Expanding the scope: multimodal dimensions in aphasia discourse analysis-preliminary findings

Area of Science:

• Neurolinguistics
• Speech-Language Pathology
• Cognitive Science

Background:

• Aphasia, a language disorder post-brain injury, impairs communication and life participation.
• Traditional assessments may not fully capture the complex communication challenges faced by individuals with aphasia.
• Exploring multimodal communication in discourse analysis offers a more comprehensive assessment of narrative proficiency.

Purpose of the Study:

• To investigate the impact of incorporating multimodal communication elements into discourse analysis on the narrative outcomes of individuals with aphasia.
• To compare narrative proficiency scores using multimodal versus verbal-only assessment approaches.
• To examine the relationship between aphasia characteristics and the use of multimodal communication during storytelling.

Main Methods:

• Participants included individuals with chronic aphasia and healthy controls who completed a storytelling task.
• Macrolinguistic scores were collected using both verbal-only and multimodal scoring methods.
• Statistical analyses involved within-group, between-group, and correlational analyses to assess narrative performance and multimodal communication use.

Main Results:

• Individuals with aphasia demonstrated significantly higher macrolinguistic abilities when assessed using multimodal scoring compared to verbal-only scoring.
• Both fluent and nonfluent aphasia subtypes showed improved scores with multimodal assessment, particularly in Main Concepts.
• Meaning-laden gestures were the most prevalent nonverbal modality used, highlighting their importance in communication for individuals with aphasia.

Conclusions:

• Multimodal communication is crucial for accurately assessing discourse performance in individuals with aphasia.
• Assessment strategies should incorporate multimodal elements to gain deeper insights into linguistic abilities.
• Tailoring assessments to aphasia subtypes can inform targeted interventions and improve communication outcomes.
