Objective, automated assessment of human information processing

An objective and uncontaminated method for the assessment of capacity to transduce information has been developed, using a portable computer, and is totally self-contained for data acquisition, analysis and reporting. The evaluations conducted are suitable for the literate and illiterate alike, and are brief and nonthreatening. Once an individual has established a baseline grading, the person acts as his or her own control for later evaluations. In this way a person is compared only to a uniquely personal usual and normal state and not to some outside criterion. The system has been validated man-machine operator performance, blood alcohol, patients of externally classified clinical diagnostic categories, and against specific biochemical and bioelectric markers.<>
