| Our findings thus far show that the sanction reduced the number of chips that participants allocated to themselves and that it only increased the number of chips allocated to the yellow pool when there were two options.,1 | |
| "Thus, whereas at first sight guilt merely indicates the presence of a repentant transgressor, other group members may indirectly profit from this emotional display because it may lead third parties to evaluate them as prosocial.",1 | |

| "This missing piece of information may lead subjects to estimate their counterparts' reputation to be lower than what they would do with more information, and therefore to decrease their cooperativeness.",1 | |
| "First, we can assess the correlation between beliefs and contributions, which we expect to differ between types of players and which helps us to check on the player type as elicited in the P-experiment.",0 | |
| "First, it is possible that a cooperative strategy reduces greed because greedbased actions are frequently justified through defensive assertions.",1 | |
| "Instead, I opt to take advantage of the natural tendency toward free-riding by increasing the number of periods prior to each stoppage while fixing the total length of the experiment.",1 | |
| We also conducted sessions with homogeneous groups of Colombian and American students to control for and compare base levels of cooperativeness in the two settings.,0 | |

| Gumballs were used because their round shape allowed them to roll down the ramps in the apparatus.,1 | |
| Fehr and Leibbrandt (2011) found that fishermen in Brazil who are more cooperative and patient in lab experiments are also less likely to exploit the common pool resource in the sense that they use shrimp traps with bigger holes (where small shrimp can escape) and fishnets with larger mesh sizes (where only bigger fish are caught).,1 | |
| "Therefore, significant t-values in the models indicate that expectations significantly affect the probability of cooperation.",1 | |

| "Akerlof (1980) and Romer (1984), for example, argue that social customs are maintained by the social sanction imposed by loss of reputation when breaking the custom.",1 | |
| The result suggests that cooperative play in video games-whether violent or not-has the potential to improve cooperation in different circumstances.,1 | |
| "Upon entering the laboratory, the subjects were randomly assigned cubicles in which they were seated.",0 | |
| "A demand for behavioral norms arises when members of a group have individual incentives to take actions that reduce the group's overall welfare (James S. Coleman, 1990).",1 | |
| In other words such a player would be unwilling to receive an S payoff very often.,0 | |
| "Implicit evaluations are not only sensitive to individuals' goals, but also to situationally variable affordances.",1 | |
| Previous studies often show that unrestricted punishment can promote cooperation in public goods environments although restricted ones are more effective.,1 | |
| "One possibility would be that greedy people's continual striving for more would make them more sensitive to the magnitude of outcomes and less to the associated probabilities, leading to more risk taking.",1 | |
| "Thus, it is to be expected that the discontinuity eect will remain but will be reduced more in the successive than in the more uncertain simultaneous condition.",1 | |
| "The present findings fill this gap and, by so doing, suggest that groups are more competitive than individuals not simply because the intergroup context (and not the interpersonal context) renders salient group morality but because each context renders salient its own unique moral code, with group morality producing competition in intergroup interactions and individual morality producing cooperation in interpersonal interactions.",1 | |
| "Communication provides greater opportunity for cooperation, but that opportunity may either not be used, ineptly used, or used for deceit and vituperation [p. 22].",1 | |

| "The use of rewards and punishments is usually proposed as a means to promote cooperative choice behavior (Hardin, 1968;Olson, 1965).",1 | |
| "In this standard design, increasing m has two effects: first it increases the return to others from contributions to the public account, and second it lowers the private cost of those contributions.",1 | |
| Thus if subject A is more co-operative than B he will tend to lose in this situation.,1 | |
| "Therefore, institutional incentives are more powerful than peer incentives in promoting cooperation because the incentive institutions work although not all defectors are punished.",1 | |

| "If the decision maker faces a finite number of possible opponents, the rule is incentive compatible in the cases where her subjective expectation corresponds to one of the outcomes that the aggregate choices of her opponents could possibly generate, but it is not incentive compatible for all possible beliefs that could be stated.",1 | |

| "Accordingly, it is unclear whether the priming manipulations in those studies altered such perceptions, and if so, what associations there were between the relevant perceptions and the dependent measure.",0 | |
| "Although findings on this topic have been controversially discussed (e.g., Bushman, Rothstein, & Anderson, 2010;Ferguson & Kilburn, 2010), the most recent meta-analyses show that exposure to video game violence can have detrimental short-and long-term effects on aggressive and prosocial behavior (Anderson et al., 2010;Greitemeyer & Mügge, 2014).",1 | |
| "Institutions also frame whether a situation is cooperative or competitive, which determines which preferences and norms people apply.",1 | |

