Posthypnotic Amnesia
Post-hypnotic amnesia is the inability in hypnotic subjects to recall events that took place while under hypnosis. This can be achieved by giving individuals a suggestion during hypnosis to forget certain material that they have learned, either before or during hypnosis.Barnier, A., Bryant, R. A., & Briscoe, S. (2001). Posthypnotic amnesia for material learned before or during hypnosis: Explicit and implicit memory effects. ''International Journal of Clinical and Experimental Hypnosis, 49''(4), 286–304. Individuals who are experiencing post-hypnotic amnesia cannot have their memories recovered once put back under hypnosis; it is therefore not state-dependent. Nevertheless, memories may return when presented with a pre-arranged cue. This makes post-hypnotic amnesia similar to psychogenic amnesia, as it disrupts the retrieval process of memory.Kihlstrom, J.F. (1997). Hypnosis, memory and amnesia. ''Philos Trans R Soc Lond B Biol Sci''. 352(1362), 1727–1732. It has been suggested t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypnosis
Hypnosis is a human condition involving focused attention (the selective attention/selective inattention hypothesis, SASI), reduced peripheral awareness, and an enhanced capacity to respond to suggestion.In 2015, the American Psychological Association Division 30 defined hypnosis as a "state of consciousness involving focused attention and reduced peripheral awareness characterized by an enhanced capacity for response to suggestion". For critical commentary on this definition, see: There are competing theories explaining hypnosis and related phenomena. ''Altered state'' theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary state of consciousness. In contrast, ''non-state'' theories see hypnosis as, variously, a type of placebo effect,Kirsch, I., "Clinical Hypnosis as a Nondeceptive Placebo", pp. 211–25 in Kirsch, I., Capafons, A., Cardeña-Buelna, E., Amigó, S. (eds.), ''Clinical Hypnosis and Self-Regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proactive Interference
The interference theory is a theory regarding human memory. Interference occurs in learning. The notion is that memories encoded in long-term memory (LTM) are forgotten and cannot be retrieved into short-term memory (STM) because either memory could interfere with the other.Edwards, W. H. (2010). ''Motor Learning and Control: From Theory to Practice''. Belmont, CA: Cengage Learning. There is an immense number of encoded memories within the storage of LTM. The challenge for memory retrieval is recalling the specific memory and working in the temporary workspace provided in STM. Retaining information regarding the relevant time of encoding memories into LTM influences interference strength. There are two types of interference effects: proactive and retroactive interference. History John A. Bergström is credited with conducting the first study regarding interference in 1892. His experiment was similar to the Stroop task and required subjects to sort two decks of cards with words i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Mentalist
''The Mentalist'' is an American procedural drama television series that ran from September 23, 2008, until February 18, 2015, broadcasting 151 episodes over seven seasons, on CBS. Created by Bruno Heller, who was also its executive producer, the show follows former "psychic" Patrick Jane (Simon Baker), who is a consultant to the California Bureau of Investigation (CBI), and his boss, senior agent Teresa Lisbon (Robin Tunney). Jane uses highly developed observational skills to "read" people's minds and to solve murder cases. Synopsis The series follows Patrick Jane, an independent consultant for the California Bureau of Investigation (CBI) based in Sacramento, California. Although not an officer of the law, he uses his skills from his former career as a successful, yet admittedly fraudulent, Mediumship, psychic medium to help a team of CBI agents solve murders. The real reason for Jane's involvement with law enforcement is to track down the serial killer, known as Red John, who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterograde Amnesia
In neurology, anterograde amnesia is the inability to create new memories after an event that caused amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact. This is in contrast to retrograde amnesia, where memories created prior to the event are lost while new memories can still be created. Both can occur together in the same patient. To a large degree, anterograde amnesia remains a mysterious ailment because the precise mechanism of storing memories is not yet well understood, although it is known that the regions of the brain involved are certain sites in the temporal cortex, especially in the hippocampus and nearby subcortical regions. Signs and symptoms People with anterograde amnesic syndromes may present widely varying degrees of forgetfulness. Some with severe cases have a combined form of anterograde and retrograde amnesia, sometimes called global amnesia. In the case of drug-induce ...

Ventromedial Prefrontal Cortex
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. It also plays a role in the inhibition of emotional responses, and in the process of decision-making and self-control. It is also involved in the cognitive evaluation of morality. Anatomy While the ventromedial prefrontal cortex does not have a universally agreed on demarcation, in most sources, it is equivalent to the ventromedial reward network of Öngür and Price. This network includes Brodmann area 10, Brodmann area 14, Brodmann area 25, and Brodmann area 32, as well as portions of Brodmann area 11, Brodmann area 12, and Brodmann area 13. However, not all sources agree on the boundaries of the area. Different researchers use the term ''ventromed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychogenic Amnesia
Dissociative amnesia or psychogenic amnesia is a dissociative disorder "characterized by retrospectively reported memory gaps. These gaps involve an inability to recall personal information, usually of a traumatic or stressful nature." The concept is scientifically controversial and remains disputed. Dissociative amnesia was previously known as psychogenic amnesia, a memory disorder, which was characterized by sudden retrograde episodic memory loss, said to occur for a period of time ranging from hours to years to decades. The atypical clinical syndrome of the memory disorder (as opposed to organic amnesia) is that a person with psychogenic amnesia is profoundly unable to remember personal information about themselves; there is a lack of conscious self-knowledge which affects even simple self-knowledge, such as who they are. Psychogenic amnesia is distinguished from organic amnesia in that it is supposed to result from a nonorganic cause: no structural brain damage should be ...

