Forensic Psychology, a subfield of psychology, involves the application of psychological knowledge and methods to both civil and criminal legal questions. Traditionally, it has a broad definition as well as a narrow definition.The broader classification states that forensic psychology involves the application of all psychological areas of research to the legal field, while the narrower definition characterizes forensic psychology as “The application of clinical specialties to legal institutions and people who come into contact with the law.” While the American Psychological Association (APA) officially recognized forensic psychology as a specialty under the narrower definition in 2001, the Specialty Guidelines for Forensic Psychologists previously acknowledged by the APA in 1991 were revised in 2013 to include all subfields of psychology (e.g. social, clinical, experimental, counseling, neuropsychology) that apply "the scientific, technical, or specialized knowledge of psychology to the law."
