Aristotle was right: Give me a fixed point, and I will
move the earth. The “earth” in this case is the
urban, semiliterate, nontestwise patient, in particular from
South Africa, with symptoms of mild or moderate head trauma
and in need of neuropsychological assessment. The “fixed
point” does not exist in the form of test given being
the same as test received conceptually with valid norms to go
with it. How then can we move the earth? With justice done to
psychometric requirements and most importantly, to the mental
abilities of the patient, we can not. The neuropsychological
tests normed on Western subjects within the Western cultural
sphere, has put this patient to a disadvantage.
