JOURNAL FREE ACCESSIn order to investigate the effects of active and passive processing of apparent motion perception on visual evoked potential (VEP), two experiments were conducted in which point-lights walkers were presented intermittently at the rate of 3 Hz as stimuli. The point-lights walker was composed of only 10 point-lights represented main joints of a human walker, and in intermittent presentation apparent motion of those point-lights was perceived. In Experiment 1, participants discriminated four stimuli, which were forward walk (FW), backward walk (BW), random walk (RW) and static sequence (SS), so that active processing was examined. In Experiment 2, passive processing and task loads were examined by using RW and SS. In both experiments, five VEP components were found for motion stimuli (FW, BW, RW), N60, P 120, N 185, P210 and N280. By comparisons between experiment 1 and experiment 2, it was suggested that N60 and P210 reflected active motion perception such as tracking of point-lights, and that N280 reflected both passive motion perception and task loads.View full abstractDownload PDF (1381K) -

JOURNAL FREE ACCESSThe present study was designed to investigate the effects of interest and auditory modality on the spontaneous eyeblink during watching music video films. Twenty female participants were recruited from the university population and instructed to watch two kinds of the music video stimuli. One stimulus consisted of a popular music scene played by a Japanese famous rock-music group (high interest stimulus) and another stimulus consisted of a music scene played by an unfamiliar artist (low interest stimulus). In addition, each of these visual stimuli was presented with and without sounds (i.e., the sound-added condition and the sound-deprived condition, respectively). The spontaneous eyeblink rates significantly decreased in the high interest stimulus as a function of the degree of interest. On the other hand, the spontaneous eyeblink rates significantly increased especially when the low interest stimulus was presented without music. The results indicate that the spontaneous eyeblink rates are influenced by the interaction between degree of interest and music addition.View full abstractDownload PDF (1106K) -

JOURNAL FREE ACCESSIn the present review, biobehavioral factors in ambulatory blood pressure (BP) monitoring were assessed from a psychophysiological standpoint. First, the validity of ambulatory BP was investigated, and problems with measurement errors were clarified. Second, behavioral diary and actimetry were assessed in terms of the degree to which they enable us to interpret BP variations, and some demerits, especially regarding the reactive nature of the behavioral diary, were pointed out. Third, 24-hour long-term BP variations were interpreted as diurnal variations rather than circadian rhythm. Fourth, category/option and episode were advocated as two sorts of conceptual frames to analyze a diversity of BP variations, whether long-or short-term, and some examples from typical studies were presented using the frames of reference, underlying the influence of biobehavioral factors. Fifth, some intriguing ambulatory studies using parameters besides BP were appraised, and finally, the promising nature of ambulatory psychophysiology was discussed.View full abstractDownload PDF (2488K)
