Using visual scene displays to create a shared communication space for a person with aphasia

Background: Low-tech visual scene displays (VSDs) combine contextually rich pictures and written text to support the communication of people with aphasia. VSDs create a shared communication space in which a person with aphasia and a communication partner co-construct messages. Aims: The researchers examined the effect of low-tech VSDs on the content and quality of communicative interactions between a person with aphasia and unfamiliar communication partners. Methods & Procedures: One person with aphasia and nine unfamiliar communication partners engaged in short, one-on-one conversations about a specified topic in one of three conditions: shared-VSDs, non-shared-VSDs, and no-VSDs. Data included discourse analysis scores reflecting the conceptual complexity of utterances, content unit analyses of information communication partners gathered from the interaction, and Likert-scale responses from the person with aphasia about his perception of communicative ease and effectiveness. Outcomes & Results: Comparisons made across conditions revealed: (a) the most conversational turns occurred in the shared-VSDs condition; (b) communication partners produced utterances with higher conceptual complexity in the shared-VSDs condition; (c) the person with aphasia conveyed the greatest number of content units in the shared-VSDs condition; and (d) the person with aphasia perceived that information transfer, ease of conversational interaction, and partner understanding were best in the shared-VSDs condition. Conclusions: These findings suggest that low-tech VSDs have an impact on the manner and extent to which a person with aphasia and a communication partner contribute to conversational interactions involving information transfer.

Using Visual Scene Displays as Communication Support Options for People with Chronic, Severe Aphasia: A Summary of AAC Research and Future Research Directions

Abstract Research about the effectiveness of communicative supports and advances in photographic technology has prompted changes in the way speech-language pathologists design and implement interventions for people with aphasia. The purpose of this paper is to describe the use of photographic images as a basis for developing communication supports for people with chronic aphasia secondary to sudden-onset events due to cerebrovascular accidents (strokes). Topics include the evolution of AAC-based supports as they relate to people with aphasia, the development and key features of visual scene displays (VSDs), and future directions concerning the incorporation of photographs into communication supports for people with chronic and severe aphasia.

The impact of interface design during an initial high-technology AAC experience: a collective case study of people with aphasia.

Abstract The purpose of this collective case study was to describe the communication behaviors of five people with chronic aphasia when they retold personal narratives to an unfamiliar communication partner using four variants of a visual scene display (VSD) interface. The results revealed that spoken language comprised roughly 70% of expressive modality units; variable patterns of use for other modalities emerged. Although inconsistent across participants, several people with aphasia experienced no trouble sources during the retells using VSDs with personally relevant photographs and text boxes. Overall, participants perceived the personally relevant photographs and the text as helpful during the retells. These patterns may serve as a springboard for future experimental investigations regarding how interface design influences the communicative and linguistic performance of people with aphasia.

Assessment With Children Who Need Augmentative and Alternative Communication (AAC): Clinical Decisions of AAC Specialists

Purpose The purpose of this study was to explore how speech-language pathologists (SLPs) who are augmentative and alternative communication (AAC) specialists approach the assessment process for 2 case studies, 1 child with cerebral palsy and 1 with autism spectrum disorder. The aim of the study was to answer the following questions: (a) How do clinicians with expertise approach the AAC assessment process for children with developmental disabilities? (b) Can any initial hypothesis be drawn about how SLPs approach the assessment of children with motor versus social interactive deficits? Method This study used a phenomenological qualitative design. The researchers conducted 2 in-depth, semistructured interviews with 8 SLPs who specialized in AAC and self-identified as primarily working with children. Results Four major themes emerged from the data: area of assessment, method of assessment, evaluation preparation, and parent education. Each major theme contained multiple subthemes and categories within those subthemes. Conclusions Participants discussed similar areas of assessment for both cases, indicating that some aspects of AAC assessment are universal. However, the specific aspects of what they were assessing and how they went about assessing them differed between the 2 cases. The results of the current study provide an outline of an assessment protocol for children with complex communication needs.
