live as close to a normal life as possible. Normalization also included the concept of the developmental model‚ which stated that everyone has a capacity to learn and grown‚ regardless of their disability. However the developmental model had some negative consequences for education‚ since it encouraged educators to teach individuals with disabilities based on infant and early childhood curriculum.

Some people would argue that classical theories do not play a large role in more recent studies‚ however‚ concepts such as free will and determinism from Glaser (1977) and differential association theory from Sutherland (1947) have shown reason to believe they are still relevant in cases from the 1960s‚ 1980s‚ as well as recent topics today. These classical theories are ways in which researchers attempt to ‘explain criminal behavior’‚ especially when it comes to woman killers and doubly deviant women

Soft Determinism Stace’s theory of compatibilism has to deal with free will and its consistency with determinism. Soft determinism is the thought that coherent humans should be held responsible for their actions if those actions were voluntary. Actions can be both free and determined while still having the ability to be held as morally responsible. Hard determinism on the other hand states that every action is caused therefore making a person unable to be held responsible for anything they
