Measure of Psychomotor Function Using Speed and Coordination on the CogScreen Pathfinder Number (PFN) Test in Subjects Treated With Alcohol Compared to Alcohol Placebo in Period 1.
時間枠：at breath alcohol levels 0.10%, 0.07%, and 0.04%
|
CogScreen-Psychomotor Edition (CogScreen-PM) consists of a series of computerized cognitive tasks, each self-contained and presented with instructions and a practice segment. The test battery takes about 20-25 minutes to perform. Performance on the test will be measured as the median reaction time for correct responses (PFNRTC) and coordination errors (PFNCOOR) before and after treatment. The measures of the tests are: (a) response speed, the median response time to complete each sequential step (PFNRTC); (b) response accuracy (PF Number Accuracy [PFNACC]); and (c) a coordination measure indicating the respondent's proximity to the center of the target numbers and letters (PF Number Coordination [PFNCOOR]). PF measures number sequencing skills, immediate memory, psychomotor speed and coordination, and visual scanning. The normal range for PFN scores is 1.17-2.16. Scores that are higher than this range indicate some level of psychomotor impairment. |
