Proprioception

Proprioception
The cerebellum is largely responsible for coordinating the unconscious aspects of proprioception. Proprioception (/ˌproʊpri.ɵˈsɛpʃən/ PRO-pree-o-SEP-shən), from Latin proprius, meaning "one's own", "individual" and perception, is the sense of the relative position of neighbouring parts of the body and strength of effort being employed in movement.[1] It is provided by proprioceptors in skeletal striated muscles and in joints. It is distinguished from exteroception, by which one perceives the outside world, and interoception, by which one perceives pain, hunger, etc., and the movement of internal organs. History of study[edit] In 1906, Charles Scott Sherrington published a landmark work that introduced the terms "proprioception", "interoception", and "exteroception". Components[edit] Kinesthesia is a key component in muscle memory and hand-eye coordination, and training can improve this sense (see blind contour drawing).

Sense of agency The "sense of agency" (SA) refers to the subjective awareness that one is initiating, executing, and controlling one's own volitional actions in the world.[1] It is the pre-reflective awareness or implicit sense that it is I who is executing bodily movement(s) or thinking thoughts. In normal, non-pathological experience, the SA is tightly integrated with one's "sense of ownership" (SO), which is the pre-reflective awareness or implicit sense that one is the owner of an action, movement or thought. If someone else were to move your arm (while you remained passive) you would certainly have sensed that it were your arm that moved and thus a sense of ownership (SO) for that movement. However, you would not have felt that you were the author of the movement; you would not have a sense of agency (SA).[2] Definition[edit] Neuroscience of the sense of agency[edit] Agency and psychopathology[edit] Marc Jeannerod proposed that the process of self-recognition operates covertly and effortlessly.

Pareidolia A satellite photo of a mesa in Cydonia, often called the Face on Mars. Later imagery from other angles did not contain the illusion. Examples[edit] Projective tests[edit] The Rorschach inkblot test uses pareidolia in an attempt to gain insight into a person's mental state. The Rorschach is a projective test, as it intentionally elicits the thoughts or feelings of respondents which are "projected" onto the ambiguous inkblot images. Art[edit] In his notebooks, Leonardo da Vinci wrote of pareidolia as a device for painters, writing "if you look at any walls spotted with various stains or with a mixture of different kinds of stones, if you are about to invent some scene you will be able to see in it a resemblance to various different landscapes adorned with mountains, rivers, rocks, trees, plains, wide valleys, and various groups of hills. Religious[edit] Divination[edit] Various European ancient divination practices involve the interpretation of shadows cast by objects. Fossils[edit]

Semantic satiation History and research[edit] The phrase "semantic satiation" was coined by Leon Jakobovits James in his doctoral dissertation at McGill University, Montreal, Canada awarded in 1962.[1] Prior to that, the expression "verbal satiation" had been used along with terms that express the idea of mental fatigue. The dissertation listed many of the names others had used for the phenomenon: "Many other names have been used for what appears to be essentially the same process: inhibition (Herbert, 1824, in Boring, 1950), refractory phase and mental fatigue (Dodge, 1917; 1926a), lapse of meaning (Bassett and Warne, 1919), work decrement (Robinson and Bills, 1926), cortical inhibition (Pavlov, 192?) The explanation for the phenomenon was that verbal repetition repeatedly aroused a specific neural pattern in the cortex which corresponds to the meaning of the word.

Milgram experiment The experimenter (E) orders the teacher (T), the subject of the experiment, to give what the latter believes are painful electric shocks to a learner (L), who is actually an actor and confederate. The subject believes that for each wrong answer, the learner was receiving actual electric shocks, though in reality there were no such punishments. Being separated from the subject, the confederate set up a tape recorder integrated with the electro-shock generator, which played pre-recorded sounds for each shock level.[1] The experiments began in July 1961, three months after the start of the trial of German Nazi war criminal Adolf Eichmann in Jerusalem. The experiment[edit] Milgram Experiment advertisement Three individuals were involved: the one running the experiment, the subject of the experiment (a volunteer), and a confederate pretending to be a volunteer. The subjects believed that for each wrong answer, the learner was receiving actual shocks. Results[edit] Criticism[edit] Ethics[edit]