| Our observation that angry subjects contribute less could be the result of a change in social preferences or a change in beliefs about the behaviour of others.,1 | |
| "They showed that a sanctioning system could undermine interpersonal trust, which can result in decreased cooperation in a similar social dilemma situation without a sanctioning system.",1 | |
| "As far back as the Upper Palaeolithic, we see evidence of large settlements behind defensive walls (Johnson & Earle 2000).",0 | |
| "The effect of actions by prior participants on the behaviors of subsequent participants was examined primarily in voluntary contribution experiments that examined how an initial voluntary contribution by a group leader led to contributions by others (Güth, Levati, Sutter, & van der Heijden, 2007) and experiments that examined how contributions by players informed about the value of a public good can positively influence contributions by uninformed players when such contributions are sequential (Potters, Sefton, & Vesterlund, 2005).",1 | |
| "Sure, I'd receive $9, but the fact that he received no money because of my selfish action I believe significantly outweighs the monetary value of $9.",1 | |
| Our results suggest that the competition scheme is attractive enough to gather sufficient support in a majority vote but not if individual groups are given a veto.,1 | |
| Mis-coordination tends to arise in networks where two players are symmetrically situated.,1 | |

| "They understood that rendering people interdependent, in the marketplace and elsewhere, increases the stakes they have in others' outcomes and thereby fosters the development of other-regarding motives.",1 | |
| "It may be that for fcmalc S's the Prisoner's Dilemma game is less interesting or important than for male Ss and consequently their cooperative and competitive acts conveyed very little meaning with regard to interpersonal feelings, Another possibility is that in behavior communicated to another person, females reveal less about their feelings toward that person and their own feelings are, in turn, less affected by the actions of that person as compared to malts.",1 | |
| "Though not as high as the theory predicts, proposer power is increased with the presence of a vote of confidence procedure, and proposers take advantage of that power.",1 | |
| This indicates that the behavior of each individual group could be accounted for reasonably by the main effects of prior experience and reward.,1 | |
| Cooperation thus tends only to occur if people are under the impression that they can trust one another.,1 | |
| "At least 2 factors may influence the emergence of cooperative behavior in this well-known collective action problem: the incentive structure of the game itself, and the intrinsic social preferences of each of the players.",1 | |
| "As predicted, there is a highly significant interaction between time pressure and experience (column 2, coefficient ¼ 0.350, P ¼ 0.008).",0 | |
| "The shift toward strategies of conditional cooperation in the framed games may indicate that people understood the framed game as a context where extrinsic motivations apply and the standard game as a context where intrinsic motivations apply, as Baumard implies.",1 | |
| "In the left panel, the payoff for player i is a function of his or her individual level of extraction under two scenarios.",0 | |
| "However, by cooperating, P also ensures that the gain to OP is 2 units (regardless of OP's choice): If P cooperates and OP cooperates, OP earns 3 units (rather than 1, if P had defected); if P cooperates and OP defects OP earns 4 units (rather than 2, if P had defected).",0 | |
| Our own speculation is that a kind of culturally imposed norm leads people who are strangers to each other to act guardedly.,1 | |
| "In natural settings, punishment occurs in various forms, for example, formal versus informal, public versus private, material versus symbolic.",0 | |
| "Figure 1 and Table 1 show that when the first mover keeps more than $7, directness is punished more harshly: Average punishment is greater when the first mover extracts rents directly, and many subjects punish in this direction.",1 | |
| "A total of 144 subjects, 72 of each sex, was assigned to promise credibility conditions of 10%, 50%, and 90%; reward levels of $5, $10, and $20; and simulated strategies which were either 50% or 90% cooperative over the 100 trials.",0 | |

