1. A method for measuring effects of distraction on a human subject, the method comprising:
- presenting at least one stimulus, at least one visual distraction and at least one audio distraction to a subject;
measuring at least one aspect of at least one of the subject'"'"'s commissions and omissions responsive to said stimulus;
computing an indication of quality of at least one of the subject'"'"'s commissions and omissions when said visual distraction is present; and
computing an indication of quality of at least one of the subject'"'"'s commissions and omissions when said audio distraction is present.

Abstract
A computerized method and apparatus for measuring effects of distraction on a human subject, including presenting at least one stimulus, at least one visual distraction and at least one audio distraction to a subject; measuring at least one aspect of at least one of the subject'"'"'s commissions and omissions responsive to the stimulus; computing an indication of quality of at least one of the subject'"'"'s commissions and omissions when visual distraction is present; and computing an indication of quality of at least one of the subject'"'"'s commissions and omissions when audio distraction is present.

5. A computerized test system comprising:
-
apparatus for measuring a plurality of characteristics of responses generated by subjects; a library of candidate syndromes, each candidate syndrome comprising a set of value ranges for at least some of said plurality of characteristics; and a counter operative to accumulate a number of subjects answering to each candidate syndrome in the library and to provide a syndrome-identified output when the number of subjects answering to an individual candidate syndrome exceeds a predetermined threshold.

6. A system for measuring effects of distraction on a human subject, the system comprising:
-
a presentation generator operative to present to a subject at least one stimulus accompanied by at least one distraction selected from a universe of distractions including at least one visual distraction and at least one audio distraction; and a performance measurement unit operative to measure the subject'"'"'s test performance as affected by at least one audio distraction, to measure the subject'"'"'s test performance as affected by at least one visual distraction, and to compare the two performances thereby to characterize the subject'"'"'s differential response to audio and visual distractions. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 24)

15. A method for measuring effects of distraction on a human subject, the method comprising:
-
presenting at least one stimulus to a subject; generating a reaction time parameter representing the subject'"'"'s reaction time and measuring at least one aspect of at least one of the subject'"'"'s commissions and omissions responsive to said stimulus, other than reaction time; and generating an output characterizing the subject as a function of said reaction time parameter and of said aspect other than reaction time. - View Dependent Claims (16, 17, 22)

18. A method for measuring a human subject'"'"'s performance as a function of at least one stimulus, the method comprising:
-
measuring the subject'"'"'s performance responsive to presence of at least one stimulus displayed on a computer screen thereby to generate a first performance output; measuring the subject'"'"'s performance responsive to absence of said at least one stimulus from said computer screen thereby to generate a second performance output; and comparing said first and second first performance outputs thereby to generate a characterization of said human subject'"'"'s performance as a function of said at least one stimulus. - View Dependent Claims (19)

20. A system for measuring effects of stimuli on a human subject, the system comprising:
a delayed response monitor operative to monitor a subject'"'"'s tendency to respond to a stimulus after the stimulus has terminated.

23. A manufacture comprising a computer-usable medium having computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for measuring effects of distraction on a human subject, the method comprising:
-
presenting at least one stimulus, at least one visual distraction and at least one audio distraction to a subject; measuring at least one aspect of at least one of the subject'"'"'s commissions and omissions responsive to said stimulus; computing an indication of quality of at least one of the subject'"'"'s commissions and omissions when said visual distraction is present; and computing an indication of quality of at least one of the subject'"'"'s commissions and omissions when said audio distraction is present.
