Document Summary

Types of polygraph tests: relevant / irrelevant test (found on slides from lecture) 3 outcomes of the test: truthful, deceptive and inconclusive: overall, most guilty suspects are correctly classified; but a high amount of innocent ppl either had results which were inconclusive or falsely id as guilty (24%) Is not used much, since the cqt is a more quick method and also the media needs to be salient so that only the culprit knows the details of the crime. It is effective in identifying the innocent (95%) and guilty ppl (85%) Validity of polygraph techniques: validity is measured b/w lab and field studies. Can the guilty learn to beat the polygraph: countermeasures: methods used to conceal someones guilt while using a polygraph, countermeasures (physical and mental) both work well, and are not likely to be noticed when someone is using them.
