Deese–Roediger–McDermott Paradigm
The Deese–Roediger–McDermott (DRM) paradigm is a procedure in cognitive psychology used to study false memory in humans. The procedure was pioneered by James Deese in 1959, but it was not until Henry L. Roediger III and Kathleen McDermott extended the line of research in 1995 that the paradigm became popular. The procedure typically involves the oral presentation of a list of related words (e.g., ''bed, rest, awake, tired, dream, wake, snooze, blanket, doze, slumber, snore, nap, peace, yawn, drowsy'') and then requires the subject to remember as many words from the list as possible. Typical results show that subjects recall a related but absent word (e.g., ''sleep''), known as a 'lure', with the same frequency as other presented words. When asked about their experience after the test, about half of all participants report that they are sure that they remember hearing the lure, indicating a false memory – a memory for an event that never occurred. The simplicity of the para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Psychology
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s in a break from behaviorism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. The domain of cognitive psychology overlaps with that of cognitive science, which takes a more interdisciplinary approach and includes studies of non-human subjects and artificial intelligence. History Philosophically, ruminations on the human mind and its processes have been around since the times of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source-monitoring Error
A source-monitoring error is a type of memory error where the source of a memory is incorrectly attributed to some specific recollected experience. For example, individuals may learn about a current event from a friend, but later report having learned about it on the local news, thus reflecting an incorrect source attribution. This error occurs when normal perceptual and reflective processes are disrupted, either by limited encoding of source information or by disruption to the judgment processes used in source-monitoring. Depression, high stress levels and damage to relevant brain areas are examples of factors that can cause such disruption and hence source-monitoring errors.Johnson, M.K., Hashtroudi, S., Lindsay, D.S. (1993). Source Monitoring. ''Psychological Bulletin'', 114(1), 3–28 Introduction One of the key ideas behind source-monitoring is that rather than receiving an actual label for a memory during processing, a person's memory records are activated and evaluated throu ...

Attachment In Adults
In psychology, the theory of attachment can be applied to adult relationships including friendships, emotional affairs, adult romantic or carnal relationships or platonic relationships, and, in some cases, relationships with inanimate objects ("transitional objects"). Attachment theory, initially studied in the 1960s and 1970s primarily in the context of children and parents, was extended to adult relationships in the late 1980s. The working models of children found in Bowlby's attachment theory form a pattern of interaction likely to continue influencing adult relationships. Four main styles of attachment have been identified in adults: *secure *anxious-preoccupied *dismissive-avoidant *fearful-avoidant Investigators have explored the organization and the stability of mental ''working models'' that underlie these attachment styles. They have also explored how attachment impacts relationship outcomes and how attachment functions in relationship dynamics. Extending attachment t ...

Dissociative Experiences Scale
The Dissociative Experiences Scale (DES) is a psychological self-assessment questionnaire that measures dissociative symptoms. Background It contains twenty-eight questions and returns an overall score as well as four sub-scale results. DES is intended to be a screening test, since only 17% of patients with scores over 30 will be diagnosed with having dissociative identity disorder Dissociative identity disorder (DID), better known as multiple personality disorder or multiple personality syndrome, is a mental disorder characterized by the presence of at least two distinct and relatively enduring personality states. The di .... Patients with lower scores above normal may have other post-traumatic conditions. The DES-II contains the same questions but with a different response scale.

Fantasy Prone Personality
Fantasy prone personality (FPP) is a disposition or personality trait in which a person experiences a lifelong, extensive, and deep involvement in fantasy. This disposition is an attempt, at least in part, to better describe "overactive imagination" or "living in a dream world". An individual with this trait (termed a fantasizer) may have difficulty differentiating between fantasy and reality and may experience hallucinations, as well as self-suggested psychosomatic symptoms. Closely related psychological constructs include daydreaming, absorption and eidetic memory. History American psychologists Sheryl C. Wilson and Theodore X. Barber first identified FPP in 1981, said to apply to about 4% of the population.Wilson, S. C. & Barber, T. X. (1983).

