Gettier across cultures.
ゲティア問題の比較文化的検討
Noûs, 1-20.
doi: 10.1111/nous.12110

In this article, we present evidence that in four different cultural groups that speak quite different languages (Brazil, India, Japan, and the USA) there are cases of justified true beliefs that are not judged to be cases of knowledge. We hypothesize that this intuitive judgment, which we call “the Gettier intuition,” may be a reflection of an underlying innate and universal core folk epistemology, and we highlight the philosophical significance of its universality.

Effects of Matching and Mismatching Messages on Purchase Avoidance Behavior following Major Disasters.
東日本大震災後の買い控え低減に向けたメッセージの一致効果・不一致効果の有効性
Psychology & Marketing, 34.

Following major disasters, purchase avoidance behavior toward products that are caused by stigma often results. For example, after the Tohoku Earthquake and Fukushima Daiichi Nuclear Disaster, consumers have avoided products from Fukushima. Attempts have been made to diminish this purchase avoidance behavior, but have been found to be ineffective. The reasons for ineffectiveness of strategies within this context were empirically examined based on matching and mismatching effects of messages. In two studies (Study 1, N = 113; Study 2, N = 364), the effects of affective messages and cognitive messages were compared, and the effectiveness of affective messages was found to be consistently weaker than that of cognitive messages. Message producers often present affective messages with the expectation of observing the matching effect. However, findings suggest that these presentation strategies will fail, and that the mismatching effect should be used instead. The best method of message presentation to reduce purchase avoidance behavior in a disaster area is discussed. 著者（工藤大介）HP: http://dicek.net/

Counteractive control over temptations: Promoting resistance through enhanced perception of conflict and goal value. 
誘惑に対する反作用的統制：葛藤と目標価値の知覚増幅による抵抗の促進
Self and Identity, 17.
doi:10.1080/15298868.2016.1269668

プレプリント：https://osf.io/preprints/psyarxiv/hfhzv The present research explored people’s everyday practice of counteractive control. Experience sampling was used to test our prediction that strong temptations would promote self-control. Participants were 237 Japanese citizens with ages ranging from 18 to 69. Results indicated that perceived temptation prompted stronger resistance and restraint of behaviors, compared to those cases where no conflict was perceived. In addition, multilevel path analysis revealed the underlying process such that (a) a strong desire toward temptation intensified perception of conflict; (b) perceived conflict bolstered the value of goals that were in disagreement with the temptation; and (c) highly valued goals promoted self-control (i.e., stronger resistance and hence less yielding to temptation).

Relationship between Salivary Oxytocin Levels and Generosity in Preschoolers.
未就学児における唾液中オキシトシンレベルと気前良さの関係
Scientific Reports, 6: 38662 
doi: 10.1038/srep38662

This study examined the association between salivary oxytocin (sOT) levels and generosity in preschoolers. Fifty preschoolers played two dictator games (DG) by deciding how to allocate 10 chocolates between themselves and another child, who was either from the same class as the participant (ingroup member), or an unknown child from another class (outgroup member). sOT levels were assessed in saliva collected from the children immediately prior to the DG tasks. While sOT levels were negatively associated with allocations made to both ingroup and outgroup members by boys, among girl sOT levels were positively related to allocations made to ingroup members, and unrelated to allocations made to outgroup members. These results suggest sex differences in the association between salivary oxytocin and generosity.

Individual differences in learning behaviours in humans: asocial exploration tendency does not predict reliance on social learning
（学習行動の個人差: 単独課題での探索傾向は、集団課題での社会情報利用を予測しない）
Evolution & Human Behavior.
doi: 10.1016/j.evolhumbehav.2016.11.001

A number of empirical studies have suggested that individual differences in asocial exploration tendencies in animals may be related to those in social information use. However, because the ‘exploration tendency’ in most previous studies has been measured without considering the information-gathering processes, it is yet hard to conclude that the animal asocial exploration strategies may be tied to social information use. Here, we studied human learning behaviour in both asocial and social two-armed bandit tasks. By fitting reinforcement learning models including asocial and/or social decision processes, we measured each individual’s (1) asocial exploration tendency and (2) social information use. We found consistent individual differences in the exploration tendency in the asocial tasks. We also found substantive heterogeneity in the adopted learning strategies in the social task: Nearly one-third of participants used predominantly the copy-when-uncertain strategy, while the remaining two-thirds were most likely to have relied only on asocial learning. However, we found no significant individual association between the exploration frequency in the asocial task and the use of the social information in the social task. Our results suggest that the social learning strategies may be independent from the asocial exploration strategies in humans.

Media priming effect: A preregistered replication experiment. 
（メディアのプライミング効果：プレレジストレーションを伴う再現可能性検証実験）
Journal of Experimental Political Science, 4(1), 81-94.

