The University of California, San Diego (UCSD) was awarded a $294,484 Project Grant from the National Institute on Aging (CFDA 93.866 - Aging Research) to investigate the underlying cognitive mechanisms that drive the sensitivity of autocorrection to Alzheimer's disease (AD). The project aims to lay the foundation for developing the autocorrect task as a non-invasive, simple, and low-cost diagnostic tool for early detection of AD. The research combines behavioral and eye-tracking measures to test the attention, monitoring, and syntactic constraints accounts of why individuals with AD or preclinical AD produce more autocorrections compared to healthy controls, particularly for function word targets. Findings from this 2-year project will shed light on how complex aspects of language production are affected by AD in its earliest stages.
