Altered neural responses to social fairness in bipolar disorder
2020
Highlights • Bipolar disorder is characterized by impaired processing of social fairness. • BD patients exhibit increased rejection of moderate unfairness in Ultimatum Game. • BD patients display decreased response to moderate unfairness in anterior insula. • BD patients deactivate posterior and middle insula in response to unfairness. • Trait impulsivity positively correlated with deactivations in posterior insula.
Need for Conclusive Evidence that Positive and Negative Reciprocity are Unrelated
2013
The strong reciprocity model of the evolution of human cooperation (1) postulates that positive and negative reciprocity are associated. Recently in PNAS, Yamagishi et al. (2) reported results that challenged this proposition by showing that the tendency to reject unfair offers in the ultimatum game is not related to various indicators of positive reciprocity in other experimental games. This result was corroborated by a nonsignificant correlation between self-reported positive and negative reciprocity.
Collaborative roles of Temporoparietal Junction and Dorsolateral Prefrontal Cortex in Different Types of Behavioural Flexibility
2017
AbstractBehavioural flexibility is essential for everyday life. This involves shifting attention between different perspectives. Previous studies suggest that flexibility is mainly subserved by the dorsolateral prefrontal cortex (DLPFC). However, although rarely emphasized, the temporoparietal junction (TPJ) is frequently recruited during flexible behaviour. A crucial question is whether TPJ plays a role in different types of flexibility, compared to its limited role in perceptual flexibility. We hypothesized that TPJ activity during diverse flexibility tasks plays a common role in stimulus-driven attention-shifting, thereby contributing to different types of flexibility, and thus the colla…
Influence of expressive versus mechanical musical performance on short-term memory for musical excerpts
2012
Recognition memory for details of musical phrases (discrimination between targets and similar lures) improves for up to 15 s following the presentation of a target, during continuous listening to the ongoing piece. This is attributable to binding of stimulus features during that time interval. The ongoing-listening paradigm is an ecologically valid approach for investigating short-term memory, but previous studies made use of relatively mechanical MIDI-produced stimuli. The present study assessed whether expressive performances would modulate the previously reported finding. Given that expressive performances introduced slight differences between initially presented targets and their target…
Participation Costs for Responders Can Reduce Rejection Rates in Ultimatum Bargaining
2008
This paper reports data from an ultimatum mini-game in which responders first had to choose whether or not to participate. Participation was costly, but the participation cost was smaller than the minimum payoff that a responder could guarantee himself in the ultimatum game. Compared to a standard treatment, we find that the rejection rate of unfavorable offers is significantly reduced when participation is costly. A possible explanation based on cognitive dissonance is offered.
Gender differences in ultimatum games: Despite rather than due to risk attitudes
2012
Abstract We analyze experimental data obtained from an ultimatum game framed as a situation of employee–employer negotiation over salaries. Parallel to this, we elicit subjects’ risk attitudes. In the existing literature, it has often been conjectured that gender differences in strategic environments are partly due to differences in risky decision making. Our evidence suggests that both gender and risk-related effects co-exist in ultimatum bargaining. However, differences in risk attitudes cannot explain gender effects in ultimatum bargaining.
The hidden side of the Ultimatum Game: The role of motivations and mind-reading in a two-level one-shot Ultimatum Game
2015
The main aim of our study is to investigate the role of motivations and mind-reading in a two-level one-shot Ultimatum Game with three players. Our intention is to analyse subjects’ behaviour in both the responder and proposer roles. In the responder role, we found that the difference between the subjects’ expectations and the actual offers was the major factor that influenced their decisions and motivations in receiving money. In the proposer role, our results showed a significant influence of mind-reading, with a positive association between the fairness of subjects’ offers and the subjects’ expectations about the recipients’ willingness to accept. Although a shared concept of fairness ex…
Fairness behavior in an economic crisis environment: a Romanian experimental perspective
2012
Abstract In the context of the current prolonged economic crisis, we were wondering if the typical behaviour of Romanians in terms of their ‘fairness’ has suffered any modification. This study is trying to identify the effect of psychological pressure created by the economic crisis on fairness using the Ultimatum Game. We aim to look at the question if this hypothetical phenomenon applies mostly to people who use economic information in their day-to-day life (e.g., economic science students) or if it also affects different populations (e.g., psychology students). Another aim is to understand if any difference is influenced mainly by vocational personalities as Holland hs described.
The whip and the Bible : punishment versus internalization
2021
First published online: 27 August 2021 A variety of experimental and empirical research indicate that prosocial behavior is important for economic success. There are two sources of prosocial behavior: incentives and preferences. The latter, the willingness of individuals to “do their bit” for the group, we refer to as internalization, because we view it as something that a group can influence by appropriate investment. This implies that there is a trade-off between using incentives and internalization to encourage prosocial behavior. By examining this trade-off we shed light on the connection between social norms observed inside the laboratory and those observed outside in the field. For ex…
