Inner speech and overt speech (Stark et al., 2017)

Brielle C. Stark, Sharon Geva & Elizabeth A. Warburton
Preserved inner speech alongside relatively poor overt speech has been documented in some persons with aphasia (PWA), but the relationship of overt speech with inner speech is still largely unclear, as few studies have directly investigated these factors. The present study investigates the relationship of preserved inner speech in aphasia with selected measures of language and cognition.
Supplemental Material S1. Participant biographic demographics.
Supplemental Material S2. Percentage correct from inner speech and overt speech examination for all...

Current engineering methods for acquiring, analyzing, and modeling speech data present the opportunity to integrate speech data into the scientific process. Additionally, machine...

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...

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...
