A computer-based environment developed with the aim to shed light on the origins of altruism: this is the innovative approach used by a research group at SISSA in Trieste, in collaboration with the University of Udine. This new study — recently published in the journal Neuropsychologia — immersed participants in a virtual environment that reproduced a building on fire which they had to evacuate in a hurry, deciding whether to save their lives or interrupt their escape and help rescue an injured person. The results showed that altruistic individuals self-reported to have greater concern for others’ wellbeing and had larger right anterior insula (a brain area involved in processing social emotions) compared to non-altruists. These results shed light on the role of compassion in motivating helping behaviour and its brain correlates.

“Our prosocial and altruistic impulses play a very important role in sustaining complex societal structure,” explained Giorgia Silani, the principal investigator of this research conducted at SISSA and now a researcher housed in University of Vienna, “However, studying altruism and its neural basis in lab-based environment poses unique ethical challenges. Indeed, it is difficult, if not impossible, to reproduce harmful situations realistically and then studying participant’s helping behaviour, especially if such situations pose physical threat to the life of the participant….”

In order to overcome these difficulties, researchers created a contextually-rich virtual reality environment in which participants were completely immersed. Indrajeet Patil, a former PhD student at SISSA and lead author of the paper, and currently a postdoctoral researcher at Harvard University, explained the novelty of the task: “During the experiment, participants were placed in a building from which they had to escape because of a sudden fire. The computer-based environment was characterised by intense audio-visual cues that contributed to increasing the experimental realism of the situation on the one hand, and the feeling of anxiety and danger on the other. Besides, a bar indicated how much “life energy” was left in one’s avatar.” Toward the very end of the escape, when there was very little energy left, participants had to make a very difficult decision: whether to rescue an injured person trapped under a heavy cabinet risking their own lives, or run for the exit ignoring the individual’s cries for help.

As participants completed the task in the virtual environment, described by all as “very realistic,” they underwent an MRI scanning to help acquire information about brain structure. Investigating the participants’ cerebral structure, scientists were able to relate their behaviours with the anatomy of specific areas of the nervous system.


“The outcomes highlighted that dominant part of the general population settled on benevolent decision: 65% ceased to protect the harmed individual regardless of the danger to the (virtual) self. Also, survey information uncovered that people who helped the caught human scored higher on empathic concern. Hence, an individual’s readiness to help other people in need at a cost to the self is by all accounts driven by other-situated minding inspiration” Indrajeet Patil underscored the critical takeaway message from the review. As to the mind structure information, specialists found that the benevolent people had a bigger foremost insula contrasted with that of the individuals who gotten away without making a difference. “The insula is a range entirely associated with the preparing of our social feelings” Giorgia Silani highlighted. “In this exploration, we were along these lines ready to examine neurostructural relates of helping conduct. This work produces different intriguing theories that can be researched in future work.”

  1. Blueberry pie is something that I would like to eat on every-day basic. I’ve been having a blueberry moment and it’s not over yet. Blueberry Pancakes and Blueberry Jam, sure. Blueberry Syrup, Blueberry Ice Cream and Blueberry-Buttermilk, Blueberry Pie and many more.

    And yeah I have a quick word on the sugar – start with the lesser amount and taste. Now that blueberries are truly in season, you might not want completely full amount.
