Claim 23:
24. A method of evaluating whether a testee is being deceptive, the method comprising:
presenting an introductory phrase or sentence to the testee;
presenting a set of words to the testee after the introductory phrase or sentence has been presented to the testee, with gaps of at least 2 s interposed between words within the set, wherein the set of words includes an initial word and at least three first-type words, wherein each of the first-type words is expected to evoke significant pupil dilation in a testee who is being deceptive and not to evoke significant pupil dilation in a testee who is not being deceptive, wherein the initial word is presented to the testee prior to the presenting of the first-type words, wherein the entire set of words is presented to the testee in less than 2 minutes, and wherein the set of words contains less than 20 words;
monitoring changes in the testee's pupil size during the presenting of the first-type words and during any responses to the first-type words made by the testee;
comparing changes in the testee's pupil size in response to each of the first-type words to ascertain whether a pupil-dilation response to each respective one of the first-type words is at least 10% larger than a pupil-dilation response to at least two of the other first-type words; and
outputting an indication of deceptiveness or non-deceptiveness for at least one of the first-type words based on a result of the ascertaining,
wherein the first-type words are all in the same language, and
wherein the first-type words all have volumes within 10 dB of each other.
