Asymmetric effects of social and economic incentives on cooperation in real effort based public goods games.
努力投入型公共財ゲームにおける社会的・経済的インセンティブの非対称な効果
PLOS ONE, 16(4), e0249217.
doi: 10.1371/journal.pone.0249217

Many practitioners as well as researchers explore promoting environmentally conscious behavior in the context of public goods systems. Numerous experimental studies revealed various types of incentives to increase cooperation on public goods. There is ample evidence that monetary and non-monetary incentives, such as donations, have a positive effect on cooperation in public goods games that exceeds fully rational and optimal economic decision making. Despite an accumulation of these studies, in the typical setting of these experiments participants decide on an allocation of resources to a public pool, but they never exert actual effort. However, in reality, we often observe that players’ real effort is required in these public goods game situations. Therefore, more analysis is needed to draw conclusions for a wider set of incentive possibilities in situations similar to yet deviating from resource allocation games. Here we construct a real effort public goods game in an online experiment and statistically analyze the effect different types of incentives have on cooperation. In our experiment, we examine combinations of monetary and social incentives in a setting aimed closer to practical realities, such as financial costs and real effort forming part of the decision to cooperate on a public good. In our real effort public goods game participants cooperate and defect on image-scoring tasks. We find that in our setting economic and social incentives produce an asymmetric effect. Interestingly economic incentives decreased the share of highly uncooperative participants, while social incentives raised the share of highly cooperative participants.

Cooperation in spatial public good games depends on the locality effects of game, adaptation, and punishment.
空間公共財ゲームにおける相互作用・懲罰・学習の局所効果
Scientific Reports, 11(1), 7642.
doi: 10.1038/s41598-021-86668-3

Despite intensive studies on the evolution of cooperation in spatial public goods games, there have been few investigations into locality effects in interaction games, adaptation, and punishment. Here we analyze locality effects using an agent-based model of a regular graph. Our simulation shows that a situation containing a local game, local punishment, and global adaptation leads to the most robustly cooperative regime. Further, we show an interesting feature in local punishment. Previous studies showed that a local game and global adaptation are likely to generate cooperation. However, they did not consider punishment. We show that if local punishment is introduced in spatial public goods games, a situation satisfying either local game or local adaptation is likely to generate cooperation. We thus propose two principles. One is if interactions in games can be restricted locally, it is likely to generate cooperation independent of the interaction situations on punishment and adaptation. The other is if the games must be played globally, a cooperative regime requires both local punishment and local adaptation.

Source Memory and Social Exchange in Young Children.
社会的交換における幼児のソースメモリ
Cognitive Processing
https://doi.org/10.1007/s10339-021-01028-3

Reciprocal interactions require memories of social exchanges; however, little is known about how we remember social partner actions, especially during childhood when we start forming peer-to-peer relationships. This study examined if the expectation-violation effect, which has been observed in adults’ source memory, exists among 5–6-year-old children. Forty participants played a coin collection game where they either received or lost coins after being shown an individual with a smiling or angry expression. This set-up generated congruent (smiling-giver and angry-taker) versus incongruent (smiling-taker and angry-giver) conditions. In the subsequent tasks, the children were asked to recall which actions accompanied each individual. The children considered the person with incongruent conditions as being stranger that the person with congruent conditions, suggesting that the former violated the children’s emotion-based expectations. However, no heightened source memory was found for the incongruent condition. Instead, children seem to better recognise the action of angry individuals than smiling individuals, suggesting that angry facial expressions are more salient for children’s source memory in a social exchange.

Parental Burnout Around the Globe: a 42-Country Study.
世界の子育てバーンアウト: 42か国調査研究
Affective Science
https://doi.org/10.1007/s42761-020-00028-4

子育てにおいて高レベルのストレスを感じると、親と子の両方に深刻な影響を与える子育て燃え尽き（バーンアウト）症候群になる可能性がある。しかし、親の燃え尽き症候群が文化によって異なるかどうか、また異なる場合、その理由はまだ明らかになっていない。本研究では、42カ国（17,409人の親、71％が母親、Mage = 39.20）における親の燃え尽き症候群の有病率を調べ、国によって親の燃え尽き症候群の有病率が大きく異なることを示した。文化的価値観の分析では、特に個人主義的な文化が親の燃え尽き症候群の有病率と平均値を顕著に高めていることが明らかになった。実際に、個人主義は、国ごとの経済的不平等や、子どもの数や年齢、子どもと過ごす時間など、これまでに検討されている個人特性や家族の特性よりも、親の燃え尽きに大きな影響を与えている。これらの結果は、欧米諸国の文化的価値観が、親に高いレベルのストレスを与えている可能性を示唆している。

How to Read Uncommon Names in Present-Day Japan: A Guide for Non-Native Japanese Speakers.
現代の日本における個性的な名前の読み方: 日本語を母語としない話者への指針 
Frontiers in Communication, 6: 631907.
doi: 10.3389/fcomm.2021.631907

A previous study categorized uncommon names in present-day Japan. However, it was presented in Japanese mainly for native Japanese speakers and thus failed to explain shared knowledge about naming practices, making it difficult for non-native Japanese speakers to understand the study. It is important to share cultural practices not only within but also beyond the culture. Moreover, considering that Japanese names are difficult to read, reducing the risk of failing to read names correctly is helpful especially for non-native Japanese speakers. Therefore, by adding supplementary explanations, this paper systematically describes the characteristics and patterns of uncommon names in present-day Japan. Uncommon names largely take two forms: names with an uncommon reading of Chinese characters and names with uncommon Chinese characters. Regarding the reading, there are three types: 1-1) names that abbreviate the common reading of Chinese characters, 1-2) names that are pronounced as a foreign word, and 1-3) names that are pronounced based on the meaning/image of Chinese characters. Regarding the writing, there are two types: 2-1) names with Chinese characters used infrequently and 2-2) names with silent Chinese characters adding to the semantic meaning without contributing to the pronunciation. Further, a combination of these methods makes names more unique.

