Research Abstract

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.
