SUMMARIZING TECHNIQUES
Lie Detector
Lie detector that works by voice analysis is already widely employed by the police. Psychological stress analyser (PSE) is used by private industry, at least 600 of the devices are used in the US and 3 in Britain. Philip Hicks as assistant manager of Burns Electron Division used PSE and said that one of the other two units was being employed. Dektor emphasises that the device shows only stress, not dishonesty with 3 steps suggested to overcome this difficulty. Hicks admitted that if person showed stress he would assume that the stress was 'indicative of deception'. In US, device is used for pre-employment interviews but now their using the PSE. The potential application of the PSE in Britain the most serious problem also can used to probe a whole range of personal issues. Unions and consumer groups should prevent their use before they become widespread.
