The PreK EF study, in collaboration with Dr. Michael Willoughby at UNC Chapel Hill, worked to evaluate a set of tablet-based measures of learning and executive function (EF) among a representative sample of children aged 3-5. This battery came to be known as the "EF touch" and is available for public use. More information on the EF touch, the manual, and the battery can be found here:
