Ecological validity,
the functional and predictive relationship between a patient's performance
on a set of neuropsychological tests and their behavior in a variety of
real-world settings, is emerging as a powerful tool. Since
neuropsychological data were not designed to be ecologically valid,
attempts to use the data in such a manner have been filled with pitfalls.
The authors present a strong argument for reevaluating existing tests
and/or developing new measurements.
Special attention is given to specific functions such as
the cognitive constructs of attention, perception, working memory,
language, and executive function. Additional consideration is given to the
assessment of special populations: children, minorities, substance
abusers, elderly, and emotionally disturbed neurological populations.
One area in which neuropsychology can lend tremendous
assistance is in predicting a client's ability to resume activities of
daily living, but more important, when a client can return to work. Ecological
Validity of Neuropsychological Testing covers this issue extensively
and details the role of vocational rehabilitation and the lack of exposure
many within neuropsychology have to these specific needs of their clients.
