It is predicted that in the near future robot simulated patients (SPs) will come into use. Through the impressions of five SPs about robot SPs, we explored their vision of the future of medical education as an indicator of what ordinary citizens think. The opinions of SPs were collected using a semi-structured focus group interview, after which the perspectives provided were explored using a qualitative research method called Steps for Coding and Theorization (SCAT). Although SPs accepted the introduction of robot SPs, they regard them as potential substitutes. The use of robot SPs raised concerns about the level of response to human diversity and the level of emotional intelligence. The problem of how much diversity among patients and doctors is acceptable in the field of education was identified. On the part of citizens, there is not much expectation that artificial intelligence (AI) will lead to sophisticated machines capable of human conversation. However, looking ahead to the AI era, real SPs anticipate that, along with the evolution of AI, the next generation of SPs will have thought deeply about their role within a program employing both humans and robots.

International accreditation of medical education was introduced in Japan in 2013 and is planning to be applied in late 2014 or 2015. Students will need to cope with the resulting changes and to recognize by what route they will learn medicine. Therefore, a freshman orientation course, which was based on problem-based learning (PBL) and had been held for first-year students, was modified as an awareness reform program in which students would learn "how to learn medicine." We investigated whether this program has led to useful changes in students' recognition of the way of learning in medical school and their directions as learners. The program was held for 114 first-year medical school students in 2013 and consisted of PBL tutorials, large-classroom lectures, simulation learning using role-play with simulated patients, and team-based learning (TBL), presented in this order. Learning modules that is made with an integration of the clinical sciences with the basic biomedical and the behavioral and social sciences were provided. A nonanonymous questionnaire survey asking "what learning methods are effective for you?" was conducted before and after completion of the course. Furthermore, group answers obtained in TBL were investigated. The score for the question "To what extent can you imagine your route of learning during your 6 years?" significantly increased from 3.1 +/- 0.99 (mean +/- SD) before the course to 3.5 +/- 0.88 (p<0.01) after the course. The score for the question "To what extent is the small-group learning, such as PBL, useful for you?" significantly increased from 3.9 +/- 0.73 to 4.2 +/- 0.71 (p<0.05). Group responses in TBL sessions indicated that students desired classes that presented tasks and regarded "emphasis on reflection" and "observation of senior physicians as role models" as the most important methods for learning interview skills. We believe students should acquire active learning attitudes as adults early in their 6 years of medical school. The level of understanding of "how to learn as adults" was 3.7 and indicated a moderate result. This course employed many educational strategies, and we believe it helped students understand what they learn and how to learn during their 6 years of medical and to get an overview of the learning roadmap.

The purpose of this study is to investigate the characteristics of Visual Evoked brain Potentials (VEP) for application to a new Brain - Computer Interface (BCI) for disabled people with verbal communication disorders such as Amyotrophic Lateral Sclerosis (ALS). In this study, an experiment using VEP recordings was carried out in healthy adult subjects. As a stimuli for the VEP, squared figures were displayed on the LCD of a personal computer. Two experimental conditions that were presented in (1) central visual field and (2) peripheral visual field were used. As a result, two different VEP waveforms were obtained between two stimulus conditions. From a comparison of the VEP waveforms, subjective stimulus position in his/her visual field could be discriminated objectively. Utilizing this phenomenon, VEP based BCI for binary decisions can be constructed. Concerns about the feasibility of this method as a BCI were also discussed. © 2012 IADIS.

In order to estimate the mental workload, electroencephalogram (EEG) was measured during the Figure Stroop Task performance from ten healthy adult voluntary participants. In the experiment, two kind of visual stimuli were prepared: congruent and incongruent stimuli (figure and number of the figure was congruent or incongruent). Participants were asked to answer the number of displayed figures by pressing designated key. In the task, two different instructions to the participants were used: (1) respond as soon as possible, and (2) respond accurately. Integrated theta component of the EEG were compared between under condition of (1) and that of (2). Relative power percentage of theta component in condition (2) was larger than that in (1). The result suggests that the theta component was related with subjective difficulty of the task.

The authors have been studying psychophysiological workload of human interface (HI) with physiological measurements and analysis. In this study, we investigated a kind of mental workload produced by user's unexpected waiting period from the request input to the termination of data processing during personal computer (PC) operation. As the experimental setting of HI, we used interactive software containing easy questions with unexpected time interval between each question. The effects of progress indicator (PI) indicating during waiting period on psychophysiological status of users were analyzed by using respiration, finger plethysmogram (PTG), heart rate (HR) and electroencephalogram (EEG) measurements. Results showed that the theta wave component of the EEG increased in the non-PI condition, even though autonomic nervous system parameters showed no significant change. Negative correlation between preference score for HI and integrated theta component percentage was observed only in non-PI condition. It is supposed that the PI was controlling theta activity coused by waiting stress in experimental condition. Utilizing physiological indices for HI assessment, this experimental method could be available to waiting stress estimation.