Stanford prison experiment The Stanford prison experiment (SPE) was a study of the psychological effects of becoming a prisoner or prison guard. The experiment was conducted at Stanford University from August 14–20, 1971, by a team of researchers led by psychology professor Philip Zimbardo.[1] It was funded by the US Office of Naval Research[2] and was of interest to both the US Navy and Marine Corps as an investigation into the causes of conflict between military guards and prisoners. Goals and methods[edit] Zimbardo and his team aimed to test the hypothesis that the inherent personality traits of prisoners and guards are the chief cause of abusive behavior in prison. Participants were recruited and told they would participate in a two-week prison simulation. The experiment was conducted in the basement of Jordan Hall (Stanford's psychology building). The researchers held an orientation session for guards the day before the experiment, during which they instructed them not to physically harm the prisoners. [edit]

Operant conditioning Diagram of operant conditioning Operant conditioning separates itself from classical conditioning because it is highly complex, integrating positive and negative conditioning into its practices; whereas, classical conditioning focuses only on either positive or negative conditioning but not both together. Another dubbing of operant conditioning is instrumental learning. Instrumental conditioning was first discovered and published by Jerzy Konorski and was also referred to as Type II reflexes. Mechanisms of instrumental conditioning suggest that the behavior may change in form, frequency, or strength. Operant behavior operates on the environment and is maintained by its antecedents and consequences, while classical conditioning is maintained by conditioning of reflexive (reflex) behaviors, which are elicited by antecedent conditions.

Macdonald triad The Macdonald triad (also known as the triad of sociopathy or the homicidal triad) is a set of three behavioral characteristics that has been suggested, if all three or any combination of two, are present together, to be predictive of or associated with, later violent tendencies, particularly with relation to serial offenses. The triad was first proposed by psychiatrist J.M. Macdonald in "The Threat to Kill", a 1963 paper in the American Journal of Psychiatry.[1] Small-scale studies conducted by psychiatrists Daniel Hellman and Nathan Blackman, and then FBI agents John E. Douglas and Robert K. Ressler along with Dr. The triad links cruelty to animals, obsession with fire setting, and persistent bedwetting past a certain age, to violent behaviors, particularly homicidal behavior and sexually predatory behavior.[5] Some other studies claim to have not found statistically significant links between the triad and violent offenders.

Madonna–whore complex From Wikipedia, the free encyclopedia Inability to maintain sexual arousal within a committed, loving relationship Causes[edit] Freud argued that the Madonna–whore complex was caused by a split between the affectionate and the sexual currents in male desire.[5] Oedipal and castration anxiety fears prohibit the affection felt for past incestuous objects from being attached to women who are sensually desired: "The whole sphere of love in such persons remains divided in the two directions personified in art as sacred and profane (or animal) love".[5] In order to minimize anxiety, the man categorizes women into two groups: women he can admire and women he finds sexually attractive. Whereas the man loves women in the former category, he despises and devalues the latter group.[6] Psychoanalyst Richard Tuch suggests that Freud offered at least one alternative explanation for the Madonna–whore complex: History[edit] See also[edit] References[edit] Further reading[edit]

Self-awareness Self-awareness is the capacity for introspection and the ability to recognize oneself as an individual separate from the environment and other individuals.[1] It is not to be confused with consciousness. While consciousness is being aware of one’s environment and body and lifestyle, self-awareness is the recognition of that consciousness.[2] Neurobiological basis[edit] There are questions regarding what part of the brain allows us to be self-aware and how we are biologically programmed to be self- aware. Animals[edit] Studies have been done mainly on primates to test if self-awareness is present. The ‘Red Spot Technique’ created and experimented by Gordon Gallup[6] studies self-awareness in animals (primates). Researchers used the Mark test or Mirror test [12] to study the magpie’s self awareness. A few slight occurrences of behavior towards the magpie's own body happened in the trial with the black mark and the mirror. Psychology[edit] Developmental stages[edit] Level 0: Confusion. [edit]

