This study was conducted to determine if certain types of neurological screening techniques demonstrate more sensitivity to the neurological differences existent among groups of deaf individuals with differing etiologies of hearing loss. The subjects consisted of 40 deaf volunteers, ranging in age from 16 to 20 years, selected on the basis of their etiology of deafness. The assignment of subjects yielded three in situ conditions: rubella, meningitis, and genetic. Subjects were administered the Bender Gestalt Test and the Trail Making Test to determine if significant differences exist among these groups in their performance on these neurological screening techniques. Results indicate that a significant difference exists between etiological conditions based on Part A of the Trail Making Test. A significant difference was found between the meningitis and genetic groups; however, there was no significant difference between the rubella and meningitis groups, or the rubella and genetic groups. There exist no significant differences among etiological conditions on Part B of the Trail Making Test or the Bender Gestalt Test. There was no significant relationship between degree of hearing loss and performance on both Parts A and B of the Trail Making Test or the Bender Gestalt Test. A discussion of results and implications with respect to rehabilitation is included.
