    On a CRT display, analogue heart rate feedback of each beat was presented together with a target calculated from a subject's heart rate level. Twenty subjects received twenty-four 100-beat trials. All subjects were required to continue adjusting their heart rate around the target as close as possible under both immediate and 3-beat delayed feedback conditions. Half of the subjects received immediate feedback trials first, followed by delayed feedback trials, while the other half received trials in the reverse order. Results indicated that feedback delay disrupted the accuracy of heart rate control when subjects received delayed feedback after immediate feedback trials, and that feedback delay caused low-frequency oscillation in heart rate variability. Findings in this experiment suggest that voluntary control of heart rate can be understood from the viewpoint of motor skills learing.

    This study was designed to examine whether the subjects could learn to discriminate their alpha activity from non-alpha activity by integrated alpha technique. A total of 26 subjects were assigned to either the experimental group or the yoked control group by pair-matching the amounts of alpha wave. Both groups received three 5 min feedback training sessions to increase the alpha activity. In these sessions, the experimental subjects were given contingent feedback signals to their amount of alpha wave, while the control subjects were given non-contingent feedback signals. In the pre-and post-feedback sessions, the subjects' discriminabilities of alpha activity, either presence or absence, were measured 60 times respectively. The results showed that the experimental subjects significantly improved their discriminative accuracy across the trials, although the yoked control subjects provided no improvement of accuracy. Noteworthily, the experimental subjects significantly increased their amount of alpha wave during the feedback sessions.

    本研究は,SPAに及ぼす電極圧迫の影響と性差を検討する目的で行われた。被験者として,大学生20名(男子10名,女子10名)が用いられた。
    電極圧迫によってSPAは以下のような影響を受けた。
    (1)SPLは圧迫直後に急激に低下したが,そのの後は変化に乏しく,非圧迫指と比較してSPL値は高くなった。
    (2)SPRについては,頻度の減少および二相性波・陽性単相波の陰性単相波化が認められた。また,振幅についても,陽性成分の減少が認められた。
    このような結果が得られた主要因として,(1)圧迫による汗口閉鎖,(2)皮膚圧-発汗反射による反射的発汗抑制,(3)圧迫によって2次的に生起する血行障害,が考えられた。
    SPAの性差も顕著であり,以下のような結果が得られた。
    (1)SPLは,女性に比較して男性の方が高かった。
    (2)SPR頻度も男性の方が多く,振幅については,陽性成分に関してのみ,男性の方が大きい傾向が認められた。
    これらの結果から,EDAを指標として行う研究において,男女混合の被験者群を構成することは避けられるべきであることが示唆された。

    A system named Automated Spindle Analyzer (ASPA), which automatically detects sleep spindles and measures the mean amplitude, the mean frequency, the duration and the time of occurence of each spindle in real time, is described. It can also calculate the means, standard deviations and distributions of each parameter across the recording. Furthermore, it is possible to control experiments concurrently with analyzing sleep spindles by the system. Agreement between spindle detections obtained by visual scoring method and by the ASPA was relatively high; approximately 90%. The ASPA has advantages of low cost, portability and self-sufficiency. The utility of this system thus recommends it for the analysis of sleep spindles in laboratories and various other circumstances as well.
