Dostoevsky’s enigmas: An analysis of violent men

For the calculating male adult criminal, violent acts would appear largely counterproductive. Scholarly disagreements about these behaviors are substantial, although recent ethnographic reports emphasize the subjective sense of the experience. These reports have an existential aspect, focusing on the meaning of violent, anarchic acts to the identities of perpetrators. The earliest and best known existentialist writer on criminality is Fyodor Dostoevsky whose violent characters Smerdiakov, Svidrigailov, and Stavrogin, are enigmas to their fictional counterparts, much as violent American contemporaries are to authorities and the general public. Dostoevsky’s three enigmatic characters are reckless publicity seekers; like aliens in their own land, they habitually deceive, intimidate, and exploit while still considering themselves to be decent individuals. These depictions are congruent with Yochelson and Samenow’s much more recent forensic observations and reinforce an antisocial prototype. Bogg (1994) offers a behavioral communality for this class of violent men: patterns of self-aggrandizing gaming developed in childhood. The game player derives extraordinary pleasure from victories, although this orientation effectively counters socialization. From Dostoevsky’s views an existential nihilistic construct can be derived. This construct depicts the persona of an inveterate violent game player and is consistent with Durkheimian theory and with ethnographic and forensic/clinical observations. The prevention of a gaming orientation is feasible but appears to require parental skills and community resources.     

Unequal but not separate: Emergence of rich–poor cooperation in resource exchange

Addressing inequality is a critical challenge for society as a whole and requires sustained efforts to promote fairness and opportunity for all. Filling in the resource gap across social classes is essential in reducing inequality. Previous studies have revealed that ingroup favouritism hinders the rich from cooperating with the poor and expands the wealth gap. Nevertheless, how to find ways of narrowing the gap between the rich and the poor remains an open question. Inducing rich–poor cooperation could be effective in eliciting resource flow across classes. In this study, two experiments using a modified Prisoner's Dilemma game were conducted in Japan (N = 213) and China (N = 150) to examine whether highlighting partners' cooperativeness under permeable group boundaries induces rich–poor cooperation. All participants were allocated to the rich group and participated in the game with programmed rich- or poor-group partner bots, whose cooperation rates were manipulated. Despite the initial resource disparities between participants and the partner bots, participants were more likely to select and cooperate with cooperative poor-group partners than with non-cooperative rich-group partners. Generalized trust played an important role in the enhancement of rich–poor cooperation. The findings shed light on the possibility of reducing inequality and promoting social mobility in society.     

What Game Is Being Played? The Need for Clarity about the Relationships Between Scientific and Theological Understanding

This paper investigates the relationship between theology and the natural sciences by considering four realist and five nonrealist interpretations of theological understanding. These are that theology expresses biblical affirmations, the faith of the community, revelatory declarations, or a prioriconclusions, and that it is reducible to expressions of feelings, attitudes, naturalism, liberating praxis, or moral convictions. Because these views are unsatisfactory, the author calls for an imaginative form of natural theology that shows how faith's understanding of the purpose, value, and meaning of reality fits how the world is actually found to be.     

Does fear modulate defensive and offensive types of maternal attack in mice?

Swiss CD‐1 lactating mice show a different pattern of attack toward intruders of differing sex, displaying defensive attack against the male (bites on the head and ventrum associated with fear) and offensive attack against the female (bites on the back and flanks with no elicitation of fear). This dichotomy may reflect diverse functions of maternal aggression: the attack toward males (the more infanticidal gender in laboratory strains) has been interpreted as a counterstrategy to infanticide, whereas the attack toward females may serve to establish a social hierarchy or to space rivals of the same sex. In terms of proximal mechanisms, fear may be a key factor involved in the modulation of the different patterns of attack. In Experiment 1 we compared the pattern of attack of lactating females in Swiss CD‐1 and Wild mice toward male and female intruders in relation to fear components of behavior of the attacking dams. Results showed that in Swiss mice, male intruders were attacked with a defensive type of attack accompanied by high levels of fear, whereas female intruders did not elicit fear in the attacking animal but were attacked with an offensive pattern. In Wild mice, both types of intruders were attacked with a defensive pattern; notwithstanding, fear was evident only toward male intruders. This suggests that fear is not totally responsible for the expression of the defensive type of attack. To test the hypothesis that defensive attack toward male and female intruders may be related to the infanticidal potential of the intruder, Experiment 2 examined levels of infanticide in both male and female Swiss CD‐1 and Wild mice. Swiss female mice showed virtually no infanticidal behavior, whereas Swiss males and both sexes of Wild mice showed similarly high levels of infanticide (55%–75%). From a game theory perspective, the defensive pattern of maternal attack toward female intruders in Wild mice is discussed as “extreme” defense of a high value resource and thus, functionally, a competitive form of aggression.

亲社会视频游戏中的合作对博弈决策中合作行为的影响

以38名大学生和研究生为被试,采用Chicken Game实验范式测量合作行为,考察了单人和双人合作模式游戏后,性别和游戏习惯对玩家在博弈决策中合作行为的影响。结果表明：（1）双人合作模式游戏可以促进玩家在博弈决策中的合作行为;（2）双人合作模式游戏后,男玩家（相比女玩家）在博弈决策中的合作行为更多;（3）玩游戏的习惯影响博弈决策中的合作行为,相比于经常习惯与现实朋友玩游戏和独自玩游戏的玩家,经常习惯与网友玩游戏的玩家在双人合作模式游戏后的合作行为更多。本研究不仅证实了一般学习模型,也证实了亲社会合作类视频游戏可以有效促进博弈决策中的合作行为。     

诚实-谦逊性和人际亲密性对公平规范执行的影响

采用2（诚实-谦逊性：高分组、低分组）×3（人际亲密性：家人、朋友、路人）×2（提议不公性：高不公提议、低不公提议）的混合实验设计,考察人际冲突情境下诚实-谦逊性与公平规范执行中人情效应的关系。研究结果发现,随着人际亲密性的增强,人们对互动同伴的互惠预期越高,更倾向于接受不公提议;高、低诚实-谦逊者付诸公平规范执行时均会考量双方彼此的人际亲密性,但高诚实-谦逊者存在更强的人情效应。结果表明,高诚实-谦逊者更在意维持有价值的人际关系,愿意宽容重要他人的违规行为。     

To be at the tail of the lions or the head of the foxes?

Agents seeking an opportunity for profit often have to compete with others who pursue the same opportunity. When having to choose between a number of opportunities differing in their value and if individuals differ in their chances of outperforming others, the choice can be cognitively and emotionally demanding. We explore choice between opportunities using stylized Lions–Foxes games. In such a game, each of three players, with different odds of beating others, has to choose one of two contests that offer different rewards. After game theoretically analyzing the games, which we have experimentally employed, we report four experiments that vary in choice elicitation (repeated play or strategy method), in players' matching (random strangers or partners) and in rewards. Regarding contest choices, we found the choice of the higher value (and seemingly more prestigious) contest to be positively related to winning odds, contrary to what four out of the five (mixed, partially mixed, or pure) equilibria predict. Participants started out rather optimistic, with a large majority choosing the higher value option, but with experience, they approached the only viable of two pure strategy equilibria. Still, mixing continued via reacting to past play and outcome, apparently balancing dissatisfaction from choosing either contest.
