Abstract
PURPOSE Text-to-speech (TTS) technology potentially benefits people with aphasia by presenting content through two modalities simultaneously; however, for this to help, eye fixations must synchronize with the auditory rendition of words. Researchers have yet to explore how often and to what extent people with aphasia achieve modality synchronization. This retrospective analysis examined the percent of words people with aphasia see and hear concurrently when reading passages presented via TTS technology. Text-to-speech (TTS) technology potentially benefits people with aphasia by presenting content through two modalities simultaneously; however, for this to help, eye fixations must synchronize with the auditory rendition of words. Researchers have yet to explore how often and to what extent people with aphasia achieve modality synchronization. This retrospective analysis examined the percent of words people with aphasia see and hear concurrently when reading passages presented via TTS technology. METHOD Nine adults with aphasia had their eye movements tracked while processing TTS passages at a preselected default rate of 150 words per minute. Modality synchronization occurred whenever fixation on a written word occurred during the time span beginning 300 ms before auditory presentation and ending at the next word's initiation. Correlations between standardized test scores, unsupported reading rate, and modality synchronization percentages were informative about the association of aphasia and reading impairment severity with achievement of synchronicity. RESULTS Three participants demonstrated consistent modality synchronization; average synchronicity ranged from 67% to 76% of passage words. One participant displayed inconsistent synchronization within passages and achieved an average of 58%. The remaining five participants rarely achieved synchronization, with fixations typically lagging substantially behind the auditory presentation. A significant positive correlation occurred between paragraph reading comprehension test scores and modality synchronization percentages. CONCLUSIONS A default TTS presentation rate does not result in dual modality synchronization for most people with aphasia. This lack of synchronization may contribute to inconsistencies in the benefit people with aphasia experience when provided with TTS support.

Metacognitive accuracy predicts self-reported quality of life following traumatic brain injury. Brain Inj 2024; 38:361-367. [PMID: 38329033 DOI: 10.1080/02699052.2024.2311336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 01/24/2024] [Indexed: 02/09/2024]
Abstract
OBJECTIVE Metacognition and quality of life (QoL) are both adversely affected by traumatic brain injury (TBI), but the relation between them is not fully understood. As such, the purpose of this study was to determine the degree to which metacognitive accuracy predicts QoL in individuals with TBI. METHODS Eighteen participants with moderate-to-severe TBI completed a stimulus-response task requiring the discrimination of emotions depicted in pictures of faces and then provided a retrospective confidence judgment after each response. Metacognitive accuracy was calculated using participants' response accuracy and confidence judgment accuracy. Participants also completed the Quality of Life After Brain Injury (QOLIBRI) questionnaire to assess QoL in various areas of functioning. RESULTS Performance of a linear regression analysis revealed that higher metacognitive accuracy significantly predicted lower overall QoL. Additionally, higher metacognitive accuracy significantly predicted lower QoL related to cognition and physical limitations. CONCLUSION The study results provide evidence of an inverse relation between metacognitive performance and QoL following TBI. Metacognitive changes associated with TBI and their relation to QoL have several clinical implications for TBI rehabilitation.

Variations in Eye-Gaze Behaviors Evident When Five Adults With Aphasia-Based Alexia Read Multisentence Passages. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2024; 33:173-188. [PMID: 37870914 DOI: 10.1044/2023_ajslp-23-00160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 10/24/2023]
Abstract
PURPOSE The problems that people with aphasia encounter when reading passages are poorly understood. This study's purpose was in-depth examination of eye-gaze behaviors exhibited by five people with aphasia-based alexia. METHOD Five adults with aphasia-based alexia and five neurotypical adults (NAs) read paragraphs while having their eye movements recorded. Acquired data included descriptive characterization of overall eye-gaze behaviors and determination of the (a) percent of fixated words, (b) average fixation duration, (c) average initial and total summed fixation durations of processing attempts on individual words, and (d) effects of word length and frequency on fixation durations. Careful examination of these data allowed examination of consistencies and discrepancies among people with aphasia and supported speculation about underlying deficits. RESULTS Case participants exhibited unique fixation behaviors in comparison to one another and to neurotypical adults. Case participants' total reading time, percent of fixated words, average fixation duration, and average initial and total summed fixation durations on passage words exceeded those of neurotypical adults. Four of five exhibited positive word length and negative word frequency correlations with fixation durations. CONCLUSIONS People with aphasia display eye-gaze behaviors unique to them and differing from those of NAs when reading texts. Better understanding of the connection between specific eye-gaze behaviors and problems decoding words, linking them with lexical-semantic information, and constructing meaning from written content is necessary to further progress in developing effective assessment tools and treatments.