False consensus effect Attributional type of cognitive bias In psychology, the false consensus effect, also known as consensus bias, is a pervasive cognitive bias that causes people to “see their own behavioral choices and judgments as relatively common and appropriate to existing circumstances”. In other words, they assume that their personal qualities, characteristics, beliefs, and actions are relatively widespread through the general population. This false consensus is significant because it increases self-esteem (overconfidence effect). It can be derived from a desire to conform and be liked by others in a social environment. The false consensus effect has been widely observed and supported by empirical evidence. Major theoretical approaches[edit] The false-consensus effect can be traced back to two parallel theories of social perception, "the study of how we form impressions of and make inferences about other people". Selective exposure and cognitive availability[edit] Salience and focus of attention[edit]

Frequency illusion Cognitive bias Frequency illusion, also known as the Baader–Meinhof phenomenon or frequency bias, is a cognitive bias referring to the tendency to notice something more often after noticing it for the first time, leading to the belief that it has an increased frequency of occurrence.[1][2][3] The illusion is a result of increased awareness of a phrase, idea, or object – for example, hearing a song more often or seeing red cars everywhere.[4][5] The Baader-Meinhof group, which the phenomenon is named after, was a far-left German terrorist organization active in the 1970s. The name “Baader-Meinhof phenomenon” was coined in 1994 by an online message board user, who, after mentioning the name of the German terrorist group Baader-Meinhof once, kept noticing it, and posted on the forum about their experience. This led to other readers of the message board sharing their own experiences of the phenomenon, leading it to gain recognition. Causes[edit] Selective attention[edit] Confirmation bias[edit]

Crab mentality From Wikipedia, the free encyclopedia Metaphor about spiteful attitude Crab mentality, also known as crab theory,[1][2] crabs in a bucket[a] mentality, or the crab-bucket effect, is a way of thinking best described by the phrase "if I can't have it, neither can you".[3] The metaphor is derived from anecdotal claims about the behavior of crabs when they are trapped in a bucket: while any one crab can easily start to climb out,[4] it will nonetheless be pulled back in by the others, ensuring the group's collective demise.[5][6][7] Note[edit] ^ also barrel, basket, or pot See also[edit] References[edit] Further reading[edit]

Kirkbride Plan Mental asylum design created by Thomas Kirkbride The Kirkbride Plan was a system of mental asylum design advocated by American psychiatrist Thomas Story Kirkbride (1809–1883) in the mid-19th century. The asylums built in the Kirkbride design, often referred to as Kirkbride Buildings (or simply Kirkbrides), were constructed during the mid-to-late-19th century in the United States. The structural features of the hospitals as designated by Kirkbride were contingent on his theories regarding the healing of the mentally ill, in which environment and exposure to natural light and air circulation were crucial. The first hospital designed under the Kirkbride Plan was the Trenton State Hospital in Trenton, New Jersey, constructed in 1848. Numerous Kirkbride structures still exist, though many have been demolished or partially-demolished and repurposed.

Apophenia Apophenia /æpɵˈfiːniə/ is the experience of perceiving patterns or connections in random or meaningless data. The term is attributed to Klaus Conrad[1] by Peter Brugger,[2] who defined it as the "unmotivated seeing of connections" accompanied by a "specific experience of an abnormal meaningfulness", but it has come to represent the human tendency to seek patterns in random information in general, such as with gambling and paranormal phenomena.[3] Meanings and forms[edit] In 2008, Michael Shermer coined the word "patternicity", defining it as "the tendency to find meaningful patterns in meaningless noise".[6][7] In The Believing Brain (2011), Shermer says that we have "the tendency to infuse patterns with meaning, intention, and agency", which Shermer calls "agenticity".[8] Statistics[edit] Pareidolia[edit] Pareidolia is a type of apophenia involving the perception of images or sounds in random stimuli, for example, hearing a ringing phone while taking a shower.
