Originally, the feedback related negativity (FRN) event-related potential (ERP) component was considered to be a robust neural correlate of non-reward/punishment processing, with greater negative deflections observed following unfavourable outcomes. More recently, it has been suggested that this component is better conceptualised as a positive deflection following rewarding outcomes. The current study sought to elucidate the nature of the FRN, as well as another component associated with incentive-value processing, the P3b, through application of a spatiotemporal principal components analysis (PCA). Seventeen healthy controls played a computer electronic gaming machine (EGM) task and received feedback on credits won or lost on each …

A Test Of The Renewable Resources Model Of Multiple Gains And Multiple Losses, Sandra C. Jones

Eight choice scenarios were used to test Linville and Fischer's (1991) Renewable Resources Model, which predicts that people will prefer to separate multiple gains over time and also to separate multiple losses over time, the latter prediction being contrary to Kahneman and Tversky's (1979) Prospect Theory. The Renewable Resources Model was tested under conditions that, theoretically, should enhance the dual separation outcomes. However, in seven of the eight choice scenarios, complete reversals of these outcomes were observed B that is, the participants in the experiments preferred to combine multiple gains and to combine multiple losses. Explanations of these unexpected results …
