“…We observed several ERP components and the comparison between the two experimental conditions confirmed a positive-negative component waveform in the 150 − 400 ms time-range [113]. This waveform was more visible when participants made an offer (the proposer condition) and included a positive wave at a latency of about 200 ms, 'P200', and a negative deflection, at about 250-300 ms, the 'FRN'.…”

“…In addition, we investigated the role of individual differences, in particular the personality characteristics of honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience [2] as factors potentially affecting the willingness-to-share. We also explore the neurobiological correlates of the decision-making process, extending our previous study [113]. In particular, we present here the ERPs associated with sub-processes of emotional salience detection (P200), combining incoming information into an emerging emotional representation (FRN), as well as decision-making stages (as indicated by behavioural results) in all participants.…”

“…The second component is a negative wave peaking at about 350 ms, identified as Feedback-Related Negativity, 'FRN'. Figures 5.6A and 5.6B show these waveforms in response to decision-making eliciting stimuli without [87,113] and with emotional priming (studied here), respectively, along the midline at electrode positions Fz, FCz, Cz, CPz. The amplitude of both waves are larger towards the frontal areas.…”

Human decision-making has consistently demonstrated deviation from "pure" rationality. Emotions are a primary driver of human actions and the current study investigates how perceived emotions and personality traits may affect decision-making during the Ultimatum Game (UG). We manipulated emotions by showing images with emotional connotation while participants decided how to split money with a second player. Event-related potentials (ERPs) from scalp electrodes were recorded during the whole decision-making process. We observed significant differences in the activity of central and frontal areas when participants offered money with respect to when they accepted or rejected an offer. We found that participants were more likely to offer a higher amount of money when making their decision in association with negative emotions. Furthermore, participants were more likely to accept offers when making their decision in association with positive emotions. Honest, conscientious, and introverted participants were more likely to accept offers. Our results suggest that factors others than a rational strategy may predict economic decision-making in the UG. 5.1 Behavioural Economics of Ultimatum Game and Emotion Traditional economic models emphasise the importance of rational choices [115]. In this framework humans could be replaced by "rational agents", being purely

“…Contactless monetary transactions are rapidly increasing in all socio-cultural environments and in the absence of effective face-to-face negotiations it seems crucial to gain a better understanding of decision-making processes. The observation that individuals characterized by well-defined impairments in decision making, as they tend to take decisions not advantageous for their personal lives and for their social status, may also be characterized by biophysical measurements associated with brain activity led to define the Somatic Markers Hypothesis (Bechara et al, 1994; Bechara and Damasio, 2005; Rilling and Sanfey, 2011; Villa et al, 2012). The observation of such somatic markers is important to investigate the neural basis of decision making processes.…”

In the framework of neuroeconomics, Event Related Potentials (ERPs) were recorded during a combination of a Dictator Game (DG), in which the participants always played the role of Allocators, and an Ultimatum Game (UG), in which the participants always played the role of Responders. Behavioral analysis showed that the majority of participants were characterized by very low levels of altruistic decision making, which included two homogenous groups of individuals, one expressing fairness (GrpF, about 26%) and one selfish behavior (GrpS, about 20%). In the analysis of both games, an early negativity (N1) in the fronto-central cortical sites distinguished the GrpF and GrpS participants. The subsequent P2 wave component appeared more associated with the characteristics of the stimulus than with its behavioral value. During UG, we observed that a medial frontal negativity (MFN) occurred earlier and with greater amplitude in GrpS than in GrpF, which depended to a large extent to a spiteful punishment when the Responder refused offers less favorable for himself. The late positive component (LPC) of ERP recorded in posterior-parietal cortical sites was evoked earlier and with greater amplitude during UG than in DG and, in both games, LPC was evoked earlier and with greater amplitude in GrpS than in GrpF. Our results bring new evidence to the existence of different circuits activated by the evaluation of fair and unfair proposals in participants characterized by different expressions of perceived fairness, thus suggesting that particular brain dynamics could be associated with moral decisions.