Ecological Validity
In the behavioral sciences, ecological validity is often used to refer to the judgment of whether a given study's variables and conclusions (often collected in lab) are sufficiently relevant to its population (e.g. the "real world" context). Psychological studies are usually conducted in laboratories though the goal of these studies is to understand human behavior in the real-world. Ideally, an experiment would have generalizable results that predict behavior outside of the lab, thus having more ecological validity. Ecological validity can be considered a commentary on the relative strength of a study's implication(s) for policy, society, culture, etc. This term was originally coined by Egon Brunswik and held a very narrow meaning that has since been conceptually modified. He regarded ecological validity as the utility of a perceptual cue in predicting a property (basically how informative the cue is). For example, the movement of leaves on trees is a perceptual cue to how windy it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prototype Theory
Prototype theory is a theory of categorization in cognitive science, particularly in psychology and cognitive linguistics, in which there is a graded degree of belonging to a conceptual category, and some members are more central than others. It emerged in 1971 with the work of psychologist Eleanor Rosch, and it has been described as a "Copernican revolution" in the theory of categorization for its departure from the traditional Aristotelian categories.Coșeriu (2000) It has been criticized by those that still endorse the traditional theory of categories, like linguist Eugenio Coseriu and other proponents of the structural semantics paradigm. In this prototype theory, any given concept in any given language has a real world example that best represents this concept. For example: when asked to give an example of the concept ''furniture'', a '' couch'' is more frequently cited than, say, a ''wardrobe''. Prototype theory has also been applied in linguistics, as part of the mapping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False Memory
In psychology, a false memory is a phenomenon where someone recalls something that did not happen or recalls it differently from the way it actually happened. Suggestibility, activation of associated information, the incorporation of misinformation, and source misattribution have been suggested to be several mechanisms underlying a variety of types of false memory. Early work The false memory phenomenon was initially investigated by psychological pioneers Pierre Janet and Sigmund Freud. Freud was fascinated with memory and all the ways it could be understood, used, and manipulated. Some claim that his studies have been quite influential in contemporary memory research, including the research into the field of false memory. Pierre Janet was a French neurologist also credited with great contributions into memory research. Janet contributed to false memory through his ideas on dissociation and memory retrieval through hypnosis. In 1974, Elizabeth Loftus and John Palmer conduct ...

Spreading Activation
Spreading activation is a method for searching associative networks, biological and artificial neural networks, or semantic networks. The search process is initiated by labeling a set of source nodes (e.g. concepts in a semantic network) with weights or "activation" and then iteratively propagating or "spreading" that activation out to other nodes linked to the source nodes. Most often these "weights" are real values that decay as activation propagates through the network. When the weights are discrete this process is often referred to as marker passing. Activation may originate from alternate paths, identified by distinct markers, and terminate when two alternate paths reach the same node. However brain studies show that several different brain areas play an important role in semantic processing.Karalyn Patterson, Peter J. Nestor & Timothy T. Rogers: "Where do you know what you know?

Remember Versus Know Judgements
There is evidence suggesting that different processes are involved in remembering something versus knowing whether it is familiar.Mickley, K.R., Kensinger, E.A. (2008). Emotional valence influences the neural correlates associated with remembering and knowing. ''Cognition, affective & behavioural neuroscience, 8(2),'' 143-152. It appears that "remembering" and "knowing" represent relatively different characteristics of memory as well as reflect different ways of using memory. To remember is the conscious ''recollection'' of many vivid contextual details, such as "when" and "how" the information was learned. Remembering utilizes episodic memory and requires a deeper level of processing (e.g. undivided attention) than knowing. Errors in recollection may be due to source-monitoring errors that prevent an individual from remembering where exactly a piece of information was received. On the other hand, source monitoring may be very effective in aiding the retrieval of episodic memories. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