A Mixed-Methods Exploration of the Experience of People With Aphasia Using Text-to-Speech Technology to Support Virtual Book Club Participation. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2023; 32:2768-2791. [PMID: 37678193 PMCID: PMC10721254 DOI: 10.1044/2023_ajslp-23-00094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 05/25/2023] [Accepted: 07/14/2023] [Indexed: 09/09/2023]
Abstract
PURPOSE This mixed-methods research sought to examine the experience of people with aphasia who used text-to-speech (TTS) support to read a novel for virtual book club participation. METHOD Six people with chronic aphasia used a TTS system to review portions of a novel about which they conversed during eight virtual book club meetings occurring over 5 weeks. During one-on-one interactions prior to each meeting, participants answered comprehension questions and provided feedback about reading experiences. Then, during group meetings, they reviewed and discussed relevant book content and predicted upcoming content. During a structured individual interview, participants reflected on their supported reading and book club experience. RESULTS Participants reported a range of reading confidence prior to study participation, mostly influenced by decreased comprehension or reading speed. After book club participation, four participants expressed increased confidence. Some reported searching for key words and skipping difficult words as strategies additional to TTS support. All reviewed at least some book sections more than once either with or without TTS support. Highly motivated participants expressed low frustration and high reading ease and enjoyment. Perceived comprehension was roughly consistent with actual comprehension across participants. Most believed TTS support promoted faster reading than otherwise possible. Participants liked adjustable features affecting speech output rate, word or sentence highlighting, and font size. Psychosocial benefits included decreased isolation and increased friendship. CONCLUSIONS The findings extend previous evidence about perceived and actual benefits associated with TTS support. People with aphasia express positive experiences when given TTS support during book club participation.

Speech and Language Characteristics of Neurologically Healthy Adults When Describing the Modern Cookie Theft Picture: Mixing the New With the Old. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2023; 32:1110-1130.

Abstract
PURPOSE The Modern Cookie Theft picture has recently become available. This study's purpose was to compare (a) speech and language production by neurologically healthy adults (NHAs) given a generic instruction to describe the picture versus instruction to describe it as if talking with someone who was blind and (b) production during the first 90 s versus full samples. METHOD One hundred NHAs minus five outliers formed two participant groups. Each group heard either the original or modified task instruction. Transcriptions of resulting descriptions were analyzed regarding duration, word and T-unit productivity, content units (CUs), and main concepts (MCs) both in full and 90-s samples. Identified CUs and MCs were compared with existing lists from previous research. RESULTS Significantly longer samples and greater verbosity occurred with the modified versus original instruction even when limiting time to a 90 s maximum. With the modified instruction, CUs included 119 and 138 terms for truncated and full samples, respectively; participants mentioned 98 and 104 CUs, respectively, given the original instruction. MCs expressed were 18 and 19 for truncated and full samples, respectively, given the modified instruction; with the original instruction, this dropped to 11 and 12 MCs for truncated and full samples, respectively. Within samples, CU and MC repetitions were greater given modified rather than original instruction. CONCLUSIONS Normative productivity and content generation data are critical for guiding diagnostic efforts and treatment planning. Benefits and detriments associated with differing productivity and content redundancy secondary to varying instructions and analysis time frames are discussed.

Eye Fixation Behaviors and Processing Time of People With Aphasia and Neurotypical Adults When Reading Narratives With and Without Text-to-Speech Support. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2023; 66:276-295. [PMID: 36538505 DOI: 10.1044/2022_jslhr-22-00298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/17/2023]
Abstract
BACKGROUND Researchers have used eye-tracking technology to investigate eye movements in neurotypical adults (NAs) when reading. The technology can provide comparable information about people with aphasia (PWA). Eye fixations occurring when PWA do and do not have access to text-to-speech (TTS) technology are of interest because the support improves reading comprehension and decreases processing time for at least some PWA. AIMS This study's purpose was to examine forward, regressive, and off-track eye fixations when PWA and NAs read narratives in read-only (RO) and TTS conditions. A secondary aim was to examine the influence of eye fixations on processing time. METHOD AND PROCEDURE A Tobii Dynavox Pro Spectrum eye tracker recorded eye movements of nine PWA and nine NAs while reading narratives in two conditions. Movements of interest were forward fixations; within-word, within-sentence, and previous-sentence regressive fixations; and off-track fixations. OUTCOMES AND RESULTS PWA exhibited significantly more forward and regressive fixations in the RO than TTS condition, whereas NAs showed opposite behaviors. NAs had significantly more off-track fixations in the TTS than RO condition, whereas PWA exhibited no difference across conditions. PWA took significantly longer to process content in the RO condition, whereas NAs took longer in the TTS condition. CONCLUSIONS PWA and NAs differ in important ways when processing texts with and without TTS support. Examining eye-tracking data provides a means of gaining insight into the decoding and reading comprehension challenges of PWA and helps elucidate how assistive technology can mediate these challenges.

Comprehension, Processing Time, and Modality Preferences When People With Aphasia and Neurotypical Healthy Adults Read Books: A Pilot Study. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2022; 31:2569-2590.

Abstract
BACKGROUND Many people with aphasia (PWA) want to read books. Text-to-speech (TTS) technology sometimes provides comprehension and processing time benefits when PWA read short, multisentence passages. Currently, no research examines the effect of TTS support when PWA read books. AIMS This study's primary purpose was to examine comprehension accuracy and total processing time of PWA and neurotypical healthy adults (NHAs) when reading book sections in read-only versus TTS-supported conditions. A secondary aim was to examine condition preference and perceived degree of understanding by people in both participant groups. METHOD AND PROCEDURE Ten PWA and 10 NHAs alternated between read-only and TTS-supported conditions to read a book. Participants answered comprehension questions and provided feedback about their reading experience, condition preference, and desire to use TTS technology for future book reading. Outcomes and Result: Overall, PWA exhibited less accurate comprehension and slower processing times compared to NHAs in both conditions. No significant comprehension accuracy difference occurred between conditions for either group. However, four PWA exhibited a 10% or greater increase in comprehension accuracy when receiving TTS support. A significant processing time difference occurred with PWA processing text faster with TTS support, whereas NHAs did not demonstrate processing time differences. Most PWA preferred the TTS condition and expressed a desire to use TTS technology in the future. Most NHAs expressed the opposite preference. CONCLUSIONS TTS support during book reading promotes faster processing without compromising comprehension for PWA. Clinicians should discuss with PWA the relative importance of comprehension accuracy, processing time, and comfort with technology when determining whether using TTS support during book reading is desirable.

