Lyssa Rome

Welcome to the Aphasia Access Aphasia Conversations Podcast. I'm Lyssa Rome. I'm a speech language pathologist on staff at the Aphasia Center of California, and I see clients with aphasia and other neurogenic communication disorders in my LPAA-focused private practice. I'm also a member of the Aphasia Access podcast Working Group. Aphasia Access strives to provide members with information, inspiration, and ideas that support their aphasia care through a variety of educational materials and resources.

I'm today's host for an episode that will feature Dr. Suma Devanga, who is selected as a 2024 Tavistock Trust for Aphasia Distinguished Scholar, USA and Canada. In this episode, we'll be discussing Dr. Devanga's research on collaborative referencing, gesture, and building rich communicative environments for people with aphasia.

Suma Devanga

Thank you, Lyssa, thank you for having me. And I would also like to thank Aphasia Access for this wonderful opportunity, and the Tavistock Trust for Aphasia and the Duchess of Bedford for recognizing my research through the Distinguished Scholar Award.

Lyssa Rome

So I wanted to start by asking you how you became interested in aphasia treatment.

Suma Devanga

I became interested in aphasia during my undergraduate and graduate programs, which was in speech language pathology in Mysore in India. I was really drawn to this population because of how severe the consequences were for these individuals and their families after the onset of aphasia. So I met hundreds of patients and families with aphasia who were really devastated by this sudden condition, and they were typically left with no job and little means to communicate with family and friends. So as a student clinician, I was very, very motivated to help these individuals in therapy, but when I started implementing the treatment methods that I had learned, what I discovered was that my patients were showing improvements on the tasks that we worked on in therapy. Their scores on clinical tasks also were improving, but none of that really mattered to them. What they really wanted was to be able to easily communicate with family, but they continued to struggle on that, and none of the cutting-edge treatment methods that I learned from this highly reputable program in India were impacting my patients' lives.

So I really felt lost, and that is when I knew that I wanted to do a PhD and study this topic more closely, and I was drawn to Dr. Julie Hengst's work, which looked at the bigger picture in aphasia. She used novel theoretical frameworks and used discourse analysis methods for tracking patient performance, as opposed to clinical tests. So I applied to the University of Illinois PhD program, and I'm so glad that she took me on as her doctoral student. And so that is how I ended up moving from India to the US and started my work in aphasia.

Lyssa Rome

I think that a lot of us can probably relate to what you're describing—that just that feeling of frustration when a patient might improve on some sort of clinical tasks, but still says this is not helping me in my life, and I know that for me, and I think for others, that is what has drawn us to the LPAA.

I wanted to sort of dive into your research by asking you a little bit more about rich communicative environments, and what you mean by that, and what you mean when you talk about or write about distributed communication frameworks.

Suma Devanga

So since I started my PhD, I have been interested in understanding how we can positively impact everyday communication for our patients with aphasia. As a doctoral student, I delved more deeply into the aphasia literature and realized that what I observed clinically with my patients in India was consistent with what was documented in the literature, and that was called the clinical-functional gap. And this really refers to the fact that we have many evidence-based aphasia treatments that do show improvements on clinical tasks or standardized tests, but there is very limited evidence on these treatments improving the functional use of language or the everyday communication, and this remains to be true even today.

So I think it becomes pretty important to understand what we are dealing with, like what is everyday communication? And I think many aphasia treatments have been studying everyday communication or conversational interactions by decontextualizing them or reducing them into component parts, like single words or phrases, and then we work our way up to sentence structures. Right? So this approach has been criticized by some researchers like Clark, who is an experimental psychologist, and he called such tasks as in vacuo, meaning that they are not really capturing the complexity of conversational interactions. So basically, even though we are clinicians, our ultimate goal is improving everyday communication, which is rich and emergent and complex, we somehow seem to be using tasks that are simplified and that removes all of these complexities and focuses more on simple or specific linguistic structures. So to understand the complexities of everyday communication, we have shifted to the distributed communication framework, which really originates from the cultural historical activity theories and theories from linguistic anthropology.

Dr. Julie Hengst actually proposed the distributed communication theory in her article in the Journal of Communication Disorders in 2015, which highlights that communication is not just an individual skill or a discrete concept, but it is rather distributed. And it is distributed in three ways: One is that it is distributed across various resources. We communicate using multiple resources, not just language. We sign, we use gestures, or facial expressions. We also interpret messages using such resources like dialects and eye gaze and posture, the social context, cultural backgrounds, the emotional states that we are in, and all of that matters. And we all know this, right? This is not new, and yet, we often give credit to language alone for communication, when in reality, we constantly...
