An fMRI Dataset on Social Reward Processing and Decision Making in Younger and Older Adults by David V. Smith, Rita M. Ludwig, Jeffrey B. Dennison, Crystal Reeck, Dominic S. Fareri

“…As part of a pilot study, we collected behavioural and functional magnetic resonance imaging (fMRI) data from 50 participants (Younger: N = 26, ages 18–34 years; Older: N = 24, ages 63–80 years) who completed three tasks in the scanner: an economic trust game as the investor with three partners (computer, stranger, friend) as the investee; a card-guessing task with monetary gains and losses shared with three partners (computer, stranger, friend); and an ultimatum game as responder to three anonymous proposers (computer, age-similar adults, age-dissimilar adults). …”

Neural basis of increased costly norm enforcement under adversity by Wu, Y, Yu, H, Shen, B, Yu, R, Zhou, Z, Zhang, G, Jiang, Y, Zhou, X

“…Using fMRI and a variant of the ultimatum game and functional magnetic resonance imaging, we investigated how the brain differentially responds to fairness in loss and gain domains. …”

Not on my team: Medial prefrontal cortex responses to ingroup fusion and unfair monetary divisions by Apps, M, Mckay, R, Azevedo, R, Whitehouse, H, Tsakris, M

“…Here, subjects performed rounds of the Ultimatum Game, being offered fair or unfair divisions of money from supporters of the same soccer team (ingroup), the fiercest rival (outgroup) or neutral individuals. …”

Individualistic attitudes in Iterated Prisoner’s Dilemma undermine evolutionary fitness and may drive cooperative human players to extinction by Pulcu, E

“…Following the footsteps of Press and Dyson (2012), I implemented their evolutionary game-theoretic modelling from Iterated Prisoner’s Dilemma (a behavioural economic probe of interpersonal cooperation) and re-analysed already published data on human proposer behaviour in the Ultimatum Game (a behavioural economic probe of altruistic punishment) involving 50 human participants versus stochastic computerized opponents with prosocial and individualistic social value orientations. …”

How do children adapt their fairness norm? Evidence from computational modeling. by Frédérick Morasse, Miriam H Beauchamp, Élise Désilets, Sébastien Hétu

“…Thirty children (7-11 years, M = 7.9 SD = 0.85, 11 girls) played the role of Responder in a modified version of the Ultimatum Game-a two-player game based on the fairness norm-in which they had to choose to accept or reject offers from different Proposers. …”

Implicit and Explicit Preferences for Golden Ratio by Claudia Salera, Camilla Vallebella, Marco Iosa, Anna Pecchinenda

“…Then, we assessed their explicit preferences by asking them to rate the stimuli in terms of pleasantness and by completing a line bisection task and the Ultimatum Game. The results revealed the typical effects observed in implicit association tasks, with improved response times and accuracy when golden ratio stimuli were associated with positive word categories. …”

Electrophysiological, emotional and behavioural responses of female targets of sexual objectification by Bianca Monachesi, Alice Deruti, Alessandro Grecucci, Jeroen Vaes

“…In the present study, we investigated women’s emotional and electrophysiological responses during simulated computer-based objectifying social interactions, and we examined consequent punishing behaviours towards the perpetrator using the ultimatum game. Behavioural results (N = 36) showed that during objectifying encounters women generally felt angrier/disgusted and tended to punish the perpetrator in later interactions. …”

Social preferences trump emotions in human responses to unfair offers by Vincent Buskens, Ingrid Kovacic, Elwin Rutterkamp, Arnout van de Rijt, David Terburg

“…We systematically varied whether rejections led proposers to lose their share (Ultimatum Game; UG) or not (Impunity Game; IG). Results favor preference-based accounts: Impunity minimizes rejection despite increasing subjectively reported anger. …”

Dynamic modulation of inequality aversion in human interpersonal negotiations by Murphy, DAJ, Xie, J, Harmer, CJ, Browning, M, Pulcu, E

“…Here, we report results from an iterative Ultimatum Game (UG), in which the proposer’s facial emotions and offer amounts were sampled probabilistically based on the participant’s decisions. …”

How Cortisol Reactivity Influences Prosocial Decision-Making: The Moderating Role of Sex and Empathic Concern by Qionghan Zhang, Qionghan Zhang, Jianhong Ma, Urs M. Nater

“…Subsequently, participants completed three economic tasks—the dictator game, the ultimatum game, and the third-party compensation game. …”

Serotonin selectively influences moral judgment and behavior through effects on harm aversion. by Crockett, M, Clark, L, Hauser, MD, Robbins, T

“…This harm-avoidant bias after citalopram was also evident in behavior during the ultimatum game, in which subjects decide to accept or reject fair or unfair monetary offers from another player. …”

Testosterone is associated with cooperation during intergroup competition by enhancing parochial altruism by Luise eReimers, Esther Kristina Diekhof

“…First evidence for a link between testosterone and parochial altruism comes from recently reported data of male soccer fans playing the ultimatum game. In this study high levels of endogenous testosterone predicted increased altruistic punishment during outgroup interactions and at the same time heightened ingroup generosity. …”

Introducing a Fair Tax Method to Harden Industrial Blockchain Applications against Network Attacks: A Game Theory Approach by Fatemeh Stodt, Christoph Reich

“…The mechanism, inspired by the ultimatum game, progressively punishes malicious actors to increase the cost of fraud, improve the compensation system, and utilise the reward reporting capabilities of blockchain technology to further discourage fraudulent activities. …”

Data-driven evolutionary game models for the spread of fairness and cooperation in heterogeneous networks by Jing-Yi Li, Jing-Yi Li, Jing-Yi Li, Wen-Hao Wu, Ze-Zheng Li, Wen-Xu Wang, Wen-Xu Wang, Boyu Zhang

“…Here, based on the experimental phenomena and data, we show a joint effect of social preference and network heterogeneity on promoting prosocial behaviors by building evolutionary game models. In the network ultimatum game and the prisoner’s dilemma game with punishment, inequality aversion can lead to the spread of costly punishment for selfish and unfair behaviors. …”

Decoding social decisions from movement kinematics by Giacomo Turri, Andrea Cavallo, Luca Romeo, Massimiliano Pontil, Alan Sanfey, Stefano Panzeri, Cristina Becchio

“…We addressed this question by developing a motor version of a widely used behavioral economic game - the Ultimatum Game - and using a multivariate kinematic decoding approach to map parameters of social decisions to the single-trial kinematics of individual responders. …”

Incentives, reputation and learning by Davies, E
