Study Summary
The investigators will study performance on computerized cognitive tasks in healthy participants of different ages to gather normative data for newly developed computerized cognitive tests. These tests are designed to permit the early detection of individuals at risk of age-related cognitive decline.
Primary Outcome
Multiple behavioral outcome measures will be obtained from each cognitive test including measures of response time (in milliseconds) and accuracy (in percent correct). Recordings of subject's verbal responses will also be analyzed phonologically and automatically transcribed to permit the lexical, syntactic, and semantic analysis of speech output. Questionnaire data will be used to identify factors that may influence performance on the cognitive tests. The primary outcome measures are the scores