Iyengar et al. (1984) discovered the media priming effect, positing that by drawing attention to certain issues while ignoring others, television news programs help define the standards by which presidents are evaluated. We conducted a direct replication of Experiment 1 by Iyengar et al. (1984), with some changes. Specifically, we (a) collected data from Japanese undergraduates; (b) reduced the number of conditions to two; (c) used news coverage of the issue of relocating US bases in Okinawa as the treatment; (d) measured issue-specific evaluations of the Japanese Prime Minister in the pretreatment questionnaire; and (e) performed statistical analyses that are more appropriate for testing heterogeneity in the treatment effect. We did not find statistically significant evidence of media priming. Overall, the results suggest that the effects of media priming may be quite sensitive either to the media environment or to differences in populations in which the effect has been examined.

Increased risk of dementia in the aftermath of the 2011 Great East Japan Earthquake and Tsunami
東日本大震災における被災経験と認知症リスクの関連
Proceedings of the National Academy of Sciences of the United States of America. 
doi: 10.1073/pnas.1607793113.

No previous study has been able to examine the association by taking account of risk factors for dementia before and after the disaster. We prospectively examined whether experiences of a disaster were associated with cognitive decline in the aftermath of the 2011 Great East Japan Earthquake and Tsunami. The baseline for our natural experiment was established in a survey of older community-dwelling adults who lived 80 km west of the epicenter 7 mo before the earthquake and tsunami. Approximately 2.5 y after the disaster, the follow-up survey gathered information about personal experiences of disaster as well as incidence of dementia from 3,594 survivors (82.1% follow-up rate). Our primary outcome was dementia diagnosis ascertained by in-home assessment during the follow-up period. Among our analytic sample (n = 3,566), 38.0% reported losing relatives or friends in the disaster, and 58.9% reported property damage. Fixed-effects regression indicated that major housing damage and home destroyed were associated with cognitive decline: regression coefficient for levels of dementia symptoms = 0.12, 95% confidence interval (CI): 0.01 to 0.23 and coefficient = 0.29, 95% CI: 0.17 to 0.40, respectively. The effect size of destroyed home is comparable to the impact of incident stroke (coefficient = 0.24, 95% CI: 0.11 to 0.36). The association between housing damage and cognitive decline remained statistically significant in the instrumental variable analysis. Housing damage appears to be an important risk factor for cognitive decline among older survivors in natural disasters.

 Younger people, and stronger effects of all-or-nothing thoughts on aggression: 
 Moderating effects of age on the relationships between dichotomous thinking and aggression.
 二分法的思考と攻撃性の関係を年齢が仲介する（若年ほど効果が強い）
 Cogent Psychology, 3(1).
 doi: 10.1080/23311908.2016.1244874

Binary or dichotomous thinking may lead to aggression throughout people’s lifespan; additionally, relationships are likely to be affected by types of aggression (i.e. physical aggression, verbal aggression, anger, and hostility) as well as gender and age. Using large-scale data (N = 2,315), the current study tested if age or gender moderated dichotomous thinking’s correlation with four different types of aggression. Participants (Mage = 36.1, SD = 16.2, range = 18–69) completed the Dichotomous Thinking Inventory and the Buss-Perry Aggression Questionnaire. Dichotomous thinking differentially affected aggression depending on participants’ age: dichotomous thinking and aggression were more strongly correlated in younger participants. Individuals’ tendency to think dichotomously appeared relatively stable; however, age appeared to moderate dichotomous thinking’s effects.

 Online communication with strong ties and subjective well-being in Japan.
 日本人の幸福感と強い紐帯とのオンラインコミュニケーション
 Computers in Human Behavior, 66, 129–137.
 doi: 10.1016/j.chb.2016.09.033

Recent developments in communication technologies have changed how people connect and interact with each other. This study investigates whether and how online communication with strong ties (mobile phone and social networking service [SNS]) enhances subjective well-being in Japan. Study 1 examined whether the correlation between happiness and mobile phone use was mediated by the number of offline and online friends. Study 2 assessed the associations between the Japanese relationship-oriented value “interdependent self-view,” life satisfaction, and the use of SNS. Results indicate that only the use of LINE (an instant messaging application), which is the most popular SNS in Japan, was significantly correlated with life satisfaction and interdependent self-view. The number of friends (offline and online) mediated the effect of LINE use on life satisfaction. Interdependent self-view was significantly correlated with the frequency of LINE use, homogeneity of LINE friends, and life satisfaction. These results indicate that the use of a dominant online communication method with strong ties is significantly correlated with subjective well-being, and this significant correlation is mediated by the number of offline and online friends.

Does a favor request increase liking toward the requester?
頼み事をされるとその人への好意は増すか？
Journal of Social Psychology, 156(2), 211-221.
doi: 10.1080/00224545.2015.1095706

Although a request for help can impose a burden on the provider and has the potential of harming a relationship, the theory of amae suggests that in fact it could help promote a stronger relationship. In an experiment, both Japanese and American participants who were asked for help from a confederate increased their liking of the confederate relative to the baseline. Sociable impression of the confederate and perceived closeness of the relationship also increased relative to the baseline. There was, however, no such increase when participants helped the confederate without receiving a direct request. This study suggests that despite the potential risks to relationships, asking favors can provide opportunities for requesters to build and promote relationships.
