“…The "utilization of Japanese Space Food as Japan Disaster Food" is expected to increase the number of "main and/or side dishes" of Japan Disaster Food products. In addition, the Ministry of Agriculture, Forestry and Fisheries' Food Stock Guide for Disasters states that it is desirable to stockpile food for 3-7 days at home (2). The application of space food to disaster foods will lead to "exciting disaster-prevention stockpiling" and can be expected to raise interest in and awareness of disaster-prevention stockpiling (28).…”

Disaster and space environments are similar in that they are closed environment, with limited lifelines. Here, we examined the similarity between disaster food and space food, to explore interactive problem-solving of food support for disaster and space environments. The Japan Disaster Food Certification Standards (Japan Disaster Food Society) and the Japanese Space Food Certification Standards (Japan Aerospace Exploration Agency) requirements and certified products, which were posted on the websites as of June 16, 2021, were compared. Certified products were classified into "staple foods," "main and/ or side dishes," "milk and dairy products," "fruits," "confectionery and favorite beverages," "condiments," "dietary supplements," and "sets." Certification standards involved six items for Japan Disaster Food and eight items for Japanese Space Food. Most standards were similar. Concretely, both standards demanded room temperature storage, tough packaging and hygiene management in facilities. Both emphasized habitual food and easy eating. However, the best-by date was $6 mo for Japan Disaster Food, but $1.5 y for Japanese Space Food. In addition, Japanese Space Food required noted nutritious, food hygienic, eatable in space, cookable by specific equipment, endurable pressure by launch, and domestically produced food. There were 171 and 47 products of Japan Disaster Food and Japanese Space Food, respectively. Staple foods (pregelatinized rice, etc.) and main and/or side dishes were commonest among Japan Disaster Foods and Japanese Space Foods, respectively. It is possible to utilize of Space Food as Disaster Food, but there are some issues that must be cleared before "utilization of Disaster Food as Space Food."

“…In recent years, the need for food stockpiling has increased due to the frequent occurrence of natural disasters and pandemics (1,2). In disaster-stricken areas, in the context of the stress of enforced gathered life and inadequate lifelines, such as electricity and gas, disaster-related foods are indispensable for nutrition to prevent disaster-related deaths.…”

“…Each trait measure consists of two items and participants rated each item on a scale of 1 (strongly disagree) to 7 (strongly agree). The total score for each trait was calculated as described in a previous study [ 29 , 30 , 31 ]. The assessment was conducted before joint go and no-go tasks.…”

Association between Reaction Times in the Joint Simon Task and Personality Traits

Joint go and no-go effects (joint Simon effects; JSEs) are considered to have a stimulus–response compatibility effect on joint reaction time tasks (joint Simon task) caused by the presence of other people. Additionally, JSEs are known to be associated with various social factors and are therefore a potential clinical marker for communicative function; however, the relationship with the personality that is associated with communication skills remains unclear. In this study, we focused on the association between JSE and personality traits. Thirty Japanese participants (fifteen women) were recruited. First, personality trait scores were obtained using the Japanese version of the ten-item personality inventory before the experiment. Second, we measured reaction times in the joint Simon task and single go and no-go tasks with the go signal presented on the congruent and incongruent sides. At last, we analyzed the association between reaction times and personality traits by using Spearman’s correlation analysis. As a result, we observed two pairs with significant correlations: JSE and neuroticism and short reaction times in the joint condition and agreeableness. In conclusion, we identified potential psychological markers associated with the joint Simon task. These findings may lead to an additional hypothesis regarding the neurobiological mechanisms of JSEs.

“…In face of existential and resource threats, some individuals may be more likely to use consumption as a coping mechanism than others [6,12,34]. Accordingly, research during the early phases of the COVID-19 pandemic has shown that a myriad of individual and cultural factors can influence stockpiling: personality [35], high avoidance of uncertainty [36], individualism [36,37], and inability to tolerate stress [38]. In addition to these factors, individual differences in childhood SES [39] might also impact stockpiling tendencies during the COVID-19 pandemic because one's childhood SES has been shown to influence behavior during uncertain situations such as economic recessions and situations that render mortality cues salient [6][7][8].…”

Anticipated scarcity and stockpiling during the COVID-19 pandemic: The role of perceived threat, childhood SES and materialism

Previous research has shown that perceived existential threat experienced during or shortly after the first wave of the global COVID-19 pandemic, engendered anticipated scarcity and stockpiling behavior. However, the relationship between anticipated scarcity and stockpiling may not hold unambiguously for everyone. Across two studies and one preregistered replication (N = 644), we show that perceived threat of COVID-19 is associated with stockpiling tendencies by increasing the anticipation of product scarcity–a resource threat. The association between anticipated product scarcity and stockpiling depends, however, on childhood socio-economic status (SES) and materialism. For individuals with low childhood SES, the anticipation of product scarcity was only associated with stockpiling among those who valued materialism. Individuals with high childhood SES, by contrast, stockpiled in response to anticipated scarcity regardless of their level of materialism. Our findings qualify previous literature on the association between perceived threat of COVID-19, anticipated scarcity and stockpiling during the COVID-19 pandemic and help reconcile contradictory predictions about the role of childhood SES in individuals’ consumption behavior in response to adversity.
