Daily brief research updates from the cognitive sciences
In times of crises and danger we may hide and flee as our natural instincts would guide us, or do something else: put ourselves at danger and help others.
Whenever there is a tragic event, there abound stories of individuals who have helped others, often at great risk to themselves. But why? I don’t mean that negatively, it is great, and I have helped others in critical situations myself, a number of times actually.
What I mean is that the brain would normally, we assume, prioritise ourselves and seek to save ourselves first rather than instinctively help others. But the opposite seems to happen.
We may assume this is empathy, or moral standards, but recent research just published has shown this doesn’t appear to be the case!
Joana Vieira and Andreas Olsson of the Karolinska Institute in Sweden have just published the intriguing results of a brain scanning study. They conducted a lab experiment in which 49 volunteers had their brains scanned while in a helping scenario.
Sorry, while in a brain scanner there is no running through fire to help others, ethical committees wouldn’t allow this anyway. But what they did do is give participants mild electrical shocks and they could avoid this and/or help others avoid this – virtually that is.
So far so good, but they manipulated the task by adding the risk of getting an even stronger electrical shock if they went to help the other person. This simulates scenarios in real life when helping others leads to greater danger for oneself. They also changed the proximity of threat by saying the electrical shock could be imminent.
So, what did they see?
Interestingly what the researchers saw is increased activation in certain regions in the brain while deciding to help others with threat to oneself. And no, they weren’t areas associated with moral, social behaviour, or cognitive behaviour. It was related to threat. Two regions: the amygdala which is strongly associated with threat detection, and an area called the insula which is involved in embodiment of feelings were both active and levels of activation correlated to willingness to help others.
What was also a surprise is that helping behaviours were correlated with this threat and defensive network but not with the distress of others. So, it is not the distress of others which was stimulating the helping but the perception of threat and the more intense this was the more likely and individual was to help.
This sounds counter-intuitive in some ways, we may assume staying calm would help, we know that too much threat can cause, stress, distress and shut down various other areas of the brain. So, I’d be Interested to know how these all play in to this.
Nevertheless, this does give us a fascinating insight into our brains when helping others. Viera and Olsson are planning further work researching how the presence of others influences behaviour on themselves and the other bystanders in similar helping scenarios. That also looks like fascinating research, and I will keep an eye out for the results.
I will also continue to help others – and hopefully my defensive network in my brain will remain active!
