| Abstract: | Tracking performances were compared using a differential brightness display (DBD) and a conventional positional display when both displays were moved to the periphery. Results of a previous study and the present study have shown that performance with the positional display was superior to performance with the DBD when the S looked directly at them. As the displays were moved to the peripheral visual areas (15°, 30°, and 45° eccentricity) the reverse of this was true, performances with the DBD were superior. This was reflected both in the actual performance scores and the amount of time S spent looking toward the displays. These results were interpreted in terms of the underlying physiology of the retina and control movements. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
