Socialization is a continuous and lifelong process starting from birth. It is characterized by the inheritance and dissemination of rules, customs and beliefs, which are essential for an individual in order to be an active member of his society. So it can be said that socialization is the tool preserving the social and cultural characteristics. This learning process is performed and influenced by several factors such as parents, family and other social networks.
Children observe and learn which attitudes, ethics and actions are appropriate for individuals who are members of a specific culture. A simple example is a child who saw his mother making a discriminating statement about someone who belongs to a minority group and then thinks that this behavior is normal and as a result the child will keep expressing the same discriminating opinion to others.
There are three types of socialization: group, gender and cultural. Firstly, according to group socialization an individual's peer groups, except from parental figures, affects his or her personality and behavior during adulthood. Secondly, the gender socialization leads to the learning of specific behaviors and attitudes considered suitable for each sex. Lastly, cultural socialization includes parenting practices which teaches children about their cultural history and heritage and occasionally, is referred to as development of pride.
