawing...

Influence of efferent inhibition on SPIN (Yashaswini & Maruthy, 2019)

L. Yashaswini & Sandeep Maruthy
Purpose: The study aimed to assess the relationship between the level-dependent function of efferent inhibition and speech perception in noise across different intensities of suppressor and across different signal-to-noise ratios (SNRs) of speech.Method: Twenty-six young normal-hearing adults participated in the study. Contralateral suppression of transient evoked otoacoustic emissions (TEOAEs) was measured for 3 levels of suppressor (40, 50, and 60 dB SPL). Speech identification score (SIS) was measured at 5 ipsilateral SNR conditions (quiet, 0,...

Age at implantation, learning, and cognition (Marschark et al., 2019)

Marc Marschark, Louise Duchesne & David Pisoni
Purpose: Age at cochlear implantation frequently is assumed to be a key predictor of pediatric implantation benefits, but outcomes related to learning and cognition appear inconsistent. This critical assessment examines relevant literature in an effort to evaluate the impact of age at implantation in those domains for individuals who received their devices as children.Method: We examined 44 peer-reviewed articles from 2003 to 2018 considering age at implantation and conducted statistical analyses regarding its impact on...

Word learning differences (Alt et al., 2019)

Mary Alt, Shelley Gray, Tiffany P. Hogan, Nora Schlesinger & Nelson Cowan
Purpose: The purpose of our study was to test the hypotheses (a) that children with dyslexia have spoken word learning deficits primarily related to phonology and (b) that children with dyslexia and concomitant developmental language disorder (DLD) have word learning deficits related to both phonology and semantic processing when compared to peers with typical development (TD).Method: Second-graders with dyslexia (n = 82), concomitant dyslexia and DLD (dyslexia + DLD; n = 40), and TD (n...

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...

MC production in aphasia and controls (Dalton & Richardson, 2019)

Sarah Grace Hudspeth Dalton & Jessica D. Richardson
Purpose: The purposes of this study are to provide clinicians and researchers with introductory psychometric data for the main concept analysis (MCA), a measure of discourse informativeness, and specifically, to provide descriptive and comparative statistical information about the performance of a large sample of persons not brain injured (PNBIs) and persons with aphasia (PWAs) on AphasiaBank discourse tasks.Method: Transcripts of 5 semi-spontaneous discourse tasks were retrieved from the AphasiaBank database and scored according to detailed...

Professionals’ opinions on barriers to and importance of interdisciplinary collaboration were also of interest.Method: A 59-item online survey was distributed to SLPs and SPs in the United States through state professional organizations and social media posts. A total of 320 respondents completed the survey and met criteria. Perceptions of...

Treatment intensity in acquired apraxia of speech (Wambaugh et al., 2018)

Julie L. Wambaugh, Sandra Wright, Emily Boss, Shannon C. Mauszycki, Catharine DeLong, William Hula & Patrick J. Doyle
Purpose: This investigation was designed to examine the effects of treatment intensity (i.e., dose frequency) on the outcomes of Sound Production Treatment (SPT) for acquired apraxia of speech.Method: Five men with chronic apraxia of speech and aphasia received both intense SPT (3 hr per day/3 days per week) and nonintense/traditional SPT (SPT-T; 1 hr per day/3 days per week) in the context of single-case experimental designs. Each treatment was applied separately to a designated set...

Speech fluency in apraxia of speech (Harmon et al., 2019)

Tyson G. Harmon, Adam Jacks & Katarina L. Haley
Purpose: Slowed speech and interruptions to the flow of connected speech are common in aphasia. These features are also observed during dual-task performance for neurotypical adults. The purposes of this study were to determine (a) whether indices of fluency related to cognitive–linguistic versus motor processing would differ between speakers with aphasia plus apraxia of speech (AOS) and speakers with aphasia only and (b) whether cognitive load reduces fluency in speakers with aphasia with and without...

Hearing impairment and disrupted sleep (Clarke et al., 2019)

Nathan A. Clarke, Derek J. Hoare & Edward C. Killan
Purpose: Hearing impairment (HI) is the most common sensory impairment and may negatively impact sleep through reduced auditory input. Factors associated with HI such as anxiety regarding communication in daily life may also adversely impact an individual’s sleep. Here, research on the relationship between HI and sleep disruption was catalogued using scoping review methodology.Method: A systematic strategy was employed to search various electronic databases. This review is reported according to the Preferred Reporting Items for...

