TI  - How choice modifies preference: neural correlates of choice justification.

AB  - When making a difficult choice, people often justify the choice by increasing 
      their liking for the chosen object and decreasing their liking for the rejected 
      object. To uncover the neural signatures of choice justification, we used 
      functional magnetic resonance imaging to monitor neural activity when subjects 
      rated their preference for chosen and rejected musical CDs before and after they 
      made their choices. We observed that the trial-by-trial attitude change (i.e., 
      increase of preference for chosen items and decrease of preference for rejected 
      items) was predicted by post-choice activity in the ventral medial prefrontal 
      cortex (MPFC), right temporal-parietal junction, anterior insula, and bilateral 
      cerebellum. Furthermore, individual difference in choice justification (i.e., 
      increased preference for chosen items minus decreased preference for rejected 
      items) was predicted by post-choice neural activity in the dorsal MPFC, left 
      lateral prefrontal cortex, and right precentral cortex positively. In addition, 
      interdependent self-construal was correlated with decreased activity in the 
      ventral MPFC in the post-choice than pre-choice sessions. These findings suggest 
      that both negative arousal/regulation and self-reflection are associated with 
      choice justification. This provides evidence for the self-threat theory of choice 
      justification.