People prefer joint outcome prosocial resource distribution towards future others
将来の他者に対しては、総和最大的な向社会的資源分配が選好される
Scientific Reports, 11, 5373.
doi: 10.1038/s41598-021-84796-4

Today, developing and maintaining sustainable societies is becoming a notable social concern, and studies on altruism and prosociality toward future generations are increasing in importance. Although altruistic behaviors toward future generations have previously been observed in some experimental situations, it remains unknown whether prosocial preferences toward future others are based on equality or joint outcome orientations. In the present research, we exploratorily investigated preferences regarding resource distribution by manipulating the time points (i.e., present/future) of the participants and their imaginary partners. The results indicate that prosocial preference toward future others was as strong as that toward present others and seemed to be based on a joint outcome prosocial preference. Notably, when participants and their partners were at different time points, participants preferred to leave resources for the persons in the future. The findings indicate that the type of altruistic preference toward future others may differ from that toward present others, which is mainly equality.

近年、持続可能な社会の構築が大きな社会的課題となっており、その中で将来に対する利他性・向社会性の研究が行われてきています。いくつかの実験では、将来に対する向社会的行動が観察されているのですが、その行動がどのような選好に基づいているのか――具体的には、主要な向社会的選好といわれる平等志向と総和最大志向のうち、いずれに基づくのかは不明でした。 そこで本論文では、自他間の資源分配の選好を測定するSocial Value Orientation Triple Dominance Measure修正版 (Eek and Gärling, 2006)を用いて、自他の時点（現在／将来）を操作した際の人々の選好を測定・比較しました。その結果、現在の他者に対しては平等分配が多く選好されていたのに対し、将来の他者に対しては総和最大分配が多く選好されていました。このことから、将来に対する向社会性は主に総和最大志向に基づいており、主に平等志向に基づく現代の他者に対する向社会性とは異なる可能性が示唆されました。

Left out but "in control"? Culture variations in perceived control when excluded by a close other.
Social Psychological and Personality Science.
doi:10.1177/1948550620987436

Research and theorizing suggest two competing—yet untested—hypotheses for how European Americans’ and Asians’ feeling of being “in control” might differ when excluded by a close other (e.g., a good friend). Drawing on different national contexts (i.e., United States, Japan), cultural groups (i.e., Japanese, Asian/Asian Americans, European Americans), and exclusion paradigms (i.e., relived, in vivo), four separate experiments (N = 2,662) examined feelings of control when excluded by a close- or distant-other. A meta-analysis across these experiments indicated that Asians and Asian Americans felt more in control than European Americans when the excluder was a close other. In contrast, no consistent pattern emerged when the excluder was a distant other. This research has implications for cultural variations in aggressiveness as well as health and well-being following exclusion’s threat to perceived control.

Japanese schoolteachers' attitudes and perceptions regarding inclusive education implementation: The interaction effect between help-seeking preference and collegial climate.
インクルーシブ教育の実践に対する学校教員の態度と認識: 被援助志向性と同僚的風土の交互作用効果
Frontiers in Education, 5:587266.
https://doi.org/10.3389/feduc.2020.587266

While the special needs education system in Japan has shifted from a segregated approach to a more inclusive one, the actual implementation of this approach may be less than ideal. The implementation of inclusive education faces several challenges, such as difficulty in meeting individual needs and lack of medical support systems in general school settings. With this in mind, we conducted a web-based survey of Japanese schoolteachers to empirically examine their attitudes and perceptions regarding inclusive education. We also sought to determine the socio-environmental and individual factors that affect the attitudes and perceptions of Japanese elementary and junior high school teachers regarding the implementation of inclusive education. Survey results showed that schoolteachers regard the idea of inclusive education as desirable, but not feasible. However, we found that schoolteachers’ perceptions of the feasibility of inclusive education implementation were positively associated with their help-seeking preference if they perceived their climate as being sufficiently collegial. Based on these findings, we discuss the educational environment in which inclusive education could be successfully implemented.

Self-compassion helps people forgive transgressors: Cognitive pathways of interpersonal transgressions.
セルフコンパッションは他者への許しに役立つ
Self and Identity
https://doi.org/10.1080/15298868.2020.1862904

This study examined the psychological processes through which self-compassion relates to forgiveness of interpersonal transgressors. Specifically, this study focused on the mediating roles of rumination about interpersonal transgressors and subjective temporal distance from interpersonal transgressions. After completing a measure of self-compassion, participants recalled a time when they were hurt by others. Then, they responded to measures including subjective temporal distance, rumination, and forgiveness. A path model showed that self-compassion was associated with greater subjective temporal distance, lower revenge, and lower avoidance through lower rumination. In addition, self-compassion positively predicted benevolence. Results implied that people with high self-compassion may be less likely to ruminate, which may help them feel greater temporal distance from past interpersonal transgressions and forgive transgressors.