Abstract
Access to extensive, interdisciplinary rehabilitation following stroke is necessary to optimize recovery. Telerehabilitation is an appropriate model for delivering these services. However, given its relatively recent increase in popularity as a service delivery model, researchers have yet to explore the feasibility of interprofessional coordination and collaboration as a guiding framework for telerehabilitation and the effects of team-based remote service delivery on recovery of body functions and activities. This case example reports the development, implementation, and progression of a post-acute treatment program delivered via telerehabilitation to a woman with left hemorrhagic stroke. As is typical, therapy time alone afforded insufficient practice to exploit neuroplasticity and ensure maintenance and generalization of improved functioning; hence, the team worked collaboratively to encourage interdisciplinary activities outside scheduled treatment sessions. Standardized and informal assessments administered at the start and conclusion of treatment confirmed improved functioning as did the client's progress toward independent living and return to work. Implications for telerehabilitation practices are discussed.

Abstract
PURPOSE Writing challenges can cause ongoing distress and limit resumption of pre-injury activities following traumatic brain injury (TBI); however, little TBI research or clinical practice addresses written communication. Understanding the writing perceptions and experiences of adults engaged in intensive, inpatient rehabilitation following hospital discharge for TBI is an initial step in addressing this situation. METHOD Transcendental phenomenology served to structure this qualitative research. Six adults between 2 and 6 months post-TBI participated in a common experience of writing about a personal memorable event. Standardized test scores and symptom ratings provided descriptive information about participants. Additionally, participants completed the Neurobehavioral Symptom Inventory and NASA Task Load Index and engaged in semistructured interviews to describe writing perceptions and experiences. RESULTS Data analysis revealed themes and subthemes about writing perceptions, challenges, and support strategies. Participants varied in their perceptions of post-injury writing changes. Test results revealed areas of challenge for all participants, but only half reported awareness of writing changes. Those aware of changes differed from other participants regarding word retrieval, memory, and concentration as well as overall effort expended, frustration, and performance quality. Although all participants relied on writing supports, only one had adjusted multiple writing strategies following injury. CONCLUSIONS Some adults with TBI are aware of writing changes while receiving posthospital, inpatient rehabilitation services, but others deny such changes. This differs from reports concerning later recovery stages, perhaps because few functional writing opportunities arise during rehabilitation. Application of compensatory strategies specific to post-injury writing challenges is unlikely while awareness remains limited.

Reading Comprehension and Processing Time When People With Aphasia Use Text-to-Speech Technology With Personalized Supports and Features. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2022; 31:342-358. [PMID: 34941376 PMCID: PMC9135027 DOI: 10.1044/2021_ajslp-21-00182] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 09/12/2021] [Accepted: 09/22/2021] [Indexed: 05/19/2023]
Abstract
BACKGROUND Person-centered approaches promote consistent use of supportive technology and feelings of empowerment for people with disabilities. Feature personalization is an aspect of person-centered approaches that can affect the benefit people with aphasia (PWA) derive from using text-to-speech (TTS) technology as a reading support. AIMS This study's primary purpose was to compare the comprehension and processing time of PWA when performing TTS-supported reading with preferred settings for voice, speech output rate, highlighting type, and highlighting color versus unsupported reading. A secondary aim was to examine initial support and feature preference selections, preference changes following TTS exposure, and anticipated functional reading activities for utilizing TTS technology. METHOD AND PROCEDURE Twenty PWA read passages either via written text or text combined with TTS output using personally selected supports and features. Participants answered comprehension questions, reevaluated their preference selections, and provided feedback both about feature selections and possible future TTS technology uses. OUTCOMES AND RESULTS Comprehension accuracy did not vary significantly between reading conditions; however, processing time was significantly less in the TTS-supported condition, thus suggesting TTS support promoted greater reading speed without compromising comprehension. Most participants preferred the TTS condition and several anticipated benefits when reading lengthy and difficult materials. Alterations to initial settings were relatively rare. CONCLUSIONS Personalizing TTS systems is relevant to person-centered interventions. Reading with desired TTS system supports and features promotes improved reading efficiency by PWA compared with reading without TTS support. Attending to client preferences is important when customizing and implementing TTS technology as a reading support.

Abstract
PURPOSE Written expression challenges following traumatic brain injury (TBI) in adults have received little clinical attention but can substantially affect quality of life and the success of reintegration efforts. Assessment tools and procedures are lacking despite the likelihood of post-TBI problems with microstructure (e.g., productivity, spelling accuracy) and macrostructure (e.g., topic adherence, organization) aspects of written language. The lack of standardized procedures forces reliance on informal methods to determine writing strengths and challenges. METHOD A combination of assessment procedures allowed for evaluation of the productivity and efficiency, adherence to writing conventions (e.g., spelling, sentence structure, punctuation), and macrostructure organization (e.g., story grammar, topic adherence) of written narratives collected from five adults with TBI. RESULTS Use of multiple assessment methods revealed disparate writing challenges across the five case examples. The differing writing profiles underscore the necessity of evaluating multiple aspects of written narratives. CONCLUSIONS The described analysis methods can help clinicians determine areas of strength and challenge in written work generated by adults with TBI. Examination of multiple aspects of writing is key to garnering a comprehensive appraisal of post-TBI writing.

