TESTING DEVICE FOR HYPERACTIVITY IN CHILDREN Abstract A device is disclosed For use in assessing the ability of a child to sustain his attention over a period of time, which information can accurately differentiate between hyperactive and nonhyperactive children. In one embodiment, the device (10) sequentially displays (14) a plurality of numbers and the child is instructed to push a button (20) each time the number "9" appears. The device records each correct response (40), each time the child omitted a response (44) and each time the child committed an error (42) by pushing the button (20) at an improper time. In a second embodiment, which is in- tended for older children, the child is instructed to push the button (20) only if a "1" appears and is then immediately followed by a "9". Again, the number of cor- rect responses are recorded as are the number of errors of omission and commission. In both embodiments, the test is divided into three separate time blocks (18) and the child's responses are recorded separately for each block. The delay time between the display of each of the numbers can be adjusted (16) and different delay times can be preprogrammed for each of the three separate time blocks.
