JOURNAL FREE ACCESSThis study examined a relationship between the accuracy of heartbeat detection and physiological measures : heart rate, respiration rate and change in anxiety levels to stress. Fourteen female university students participated in two experiment sessions. In the first session, the accuracy of the heartbeat detection was assessed using a heartbeat detection task. In this task, subjects were asked to judge the simultaneity of heartbeat sensations and continous eight tones at six intervals after concurrent ECG R-waves. In the second session, heart rate, respiration rate and anxiety levels were measured during both rest and a count-down period. Just before the count-down period, the subjects were instructed that they were likely to get a mild electric shock and a strong light flash. Two groupsgood and bad perceivers-were formed on the basis of the result of the first session. These groups did not differ in physiological response and anxiety levels to stress. The results are discussed in terms of an arousal regulation model of emotion.View full abstractDownload PDF (1161K) -

JOURNAL FREE ACCESSReports of various forms of mentation were collected at the wake-sleep transition from 25 female students. Each of 3-min polygraphical records prior to awakening was classified into five EEG-EOG stages, reflecting the variation of standard sleep stages and slow eye movement (SEM) : W (standard stage W with low SEM), D1 (standard stage W with high SEM), D2 (standard stages W and 1 with high SEM), D3 (standard stages 1 and 2 with high SEM) and S (standard stages 2 and 3+4 with low SEM). Sleep perception and sleepiness increased as a function of EEG-EOG stage, and SEM was found to directly relate to sleep perception. Visual imagery was reported at all stages except for stage W, and half of the reports were impressed as dreaming or hallucination and were associated with underestimate of the really elapsed time. The reports of thought showed a wide variety of contents at stages Dl and D2, covering the future-, reality-, and past-oriented ones, whereas it turned into more vague with the content-forgetting predominant at stages D3 and S. Such a chaotic thinking often occurred together with visual imagery.View full abstractDownload PDF (1426K) -
Somatosensory event-related potentials in the discrimination of moving tactile stimuli with pressureYohei NOGUCHI, Kazuo KATAGIRI, Takanori MAESAKO, Rika TAKEGATA, Toshih ...1995 Volume 13 Issue 2 Pages 78-83

JOURNAL FREE ACCESSThe aim of the present study was to examine the evoked potentials which related to discrimination of tactile stimuli with pressure. As a natural tactile stimulus, rotations of brushes were presented to the tip of the right index finger. The rotations were controlled by a stepping motor. Evoked potentials were recorded in two conditions : the non discrimination condition in which subjects were instructed to ignore brush stimuli; and the discrimination condition in which subjects were required to discriminate two directions of stimulus rotations and to count the number of the right rotation. In the discrimination condition, the two direction-stimuli (right : 20%, left : 80%) were presented in random order. N60 appeared dominantly at the regions of C3 and C3'. The amplitudes of N60 for the discrimination condition were larger than those for the non discrimination condition. P300 waves appeared dominantly at parietal region to the right rotating rare stimuli for the discrimination condition. This amplitude-distribution of P300 wave was similar to those of P300 waves to auditory and visual stimuli. This result indicates that P300 waves might reflect the common processing system of multimodal information.View full abstractDownload PDF (744K) -
