Screen+Shot+2017-10-04+at+6.40.36+PMSocial neuroscience is a discipline that studies neurobehavioral mechanisms in order to find out how the presence of others affects human behavior and mental processes. As the interface between social psychology and neuroscience, this area of knowledge was first introduced by John Cacioppo and Gary Brentson in 1992. Since social neuroscience encompasses a wide range of levels (from genes to social groups), studies in this field require the use of different approaches and specialists of different disciplines. This area of knowledge is sometimes referred to as “social brain”, the name of a complex network of the brain areas involved in many social cognitive activities. The scope of social science includes issues related to the human perception of various social factors and the resulting behaviors. For instance, this area of knowledge has been able to identify some of the cerebral mechanisms involved in the formation of social perceptions, trust, collaboration, empathy, theory of mind, isolation, ethics, prejudice, and stereotypes. Social neuroscience generally attempts to answer three categories of questions: 1- How can neural and biological markers enhance our understanding of human social behavior? 2- What are the biological systems affecting social behavior? 3- How do social processes affect biological systems?
