Praise just as exciting as money, study finds

People get just as excited about receiving a compliment as they do at the prospect of getting money, according to the findings of a new Japanese study.

The study shows that the part of the brain called the striatum, the brain's reward-perception system, is activated when someone is paid a compliment.

The striatum is triggered in a similar way at the prospect of a financial reward.

The study's authors used functional magnetic resonance imaging (fMRI) to measure the brain activity of 19 study subjects.

The research team was led by Norihiro Sadato, a professor at the Japanese National Institute for Physiological Sciences, and Keise Izuma, a graduate student at the Graduate University for Advanced Studies in Okazaki, Japan.

Their findings were published in the journal Neuron.

In the summary of the Japanese study, the researchers noted: "Our findings support the idea of a 'common neural currency' for rewards and represent an important first step toward a neural explanation for complex human social behaviours."

The researchers explained in a summary accompanying their study that social behaviours like decision-making have long been studied by psychologists. However, scientists are now taking a greater interest in exploring the brain activity associated with these behaviours.

In fact, other research released this week used fMRI to measure brain activity. That study followed participants who were playing a computer game in which they had an assigned social rank.

The results showed that, for example, the part of the brain that is linked to action-planning was triggered in one player when a photo of another, superior player in the game flashed on the computer screen. As well, the part of the brain connected to frustration was stimulated when a player fared poorly against a player of lower rank.