Abstract
People with spinal cord injury (SCI) require extensive rehabilitation to maximize independence and quality of life. Much of this treatment occurs on an outpatient basis through telerehabilitation or clinic-based services. Synchronous telerehabilitation has become increasingly common in recent years, but many professionals remain reluctant to suggest it when clinic-based services are available. This survey study explored case managers' perceptions regarding advantages and disadvantages of synchronous telerehabilitation versus clinic-based physical therapy services for people with SCI. Respondents were 89 case managers responsible for service provision coordination. Results showed a significant preference for clinic-based rather than telerehabilitation physical therapy services. Relative experience with the two service delivery models significantly affected perceptions. Only facilitating travel convenience differed significantly as a reason for recommending one service delivery method over the other. The incongruity between perceptions about synchronous telerehabilitation and existing literature about its cost, convenience, and efficacy suggests a need for additional education.

Abstract
People with aphasia often have reading impairments that affect participation in daily activities. Text-to-speech (TTS) devices are technology-based supports that can facilitate processing of written materials. The purpose of this study was to gather information about the reading behaviors and TTS technology perceptions of people with aphasia who had first learned about system features and options. Sixteen people with chronic aphasia participated in single, one-on-one instructional and guided practice sessions using TTS systems. They answered close-ended questions about current reading behaviors and materials and ways they believed these would change given TTS system access. Participants reported reading at home and community locations. Most read calendars, newspapers, magazines, and mail. Participants who did not read lengthy materials - such as newspapers, magazines, and novels - indicated their interest in these materials would likely increase given TTS support. Although participants did not predict substantial comprehension changes given TTS support, most expressed interest in the technology after learning about it. Thus, people with aphasia perceive TTS systems as helpful for comprehending lengthy materials. Given modest predictions about comprehension benefits, presenting TTS as one of several support strategies is an appropriate recommendation.

Abstract
INTRODUCTION Text-to-speech (TTS) technology is a possible reading support for people with aphasia; however, adoption for functional reading remains rare, and people with aphasia may have limited knowledge about TTS. Given this situation coupled with inherent communication challenges associated with aphasia, the purpose of this convergent mixed methods study was to explore the perceptions of participants about desired features, benefits, and drawbacks of TTS technology after having engaged in one-on-one education and guided practice activities. METHODS Nineteen adults with chronic aphasia completed a single education and guided practice session followed by close-ended questions and participation in a semi-structured interview to explain preferences, concerns, beliefs, and opinions about potential TTS technology benefits and drawbacks. Three participants had previously used TTS technology for functional reading; all others had some prior exposure but did not use a system for functional purposes. RESULTS Seventeen of 19 participants expressed TTS technology interest after education and guided practice activities. Participants endorsed selection of a preferred voice, control of speech output rate, and highlighting as priority features. Frequently endorsed benefits were improved comprehension and increased reading independence; some participants believed they would succeed in reading a greater variety of materials, communicate more with others, participate in more reading activities, and/or read faster. The greatest concern was mastering device operation; other concerns related to understanding the voice output, needing another person's help for system use, and matching the speech output rate to a preferred reading rate. CONCLUSIONS Overall, most participants had positive perceptions about possible benefits afforded by TTS technology. Practitioners need to provide opportunities for people with aphasia to learn about and explore TTS systems to determine whether adoption is desired.

Effect of Digital Highlighting on Reading Comprehension Given Text-to-Speech Technology for People with Aphasia. APHASIOLOGY 2020; 35:200-221. [PMID: 33731970 PMCID: PMC7959096 DOI: 10.1080/02687038.2020.1787728] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Accepted: 06/09/2020] [Indexed: 05/19/2023]
Abstract
BACKGROUND Many people with aphasia have a strong desire to participate in reading activities despite persistent reading challenges. Digital reading devices and text-to-speech (TTS) technology are increasing in popularity and have the potential to help people with aphasia. Systematic investigation of modifiable TTS features provides a means of exploring this potential. AIMS This study's aim was to evaluate the effect of digital highlighting synchronised with TTS auditory and written output on reading comprehension by people with aphasia and to determine their highlighting preferences. METHODS & PROCEDURES This work was registered with clinicaltrials.gov and assigned the clinical trial registry number 01446r prior to initiation of data collection. Twenty-five adults with aphasia read and listened to passages presented in three synchronised highlighting conditions: sentence highlighting, single word highlighting, and no highlighting. Participants answered comprehension questions, selected most and least preferred conditions, and provided feedback explaining highlighting preferences. OUTCOME & RESULTS Comprehension accuracy did not vary significantly across presentation conditions, but participants preferred either single word or sentence highlighting over no highlighting. CONCLUSIONS Neither word nor sentence highlighting benefitted or hindered comprehension by people with aphasia as a group, but individual differences may occur. Clinicians should attend to personal preferences when implementing digital highlighting as a reading support strategy.

