Psychology is the study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.
A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychologists attempt to understand the role of mental functions in individual and social behavior. Others explore the physiological and neurobiological processes that underlie cognitive functions and behaviors.
Self-harm is intentional conduct that is considered harmful to oneself. This is most commonly regarded as direct injury of one's own skin tissues usually without a suicidal intention. Other terms such as cutting, self-injury, and self-mutilation have been used for any self-harming behavior regardless of suicidal intent. Common forms of self-harm include damaging the skin with a sharp object or by scratching, hitting, or burning. The exact bounds of self-harm are imprecise, but generally exclude tissue damage that occurs as an unintended side-effect of eating disorders or substance abuse, as well as societally acceptable body modification such as tattoos and piercings.
Although self-harm is by definition non-suicidal, it may still be life-threatening. People who do self-harm are more likely to die by suicide, and self-harm is found in 40–60% of suicides. Still, only a minority of those who self-harm are suicidal. (Full article...)
