There was a programme on BBC Radio 4 this morning discussing sympathy; part of the Emotional Rollercoaster series.
I didn't hear the whole programme, but just a snippet on empathy, and research showing that people with lower emotional arousal around upset people were more likely to help them. Emotional Intelligence in action!
At radio 4's Emotional Rollercoaster webpage you can listen to the programme and test your sensitivity to disgust!
Next week's programme is on love.
