A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations.

Understanding the way in which social behaviours such as altruism – when animals benefit others at their own expense – develop is a long-standing problem that has generated thousands of articles and heated debates.

Dr Florence Débarre of Biosciences at the University of Exeter led a study, published in Nature Communications, which presents a comprehensive framework that applies to a large class of population structures and identifies the crucial elements which support the evolution of social behaviour.

The Bright Side of Death: Awareness of Mortality Can Result in Positive Behaviors, Say MU Researchers

COLUMBIA, Mo. — Contemplating death doesn’t necessarily lead to morose despondency, fear, aggression or other negative behaviors, as previous research has suggested. Following a review of dozens of studies, University of Missouri researchers found that thoughts of mortality can lead to decreased militaristic attitudes, better health decisions, increased altruism and helpfulness, and reduced divorce rates.

“According to terror management theory, people deal with their awareness of mortality by upholding cultural beliefs and seeking to become part of something larger and more enduring than themselves, such as nations or religions,” said Jamie Arndt, study co-author and professor of psychological sciences. “Depending on how that manifests itself, positive outcomes can be the result.” (more…)

A polite act shows respect. But a new study of a common etiquette—holding a door for someone—suggests that courtesy may have a more practical, though unconscious, shared motivation: to reduce the work for those involved. The research, by Joseph P. Santamaria and David A. Rosenbaum of Pennsylvania State University, is the first to combine two fields of study ordinarily considered unrelated: altruism and motor control. It is to be published in a forthcoming issue of Psychological Science, a journal of the Association for Psychological Science.

“The way etiquette has been viewed by Emily Post—that you’re being proper by following social codes—is undoubtedly part of it,” said psychology professor Rosenbaum. “Our insight is there is another contributor: the mental representation of other people’s physical effort. Substantial research in the field of motor control shows that people are good at estimating how much effort they and others expend,” Rosenbaum continued. “We realized that this concept could be extended to a shared-effort model of politeness.” (more…)
