Schizotypy
In psychology, schizotypy is a theoretical concept that posits a continuum (theory), continuum of personality psychology, personality characteristics and experiences, ranging from normal dissociative, imaginative states to extreme states of mind related to psychosis, especially schizophrenia. The continuum of personality proposed in schizotypy is in contrast to a categorical view of psychosis, wherein psychosis is considered a particular (usually pathological) state of mind, which the person either has or does not have. Development of the concept The categorical view of psychosis is most associated with Emil Kraepelin, who created criteria for the medical diagnosis and classification of different forms of psychotic illness. Particularly, he made the distinction between dementia praecox (now called schizophrenia), manic depression, manic depressive insanity and non-psychotic states. Modern diagnostic systems used in psychiatry (such as the Diagnostic and Statistical Manual of Ment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anhedonia
Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning. In the ''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' (DSM-5), anhedonia is a component of depressive disorders, substance-related disorders, psychotic disorders, and personality disorders, where it is defined by either a reduced ability to experience pleasure, or a diminished interest in engaging in previously pleasurable activities. While the ''International Statistical Classification of Diseases and Related Health Problems, Tenth Revision'' (ICD-10) does not explicitly mention anhedonia, the depressive symptom analogous to anhedonia as described in the DSM-5 ...

Gordon Claridge
Dr. Gordon Sidney Claridge was a British psychologist and author, best known for his theoretical and empirical work on the concept of schizotypy or psychosis-proneness. Biography Claridge took his first degree in Psychology at University College, London, in 1953. His PhD work was at the Institute of Psychiatry, London, jointly supervised by Hans Eysenck and Neil O’Connor. He qualified under in-service training as a clinical psychologist, and from 1957-61 worked as Eysenck’s Research Assistant, based in the Royal Victoria Military Hospital, Netley, Southampton. Claridge then moved to Bristol as Head of Clinical Psychology at Barrow Hospital and part-time lecturer in the Bristol University Department of Psychology. From 1964-74 he ran the Glasgow University clinical psychology training course as (eventually) Reader in Clinical Psychology. He was awarded a DSc from Glasgow University in 1971. In 1974 Claridge moved to Oxford as University Lecturer in Abnormal Psychology a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizoid Personality Disorder
Schizoid personality disorder (, often abbreviated as SzPD or ScPD) is a personality disorder characterized by a lack of interest in social relationships, a tendency toward a solitary or sheltered lifestyle, secretiveness, emotional coldness, detachment, and apathy. Affected individuals may be unable to form intimate attachments to others and simultaneously possess a rich and elaborate but exclusively internal fantasy world. Other associated features include stilted speech, a lack of deriving enjoyment from most activities, feeling as though one is an "observer" rather than a participant in life, an inability to tolerate emotional expectations of others, apparent indifference when praised or criticized, being on the asexual spectrum, and idiosyncratic moral or political beliefs. Symptoms typically start in late childhood or adolescence. The cause of SzPD is uncertain, but there is some evidence of links and shared genetic risk between SzPD, other cluster A personality diso ...

Creativity
Creativity is the ability to form novel and valuable Idea, ideas or works using one's imagination. Products of creativity may be intangible (e.g. an idea, scientific theory, Literature, literary work, musical composition, or joke), or a physical object (e.g. an invention, dish or meal, piece of Jewellery, jewelry, costume, a painting). Creativity may also describe the ability to find Creative problem-solving, new solutions to problems, or new methods to accomplish a goal. Therefore, creativity enables people to Solves problem, solve problems in new ways. Most ancient cultures (including Ancient Greece, History of China#Ancient China, Ancient China, and Outline of ancient India, Ancient India) lacked the concept of creativity, seeing art as a form of discovery rather than a form of creation. In the Judeo-Christian-Islamic tradition, creativity was seen as the sole province of God, and human creativity was considered an expression of God's work; the modern conception of creativi ...

