Although the role of emotion in socioeconomic decision making is increasingly recognised, the impact of specific emotional disorders, such as anxiety disorders, on these decisions has been surprisingly neglected. Twenty anxious patients and twenty matched controls completed a commonly used socioeconomic task (the Ultimatum Game), in which they had to accept or reject monetary offers from other players. Anxious patients accepted significantly more unfair offers than controls. We discuss the implications of these findings in light of recent models of anxiety, (...) in particular the importance of interpersonal factors and assertiveness in an integrated model of decision making. Finally, we were able to show that pharmacological serotonin used to treat anxious symptomatology tended to normalise decision making, further confirming and extending the role of serotonin in co-operation, prosocial behaviour, and social decision making. These results show, for the first time, a different pattern of socioeconomic behaviour in anxiety disordered patients, in addition to the known memory, attentional and emotional biases that are part of this pathological condition.

Interest in the neural processes underlying decision making has led to a flurry of recent research in the fields of both moral psychology and neuroeconomics. In this paper, we first review some important findings from both disciplines, and then argue that the two fields can mutually benefit each other. A more explicit recognition of the role of values and norms will likely lead to more accurate models of decision making for neuroeconomists, whereas the tasks, insights into neural mechanisms, and mathematical (...) modeling common in neuroeconomic research offer moral psychologists the opportunity to expand their field and move beyond methodological limitations that may have hindered the field’s progress to this point. We conclude by highlighting an exciting group of recent studies that illustrate the potential of research that embraces the integrated moral/neuroeconomic approach that we suggest here. (shrink)

Psychological studies have long demonstrated effects of expectations on judgment, whereby the provision of information, either implicitly or explicitly, prior to an experience or decision can exert a substantial influence on the observed behavior. This study extended these expectation effects to the domain of interactive economic decision-making. Prior to playing a commonly-used bargaining task, the Ultimatum Game, participants were primed to expect offers that would be either relatively fair or unfair. A third group played the Game without receiving any prior (...) information about expected offers. As predicted, these expectations had a large effect on decisions made by participants in the Ultimatum Game, with those with expectations of fairness rejecting significantly more unfair offers than those participants who expected low offers. Implications for models of fairness and equity are discussed. (shrink)
