Heartbeats (HB) 検出力に及ぼすHB弁別訓練と結果の知識の効果

抄録

The main purpose of this study was to examine the effect of heartbeats (HB) discrimination training as well as the knowledge of results (KR) on the accuracy of HB detection. The accuracy of HB detection was assessed by pre-test, four training blocks, and post-test, using Katkin's HB detection technique, which is based on the theory of signal detection. Twenty subjects were assigned to either KR or non-KR groups. The KR group was given the knowledge of results during the four training blocks. The results showed that the KR group tended to show greater accuracy of HB detection than the non-KR group. The following two points were also analyzed and discussed in this paper : (1) Whether or not the level of HB detection on the pre-test influenced the four training blocks and the post-test. (2) What was the relationship between the subject's own understanding of his or her method of HB detection and the level of HB detection.
