Learning theories seek to explain what is learned and how learning takes place regarding criminal behavior. Sutherland's differential association theory proposes that criminal behavior is learned through interaction with others and is influenced by the meanings given to criminal acts by those we associate with. Cultural and subcultural theories expanded on this, arguing that values and behaviors are influenced by one's culture or subculture. More recent theorists like Anderson have examined how living conditions in inner cities can influence codes of respect and violence.