| "Perhaps because residents of the USA have a narrower, more localized view, they tend to contribute a much higher proportion to their local public good.",1 | |
| "The logic behind this is natural: It is cheaper to spur on members to make additional contributions when their impact on the group account return increases, since every single contribution will give rise to more positive externalities to all group members.",1 | |
| "More data, and possibly greater variation in the contributions of others, can be obtained by pooling decisions from repeated play.",1 | |
| Subjects might have inferred from the capable-but-failing partner's behavior that he or she disvalued the task or the performance incentive.,1 | |
| "One of the variations that may be well learned is that when groups are involved, competitiveness, or a max rel orientation is valued.",1 | |
| "Swingle and Gillis's finding can be explained by the optimality argument of Downing et al. (1968): if ""the other"" is consistently competitive, rational pursuit of own gain dictates reciprocated competition in the prisoner's dilemma game, which was used.",1 | |
| "We assigned players to groups of either 3, 4, or 5 people and remained fixed during the whole session.",0 | |
| Gürerk et al. (2010) hypothesize that punishment may not explain a cooperative equilibrium if players are inequity averse and the setting is such that the current ability to contribute to the public good is a fraction of total earnings from the game.,1 | |
| "Second, the present study only weakly corroborated a previous characterization of the effects of ingroup cohesion upon intergroup biases.",0 | |
| "Mediation analyses revealed a pattern of results that is consistent with the possibility that the role of social support was mediated by max rel, or participants' concern for maximizing the relative outcomes of their group.",1 | |
| The addition of this variable makes a significant contribution to the explanatory power of the decision-making model.,1 | |
| "In the standard condition, such a $5 loss occurs if an individual's contribution would be either deficient or redundant.",0 | |
| "While value domains are generally fuzzy concepts (Schwartz, 1994, p. 25), the values included in our Prosocial domain were largely consistent with Feather's (1991) Universal prosocial domain (equality, a world of beauty, a world at peace, inner harmony and freedom).",0 | |

| The upper boxes both contained red doors; the lower boxes both contained green doors.,0 | |
| "Given the limited number of punishment instances after the first punishment stage, and because our main interest is to explore how the possibility of a feud affects altruistic punishment, we will henceforth focus our analysis of punishment on first-stage punishment.",1 | |
| "Equally, if a designated noncontributor were, for some reason, to go ahead and contribute, the contribution of each member of the designated set would not be critical, and there would be the opportunity for at least one designated contributor to free ride.",1 | |
| Thus individual uncertainty was reduced leading to a better transition process with more stable institutions.,1 | |
| The authors proved evidence of the superior performance of seed contributions for the reason that the challenge treatment outperformed both control conditions.,1 | |
| "The TPBG is sufficiently simple that most sessions were completed within two hours, even with chat, and play largely stabilized by the end of Round 20.",0 | |
| "The same brain functions appear to be involved in different cooperative settings, but to a much lesser extent when they involve synergy.",1 | |
| "Bliss and Nalebuff (1984) show conditions under which the probability of the public good provision converges towards unity with an increase in group size, and they prove there exists an equilibrium in which the lowestcost agent eventually provides the public good.",1 | |
| "Since priming was conducted at the supraliminal and subliminal level, it is possible that the situational cues may not be mediated by impressions of the partner but rather have a direct effect on cooperative behaviour (Bargh et al., 1996;Smeesters et al., 2003).",1 | |
| This suggests that punishment also triggers feelings of guilt and shame that induce individuals to behave pro-socially (Barr 2001;Fessler & Haley 2003).,1 | |
| "Given the opportunity to discuss the problem and coordinate strategies for 10 min before making their decisions privately, the subjects organized themselves by specifying the m contributors in a way that always resulted in an efficient provision of the public good.",1 | |

| The fact that subjects who display a larger context-dependent change in connectivity between right DLPFC and pfffff reject unfair offers more frequently also suggests the possibility of a deeper understanding of individual differences in normative behavior in terms of connectivity differences between these brain regions.,1 | |
| "Games with the exact same objective structures produce different behaviour depending on the framing (Hoffman et al., 1996(Hoffman et al., , 1999)).",1 | |
| Higher coefficient for the current game in the second half would indicate that the subjects were learning to conditionalise more on the game (which imply less contrast effect of the previous game).,1 | |
| "Therefore, such knowledge may represent a strong motivation for potential members of a club to exert sufficient effort to reach a provision target.",1 | |
| "This idea has received criticism, however, by those who suggest that the speeded responses to fearful or threatening stimuli are due to the relevance of the stimuli to the individual rather than its negative valence (Sander et al., 2003;Brosch et al., 2007Brosch et al., , 2008Brosch et al., , 2010)).",1 | |
| Efficiency levels fall because the maximum earnings possible increase with carryover (due to higher endowments or MPCR levels in stage 2).,1 | |
| Participants were told a cover story that they were part of a large ongoing study in which they would be playing the role of proposer and they would make the decision about how to divide the money for 20 different receivers.,0 | |
| "Historically, women have taken on peacekeeping roles in groups (De Groot & Peniston-Bird, 2000;Goldstein, 2003), perhaps because they are more concerned with preserving group harmony (Baumeister & Sommer, 1997;Geary, 1998).",1 | |
| "However, the effect is moderately large (the probability of voting in favour of competition is 18.9 percentage points lower for risk-averse subjects) and the lack of statistical significance may be ascribed to the small number of subjects classified as risk averse.",1 | |
| "The increase-only mechanism helps prevent players from being free ridden, providing them with a kind of assurance.",1 | |
| "In Appendix A, we present an alternate model that accounts for in-group preferences and can explain some of the behavior we observe.",0 | |