Abstract
Purpose Accessing auditory and written material simultaneously benefits people with aphasia; however, the extent of benefit as well as people's preferences and experiences may vary given different auditory presentation rates. This study's purpose was to determine how 3 text-to-speech rates affect comprehension when adults with aphasia access newspaper articles through combined modalities. Secondary aims included exploring time spent reviewing written texts after speech output cessation, rate preference, preference consistency, and participant rationales for preferences. Method Twenty-five adults with aphasia read and listened to passages presented at slow (113 words per minute [wpm]), medium (154 wpm), and fast (200 wpm) rates. Participants answered comprehension questions, selected most and least preferred rates following the 1st and 3rd experimental sessions and after receiving performance feedback, and explained rate preferences and reading and listening strategies. Results Comprehension accuracy did not vary significantly across presentation rates, but reviewing time after cessation of auditory content did. Visual data inspection revealed that, in particular, participants with substantial extra reviewing time took longer given fast than medium or slow presentation. Regardless of exposure amount or receipt of performance feedback, participants most preferred the medium rate and least preferred the fast rate; rationales centered on reading and listening synchronization, benefits to comprehension, and perceived normality of speaking rate. Conclusion As a group, people with aphasia most preferred and were most efficient given a text-to-speech rate around 150 wpm when processing dual modality content; individual differences existed, however, and mandate attention to personal preferences and processing strengths.

Effects of Written, Auditory, and Combined Modalities on Comprehension by People With Aphasia. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2019; 28:1206-1221.

Abstract
Background People with aphasia experience reading challenges affecting participation in daily activities. Researchers have found combined auditory and written presentation modalities help people with aphasia comprehend contrived sentences and narratives, but less is known about the effects of combined modalities on functional, expository text comprehension. Aims This study's purpose was to examine comprehension accuracy, reviewing time, and modality preference of people with aphasia when presented with edited newspaper articles in written only, auditory only, and combined written and auditory modalities. Method and Procedure Twenty-eight adults with chronic aphasia read and/or listened to 36 passages. Following each passage, participants answered comprehension questions. Then, they ranked the modalities in accordance with preference and provided a rationale for their ranking. Outcomes and Results Comprehension accuracy was significantly better in the combined than auditory-only condition and in the written-only than auditory-only condition; the difference between combined and written-only conditions was not significant. Reviewing time differed significantly among conditions with the written-only condition taking longest and the auditory-only condition taking shortest. Most participants preferred the combined condition. Conclusions Access to combined modalities helps people with aphasia comprehend expository passages such as those found in newspapers better than auditory-only presentation. Furthermore, combined presentation decreases reviewing time from that needed for unsupported reading without compromising comprehension accuracy. Given that most participants preferred combined modality presentation, providing simultaneous auditory and written access to content through text-to-speech technology is a viable strategy when aphasia results in persistent reading challenges.

Abstract
Purpose This case study documents the effectiveness of a multicomponent intervention for an adolescent with acquired alexia and agraphia following severe traumatic brain injury. Method Initial testing revealed severe central alexia and surface agraphia with concomitant anomic aphasia. Intervention components included sight word drills, modified Multiple Oral Reading (MOR) procedures, functional reading tasks, and modified Copy and Recall Treatment. Intervention spanned 2 months with sessions 5 days per week. Data collection and analysis involved monitoring sight word decoding, reading speed and decoding errors during MOR, and spelling accuracy of Copy and Recall Treatment words. Follow-up testing occurred at intervention conclusion. Results Sight word mastery for 315 words progressed from 66.35% to 100% over 5 weeks and was maintained thereafter. MOR materials progressed from Grade 1 to Grade 5. Initial reading speed was 31 words per minute with errors on 15% of words. At program completion, reading speed was 47 words per minute with 7% decoding errors despite increased difficulty of reading material. The participant demonstrated initial mastery of 15 spelling lists containing 15 words each and sustained mastery (2 additional consecutive weeks of 100% accuracy) of 8 lists. Follow-up assessment revealed improvements consistent with 3-4 grade levels but persistent impairment relative to premorbid functioning. Conclusion The multicomponent program was effective in promoting substantial improvement, although surface alexia and agraphia persisted after 2 months of treatment. The case provides an example of the type and extent of progress possible given minimal initial recovery but systematic intervention within the context of intensive postacute rehabilitation.

Abstract
Purpose Every adult with aphasia displays a unique constellation of language comprehension skills and varies in the benefit derived from different content presentation formats. For many, multiple modality presentation enhances comprehension. This study's purpose was to determine the comprehension benefits for people with mild, moderate, and severe aphasia when hearing, reading, or simultaneously hearing and reading single sentences. Method Twenty-seven adults with aphasia performed a repeated-measures experiment across 3 conditions. Participants read and/or listened to sentence stimuli and selected from 4 images the 1 matching the sentence. Participants also indicated condition preference. Results Participants demonstrated significantly greatest accuracy during simultaneous written and auditory stimulus presentation. Performance patterns varied within aphasia severity groups. Individuals with mild and moderate aphasia demonstrated minimal performance differences across conditions, and people with severe aphasia were significantly more accurate in the combined modality than the written-only modality. Overall, participants required the longest response time in the written-only condition; however, participants were most efficient with auditory content. Condition preferences did not always mirror accuracy; however, the majority reported a preference for combined content presentation. Conclusions Results suggest some people with aphasia may benefit from combined auditory and written modalities to enhance comprehension efforts.

