| Abstract: | Tests purporting to measure attention were administered to college students to examine their relationship to three relatively new tests of attention from the Gordon Diagnostic System (GDS). All subjects received the Standard Delay, Vigilance, and Distractibility Tests of the GDS. In addition, 69 of 136 subjects received the Digit Span, Arithmetic, and Digit Symbol subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), and Kagan's Matching Familiar Figures Test. After the GDS, the other 67 subjects received the Visual Span subtest of the Wechsler Memory Scale-Revised (WMS-R), and the Stroop. Replication (across two studies) and gender influences were not evident on GDS performance. Performance data on this test for these 136 college students, collapsed across replication and gender, are presented. Although within-test correlations were strong, correlations between tests were weak. A ceiling effect on the Vigilance task may have effected its correlations with other tests. Results suggest that the GDS tasks are not substitutes for commonly used tests of attention, but may be useful as an additional source of information in the assessment of attention. |
