Psychology is the scientific 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.
Insanity in English law is a defence to criminal charges based on the idea that the defendant was unable to understand what he was doing, or, that he was unable to understand that what he was doing was wrong.
The defence comes in two forms; where the defendant claims he was insane at the time of the crime, and where the defendant asserts he is insane at the time of trial. In the first situation, the defendant must show that he was either suffering from a disease which damaged the functioning of the mind and led to a defect of reason that prevented him from understanding what he was doing, or that he could not tell that what he was doing was wrong. In the second situation, the test is whether or not the defendant can differentiate between "guilty" and "not guilty" verdicts, instruct counsel and recognise the charges he is facing. If successful, he is likely to be detained under the Criminal Procedure (Insanity) Act 1964, although judges have a wide discretion as to what to do. (Full article...)

He was the first to use a double-blind procedure in investigating physical and psychological effects of consumption of tea, coffee, alcohol and drugs. For a time he directed centres for psychological studies at two colleges, and he was made a Fellow of St John's College, Cambridge. He also participated in the Torres Strait Islands expedition of 1898 and his consequent seminal work on the subject of kinship. (Full article...)
