The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychol...

The purpose of this paper is to clarify the situation and issues of volunteer activities through the example of the students’ voluntary activities after the Kumamoto earthquake. In the case study, we described the volunteer activities of Tokai University students starting from the time immediately after the Kumamoto Earthquake, and the revitalizati...

The purpose of this chapter is to review progress in our understanding of human behavior and decision-making relevant to future earth research agenda, and propose Decision Science as a hub of knowledge networks connecting disciplinary and interdisciplinary sciences with the practice of problem-solving. This review is composed of four sections. Firs...

The category of household and sanitary products is the most important category in the paper industry, because it is related to people’s daily lives all around the world. This category is seeing a rapid increase in consumption, while consumption in other categories, such as printing or writing paper, is presently declining. China is the largest manu...

The 2019 coronavirus disease (COVID-19) pandemic had various influences on people’s ordinary lives, including their thoughts and behaviors related to food consumption. Food waste has been cited as a serious issue with environmental, social, and economic consequences. In this study, we investigated how the COVID-19 pandemic altered the social consci...

The coronavirus disease 2019 (COVID-19) outbreak is threatening not only health but also life worldwide. It is important to encourage citizens to voluntarily practise infection-prevention (IP) behaviours such as social distancing and self-restraint. Previous research on social cognition suggested that emphasizing self-identity is key to changing a...

The eggs illusion is a visual phenomenon in which bright circular patches located at the midpoints between the intersections of a dark grid are perceived as being elongated along the direction orthogonal to the grid line. In the four experiments we report here, we explored the spatial properties of the eggs illusion by manipulating retinal eccentri...

The COVID-19 pandemic began in December 2019 and severely influenced society. In response, the Japanese government declared a state of emergency on 7th April in seven prefectures. The study conducted an immediate survey on 8th April to record the response of the general public to the first emergency status due to epidemics. The study hypothesized t...

The spread of COVID-19 is serious, threatening not only health but also life worldwide. To resolve the crisis, governments need to encourage citizens to voluntarily change their behaviour, such as social distancing and self-restraint. This is especially important in those countries where governments cannot stop people going out, congregating, or at...

Entomophagy refers to eating insects. Insect food, including cooked insects and other processed food with insect-based ingredients, is consumed in many regions of the world as a part of traditional dietary behavior, or as innovative functional food. However, many people especially in western or industrialized societies have shown negative attitudes...

Trypophobia is a strong emotion of disgust evoked by clusters of holes or round objects (e.g., lotus seed pod). It has become increasingly popular and been studied since 2010s, mainly in the West and Japan. Considering this, trypophobia might be a modern emotion, and hence urbanization possibly plays key roles in trypophobia. To address this issue,...

Entomophagy, which refers to eating insects, occurs throughout the world as a part of traditional dietary behavior or as innovative functional food. Insect-based foods are also recommended by the Food and Agriculture Organization as an ideal alternative protein source to address the future potential food crisis. However, many people especially in w...

In the eggs illusion, small patches perceptually deform when placed at the midpoints between the intersections of a regular grid. In this study, we explored the role of orientation processing in the illusion, by manipulating some spatiotemporal stimulus parameters using three psychophysical experiments. In Experiment 1, we manipulated grid luminanc...

In this study, we report a new visual shape illusion, the eggs illusion, in which circular disks located at the midpoints between adjacent grid intersections are perceived as being deformed to ellipses. In Experiment 1, we examined the eggs illusion by using a matching method and found that grid luminance and patch size play a critical role in prod...

In the scintillating grid illusion, illusory dark spots are perceived on white patches at the intersections of gray bars. Previous studies have suggested that processing related to the orientation of the bars plays a role in this illusion, but the specific underlying mechanisms are unclear. In the present study, we investigated the role of orientat...

We report a new illusion in which the edges of diamonds placed at the intersections of grids are perceived to be jaggy (the jaggy diamonds illusion). Interestingly, the illusion disappears when the stimulus is rotated by 45 degrees, when the stimuli are observed at a close distance, and on the diamond at which the observers stare. Luminance contras...

The scintillating grid illusion refers to the illusory perception of black spots on luminance patches at the intersections of a grey grid on a black background. We examined how spatial parameters of luminance patches modulated the strength of the illusion. In experiment 1, we controlled the size and shape of the luminance patches. For the largest-s...
