Claim 10:
11. A method of evaluating whether a testee is being deceptive, the method comprising:
presenting a set of sentences to the testee, wherein the set of sentences includes an initial sentence and at least three first-type sentences, wherein each of the first-type sentences 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, and wherein the initial sentence is presented to the testee prior to the presenting of the first-type sentences;
monitoring changes in the testee's pupil size during the presenting of the first-type sentences and during any responses to the first-type sentences made by the testee;
comparing changes in the testee's pupil size in response to each of the first-type sentences to ascertain whether a pupil-dilation response to each respective one of the first-type sentences is at least 10% larger than a pupil-dilation response to at least two of the other first-type sentences; and
outputting an indication of deceptiveness or non-deceptiveness for at least one of the first-type sentences based on a result of the ascertaining,
wherein the first-type sentences are all in the same language,
wherein the average volume of each of the first-type sentences is within 10 dB of each other,
wherein each of the first-type sentences has a duration of less than 5 s, and
wherein gaps of at least 3 s are interposed between adjacent sentences within the set of sentences.
