Eight subjects were given a pursuit tracking task (Exp. I), a continuous task involving the adding of digits (Exp. II), and the Uchida-Kraepelin psychodiagnostic test (Exp. III). Experiments I and II employed distributed practice. Finger Skin Blood Flow (SBF) and Pulse Rate (PR) were measured during the experiments. It was found that SBF was smaller during trials than during intertrial rests, the latter being smaller than rests with eyes closed. SBF was smallest during the first trial (Exp. I & II) or the first minute (Exp. III). PR reversed direction with some differences being observed between the changes in PR and SBF. The results indicate that concentration on a task is reflected better by SBF than by PR.
八名受试者接受了追踪任务（实验一）、涉及数字相加的连续任务（实验二）以及内田-克莱佩林心理诊断测试（实验三）。实验一和实验二采用分散练习。在实验过程中测量了手指皮肤血流量（SBF）和脉搏率（PR）。结果发现，试验期间的SBF比试验间隙休息时小，而试验间隙休息时又比闭眼休息时小。在第一次试验（实验一和实验二）或第一分钟（实验三）期间，SBF最小。PR的变化方向相反，PR和SBF的变化之间存在一些差异。结果表明，与PR相比，SBF能更好地反映对任务的专注程度。