Diagnostic accuracy of recall and past tense (Redmond et al., 2019)

Sean M. Redmond, Andrea C. Ash, Tyler T. Christopulos & Theresa Pfaff
Purpose: Measures of linguistic processing and grammatical proficiency represent strong candidates for adaptation into language screeners for early elementary students. One key barrier, however, has been the lack of consensus around the preferred reference standard for assigning affected status. Diagnostic accuracies associated with sentence recall and past tense marking index measures were examined relative to 5 different reference standards of language impairment: receipt of language services, clinically significant levels of parental concern, low performance on...

Judgment of emotion in speech: Three-factor bar graphs for emotion categories "fear," "disgust," "sadness," "happiness," and "neutral" (Morgan & Ferguson, 2017)

Shae D. Morgan & Sarah Hargus Ferguson
"Communication partners of individuals with hearing loss are often counseled and trained to 'speak clearly' to help their partners receive this intelligibility benefit and improve communication. However, audiology patients sometimes complain anecdotally of communication partners sounding angry when in fact these communication partners are only trying to speak clearly. In the present study, we investigated the basis for these complaints by examining whether listeners perceive anger or other emotional content when they listen to speech...

Subcortical representation of voice onset time (Tamura et al., 2019)

Shunsuke Tamura, Kazuhito Itoh, Nobuyuki Hirose & Shuji Mori
Purpose: The purpose of this study was to investigate whether speech perception would reflect small latency changes in subcortical speech representation.Method: Twelve native Japanese listeners participated in the experiment. Those listeners participated in speech identification task and auditory brainstem response (ABR) measurement using /d/–/t/ continuum stimuli varying in voice onset time (VOT) with manipulation of the amplitude of initial noise (consonant) portion, the duration of which corresponded to VOT.Results: Increasing the noise portion amplitude lengthened...

Predictors of main concept production (Rivera et al., 2017)

Ana Rivera, Jonathan Hirst & Lisa A. Edmonds
Purpose: A conceptual framework of bilingual aphasia assessment requires an understanding of the variables that influence discourse in bilingual speakers. This study aimed to determine predictors of main concept (MC) production, a measure of discourse completeness, as well as the effect of language dominance on MCs.Method: The Nicholas and Brookshire (1993) picture stimuli were used to elicit English and Spanish discourse in 83 young bilinguals. Participant-reported variables (e.g., proficiency self-ratings) and measured language variables (e.g.,...

Visual supports for children with ASD (McTee et al., 2019)

Haley M. McTee, Deborah Mood, Tammy Fredrickson, Amy Thrasher & Angela Yarnell Bonino
Purpose: One in 59 children is diagnosed with autism spectrum disorder (ASD). Due to overlapping symptoms between hearing loss and ASD, children who are suspected of having ASD require an audiological evaluation to determine their hearing status for the purpose of differential diagnosis. The purpose of this article is twofold: (a) to increase audiologists’ knowledge of ASD by discussing the challenges associated with testing and interpreting clinical data for children with ASD or suspected ASD...

Fundamental frequency and rate on synthetic speech (Vojtech et al., 2019)

Jennifer M. Vojtech, Jacob P. Noordzij, Gabriel J. Cler & Cara E. Stepp
Purpose: This study investigated how modulating fundamental frequency (f0) and speech rate differentially impact the naturalness, intelligibility, and communication efficiency of synthetic speech.Method: Sixteen sentences of varying prosodic content were developed via a speech synthesizer. The f0 contour and speech rate of these sentences were altered to produce 4 stimulus sets: (a) normal rate with a fixed f0 level, (b) slow rate with a fixed f0 level, (c) normal rate with prosodically natural f0 variation,...

RULE: Development of a reading comprehension measure (Kucheria et al., 2018)

Priya Kucheria, McKay Moore Sohlberg, HyeonJin Yoon, Stephen Fickas & Jason Prideaux
Purpose: There is a lack of quick, reliable, and valid standardized reading comprehension assessments appropriate for postsecondary readers. We attempted to address this gap by designing Read, Understand, Learn, & Excel (RULE), a reading comprehension measure that employs sentence verification and recall tasks to assess reading comprehension. This article describes the exploratory study undertaken to construct RULE and then examines the preliminary concurrent validity and alternate form reliability of this measure.Method: The RULE measure was...
