The purpose of this article is to describe the iterative development of the DictionarySquared research platform, a web-based vocabulary program that provides individualized vocabulary instruction, and to report the results of 2 pilot studies examining the feasibility of implementation and potential effectiveness with high school students.Method: We describe our theory of change and...

Variables that influence binomial completion (Eaton & Newman, 2018)

Catherine Torrington Eaton & Rochelle S. Newman
Purpose: The goal of this research was to institute an evidence base behind commonly used elicitation materials known as binomials (e.g., “day and night”) that are commonly used for persons with aphasia (PWAs). The study explored a number of linguistic variables that could influence successful binomial completion in nonaphasic adults and PWAs.Method: Thirty nonaphasic adults and 11 PWAs were asked to verbally complete 128 binomials; responses were scored by accuracy and reaction time. Binomials were...

Multiple channels in sign-supported speech (Mastrantuono et al., 2019)

Eliana Mastrantuono, Michele Burigo, Isabel R. Rodríguez-Ortiz & David Saldaña
Purpose: The use of sign-supported speech (SSS) in the education of deaf students has been recently discussed in relation to its usefulness with deaf children using cochlear implants. To clarify the benefits of SSS for comprehension, 2 eye-tracking experiments aimed to detect the extent to which signs are actively processed in this mode of communication.Method: Participants were 36 deaf adolescents, including cochlear implant users and native deaf signers. Experiment 1 attempted to shift observers’ foveal...

Materials and metrics for Swedish speech tests (Witte & Köbler, 2019)

Erik Witte & Susanne Köbler
Purpose: As factors influencing human word perception are important in the construction of speech perception tests used within the speech and hearing sciences, the purposes of this study were as follows: first, to develop algorithms that can be used to calculate different types of word metrics that influence the speed and accuracy of word perception and, second, to create a database in which those word metrics were calculated for a large set of Swedish words.Method:...

RCT of speechreading training in deaf children (Pimperton et al., 2019)

Hannah Pimperton, Fiona Kyle, Charles Hulme, Margaret Harris, Indie Beedie, Amelia Ralph-Lewis, Elizabeth Worster, Rachel Rees, Chris Donlan & Mairéad MacSweeney
Purpose: We developed and evaluated in a randomized controlled trial a computerized speechreading training program to determine (a) whether it is possible to train speechreading in deaf children and (b) whether speechreading training results in improvements in phonological and reading skills. Previous studies indicate a relationship between speechreading and reading skill and further suggest this relationship may be mediated by improved phonological representations. This is important since many deaf children find learning to read to...

Application of the CCS in peer and adult contexts (Thiemann-Bourque et al., 2019)

Kathy S. Thiemann-Bourque, Nancy Brady & Lesa Hoffman
Purpose: The purpose of this study was to measure changes in communication of preschoolers with autism using the Communication Complexity Scale (CCS; Brady et al., 2012) and to examine the utility of the CCS in measuring pretreatment and posttreatment changes within peer and adult assessment contexts.Method: The CCS was used to code preassessment and postassessment for 23 children with autism randomly assigned to a treatment that incorporated a peer-mediated approach and a speech-generating device and...

Silent gap CAEPs in tinnitus and control subjects (Morse & Vander Werff, 2019)

Kenneth Morse & Kathy Vander Werff
Purpose: Previous research suggests the existence of gap detection impairments because of tinnitus. The current study aimed to determine whether there was objective evidence of gap impairment in individuals with tinnitus by recording silent gap in white noise cortical auditory evoked potentials (CAEPs) in a chronic tinnitus group and a no-tinnitus group. The results were compared to previous gap-evoked potential and behavioral gap detection studies.Method: Chronic tinnitus and no-tinnitus groups were formed by matching pairs...

Morphosyntactic production and WM in aphasia (Fyndanis et al., 2018)

Valantis Fyndanis, Giorgio Arcara, Paraskevi Christidou & David Caplan
Purpose: The present work investigated whether verbal working memory (WM) affects morphosyntactic production in configurations that do not involve or favor similarity-based interference and whether WM interacts with verb-related morphosyntactic categories and/or cue–target distance (locality). It also explored whether the findings related to the questions above lend support to a recent account of agrammatic morphosyntactic production: Interpretable Features’ Impairment Hypothesis (Fyndanis, Varlokosta, & Tsapkini, 2012).Method: A sentence completion task testing production of subject–verb agreement, tense/time...

Effects of aided AAC input (O'Neill et al., 2018)

Tara O’Neill, Janice Light & Lauramarie Pope
Purpose: The purpose of this meta-analysis was to investigate the effects of augmentative and alternative communication (AAC) interventions that included aided AAC input (e.g., aided AAC modeling, aided language modeling, aided language stimulation, augmented input) on communicative outcomes (both comprehension and expression) for individuals with developmental disabilities who use AAC.Method: A systematic search resulted in the identification of 26 single-case experimental designs (88 participants) and 2 group experimental designs (103 participants). Studies were coded in...

Misarticulations and word identification (Krueger et al., 2018)

Breanna I. Krueger, Holly L. Storkel & Utako Minai
Purpose: The purpose of the present studies was to determine how children’s identification and processing of misarticulated words was influenced by substitution commonness.Method: Sixty-one typically developing preschoolers across 3 experiments heard accurate productions of words (e.g., “leaf”), words containing common substitutions (e.g., “weaf”), and words containing uncommon substitutions (e.g., “yeaf”). On each trial, preschoolers chose between a real object picture (e.g., a leaf ) and a nonobject (e.g., an anomalous line drawing). Accuracy and processing...