In order to obtain a guideline for designing low-workload Human Interface (HI). We investigated assessment of visual fatigue induced by performing an interactive task as a model of HI software on personal computers utilizing measurement of Event Related Potentials (ERP) and accommodation. The ERP were measured in this study before and after a visual target detection task in healthy adult participants to assess visual fatigue of the central nervous system. As an index of accommodation, the ophthalmic near point was also measured using an accomodometer. As the experimental task, participants were instructed to click designated targets from a randomly arranged matrix of characters for one hour. All participants reported symptoms of visual fatigue after the task. From the averaged ERP waveform, P100 and P300 components were detected and their amplitudes and peak latencies were analyzed. Amplitude of the P100 component measured after performing the task was larger than that in the control condition. Near points after the task increased in comparison with those before the task. Results indicated that visual fatigue by the experimental task evoked both eye-strain and altered function of the primary visual cortex. Feasibility of applying the present method to a low-workload software development is discussed.

In order to analyze the autonomic functioning during sleep, polysomnographic measurements including electrogastrogram (EGG) were carried out with healthy adult subjects. The periodic change of the EGG activities calculated from integrated power spectra was not identical to the change of sleep stage. It is suggested that the EGG reflects different aspect of the autonomic profile of human sleep.

To investigate the cognitive aspect of binocular rivalry (BR), an experimental study was carried out using a computer controlled CRT screen. Two square figures filled with different stripes were displayed on the right side and left side of the screen as the BR inducing stimulus. Subjects were instructed to press designated keys for three kinds of received states the right side figure, the left side figure and a combination of them. During the experiment, a continuous line or a non-continuous line as the cue stimuli was displayed on a perceived or a non-perceived visual field. Results showed that the cue stimulus displayed on a non-perceived visual field induced a change in the dominance of BR. Information processing mechanisms for non-perceived visual stimulus are discussed.

To investigate the relationship between sleep rating scales (OSA, KSS) and measured all night sleep EEG, experiments were carried out with healthy adult volunteers. Results showed that the KSS ratings correlated with time percentage of non-REM sleep state. The OSA ratings correlated with waking time in the experimental night. In evaluation of the quality of sleep, some attention should be paid to subjective ratings of the sleep.

In order to assess psychophysiological state of the hyper arousal, pulse transit time during a mental task was analyzed using the ECG R-wave finger plethysmogram onset asynchrony (RPA) measurements. As the mental task, we used the Wisconsin card sorting test (WCST). As the experimental condition, a balloon burst setting with time limit and narration comprehension test were used. Under balloon burst setting experimental condition, measured RPAs were shorter than these in control condition. The result suggested that the RPA is a possible tool for the assessment of panic state through the autonomic responses.

In order to reveal cognitive processing of sensory information in binocular rivalry, visual evoked potentials (VEP) were recorded using pattern reversal stimulus to received side and the other side of visual field. VEP components were observed by evoking stimulus to non-received side of visual field. Results show that the processed information projected to visual cortex does not always generate subjective visual experience.

Three-dimensional perception is based on binocular vision. When different images are presented to both eye, binocular rivalry occurs. The purpose of this study is to investigate the interaction of the 3D-stereovision and the visual conflict caused by binocular rivalry. Ocular dominance was recorded using a personal computer in 3D stereogram with rivalry inducing figures. Our results showed,that under the condition of 3D stereogram with rivalry, the mean rate of fusion time was larger than that in the control condition. The mechanisms of binocular interaction for visual information are discussed

We are apt to be disturbed and make mistakes under psychological and social stresses. This is characterized as the hyper-arousal state. To investigate the physiological aspects of the hyper-arousal state, an EEG and plethysmogram (PTG) were obtained and the pulse transit time was estimated using the R-wave of the electrocardiogram as the starting point of pulsation. Normal volunteers were instructed to shoot a model-gun toward their own heads. The pulse transit time after the shooting was significantly decreased (t<0.002) compared to pre-shooting period. Spectral analysis of the EEG also showed a relevant change in the shooting. Based on these biological indices, one will be able to access the psychophysiological states under certain stresses.
