本研究の目的は,事象関連脳電位を指標とした有罪知識質問法は,実験協力者が犯罪関連情報を有していれば,彼らが実際に有罪か無罪かに関係なく,有罪として分類するという仮説を検討することであった。実験1では,模擬犯罪による有罪群に加え,2種類の無罪群を仮定した。一方の無罪群は有罪群の模擬犯罪を目撃することによって犯罪関連情報を取得した。他方の無罪群には犯罪関連情報が一切与えられなかった。P300を検出指標として,犯罪関連情報を一切持たない無罪群は有罪群と弁別できたが,目撃者群は有罪群と弁別できなかった。(以下、略)
The purpose of the present study was to examine the hypothesis that participants with guilty knowledge Test (GKT) regardless of their actual guilt or innocence. In Expeiment 1, two groups of innocent participants were prepared in addition to a guilty group of participants who committed a mock crime. One innocent gourp of participants witnessed the mock crime and thus obtained the same crime-relevant information as the guilty one and the other innocent group of participants had no crime-relevant information. With P300 as a detection index, the innocent group with no crime-relevant information was distiguished from the guilty group but the witnees group was not...
