Uncovering the interaction between empathetic pain and cognition.

Recent studies have demonstrated that empathizing with pain involves both cognitive and affective components of pain. How does empathetic pain impact cognition? To investigate this question, in the present study, participants performed a classic color-word Stroop task that followed a pain portraying or a corresponding control image. We found that observing pain experience in another had a basic slowing down effect on Reaction times (RTs) during neutral Stroop trials. Further, it affected cognition in a way that it decreased interference and increased facilitation. Moreover, our findings revealed that RTs during the incongruent and congruent trials were essentially unchanged by pain observing (empathy vs. control). The data are best accounted by a two-opposing effect model that empathetic pain impacts cognition through two different ways: it slows down performance in general, and facilitates performance during incongruent and congruent trials in particular. In this way, the present study also lends support to an idea that all components of empathy should be understood from an integrative approach.
