title: The relationship of perceptual field orientation to measures of cognitive functioning and current adaptive abilities in alcoholics and nonalcoholics.
abstract: The present study investigated the influence of perceptual field orientation, as measured by the Group Embedded Figures Test (GEFT), on cognitive functioning among alcoholics and nonalcoholics. The subjects were classified as field dependent, intermediate, or field independent based upon their GEFT scores. Cognitive function was assessed by the Wechsler-Bellevue Intelligence Scale as well as the Category Test. Tactual Performance Test, and Trail Making Tests of the Halstead-Reitan Neuropsychological Test Battery. Three primary findings emerged. First, the alcoholics appeared to be significantly impaired on measures of abstraction, problem solving, and adaptive abilities relative to nonalcoholics. Second, a direct relationship was found between GEFT scores and level of cognitive function within both alcoholic and nonalcoholic samples, with field-dependent subjects evidencing the most impaired performance. Third, the level of perceptual field orientation accounted for a large portion of the variance between the alcoholic and nonalcoholic samples, with field-independent alcoholics performing at a level comparable to or greater than other nonalcoholic subroups on a number of the cognitive variables. These results provide validational support for the GEFT and indicate that field orientation may be a relevant variable in the assessment of cognitive function in both alcoholics and nonalcoholics.
