Strength: there's evidence to support an important role for mirror neurons in human social cognition.Haker et al (2012) demonstrated that an area of the brain believed to be rich in motor neurons, is involved in contagious yawning, which is widely seen as a simple human empathy, the ability to perceive mental states in others. A brain scanning technique (fMRIs) was used to asses brain activity in participants whilst they were stimulated to yawn by showing them a film of others yawning. When they yawned, in response, participants showed considerable in Brodmann's area, an area believed to be rich in mirror neurons. This study supports the importance of mirror neurons in social cognition because they show that regions of the brain believed to be rich in motor neurons activate when empathy or perspective-taking occurs.