Abstract
PURPOSE Language and cognitive disruptions following traumatic brain injury (TBI) can negatively affect written expression and may result in increased difficulty achieving academic, vocational, social, and personal goals; however, scarce literature exists about TBI's effect on writing abilities. The purpose of this qualitative study was to describe the experiences and perceptions of people with TBI regarding their engagement in writing activities. METHOD A transcendental phenomenological design structured the research. Data collection from 11 adults with TBI included gathering demographic and background information, completion of a TBI Symptom Checklist, and engagement in semistructured interviews. RESULTS Four major themes and 21 subthemes about postinjury writing recovery and current writing status emerged from the data analysis. Participants reported the extent to which writing difficulties interfered with daily activities and identified support strategies used to address persistent challenges. CONCLUSION Understanding the writing experiences and perceptions of people with TBI can guide professionals in designing assessments and interventions to facilitate educational, vocational, social, and personal success following injury.

Abstract
Background Incidents potentially causing mild brain injury (BI) are common, and most people recover rapidly; however, a subset experiences long-lasting challenges.
Objective This study used latent class analysis to identify a subset of college students presenting chronic symptomatology consistent with a mild BI diagnosis and pseudo-class mean equality tests to examine relations between latent classes and BI event and academic outcome variables.
Methods Participants were 118/423 undergraduates self-reporting possible mild BIs through a survey about general health, daily habits, academic performance, and potential BI events. Twenty-four cognitive, physiological, or socio-emotional sequelae served to identify symptomatology profiles.
Results A three-class model including 11% with high symptomatology, 49% with moderate symptomatology, and 40% with negligible symptomatology provided excellent fit and entropy. Symptoms best separating high and moderate classes were memory, thinking speed, new learning, and attention problems. Mean equality tests revealed no significant difference in number of BI events across classes, but high symptomatology respondents were significantly less likely to lose consciousness and significantly more likely to have lower grade point averages and to have failed courses than moderate symptomatology respondents.
Discussion Cognitive problems are paramount in distinguishing college students with chronic high symptomatology following BI from those with moderate and negligible symptomatology. Because high symptomatology class individuals differ academically from their counterparts, a functional consequence of mild BI appears to exist.
Conclusion About 1 in 10 undergraduate students self-reporting BI events experiences chronic symptomatology affecting general health and academic achievement. Because they may benefit from supportive services, accurate identification is critical.

The effect of human engagement depicted in contextual photographs on the visual attention patterns of adults with traumatic brain injury. JOURNAL OF COMMUNICATION DISORDERS 2017; 69:58-71. [PMID: 28783543 DOI: 10.1016/j.jcomdis.2017.07.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/22/2016] [Revised: 07/03/2017] [Accepted: 07/17/2017] [Indexed: 06/07/2023]
Abstract
UNLABELLED Photographs are a frequently employed tool for the rehabilitation of adults with traumatic brain injury (TBI). Speech-language pathologists (SLPs) working with these individuals must select photos that are easily identifiable and meaningful to their clients. In this investigation, we examined the visual attention response to camera- (i.e., depicted human figure looking toward camera) and task-engaged (i.e., depicted human figure looking at and touching an object) contextual photographs for a group of adults with TBI and a group of adults without neurological conditions. Eye-tracking technology served to accurately and objectively measure visual fixations. Although differences were hypothesized given the cognitive deficits associated with TBI, study results revealed little difference in the visual fixation patterns of adults with and without TBI. Specifically, both groups of participants tended to fixate rapidly on the depicted human figure and fixate more on objects in which a human figure was task-engaged than when a human figure was camera-engaged. These results indicate that strategic placement of human figures in a contextual photograph may modify the way in which individuals with TBI visually attend to and interpret photographs. In addition, task-engagement appears to have a guiding effect on visual attention that may be of benefit to SLPs hoping to select more effective contextual photographs for their clients with TBI. Finally, the limited differences in visual attention patterns between individuals with TBI and their age and gender matched peers without neurological impairments indicates that these two groups find similar photograph regions to be worthy of visual fixation. LEARNING OUTCOMES Readers will gain knowledge regarding the photograph selection process for individuals with TBI. In addition, readers will be able to identify camera- and task-engaged photographs and to explain why task-engagement may be a beneficial component of contextual photographs.

Comprehension of synthetic speech and digitized natural speech by adults with aphasia. JOURNAL OF COMMUNICATION DISORDERS 2017; 69:15-26.

Abstract
Using text-to-speech technology to provide simultaneous written and auditory content presentation may help compensate for chronic reading challenges if people with aphasia can understand synthetic speech output; however, inherent auditory comprehension challenges experienced by people with aphasia may make understanding synthetic speech difficult. This study's purpose was to compare the preferences and auditory comprehension accuracy of people with aphasia when listening to sentences generated with digitized natural speech, Alex synthetic speech (i.e., Macintosh platform), or David synthetic speech (i.e., Windows platform). The methodology required each of 20 participants with aphasia to select one of four images corresponding in meaning to each of 60 sentences comprising three stimulus sets. Results revealed significantly better accuracy given digitized natural speech than either synthetic speech option; however, individual participant performance analyses revealed three patterns: (a) comparable accuracy regardless of speech condition for 30% of participants, (b) comparable accuracy between digitized natural speech and one, but not both, synthetic speech option for 45% of participants, and (c) greater accuracy with digitized natural speech than with either synthetic speech option for remaining participants. Ranking and Likert-scale rating data revealed a preference for digitized natural speech and David synthetic speech over Alex synthetic speech. Results suggest many individuals with aphasia can comprehend synthetic speech options available on popular operating systems. Further examination of synthetic speech use to support reading comprehension through text-to-speech technology is thus warranted.

