Box and Blocks Tests (VIDEO)

University of Pittsburgh

Caption

This is a classic manipulation box and blocks task, in which the participant is instructed to move small cubic objects from one side of a box to the other by grasping and lifting them over a barrier. With stimulation on, the participant consistently performed better; on day 17 post-implant, she more than doubled the number of blocks transferred when stimulation was off. Her score increased from six blocks without stimulation to 14 blocks during stimulation.
