Biological inheritance and environmental factors are the two main determinants of personality development. Biological inheritance includes physical traits and innate capacities that set limits on what a person can do. Environmental factors refer to the influence of family, social groups, school and other external influences that a person interacts with from a young age. Each group exerts pressure that shapes how a person behaves differently in various situations and conditions. Deviant behavior refers to actions that differ significantly from social norms and can be tolerated, approved, or disapproved depending on cultural and social contexts.
