The use of mobile technology affords novel opportunities to mitigate temporal, geographic, and personnel constraints imposed by in-person cognitive testing procedures, and to improve temporal precision by increasing the frequency of repeated assessments. There are, however, technical and logistic barriers that impede widespread utilization of mobile cognitive assessments. I will describe our efforts to overcome these barriers and recent research on validation and application of mobile cognitive tests embedded in ecological momentary assessment (EMA) measurement bursts.
