An Application of Psychomotor Tests to Estimate Worker Performance

Work measurement techniques need to be adapted to apply them to jobs for handicapped workers. Twenty moderately handicapped people from a sheltered workshop performed a battery of 14 psychomotor tests. Photographic methods were used to obtain their times for MTM basic motions on one of the tests and on a light assembly task. A performance index was obtained for each worker for each basic motion and multiple regression equations were derived from the psychomotor tests to estimate these indexes. Predictions from these equations gave gross underestimates of the times for the light assembly task.
