Review of the studies on specific training for the remediation of visual field deficits and scotomata due to postchiasmic lesions of the visual system (Zihl & von Cramon, 1979c, 1982) reveals a need to systematically document the improvement of "everyday" tasks such as reading and other behaviours dependent on vision. This study evaluated the effects of light threshold training on visual field functioning, sensory thresholds, grip strength, reading, and tasks thought to evaluate "everyday" vision. Nine subjects were studied over 17 experimental sessions using single-case methods and elements of group methods. The results indicated that light threshold training improves light target detection. There was also evidence that some forms of reading were performed more quickly, though this did not generalize to all reading tasks. As expected, there was no treatment effect on sensory thresholds or grip strength. There was also no treatment effect on formal visual field testing. Finally, there was little evidence on measures of "everyday" vision that light threshold training improved either the speed or performance level on tasks that require vision.Dept. of Psychology.
