Maximin principle, emotional aversion, and integrative judgment in the NIMBY context, including social dilemma and moral dilemma: The roles of the amygdala, angular gyrus, and ventromedial prefrontal cortex.

Public facilities that have NIMBY (not in my backyard) structure involve both a social dilemma, in which individuals' decisions to prevent the worst outcomes for themselves undermine the public interest, and a moral dilemma focused on the majority versus the minority. This study examined the cognitive-neural processes in judging whether to prioritize the site residents or the citizenry as a whole within the context of NIMBY. Our ROIs were the right angular gyrus being related to concern about the worst possible outcomes for others and oneself, the amygdala associating with emotional aversion to prioritizing the majority, and the vmPFC, which integrates the aversion into "all things considered" judgments. As a result of comparing ingroup conditions for which a NIMBY facility may make participants worst-off position and outgroup conditions for which this possibility is denied, the right angular gyrus was activated in both conditions. The amygdala was activated only in the ingroup, and the vmPFC exhibited a stronger tendency in the ingroup. We concluded that the cognitive-neural processes in judgments on NIMBY facilities are common to both decision-making to avoid the worst-off position for others and for oneself and moral judgments between the majority and the minority.

The effect of habit on preventive behaviors: a two-wave longitudinal study to predict COVID-19 preventive behaviors.

OBJECTIVE: The COVID-19 pandemic is a continuing global threat. This study examined the effect of habit on the motivational aspects of COVID-19 preventive behaviors using a dual-motivation model, which hypothesizes that intentional and reactive motivations determine behavior. This study assumes that habit influences behaviors through the antecedents of the model and the interaction effects of intentional motivation × habit and reactive motivation × habit. DESIGN: This study conducted a longitudinal survey of 300 Japanese participants to predict preventive behaviors two weeks after the first survey. Moreover, it measured past and future COVID-19 self-reported preventive behaviors, attitudes, behavioral intentions, behavioral willingness, subjective and descriptive norms, self-efficacy, behavioral controls, and habits. RESULTS: The results showed the interaction effects of behavioral intention × habit and behavioral willingness × habit on preventive behaviors in addition to the effect of past behavior. The stronger the effect of habit, the stronger is the effect of behavioral intention and the weaker the effect of behavioral willingness. CONCLUSION: The habituation of preventive behaviors strengthens the behavioral intention-behavior consistency. This study suggested that habit is an important factor for overcoming psychological barriers and for establishing preventive behaviors in daily life.

The Influence of Residents' Resilience on the Recovery in the Torrential Rain in Western Japan in 2018.

In 2018 torrential rain caused serious human suffering and damage to property in western Japan. Following such disasters, the investigation of residents' subsequent recovery process is important to determine the support required in affected areas and disaster risk management. This study examines the effects of psychological resilience on residents' life recovery following the torrential rain. We conducted a web survey with 1,000 residents in 13 districts of Hiroshima prefecture and 6 districts of Okayama prefecture that suffered the most damage caused by the torrential rain. The survey used the "recovery calendar" approach to assess residents' life recovery from the disaster. Results indicated that residents who had suffered relatively little damage began to recover during the "disaster utopia" phase up to 2 months after the disaster. However, residents who had suffered serious damage began to recover during the "reentry to everyday life" phase up to 6 months after the disaster. Moreover, older residents or residents with strong psychological resilience who suffered serious damage were likely to recover sooner than those with weaker psychological resilience. Therefore, this study indicates the importance of an approach to disaster recovery according to the level of damage, phased time period, and psychological resilience.

Exposure to diet priming images as cues to reduce the influence of unhealthy eating habits.

A key barrier to changing unhealthy eating habits is the current food-rich environment. Today, there are many palatable food cues that trigger unhealthy eating habits, and once a habit is strongly engrained, it becomes very difficult to change. This research examined the effects of diet priming that is a type of cueing intervention that activates a dieting goal in a tempting situation and thus reduces unhealthy eating behavior in line with the dieting goal. This research was conducted both in a laboratory and in two field experiments. In the three experiments, participants were randomly assigned to conditions where they were either primed by an image of a slim model associated with dieting (priming condition) or were presented with an image of an animal unrelated to dieting (control condition). The dependent variable was the number of snacks that participants took in the laboratory in Study 1 and the number of snacks consumed within the next two weeks in a daily setting in Study 2 and 3. The three studies showed that unhealthy eating habits strongly affect general eating behavior. However, in this research, diet priming changed the influence of unhealthy eating habits and resulted in the decrease of unhealthy eating. Exposure to diet priming cues moderated the influence of unhealthy eating habits triggered by palatable food cues in today's food-rich environment. These findings suggest that diet priming can change habitual reactions to temptations associated with unhealthy eating. Implications for diet priming as an intervention for unhealthy eating habits are discussed herein.

[Consumer's psychological processes of hoarding and avoidant purchasing after the Tohoku earthquake].

This study examined psychological processes of consumers that had determined hoarding and avoidant purchasing behaviors after the Tohoku earthquake within a dual-process model. The model hypothesized that both intentional motivation based on reflective decision and reactive motivation based on non-reflective decision predicted the behaviors. This study assumed that attitude, subjective norm and descriptive norm in relation to hoarding and avoidant purchasing were determinants of motivations. Residents in the Tokyo metropolitan area (n = 667) completed internet longitudinal surveys at three times (April, June, and November, 2011). The results indicated that intentional and reactive motivation determined avoidant purchasing behaviors in June; only intentional motivation determined the behaviors in November. Attitude was a main determinant of the motivations each time. Moreover, previous behaviors predicted future behaviors. In conclusion, purchasing behaviors were intentional rather than reactive behaviors. Furthermore, attitude and previous behaviors were important determinants in the dual-process model. Attitude and behaviors formed in April continued to strengthen the subsequent decisions of purchasing behavior.

Effects of habit on intentional and reactive motivations for unhealthy eating.

This study examined the effect of unhealthy eating habits on behavior within the dual-process perspective, including intentional and reactive motivation. Previous studies assumed that habits elicit behavior directly. However, this study hypothesized that habits affect behavior through their effect on action control and reactive motivation. Longitudinal data were available from undergraduate students (n=286) who completed the first questionnaire assessing their habits, action control (internal and external), intentional motivation, and reactive motivation, and the second questionnaire accessing their actual eating behavior of high-calorie snacks in the 2 weeks following the first questionnaire. Structural equation modeling was used to examine the predictors of their eating behavior. The results showed that habits inhibited internal control and promoted external control. These two sources of control affected intentional and reactive motivations, respectively, which determine behavior. It is concluded that habitual unhealthy eating behavior results from a decrease in conscious control leading to a switch from an intentional to a reactive route.