| "Given that tit for tat yielded greater outcomes than cooperative or noncooperative partners, and given that tit for tat has received considerable attention as a functional strategy, it is interesting to note that in social dilemmas in which locomotion is possible, tit for tat can do even better if this strategy is accompanied by locomotions to high interdependence rather than low interdependence.",1 | |
| "When a leader can allocate the benefits, the leader can incentivize workers by allocating benefits to those who contribute the most and withholding them from those who free-ride.",1 | |

| "Given the minimal costs associated with using passive, self-sacrificing cooperation in the iterated PD game, it is fair to suggest that older adults were more effective than young adults at managing conflict with the Selfish Stranger.",1 | |
| "As a larger degree naturally results in a larger transitivity, we calculate the expected value of transitivity given a certain network degree and a certain size in a random graph in simulations (10,000 iterations), and report the deviation of the observed transitivity from the expected transitivity (that is, observed transitivity minus expected transitivity).",0 | |

| The belief version goes on to suggest that there may be certain assumptions built-in to our cognitive processing of social dilemmas that leads members of our species to systematically misunderstand (or disbelieve) some aspect of the experimental game.,1 | |
| "Complementing this preliminary evidence, the dissertation presents several studies that support the reverse appraisal proposal; in particular, the dissertation presents evidence that, when engaged in a social dilemma, people are capable of inferring, from emotion displays, how the counterpart is appraising the ongoing interaction and, from this information, further infer what the counterpart's intentions are.",1 | |

| "In particular, Results 1 and 3 suggest that, depending on the research question, the researcher may face a tradeoff: high incentives for exact beliefs increase belief accuracy but strongly incentivized beliefs may also bias contributions away from levels that would be observed were beliefs not elicited at all or only hypothetically.",1 | |
| Our experiments provide direct tests between the rapport explanation and rival explanations.,0 | |

| This time the initial network was a small-world network with an average nodal clustering of .71.,0 | |
| Hump-shaped contributors have the same conditional contribution pattern as conditional cooperator up to some maximum point and then negative correlation based on the same criterion as for conditionally cooperating behavior.,0 | |
| "Much has been written about the impact of climate change on resource conflicts (Ember and Ember 1992, Mwiturubani 2010, Downing et al. 2014;Harari and La Ferrara 2014, unpublished manuscript).",0 | |
| "The pattern of results in Fig. 1D is very similar to the one reported by Nalbantian & Schotter (1997), who found that with equilibrium contribution close to the upper bound of the strategy space mean contribution levels were stable over trials but somewhat below the equilibrium level.",0 | |
| "We find at least some evidence that giving in the trust, public good and dictator games, and reciprocity in the trust and ultimatum games vary over the menstrual cycle.",0 | |
| "The Pareto-optimal request and contribution level, shown in the left panel of Table 1, are the same across the three treatments.",0 | |
| Our exploratory analyses revealed regional overlaps in the genotype-by-CAS interaction contrasts.,0 | |
| In the conclusion we discuss why we find evidence for discovered rather than constructed preferences.,0 | |
| We decomposed the interaction by comparing patterns of implicit racial bias between ineffective and effective external incentive conditions.,0 | |
| The integer payoff values are understood so that 4 (or 1) is the most (or least) preferred outcome.,0 | |
| "Within the fine and no-fine conditions for both the pregame and postgame data, the distribution of choices from males was compared to that of females using the chi square test.",0 | |
| "In six different trials, we found two reciprocal pairs per trial significantly more often than would be expected by chance.",0 | |
| "Given the fact that public services or goods are quite difficult to maintain, understanding how and when sanctioning systems may work in an effective manner to promote contributions to those public goods is an important task for social dilemma researchers.",0 | |
| "Among this latter group, we jointly estimate a warm-glow model with logit decision error, and find warmglow and noise parameter values which are comparable between the treatments.",0 | |

| "While the research reported here suggests that sympathy is important for social order, several questions remain.",0 | |
| We expected group cohesiveness to mediate the relationship between forgiveness and cooperation differently depending on transgressor response.,0 | |
| To test this we conducted three studies.,0 | |
| "In other words, expectations of the partner's behavior in one game were found to correlate with a player's choice in another game.",0 | |
| This effect would be due primarily to the significantly lower amount of cooperation for subjects assigned to the low potential reward position.,0 | |
