Please answer the following question: Information:  - A psychologist is a professional who evaluates and studies behavior and mental processes (see also psychology). Typically, psychologists must have completed a university degree in psychology, which is a master's degree in some countries and a doctorate in others. This definition of psychologist is non-exclusive; in most jurisdictions, members of other professions (such as counselors and psychiatrists) can also evaluate, diagnose, treat, and study mental processes. Some psychologists, such as clinical and counseling psychologists, provide mental health care, and some psychologists, such as social or organizational psychologists conduct research and provide consultation services.  - The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord. The central nervous system is so named because it integrates information it receives from, and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric animalsthat is, all multicellular animals except sponges and radially symmetric animals such as jellyfishand it contains the majority of the nervous system. Many consider the retina and the optic nerve (2nd cranial nerve), as well as the olfactory nerves (1st) and olfactory epithelium as parts of the CNS, synapsing directly on brain tissue without intermediate ganglia. Following this classification the olfactory epithelium is the only central nervous tissue in direct contact with the environment, which opens up for therapeutic treatments.  - Psychotherapy is the use of psychological methods, particularly when based on regular personal interaction, to help a person change and overcome problems in desired ways. Psychotherapy aims to improve an individual's well-being and mental health, to resolve or mitigate troublesome behaviors, beliefs, compulsions, thoughts, or emotions, and to improve relationships and social skills. Certain psychotherapies are considered evidence-based for treating some diagnosed mental disorders.  - Arthur Janov (born August 21, 1924) is an American psychologist, psychotherapist, and the creator of primal therapy, a treatment for mental illness that involves repeatedly descending into, feeling, and experiencing long-repressed childhood pain. Janov directs a psychotherapy institute called the Primal Center in Santa Monica, California. Janov is the author of many books, most notably "The Primal Scream" (1970).  - Pain is a distressing feeling often caused by intense or damaging stimuli, such as stubbing a toe, burning a finger, putting alcohol on a cut, or bumping the "funny bone". Because it is a complex, subjective phenomenon, defining pain has been a challenge. The International Association for the Study of Pain's widely used definition states: "Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage." In medical diagnosis, pain is regarded as a symptom of an underlying condition.  - The Primal Scream . Primal Therapy : The Cure for Neurosis is a 1970 book by Arthur Janov , the inventor of Primal therapy .  - Santa Monica is a beachfront city in western Los Angeles County, California, United States. Situated on Santa Monica Bay, it is bordered on three sides by the city of Los Angeles  Pacific Palisades to the north, Brentwood on the northeast, Sawtelle on the east, Mar Vista on the southeast, and Venice on the south. The Census Bureau population for Santa Monica in 2010 was 89,736.  - Primal therapy is a trauma-based psychotherapy created by Arthur Janov, who argues that neurosis is caused by the repressed pain of childhood trauma. Janov argues that repressed pain can be sequentially brought to conscious awareness and resolved through re-experiencing the incident and fully expressing the resulting pain during therapy. In therapy, the patient recalls and reenacts a particularly disturbing past experience usually occurring early in life and expresses normally repressed anger or frustration especially through spontaneous and unrestrained screams, hysteria, or violence. Primal therapy was developed as a means of eliciting the repressed pain; the term "Pain" is capitalized in discussions of primal therapy when referring to any repressed emotional distress and its purported long-lasting psychological effects. Janov criticizes the talking therapies as they deal primarily with the cerebral cortex and higher-reasoning areas and do not access the source of Pain within the more basic parts of the central nervous system.    What is the relationship between 'the primal scream' and 'psychology'?
