The Wayne State executive function data set (collected on 1.5T Signa (GE) scanner), comprises 112 extensively-sampled healthy individuals. The overarching aim of the executive function study is to explore the mediating role of differences in brain structure, executive functions (EF), and processing speed in age-related differences in episodic memory. The primary goal of this study was to establish whether age-related differences in episodic memory could be explained by age-related deterioration of the relevant brain structures and declines in cognitive operations that are considered more basic than episodic memory, that is, speed of processing and various executive functions (EF). All participants were screened at baseline via a health questionnaire for the following conditions: presence of cardiovascular, neurological, or psychiatric disease, use of centrally-acting medications, the habit of having three or more alcoholic drinks per day, as well as being minimally high school educated, native English speakers.

All participants underwent cognitive testing,and although the composition of testing batteries varied across cohorts, some tests are common to all: Cattell Culture Fair Intelligence Test, various forms of multiple-choice vocabulary tests (Educational Testing Service), tests of episodic memory and working memory. Cognitive variables are available to qualified investigators upon request.

This set of imaging data (T1 MPRAGE) have been collected on a 1.5T Signa (GE) system.
