Capgras Syndrome
Capgras delusion or Capgras syndrome is a psychiatric disorder in which a person holds a delusion that a friend, spouse, parent, or other close family member (or pet) has been replaced by an identical impostor. It is named after Joseph Capgras (1873–1950), the French psychiatrist who first described the disorder. The Capgras delusion is classified as a delusional misidentification syndrome, a class of delusional beliefs that involves the misidentification of people, places, or objects. It can occur in acute, transient, or chronic forms. Cases in which patients hold the belief that time has been "warped" or "substituted" have also been reported. The delusion most commonly occurs in individuals diagnosed with schizophrenia but has also been seen in brain injury, dementia with Lewy bodies, and other dementia. It presents often in individuals with a neurodegenerative disease, particularly at an older age. It has also been reported as occurring in association with diabetes, hypo ...

Psychiatry
Psychiatry is the specialty (medicine), medical specialty devoted to the diagnosis, prevention, and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry. Initial psychiatric assessment of a person typically begins with a Medical history, case history and mental status examination. Physical examinations and Psychological testing, psychological tests may be conducted. On occasion, neuroimaging or other Neurophysiology, neurophysiological techniques are used. Mental disorders are often diagnosed in accordance with clinical concepts listed in diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited and used by the World Health Organization (WHO) and the widely used ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013 which re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Opinion
A second opinion is an opinion on a matter disputed by two or more parties. Law In legal cases, a second opinion which contradicts the opinion of a jointly retained expert may be disregarded as not being impartial. Consumer rights In cases such as car repairs, a second opinion should be obtained in writing, and the original garage given an opportunity to rectify matters. In the case of clients' disputes with domestic building contractors, the builder may seek a second opinion to confirm their view. Medicine A second opinion can be a visit to a physician other than the one a patient has previously been seeing in order to get more information or to hear a differing point of view. Some reasons for which a patient may seek out a second opinion include: *Physician recommends surgery. *Physician diagnoses patient with serious illness (such as cancer). *Physician recommends a treatment for the patient other than what the patient believes is necessary. *When physician recomme ...

William Hirstein
William Hirstein is an American philosopher primarily interested in philosophy of mind, philosophy of language, metaphysics, cognitive science, and analytic philosophy. He is a professor of philosophy at Elmhurst University. Training William Hirstein received his Ph.D. in philosophy at the University of California, Davis under the direction of Richard Wollheim. He then did post-doctoral work under the supervision of Patricia Churchland and Vilayanur S. Ramachandran at the University of California, San Diego, exploring neurological syndromes that lead to confabulation, such as in split-brain patients, and patients with anosognosia or Capgras delusion. Theory of confabulation Hirstein draws heavily on the interaction between his philosophical training and his clinical experience in his 2005 book ''Brain Fiction'' to develop a comprehensive epistemic theory of the neural basis of confabulation, and argues that prefrontal executive processes fail to correct false memories or perce ...

Galvanic Skin Response
Electrodermal activity (EDA) is the property of the human body that causes continuous variation in the electrical characteristics of the skin. Historically, EDA has also been known as skin conductance, galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR), sympathetic skin response (SSR) and skin conductance level (SCL). The long history of research into the active and passive electrical properties of the skin by a variety of disciplines has resulted in an excess of names, now standardized to electrodermal activity (EDA). The traditional theory of EDA holds that skin resistance varies with the state of sweat glands in the skin. Sweating is controlled by the sympathetic nervous system, and skin conductance is an indication of psychological or physiological arousal. If the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin condu ...

Double Dissociation
In neuropsychology, dissociation involves identifying the neural substrate of a particular brain function through identification of case studies, neuroimaging, or neuropsychological testing. Dissociation types Single dissociation When dissecting complex mental tasks into their subcomponents, a researcher can establish a "single dissociation" between functions. This is done by demonstrating that a lesion to brain structure A disrupts function X but not function Y. Such a demonstration allows one to infer that function X and function Y are independent of each other in some way. Dr. Oliver Sacks has described many famous cases of dissociation in his books. Patient D.F., for example, was unable to place a card in a slot, but could do so when told to place it "as if mailing a letter". From this the conclusion was drawn that judging orientation is one ability (which D.F. had lost) and visual control of an action another (which D.F. could still do).E.

Hadyn Ellis
Hadyn Ellis CBE DSc (25 October 1945 – 2 November 2006) was a Welsh psychologist who was influential in the field of face processing and who had some 160 publications to his name. For the largest part of his career he worked at Cardiff University, where he became pro-vice chancellor for research in 1994. He also made significant contributions to research strategy at the ESRC. His research into face perception had significant contribution to eyewitness testimony and also the understanding of delusions of misidentification such as Capgras delusion. Ellis is also considered to be the person who coined the term cognitive neuropsychiatry. During his career he also wrote many books, including ''Validation in Psychology: Research Perspectives'' and ''Perceiving and Remembering Faces''. After his death from bowel cancer Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the lar ...

Autonomic Nervous System
The autonomic nervous system (ANS), formerly referred to as the vegetative nervous system, is a division of the peripheral nervous system that supplies internal organs, smooth muscle and glands. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, its force of contraction, digestion, respiratory rate, pupillary response, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response. The autonomic nervous system is regulated by integrated reflexes through the brainstem to the spinal cord and organs. Autonomic functions include control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and certain reflex actions such as coughing, sneezing, swallowing and vomiting. Those are then subdivided into other areas and are also linked to autonomic subsystems and the peripheral nervous system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Face Perception
Facial perception is an individual's understanding and interpretation of the face. Here, perception implies the presence of consciousness and hence excludes automated facial recognition systems. Although facial recognition is found in other species, this article focuses on facial perception in humans. The perception of facial features is an important part of social cognition. Information gathered from the face helps people understand each other's identity, what they are thinking and feeling, anticipate their actions, recognize their emotions, build connections, and communicate through body language. Developing facial recognition is a necessary building block for complex societal constructs. Being able to perceive identity, mood, age, sex, and race lets people mold the way we interact with one another, and understand our immediate surroundings. Though facial perception is mainly considered to stem from visual intake, studies have shown that even people born blind can learn fa ...
