dc.description.abstract The present study investigated deaf children's performance on several modified tests of the original Halstead Reitan Neuropsychological Battery for Older Children (HRNB-C). Specifically, performance of 42 deaf children (mean age = 13.3 years, SD = 0.7 yrs.) and a matched sample of 42 hearing peers was examined on the HRNB-C Category, Tactual Performance, and Trail Making tests.In Study 1, a computerized version of the Category Test was administered. Step-down F tests were used to examine differences in total errors and the unique contribution of response time. In Study 2, the Tactual Performance and Trail Making scores were dependent variables. Logistic regression analysis was used to explore multivariate intergroup differences.The major finding of this research was that neuropsychological abilities of deaf children who have no additional handicapping conditions or impairments are, in general, similar to matched hearing controls. Few clinically relevant differences were found. No quantitative differences were found on Trail Making Part A or the total number of Category Test errors. Noteworthy, from a qualitative stance, was the role of response time and its unique contribution within the Category Test. Deaf subjects had significantly greater response times to individual items regardless of correctness of answer. Deaf children were also found to take longer on Trails B, although they performed within normals limits. With respect to the Tactual Performance Test (TPT), deaf children did slightly better than their matched hearing peers on TPT total time and location. In addition, Trails B and TPT location scores were the best multivariate composite of discriminators of deaf versus hearing performance. Notwithstanding, overinterpretation of statistical differences found in both studies was cautioned and the similarities of performance between deaf and hearing children emphasized.These findings offered information of deaf children's neuropsychological functioning compared to hearing controls in the clinical setting. Moreover, the results of the present study should be generalizable to other "non-impaired", 12-14 year old deaf children within a residential academic environment. en_US
