In nearly every socially based interaction is trust ubiquitous. People do trust in situations, where standard theory predicts they should not. So why do they trust at all? But the quite more interesting question is how do they feel when faced with a betrayal? In order to try to answer this question, this paper provides an experimental approach to the processes in the brain during a betrayal. Therefore I used a Trust Game with a simple payoff structure, where on one the hand the incentives to trust were high enough and on the other the incentives to honour more than to defect were given.
With recent literature I hypothesized that the extension of a betrayal can be seen as difference between reward prediction and actual reward (so called reward prediction error). Consequently during the whole process there should be an involvement of prefrontal cortex – determine the theory of mind, the ventral striatum – involved in reward process, the amygdala – indicated fear response,..
These results may help to improve the understanding of the basis of social relationships thus negative consequences of a betrayal in private but also in interindividual/-institutional interactions can be reduced.
