Behavioural and functional magnetic resonance imaging studies: Decision making on belief and feeling while reading tweet texts 2019

This data set contains two experimental studies, the studies investigated how perceived information sources would affect readers' decision making about belief and feeling while they read tweet texts. In the behavioural study, we aimed to validate stimuli that were then used in the fMRI experiment. We examined our hypothesis that tweet texts accompanied by more often used information sources of individuals (i.e. the logos of media) would significantly increase the degrees of their belief about the texts, compared with tweet texts accompanied by the information sources that they never used. In the fMRI study, we hypothesised that perceived information sources would modulate one's decision-making on belief and feeling about tweets, and that the process would involve social emotional brain regions.
