末梢皮膚温・末梢皮膚血流について,その解剖学的・生理学的機序について論じられた.末梢皮膚血流の調節機構,身体部位による差異,血流量と皮膚温との関係,皮膚血流における周期性変動,生体リズム,男女差,環境温の影響等について概観された.そして,末梢循環計測およびバイオフィードバックを行う上での統制すべき要因として,測定部位,実験室温,被験者特性があげられ,さらに適切な解析時間・測定方法について論じられた.

In the present study we investigated heart rate and heart rate variability (HRV) in the guilty knowledge test (GKT). Participants were instructed to “steal” envelopes and hide them. Participants were then presented with questions focusing on certain aspects of the particular envelopes they had stolen. They were requested to respond with “no” to every question, thus denying their knowledge about the critical items. Heart rate, SCR, and HRV components of high-frequency (HF) and low-frequency (LF) were measured during the GKT examinations. Results showed that heart rate decreased in the critical items. They also showed that decrement of heart rate was most distinctive about 10-15 seconds after the onset of the questioning of the critical items. The results indicated that there is a characteristic response pattern between heart rate and HRV concerning the critical items. That is, heart rate decrement is accompanied by increment of HF component and decrement of LF component. Also, in order to examine which method would serve as the most effective measure for psychophysiological detection of deception, we compared among three different analytical methods: fast Fourier transform (FFT) analysis, peak-to-valley method, and complex demodulation (CDM) method, in assessing HRV, respectively. Results showed that the CDM method traced both HF and LF amplitudes were most effectively, and therefore would be the best indices for detection. Some hypotheses were discussed concerning psychophysiological responses in detection of deception, one of which was the implication that subjects might have adopted passive coping, in other words, hemodynamic reaction pattern-II, when presented with the critical items, because of the particular cardiovascular response pattern shown in the psychophysiological detection of deception.

Twenty-four male participants studied five consonant alphabets. They then performed an Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) that combined a recognition judgment (old vs. new) and a valence judgment (pleasant vs. unpleasant). Faster and more accurate responses were observed when old judgments and pleasant judgments share a same response key than when old judgments and unpleasant judgments share a same response key. These results indicated that the studied items were associated with a positive evaluation. The results were discussed in terms of related phenomena, such as a mere acceptance effect. Some theoretical implications about the relationship between memory and affect were also discussed.

隠匿情報検査では,被検査者が犯罪関連情報を認識しているかを調べる。本研究では,隠匿情報検査において,鼻尖部の皮膚血流量を測った。参加者20名が,犯罪関連項目を認識している条件としていない条件で隠匿情報検査を受けた。鼻尖血流量は,認識がある項目に対して,認識がない項目に対してよりも低下した。この鼻尖血流量の時間的な変化は,隠匿情報検査の既存の指標である指尖血流量とは異なっていた。また,鼻尖血流量により,各参加者の犯罪関連情報に対する認識の有無を有意に正しく判定できた。本研究の結果は,鼻尖血流量が隠匿情報検査の新たな指標になりうることを示している。
