    Noninvasive techniques for measuring blood flow have recently been of great interest in cardiovascular psychophysiology. Among these, impedance plethysmography is often used for measuring stroke volume and cardiac output (=stroke volume × heart rate) and sometimes used for measuring forearm blood flow. This review describes the basic principles and techniques of blood flow measurement by use of impedance plethysmography in the thoracic and forearm regions. On the basis of the so-called “parallel conductor model” (by J. Nyboer), the equation estimating stroke volume and forearm blood flow is uniformly derived. The importance of obtaining blood pressure is noticed because this enables the calculation of peripheral vascular resistance (=mean blood pressure/cardiac output) and forearm vascular resistance (=mean blood pressure/forearm blood flow). This review is also concerned with systolic time intervals (pre-ejection period, left ventricular ejection time, QS2 or electro-mechanical systole, QT/QS2) : the by-products of impedance plethysmography and the parameters that seem to indicate beta-adrenergic activity. Validities and some controversial problems, as well as the limitations, in relation to these matters are discussed.

    Event-related potentials (ERPs) were recorded during a paired-associate learning task to investigate electrophysiological concomitants of the memory task. Eight college students were presented with a “stimulus” geometric figure and a “response” picture to be memorized (Study session). After the study session, they were asked to recall the “response” picture (Recall session). Both the Study and Recall sessions had four blocks. During the Study session, ERPs were recorded as a pair of stimuli. The number of recollected “response” pictures increased along with the repetition of the block. The P300 component of ERPs following the second of a pair was maximal in the parietal area. The amplitude of P300 increased and the peak latency of P300 decreased with repetition. These results suggest that P300 was sensitive to memory acquisition and racall processes. Increased positivity observed in ERPs evoked in paired-associate learning tasks results not only from the enhancement of late positive components, but also from the attenuation of negative-going components.

    In order to measure eye-head coordination in children, an apparatus for measuring head movements was developed by a sensor of terrestrial magnetism. The sensor on a head detects terrestrial magnetism which relates to the change of direction of head. The sensor was so light weight (100g) that there was no difficulty in installing the sensor on head of a child. The eye movement was recorded by the horizontal electrooculography. Trajectory of gaze was accurately constructed from summation of movements of eye and head. Applying this apparatus to a child of 6 years of age, characteristic pattern of head and eye movement was found during shifts of gaze to targets beyond the oculomotor range. Results indicate that the present apparatus is effective in measuring precisely eye-head coordination of children.

    This is the summary of the presidential address delivered at the 11th Annual Meeting of JSPPP at ICU in June, 1993, which discussed, with an appeal to our younger members for serious concerns, on four topics as follows : 1) the very nature of physiological psychology as the core of the mind-body problem, 2) the relationships between the speaker's researches and some theoretical models, 3) the significance of physiological psychology in the curriculum development for undergraduate program, and 4) the new roles of JSPPP as an academic society for the future.
