How Everyday Speech Reflects Thinking Skills Across Adulthood
What is it about?
This study looked at whether everyday spoken language can reveal how well our thinking skills are working. These thinking skills, known as executive functions, help us plan, stay organized, and shift between ideas. We collected simple picture-description speech samples from adults aged 18 to 90 and analyzed features such as pauses, hesitations, and how smoothly the description flowed. We found that people who showed stronger executive function tended to produce speech with fewer disfluencies (for example, fewer “ums” or moments of searching for words). This relationship was present not only in older adults but across the entire adult lifespan.
Why is it important?
Speech is natural, quick to collect, and can be measured remotely, which makes it promising for large-scale or repeated monitoring of cognitive health. Most prior work focuses only on aging or dementia. Our study shows that everyday speech also reflects meaningful variations in thinking skills throughout adulthood. This opens the possibility of using speech-based tools to support earlier detection, everyday monitoring, and more accessible assessment alongside standard cognitive testing.
