Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.
This research study will evaluate how the brain processes language and speech. It will use EEG to determine how brain waves are associated with speech and language. The researchers will combine the information from EEG with MRI images to better understand where in the brain the waves related to speech and language come from.
We are recruiting mothers of children with typical development, autism, or fragile X syndrome.
This study focuses on parental experiences and normal individual differences that may influence child language development. The broader goal of the study is to understand which family experiences support language development in children who have neurodevelopmental disabilities, such as autism. We are recruiting families who have children who are typically developing, have autism, or have fragile X syndrome.
