Individual Differences in Working Memory Training Outcomes: The Role of Pre-existing Working Memory Capability

These data involved 3 samples of subjects who finished month-long WM visual-spatial span task training and were given either untrained behavioral assessments (the performance of the change detection, 2-back, and suppress task as index) (Sample I) or event-related potential assessments (the contralateral delay activity (CDA) amplitude of the change detection task as index) (Samples II and III) at the pretest, posttest, and 6th month follow-up (the latter for Samples I and II only).
