Abstract
Four clinical cases are presented which demonstrate the importance of including the Tactual Performance Test (TPT) in an investigation of a patient's neuropsychological strengths and weaknesses. Each patient's performance reveals interesting quantitative information about the integrity of their cerebral functions. Empirical studies investigating lateralization of cerebral function and TPT performance are cited. The degree to which patients' preferred mode of information processing influences their performance on this test is also discussed. Recommendations are made for an investigation into the qualitative nature of the TPT time and recall phases and implications for neuropsychological rehabilitation are discussed.
