Cognition Over the Lifespan
In our increasingly industrial and crowded society, people are frequently working and living in the presence of unwanted noise. The negative impact of this noise on processing information becomes more noticeable as individuals grow older, in part as a result of age-related hearing and vision loss. In addition to these perceptual difficulties, older adults often report difficulty in remembering information. Recent research has identified a link between perceptual processes such as hearing and vision and cognitive processes such as memory and understanding conversations. This project explores the link between perceptual and memory processes in order to determine how much of the age-related cognitive differences can be traced to perceptual difficulties and how much should be attributed to other causes. The approach will be to measure, control and explain difficulty in understanding and determine its effect on memory performance. To accomplish this, various amounts of visual and auditory noise will be added to stimuli and individual identification functions. Using identification functions, it will be possible to predict memory performance.
