Monetary Effects on Fear Conditioning
2013
Summary.——Previous research has found that the loss of money as a negative secondary reinforcer was as effective as a primary reinforcer during fear conditioning. The purpose of the present study was to explore the effect of monetary gain as a positive secondary reinforcer in fear conditioning. Participants were assigned to a high-reward group or low-reward group. Three kinds of squares prompting non-compensation shock, compensation shock, and no shock were presented. Skin conductance responses (SCRs) and self-ratings were recorded. The results revealed that (a) both SCRs and self-ratings in the compensation shock condition were lower than in the non-compensation shock condition, suggesting that money might block the learning stage of fear conditioning; and (b) a higher ratio of fear reduction was present in self-rating when compared to SCRs, suggesting that people might overstate the utility of money, subjectively. Monetary effects, the effects of different amounts of money, and the differences between s...