Working Memory
Working memory is a cognitive system with a limited capacity that can Memory, hold information temporarily. It is important for reasoning and the guidance of decision-making and behavior. Working memory is often used synonymously with short-term memory, but some theorists consider the two forms of memory distinct, assuming that working memory allows for the manipulation of stored information, whereas short-term memory only refers to the short-term storage of information. Working memory is a theoretical concept central to cognitive psychology, neuropsychology, and neuroscience. History The term "working memory" was coined by George Armitage Miller, Miller, Eugene Galanter, Galanter, and Karl H. Pribram, Pribram, and was used in the 1960s in the context of Computational theory of mind, theories that likened the mind to a computer. In 1968, Atkinson–Shiffrin memory model, Atkinson and Shiffrin used the term to describe their "short-term store". The term short-term store was the na ...

Pierre Janet
Pierre Marie Félix Janet (; ; 30 May 1859 – 24 February 1947) was a pioneering French psychologist, physician, philosopher, and psychotherapist in the field of dissociation and traumatic memory. He is ranked alongside William James and Wilhelm Wundt as one of the founding fathers of psychology. He was the first to introduce the link between past experiences and present-day disturbances and was noted for his studies involving induced somnambulism. Biography Janet studied under Jean-Martin Charcot at the Psychological Laboratory in the Salpêtrière Hospital in Paris. He first published the results of his research in his philosophy thesis in 1889 and in his medical thesis, ''L'état mental des hystériques'', in 1892. He earned a medical doctorate the following year after completing a study on the mental state of hysterics. In 1898, Janet was appointed lecturer in psychology at the Sorbonne. In 1901, he founded the French Psychological Society and a year later h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypnotic Induction
Hypnotic induction is the process undertaken by a hypnotist to establish the state or conditions required for hypnosis to occur. Self-hypnosis is also possible, in which a subject listens to a recorded induction or plays the roles of both hypnotist and subject. Traditional techniques James Braid in the nineteenth century saw fixing the eyes on a bright object as the key to hypnotic induction. A century later, Sigmund Freud saw fixing the eyes, or listening to a monotonous sound as ''indirect'' methods of induction, as opposed to “the direct methods of influence by way of staring or stroking”—all leading however to the same result, the subject's unconscious concentration on the hypnotist. The swinging watch and intense eye gaze -- staples of hypnotic induction in film and television -- are not used in practice as the rapidly changing movements, and the obvious cliché of their application, would be distracting rather than focusing. Debates Hypnotic induction may be defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Event-related Potential
An event-related potential (ERP) is the measured brain response that is the direct result of a specific sense, sensory, cognition, cognitive, or motor system, motor event. More formally, it is any stereotyped electrophysiology, electrophysiological response to a stimulus. The study of the brain in this way provides a Invasiveness of surgical procedures, noninvasive means of evaluating brain functioning. ERPs are measured by means of electroencephalography (EEG). The magnetoencephalography (MEG) equivalent of ERP is the ERF, or event-related field. Evoked potentials and induced potentials are subtypes of ERPs. History With the discovery of the electroencephalogram (EEG) in 1924, Hans Berger revealed that one could measure the electrical activity of the human brain by placing electrodes on the scalp and amplifying the signal. Changes in voltage can then be plotted over a period of time. He observed that the voltages could be influenced by external events that stimulated the sense ...

Recognition Memory
Recognition memory, a subcategory of explicit memory, is the ability to recognize previously encountered events, objects, or people.Medina, J. J. (2008)The biology of recognition memory. ''Psychiatric Times''. When the previously experienced event is reexperienced, this environmental content is matched to stored memory representations, eliciting matching signals. As first established by psychology experiments in the 1970s, recognition memory for pictures is quite remarkable: humans can remember thousands of images at high accuracy after seeing each only once and only for a few seconds.Standing, L. (1973). "Learning 10,000 pictures". ''The Quarterly Journal of Experimental Psychology'', 25(2), 207–222. Retrieved Jan 20 2020, from . Recognition memory can be subdivided into two component processes: recollection and familiarity, sometimes referred to as "remembering" and "knowing", respectively. Recollection is the retrieval of details associated with the previously experienced event ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research-based Design
The research-based design process is a research process proposed by Teemu Leinonen, inspired by several design theories. It is strongly oriented towards the building of prototypes and it emphasizes creative solutions, exploration of various ideas and design concepts, continuous testing and redesign of the design solutions. The method is firmly influenced by the Scandinavian participatory design approach. Therefore, most of the activities take place in a close dialogue with the community that is expected to use the tools or services designed. Phases The process can be divided into four major phases, although they all happen concurrently and side by side. At different times of the research, researchers are asked to put more effort into different phases. The continuous iteration, however, asks researchers to keep all the phases alive all the time: contextual inquiry, participatory design, product design, prototype as hypothesis. Contextual inquiry Contextual inquiry refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