Abstract
PURPOSE Individuals with acquired brain injury (ABI) often struggle due to inadequate planning and execution skills for completing nonroutine tasks. This study's purpose was to pilot ecologically valid procedures to assess planning for and execution of prospective daily activities. METHOD Participants included 9 adults with histories of severe ABI and 9 controls. Data collection included both prospective task planning and execution. First, participants created a plan for later execution of daily tasks in accordance with preestablished rules. Over the subsequent 10 days, participants independently attempted task completion. Differences within and between participant groups regarding planning and task performance were evaluated statistically and through examiner observation. RESULTS Participants with ABI implemented minimal planning strategies. They demonstrated highly variable performance and displayed substantially greater difficulty initiating and successfully executing tasks in adherence to rules than participants without ABI. CONCLUSIONS Evaluating planning strategies and execution of novel prospective tasks is a crucial but often neglected aspect of assessment following ABI. Implementing ecologically valid procedures to evaluate this aspect of functioning can reveal individual strengths and challenges and provide guidance for developing effective intervention programs. Examining potential roles played by planning and strategy execution provides critical assessment information relating to independent living.

Abstract
PURPOSE The purpose of this investigation was to measure the effect of message type (i.e., action, naming) on the visual attention patterns of individuals with and without traumatic brain injury (TBI) when viewing grids composed of 3 types of images (i.e., icons, decontextualized photographs, and contextualized photographs). METHOD Fourteen adults with TBI and 14 without TBI-assigned either to an action or naming message condition-viewed grids composed of 3 different image types. Participants' task was to select/sustain visual fixation on the image they felt best represented a stated message (i.e., action or naming). RESULTS With final fixation location serving as a proxy for selection, participants in the naming message condition selected decontextualized photographs significantly more often than the other 2 image types. Participants in the action message condition selected contextualized photographs significantly more frequently than the other 2 image types. Minimal differences were noted between participant groups. CONCLUSIONS This investigation provides preliminary evidence of the relationship between image and message type. Clinicians involved in the selection of images used for message representation should consider the message being represented when designing supports for people with TBI. Further research is necessary to fully understand the relationship between images and message type.

Abstract
This study investigated the effectiveness of using an observational checklist to facilitate early teacher referral of children suspected of having language problems. Twelve classroom teachers completed the Observational Checklist of Conversational Skills on 37 kindergarten and first grade students whom they suspected had language problems (i.e., were at-risk for language impairments) and 37 age-matched peers. Students in the at-risk group were evaluated using the Clinical Evaluation of Language Fundamentals-Revised (CELF-R) and the Communication Abilities Diagnostic Test (CADeT). Scores revealed that 25 of the 37 subjects (67.57%) were at least 1.5 standard deviations below the mean and 14 of the 37 (37.84%) were at least 2.0 standard deviations below the mean on one or both of the measures. Follow-up data collected one year later on 36 of the 37 at-risk students revealed that 27 (75%) had been referred for special education evaluation. Fourteen of those referred were verified as language impaired and/or learning disabled and one subject was verified as other health impaired (ADHD); six subjects did not qualify for services and, for the remaining six, the evaluation process was not yet complete. Of the 37 age-matched peers, two (5.41 %) had been referred for evaluation; one did not qualify for services and the other was verified as articulation impaired. Implications for using checklists to facilitate early teacher referral are discussed.

Abstract
OBJECTIVE Concomitant visual and cognitive impairments following traumatic brain injuries (TBIs) may be problematic when the visual modality serves as a primary source for receiving information. Further difficulties comprehending visual information may occur when interpretation requires processing inferential rather than explicit content. The purpose of this study was to compare the accuracy with which people with and without severe TBI interpreted information in contextually rich drawings. PARTICIPANTS Fifteen adults with and 15 adults without severe TBI. DESIGN Repeated-measures between-groups design. MAIN MEASURES Participants were asked to match images to sentences that either conveyed explicit (ie, main action or background) or inferential (ie, physical or mental inference) information. The researchers compared accuracy between participant groups and among stimulus conditions. RESULTS Participants with TBI demonstrated significantly poorer accuracy than participants without TBI extracting information from images. In addition, participants with TBI demonstrated significantly higher response accuracy when interpreting explicit rather than inferential information; however, no significant difference emerged between sentences referencing main action versus background information or sentences providing physical versus mental inference information for this participant group. CONCLUSIONS Difficulties gaining information from visual environmental cues may arise for people with TBI given their difficulties interpreting inferential content presented through the visual modality.

