Abstract

Climate change has become a relevant matter in today's society. As the condition of the earth is declining, it is important to understand what processes govern environmentally relevant be-haviors. We chose to investigate behavioral and neuroimaging differences based on individuals' psychological core values. Our experiment used a modified version of the monetary incentive task while acquiring functional MRI data. Participants played a game for which they were able to gain money for themselves or the environment (i.e. three pro-environmental organizations). Participants with opposing values were grouped in order to create a group with a high self-interest (i.e. egoistic group) and a group which exhibit concerns for the protection of the envi-ronment and nature (i.e. biospheric group), and compare them. Although the groups did not differ in terms of behavioral responses, our manipulation exhibits an increased activity in a reward-related brain region (i.e. the left putamen) for the egoistic group when there was a po-tential financial gain for themselves. This could suggest the egoistic group perceived the finan-cial gain as more "rewarding" than their biospheric peers but we cannot ignore this activation could be related to motor activity. However, our groups were behaving rather similarly from the behavioral results and the response to the potential monetary gain for the self or the envi-ronment was comparable. Results could suggest that the "self" and the "environment" were perceived as similar in our sample. These results may be a manifestation of today's heightened concern for the environment and the awareness of climate change's existence.
