A
study shows that a part of the brain called the anterior cingulate cortex (ACC)
seems particularly attuned to other people’s good news, but how it responds
varies substantially depending on our levels of empathy. For people who rated
themselves as highly empathetic, the ACC responded only when another person had
good news coming, but for people who gave themselves lower empathy scores, the
ACC also responded when bad news was predicted for themselves. This new insight
could prove important in understanding the role of the ACC in disorders of
social behaviour and empathy, including psychopathy and autism. Further studies
could focus on how the brain responds to our own success compared to others’ in
people with these disorders. Researchers scanned the brains of 30 male
volunteers aged 19-32 using functional magnetic resonance imaging while they
saw symbols that predicted how likely either they or another person was to win
money. Participants also completed a questionnaire that assessed their empathy
level in the week before they had the scan. The study found that the ACC region
of the brain activated in all the volunteers when someone else was very likely
to win money. However, there were substantial differences in how ‘specialised’
this ACC response was, which were linked to how empathetic participants said
they were. Participants whose ACC activation was the most specialised for other
people showed an ACC response only when the other person was very likely to win
money. These volunteers had rated themselves as high in empathy. However,
participants whose ACC activation was less specialised for other people also
showed an ACC response when they themselves were very unlikely to win money.
These participants had given themselves much lower empathy scores. Further
research is also needed to examine how real life social interactions can be
influenced by how specialised this area of the brain is, and whether these
results can help to explain why some people only feel happy for others’ success
when they feel successful themselves.
