A scientific explanation to why people perform better after receiving a compliment

A team of Japanese scientists have found scientific proof that people doing exercises appear to perform better when another person compliments them. The research was carried out by a group lead by National Institute for Physiological Sciences Professor Norihiro Sadato, Graduate University for Advanced Studies graduate student Sho Sugawara, Nagoya Institute of Technology Tenure-Track Associate Professor Satoshi Tanaka, and in collaboration with Research Center for Advanced Science and Technology Associate Professor Katsumi Watanabe. The team had previously discovered that the same area of the brain, the striatum, is activated when a person is rewarded a compliment or cash. Their latest research could suggest that when the striatum is activated, it seems to encourage the person to perform better during exercises. The paper is published online in PLOS ONE

According to Professor Sadato, “To the brain, receiving a compliment is as much a social reward as being rewarded money. We’ve been able to find scientific proof that a person performs better when they receive a social reward after completing an exercise.  There seems to be scientific validity behind the message ‘praise to encourage improvement’. Complimenting someone could become an easy and effective strategy to use in the classroom and during rehabilitation.”