Abstract
PURPOSE The purpose of the study was to compare the visual attention patterns of adults with aphasia and adults without neurological conditions when viewing visual scenes with 2 types of engagement. METHOD Eye-tracking technology was used to measure the visual attention patterns of 10 adults with aphasia and 10 adults without neurological conditions. Participants viewed camera-engaged (i.e., human figure facing camera) and task-engaged (i.e., human figure looking at and touching an object) visual scenes. RESULTS Participants with aphasia responded to engagement cues by focusing on objects of interest more for task-engaged scenes than camera-engaged scenes; however, the difference in their responses to these scenes were not as pronounced as those observed in adults without neurological conditions. In addition, people with aphasia spent more time looking at background areas of interest and less time looking at person areas of interest for camera-engaged scenes than did control participants. CONCLUSIONS Results indicate people with aphasia visually attend to scenes differently than adults without neurological conditions. As a consequence, augmentative and alternative communication (AAC) facilitators may have different visual attention behaviors than the people with aphasia for whom they are constructing or selecting visual scenes. Further examination of the visual attention of people with aphasia may help optimize visual scene selection.

Abstract
OBJECTIVE The researchers explored the return-to-work experiences of five adults with severe traumatic brain injuries (TBIs) and those associated with them by performing a qualitative, multiple case study investigation involving in-depth, semi-structured interviews. Selection of this qualitative methodology allowed for personal, individualized accounts of adults with TBI returning to work. Specifically, this methodology promoted accurate representation of the idiosyncratic nature of each participant's experiences. METHODS The researchers asked individuals to participate based on the diversity of their vocational experiences following TBI. RESULTS Four of the five participants had returned to their pre-injury jobs. Two were subsequently fired and, at the time of research participation, were unemployed. One participant never returned to paid employment; however, he had held two volunteer positions for several years post-injury. Salient content from interview transcripts allowed for the identification of five to eight themes pertinent to each case. CONCLUSIONS Interpretation of the themes led to three main conjectures about return-to-work experiences following TBI: (a) job satisfaction may relate more to involvement in productive activities than monetary compensation; (b) adults with TBI can be successful in holding and maintaining positions with high cognitive demands; and

Abstract
The purpose of this preliminary investigation was to explore the role photographs play in communication interactions involving neurotypical adults. Participants included 10 people from 2 age groups: younger adults between 23 and 25 years of age and older adults between 61 and 74 years of age. Referencing photographs to support one-on-one conversations between an examiner and either a younger or older neurotypical adult speaker occurred approximately 20% of the time. Younger participants relied solely on nonverbal communication in the form of a pointing gesture to convey their intent less than 2% of the time, whereas older participants never relied solely on pointing gestures to convey intent. This suggests that typical speakers treat the referencing of photographs as a supplemental rather than primary communication strategy during face-to-face interactions.

Abstract
PRIMARY OBJECTIVE Computer-based treatments for attention problems have become increasingly popular and available. The researchers sought to determine whether improved performance by survivors of severe traumatic brain injury (TBI) on two computer-based treatments generalized to improvements on comparable, untrained tasks and ecologically-plausible attention tasks comprising a standardized assessment. RESEARCH DESIGN The researchers used an -A-B-A-C-A treatment design repeated across four adult survivors of severe TBI. METHODS AND PROCEDURES Participants engaged in 8 weeks of intervention using both Attention Process Training-3 (APT-3) and Lumosity™ (2010) Brain Games. Two participants received APT-3 treatment first, while the other two received Lumosity™ treatment first. All participants received both treatments throughout the course of two, 1-month intervention phases. MAIN OUTCOMES AND RESULTS Individual growth curve analyses showed participants made significant improvements in progressing through both interventions. However, limited generalization occurred: one participant demonstrated significantly improved performance on one of five probe measures and one other participant showed improved performance on some sub-tests of the Test of Everyday Attention; no other significant generalization results emerged. These findings call into question the assumption that intervention using either APT-3 or Lumosity™ will prompt generalization beyond the actual tasks performed during treatment.

Abstract
Adults with acquired language impairments secondary to stroke, traumatic brain injury, and neurodegenerative diseases are candidates for communication supports outside of the traditional restoration-based approaches to intervention. Recent research proves repeatedly that augmentative and alternative communication (AAC) provides a means for participation, engagement, conversation, and message transfer when individuals can no longer expect full return of pre-morbid communication skills and that inclusion of communication supports should begin early. We discuss current research and future directions for integrated systems of technical supports that include low-technology, high tech, and partner-dependent strategies for adults with severe and chronic aphasia, cognitive-communication problems resulting from traumatic brain injuries, and primary progressive aphasia.

Abstract
PURPOSE To determine the effect of personal relevance and contextualization of images on the preferences and word-picture matching accuracy of people with severe aphasia. METHOD Eight adults with aphasia performed 2 experimental tasks to reveal their preferences and accuracy during word-picture matching. The researchers used 3 types of visual stimuli-personally relevant, contextualized photographs; non-personally relevant, contextualized photographs; and noncontextualized, iconic images-paired with 3 types of target words-labels of people or objects, actions, and socially relevant events-as the stimulus materials. RESULTS Data analysis showed that participants (a) preferred using personally relevant, contextualized photographs rather than other types of photographs/images to represent target words and (b) performed more accurate word-picture matching when presented with target words associated with personally relevant, contextualized photographs than target words associated with noncontextualized or nonpersonalized photographs/images. CONCLUSIONS Clinically, the findings highlight the importance of using personally relevant, contextualized photographs rather than generic contextualized photographs or noncontextualized, iconic images to support the communication attempts of people with aphasia who cannot communicate effectively using natural speech alone.
