As you age, cognitive abilities like memory and planning will decline. Older adults will have a harder time formulating speech by seeing slower speech with more pauses, fillers, and circumlocutions compared to their younger years. In this study, we will look to analyze the participants’ phonological neighborhood densities, the sounds of words, with MRI methodology. By looking at their PND, we can see how aging plays a role in their speech, speed, planning, and retrieval.