Psychoticism
Psychoticism is one of the three traits used by the psychologist Hans Eysenck in his outdated P–E–N model ( psychoticism, extraversion and neuroticism) model of personality. Psychoticism includes the traits of "aggression, coldness, egocentrism, impulsivity, lack of empathy, tough-mindedness, and being antisocial." Nature Psychoticism is conceptually similar to the ''constraint'' factor in Tellegen's three-factor model of personality. Psychoticism may be divided into narrower traits such as impulsivity and sensation-seeking. These may in turn be further subdivided into even more specific traits. For example, impulsivity may be divided into narrow impulsivity (unthinking responsivity), risk taking, non-planning, and liveliness. Sensation seeking has also been analysed into a number of separate facets. Eysenck argued that there might be a correlation between psychoticism and creativity. Critics Critics of the trait have suggested that the trait is too heterogeneous to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Diagnosis
Medical diagnosis (abbreviated Dx, Dx, or Ds) is the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as a diagnosis with the medical context being implicit. The information required for a diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more diagnostic procedures, such as medical tests, are also done during the process. Sometimes the posthumous diagnosis is considered a kind of medical diagnosis. Diagnosis is often challenging because many signs and symptoms are nonspecific. For example, redness of the skin ( erythema), by itself, is a sign of many disorders and thus does not tell the healthcare professional what is wrong. Thus differential diagnosis, in which several possible explanations are compared and contrasted, must be performed. This involves the correlation of various pieces of information followed by the recognition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallucination
A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from " delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Hallucinations can occur in any sensory modality— visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive. Hallucinations are referred to as multimodal if multiple sensory modalities occur. A mild form of hallucination is known as ...

Schizoaffective Disorder
Schizoaffective disorder is a mental disorder characterized by symptoms of both schizophrenia (psychosis) and a mood disorder, either bipolar disorder or depression. The main diagnostic criterion is the presence of psychotic symptoms for at least two weeks without prominent mood symptoms. Common symptoms include hallucinations, delusions, disorganized speech and thinking, as well as mood episodes. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, bipolar I disorder, schizophreniform disorder, or schizophrenia. This is a problem as treatment and prognosis differ greatly for most of these diagnoses. Many people with schizoaffective disorder have other mental disorders including anxiety disorders. There are three forms of schizoaffective disorder: bipolar (or manic) type (marked by symptoms of schizophrenia and mania), depressive type (marked by symptoms of schizophrenia and depression), and mixed type (marked by symptoms ...

Sandor Rado
Sandor Rado ( ; 8 January 1890, Kisvárda – 14 May 1972, New York City) was a Hungarian psychoanalyst of the second generation, who moved to the United States in the 1930s. According to Peter Gay, "Budapest produced some of the most conspicuous talents in the analytic profession: in addition to Ferenczi, these included Franz Alexander nd SándorRadó." Rado is known for having coined the term " schizotype" in 1956 as an abbreviation of "schizophrenic phenotype". These writings played a foundational role in modern conceptualizations of schizotypy, and the genetic etiology of schizophrenia and psychosis. Life Rado was initially trained as a medical doctor. Later Sandor Rado met Sigmund Freud in 1915 and decided to become a psychoanalyst. He was analysed first by a former analysand of Freud, E. Revesz, and then, after his move to Berlin, by Karl Abraham. Among his own distinguished analysands were Wilhelm Reich and " Heinz Hartmann, the most prominent among the ego psycholog ...

Premorbid
Premorbidity refers to the state of functionality prior to the onset of a disease or illness. It is most often used in relation to psychological function (e.g. premorbid personality or premorbid intelligence), but can also be used in relation to other medical conditions (e.g. premorbid lung function or premorbid heart rate). Psychology In psychology, premorbidity is most often used in relation to changes in personality, intelligence or cognitive function. Changes in personality are common in cases of traumatic brain injury involving the frontal lobes, the most famous example of this is the case of Phineas Gage who survived having a tamping iron shot through his head in a railway construction accident. Declines from premorbid levels of intelligence and other cognitive functions are observed in stroke, traumatic brain injury, and dementia as well as in mental illnesses such as depression and schizophrenia. Other usage in psychology include premorbid adjustment which has importan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Process
Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms. Regulation of biological processes occurs when any process is modulated in its frequency, rate or extent. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. * Homeostasis: regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature * Biological organization, Organization: being structurally composed of one or more cell (biology), cells – the basic units of life * Metabolism: transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolis ...

Cognitive
Cognition is the "mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, imagination, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem-solving and decision-making, comprehension and production of language. Cognitive processes use existing knowledge to discover new knowledge. Cognitive processes are analyzed from very different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) are synthesized in the developing field of cognitive science, a progressively auton ...
