Abstract
A method for assessing cognitive function in a subject uses a computer having a display, a response sensor and a microprocessor and includes the step of using the display to present to the subject a plurality of items to be analyzed by the subject. The items presented to the subject are intermixed with other of the items being tested for recognition. The method also includes the step of having the subject activate the response sensor after the subject has looked at the display and has recognized the presented items from memory. The subject is tested to determine if the subject recognizes each of the items as meeting a specific criterion. The method further includes the step of using the microprocessor to determine the subject'"'"'s accuracy and his response speed to each of the recognized items. The response speed for each of the recognized items is the time required between when the subject is shown an item and when the subject correctly responds that he recognizes the item.

3. A system to determine the presence of temporary mental impairment for use with a computer having a display, a response sensor and a microprocessor, said temporary mental impairment determination system comprising:
-
(a) an aural generator which generates an aural stimulus in the form of a sound to be heard by a subject; (b) a receiver which receives a vocal response to said aural stimulus from the subject; and (c) a measuring device which measures said vocal response to determine mental impairment of the subject for the ability to safely operate machinery. - View Dependent Claims (4, 5)

6. A computer-executed method for testing neuro-mechanical and neurocognitive function in a subject for use with a computer having a display, a response sensor, and a microprocessor, said computer-executed method comprising the steps of:
-
(a) using the microprocessor to render a test including at least one test module for displaying the test to the subject; (b) using the microprocessor to generate a request for subject'"'"'s input indicative of subject'"'"'s response to the displayed test; (c) using the microprocessor to receive said subject'"'"'s input indicative of said subject'"'"'s response to the test; (d) using the microprocessor to compute at least one subject score as a function of said received subject'"'"'s input; (e) using the microprocessor to compare the at least one subject'"'"'s score to at least one of said subject'"'"'s baseline including a subject'"'"'s baseline wherein said subject'"'"'s baseline includes a mean score and a standard deviation computed from a plurality of subject'"'"'s scores obtained from previously completed tests by the subject; and (f) using the microprocessor to provide at least one of said subject'"'"'s scores and providing the score comparison for displaying to the subject.

22. In a testing session a method for assessing cognitive function in a subject, using a computer having a display, a response sensor and a microprocessor, comprising the steps of:
-
(a) using the display of the computer to present to the subject a plurality of items that have not been seen by the subject previous to the start of the testing session wherein said items presented to the subject are intermixed with repeated items of said presented items; and (b) having the subject look at the display and, after the subject has looked at the display and has recognized one of said presented items as meeting a specific criterion, activate the response sensor wherein the subject is tested to determine if the subject either recognizes said one of said items as meeting said specific criterion or recognizes one of said items as not meeting said specific criterion by not activating the response sensor. - View Dependent Claims (2, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 21, 23)
