项目摘要

An active type mental countermeasure is a countermeasure into which a subject makes a unique reaction occur intentionally to the question irrelevant to an incident to be examined. When a unique reaction occurs to both of questions irrelevant to the question relevant to an incident to be examined, it becomes impossible to find out a difference for the reaction of two questions. Even if the subject is carrying out the false answer to the question relevant to an incident to be examined, it becomes impossible therefore, to detect that. This is the strategy of the detection evasion by the active type mental countermeasure. The dogged nature to an active type mental countermeasure was not examined until now.The research result which lasts [2004] from 2003 is as follows.1.By performing an active type countermeasure, P3 of large amplitude of the same grade as a decision stimulus occurs in the stimulus set as the object of an active type mental countermeasure (CM) non-giving decision. Therefore, when judging also including the reaction to the stimulus for CM, the rate of a detection success falls intentionally by the excited type mental countermeasure.2.If it judges by excepting the reaction to the stimulus for CM, the decline in the rate of a detection success by the active type mental countermeasure will no longer be seen.3.The rate of a detection success may improve by using the information recognized to be more important for a decision stimulus for a subject, making low the degree of discernment of a decision stimulus and a stimulus non-giving decision, and these.

主动型心理对策是指被测者有意地对与被测事件无关的问题做出独特的反应。当两个问题都产生了独特的反应，而这两个问题与要研究的事件相关的问题无关时，就不可能找出两个问题的反应的区别。即使被测者对与被测事件有关的问题做出了错误的回答，也不可能因此而被发现。这就是主动型心理对策侦查逃避的策略。对一种主动型心理对策的顽固性到目前为止还没有研究过。从2003年到[2004]的研究结果如下：在主动型心理对抗（CM）不给予决策的刺激集中，出现了与决策刺激同级的大振幅P3。因此，当判断还包括对CM刺激的反应时，兴奋型心理对策有意地降低了检测成功率。如果将对刺激的反应排除在CM之外进行判断，则不会再看到主动型心理对策检测成功率的下降。通过利用被识别为决策刺激更重要的信息，降低决策刺激和刺激不给予决策的识别程度等，可以提高检测成功率。
