JOURNAL FREE ACCESSThe amplitude of a late positive wave (P3 or P300) of the event-related brain potential (ERP) elicited by probe stimuli in a secondary task is inversely related to the amount of perceptual-central processing resources allocated to a primary task. The historical overview of this theory is discussed and a selective review of the probe stimulus technique using ERPs is presented. Then, an extension to the study by Suzuki, Nittono, and Hori (2005, International Journal of Psychophysiology, 55, 35-43) is reported to demonstrate that the amplitude of the P300 elicited by auditory probe stimuli varies with the level of interest in video clips, even when their perceptual complexity is equivalent. More specifically, P300 amplitude was smaller when participants watched a video clip for the first time than when they watched the same video clip for the fifth time. Moreover, the amplitude reduction was more prominent for the P300 elicited by perceptually deviant, non-target probe stimuli than for the P300 elicited by target probe stimuli presented with an equally low probability. The potential merits of the probe stimulus technique using ERPs in non-occupational settings are discussed.

JOURNAL FREE ACCESSHow a sound's physical factors influence brain activities was investigated by magnetoencephalography (MEG). If we can understand how sensory information is processed in human, the knowledge can be put to practical use designing preferable environments and products. Auditory evoked fields in relation to pitch saliency and subjective diffuseness were evaluated by N 1 m responses on MEG. The results indicated that the magnitude of N1 m decreased with decreasing pitch saliency and subjective diffuseness, which are influenced by repetitive components included in sound and binaural correlations. This is a hint that these factors should be considered in evaluations of auditory environments. Subjective preference for sound fields were evaluated by factors extracted from the autocorrelation function (ACF) and the crosscorrelation function (CCF) of MEG alpha band (8-13 Hz). Effective duration of the ACF and the maximum value of the CCF corresponded well to subjective preferences; thus these factors appear useful for evaluations of human environments as objective measures.

JOURNAL FREE ACCESSIn Nature Psychophysiology, physiological responses to nature elements that make us comfortable are measured and analyzed. The results of this investigational procedure are used to create some comfortable environment and/or products that provide human well-being. This is Tranquility Ergonomics. In this article, physiological characteristics of human responses, definitions of comfort and pleasure, and the biophilia hypothesis by which human innate responses to the nature is conceptualized are reviewed. Some research results obtained by the author are also reviewed and strategies to evaluate human comfort are discussed.

JOURNAL FREE ACCESSThe purpose of this article was to innovate the concept of “KANDO” for product development in industrial activity. Summarizing the history of the product concept in Japan, “KANDO” was proposed as a new concept inevitably. “KANDO” is the Japanese everyday term of intense emotional state that could be evoked by surprising-, impressive-, exciting-, and/or thrilling experiences. We hypothesized the process of “KANDO” as shown in Figure 1; i.e., (1) indifference, (2) passive attention, (3) active attention, (4) recognition / internal attention, (5) evocation of emotion, and (6) experience of “KANDO”. As some stages in this hypothetical process might be indexed by physiological response measure as shown in Figure 1, we can assess “KANDO” directly by means of psychophysiological technique established in past one decades.

JOURNAL FREE ACCESSThe present review discusses why multi-neuronal recording is requisite to detect real features of information processing in the working brain. We introduce several technical key points and to-be-solved problems in the recording experiments. Then we refer to “cell-assembly”, ensemble activity of functionally connected neurons, as a functional unit representing neural information in the brain. Several relevant points concerning detection of the actual dynamics of cell assemblies are enumerated. Finally we introduce a rapidly growing research subject, brain-machine interface (BMI). It tries to detect and utilize neural information by cell assemblies in the working brain to operate artificial devices instead of the animal or human bodies. Multi-neuronal recording and analyzing systems detecting actual cell assemblies are keys to construct successful BMI. We finally show a newly developed and high performance system for our BMI research, which can detect precise submillisecond activity interactions among closely neighboring neurons in the behaving animal.

JOURNAL FREE ACCESSIn psychophysiological research, many machines are used to measure physiological phenomena. The purpose of the present paper was to review researches on original machines for psychophysiological research developed in the author's laboratory. The first series of examples are systems to measure and analyze unique event related potentials (eye fixation related potential, EFRP) associated with offset of saccadic eye movements. We have developed some types of real time topographies for EFRP that changes with psychological phenomena. We also developed a prototype of an impedance CT to estimate the blood flow in the brain. The second series are biofeedback systems for clinical and industrial purposes. The third series are a word processor operated by with EMG and EOG activities for handicapped persons. A new approach is expected to develop an original machine to measure physiological phenomena from a viewpoint of psychology.
