Overlapping activation for the self- and partner-reputation conditions.

Significant activation related to the interaction effects of target×reputation in the medial prefrontal cortex (mPFC) is shown. Red and green indicate self-specific (self (reputation – no-reputation)>stranger (reputation – no-reputation)) and partner-specific (partner (reputation – no-reputation)>stranger (reputation – no-reputation)) interaction effects, respectively. Overlapping activation between these two interaction effects is also shown (yellow).