Vocabulary instruction for emergent bilinguals (Crosson et al., 2019)

Amy C. Crosson, Margaret G. McKeown, Kelly P. Robbins & Kathleen J. Brown
Purpose: In this clinical focus article, the authors argue for robust vocabulary instruction with emergent bilingual learners both in inclusive classroom settings and in clinical settings for emergent bilinguals with language and literacy disorders. Robust vocabulary instruction focuses on high-utility academic words that carry abstract meanings and appear in texts across content areas (e.g., diminish, ambiguous). For emergent bilinguals, vocabulary instruction should be infused with morphological analysis emphasizing Latin roots to support students to problem-solve...

Involvement of communication partners (Biggs et al., 2019)

Elizabeth E. Biggs, Erik W. Carter & Carly B. Gilson
Purpose: The purpose of this study was to inform practice and research by identifying and synthesizing research on interventions in which natural communication partners implemented aided augmentative and alternative communication (AAC) modeling strategies.Method: A scoping review yielded 29 studies. Data were charted related to participant characteristics, intervention characteristics, partner instruction and assessment, and partner perspectives of social validity.Results: More than 157 peer and 100 adult communication partners (e.g., parents, special educators, paraprofessionals) implemented aided AAC...

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...

Typical items and their production frequencies in English and in Spanish

Prarthana Shivabasappa, Elizabeth D. Peña & Lisa M. Bedore
Spanish–English bilingual child and adult participants in the study were asked to generate as many words as they could for the given categories, first in one language and then in the other. First, the data obtained from 20 adult participants were analyzed to obtain the typical items. The production frequency of each item was calculated as the number of participants out of 20 who had generated that item for the respective category. Next, the five...

Processing of wh-questions by children with CIs (Schouwenaars et al., 2019)

Atty Schouwenaars, Mareike Finke, Petra Hendriks & Esther Ruigendijk
Purpose: The purpose of this study was to investigate the processing of morphosyntactic cues (case and verb agreement) by children with cochlear implants (CIs) in German which-questions, where interpretation depends on these morphosyntactic cues. The aim was to examine whether children with CIs who perceive the different cues also make use of them in speech comprehension and processing in the same way as children with normal hearing (NH).Method: Thirty-three children with CIs (age 7;01–12;04 years;...

Jennifer P. Lundine, Stacy M. Harnish, Rebecca J. McCauley, Deena Schwen Blackett, Alexandra Zezinka, Wei Chen & Robert A. Fox
Purpose: Summarizing expository passages is a critical academic skill that is understudied in language research. The purpose of this study was to compare the quality of verbal summaries produced by adolescents for 3 different discourse types and to determine whether a composite measure of cognitive skill or a test of expressive syntax predicted their performance.Method: Fifty adolescents listened to, and then verbally summarized, 1 narrative and 2 expository lectures (compare–contrast and cause–effect). They also participated...

Target and masker effects on infants’ and adults’ detection of speech (Oster & Werner, 2017)

Monika-Maria Oster & Lynne A. Werner
Purpose: Several investigators have compared infants’ detection of speech in speech and nonspeech maskers to evaluate developmental differences in masking. Such comparisons have produced contradictory results, possibly because each investigation used different stimuli. The current study examined target and masker effects on infants’ and adults’ detection of speech.Method: An observer-based procedure was used to compare infants’ and adults’ detection of the vowel /ʌ/ and the word “baby” in a 2-talker speech masker and matched speech-spectrum...

Mandarin EL SR based on WaveNet-CTC (Qian et al., 2019)

Zhaopeng Qian, Li Wang, Shaochuan Zhang, Chan Liu & Haijun Niu
Purpose: The application of Chinese Mandarin electrolaryngeal (EL) speech for laryngectomees has been limited by its drawbacks such as single fundamental frequency, mechanical sound, and large radiation noise. To improve the intelligibility of Chinese Mandarin EL speech, a new perspective using the automatic speech recognition (ASR) system was proposed, which can convert EL speech into healthy speech, if combined with text-to-speech.Method: An ASR system was designed to recognize EL speech based on a deep learning...

Luis M. T. Jesus, Joana Martinez, Joaquim Santos, Andreia Hall & Victoria Joffe
Purpose: This article reports on the effectiveness of a novel tablet-based approach to phonological intervention and compares it to a traditional tabletop approach, targeting children with phonologically based speech sound disorders (SSD).Method: Twenty-two Portuguese children with phonologically based SSD were randomly assigned to 1 of 2 interventions, tabletop or tablet (11 children in each group), and received intervention based on the same activities, with the only difference being the delivery. All children were treated by...

Cognitive processing and comprehension in developmental language disorder (Montgomery et al., 2018)

James W. Montgomery, Julia L. Evans, Jamison D. Fargo, Sarah Schwartz & Ronald B. Gillam
Purpose: We assessed the potential direct and indirect (mediated) influences of 4 cognitive mechanisms we believe are theoretically relevant to canonical and noncanonical sentence comprehension of school-age children with and without developmental language disorder (DLD). Method: One hundred seventeen children with DLD and 117 propensity-matched typically developing (TD) children participated. Comprehension was indexed by children identifying the agent in implausible sentences. Children completed cognitive tasks indexing the latent predictors of fluid reasoning (FLD-R), controlled attention...
