Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In Group B, the investigators will compare the performance of normal participants (N = 100, age range 18 to 89) on computerized and manually administered cognitive tasks.
In Group C, the investigators will gather normative data from participants across the age range (N = 100, ages 18 to 89) for three days at enrollment, to better characterize test-retest reliability scores on Day 1 tasks.
In Group D, the investigators will evaluate the performance of healthy older participants (N = 1200, age range 60 to 89 years) for three days at enrollment and then at 6-month intervals for three years thereafter. In the aim of better understanding health disparities in cognitive testing, this group will be divided into four cohorts: 300 African American participants; 300 Asian American participants; 300 Latino English-speaking participants; and 300 Latino Spanish-speaking participants, who will complete a Spanish translation of our computerized cognitive tests.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Older participant group
We will evaluate the performance of healthy older participants (N = 300, age range 60 to 89 years) for three days at enrollment and then at 6-month intervals for three years thereafter. The goal is to characterize changes in performance to aging and task experience in a group of older subjects.
California Cognitive Assessment Battery
The California Cognitive Assessment Battery (CCAB) is a collection of computerized cognitive tests that will be telemedically administered to participants in their homes using a tablet computer and accessories provided by the research team. Testing may also occur in research laboratories. Previous versions of CCAB tests have been described in 16 manuscripts which describe (a) the psychometric characteristics of normative data collected in large participant populations (300 to 2,300 subjects for different tests) and (b) the sensitivity of CCAB tests for detecting performance abnormalities in patients with traumatic brain injury (TBI) and in control participants simulating the cognitive deficits that follow mild TBI.
CCAB vs. manual test group
We will compare the performance of normal participants (N = 100, age range 18 to 89) on computerized and manually administered cognitive tasks.

Test-Retest Reliability group

Health Disparities group
We will evaluate the performance of healthy older participants (N = 1200, age range 50 to 89 years) for three days at enrollment and then at 6-month intervals for three years thereafter. In the aim of better understanding health disparities in cognitive testing, this group will be divided into four cohorts: 300 African American participants; 300 Asian American participants; 300 Latino English-speaking participants; and 300 Latino Spanish-speaking participants, who will complete a Spanish translation of our computerized cognitive tests.
