Orienting Reflex
The orienting response (OR), also called ''orienting reflex'', is an organism's immediate response to a change in its environment, when that change is not sudden enough to elicit the startle reflex. The phenomenon was first described by Russian physiologist Ivan Sechenov in his 1863 book ''Reflexes of the Brain'', and the term ('ориентировочный рефлекс' in Russian) was coined by Ivan Pavlov, who also referred to it as the ''Shto takoye?'' (Что такое? or ''What is it?'') reflex. The orienting response is a reaction to novel or significant stimuli. In the 1950s the orienting response was studied systematically by the Russian scientist Evgeny Sokolov, who documented the phenomenon called "habituation", referring to a gradual "familiarity effect" and reduction of the orienting response with repeated stimulus presentations.Sokolov, E.N, Neuronal models and the orienting reflex, in ''The Central Nervous System and Behavior'', Mary A.B.

Startle Response
In animals, including humans, the startle response is a largely unconscious defensive response to sudden or threatening stimuli, such as sudden noise or sharp movement, and is associated with negative Affect (psychology), affect.Rammirez-Moreno, David. "A computational model for the modulation of the prepulse inhibition of the acoustic startle reflex". ''Biological Cybernetics'', 2012, p. 169 Usually the onset of the startle response is a startle reflex reaction. The startle reflex is a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and Fight-or-flight response, facilitates escape from sudden stimuli. It is found across many different species, throughout all stages of life. A variety of responses may occur depending on the affected individual's emotional state, body posture, preparation for execution of a motor task, or other activities. The startle response is implicated in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extrastriate Cortex
The extrastriate cortex is the region of the occipital cortex of the mammalian brain located next to the primary visual cortex. Primary visual cortex (V1) is also named striate cortex because of its striped appearance in the microscope. The extrastriate cortex encompasses multiple functional areas, including V3, V4, V5/MT, which is sensitive to motion,Guy A. Orban. Higher Order Visual Processing in Macaque Extrastriate Cortex. ''Physiol Rev'' January 1, 2008 88:(1) 59-89; or the extrastriate body area (EBA) used in the perception of human bodies. Anatomy In terms of Brodmann areas, the extrastriate cortex comprises Brodmann area 18 and Brodmann area 19, while the striate cortex comprises Brodmann area 17. In primates, the extrastriate cortex includes visual area V3, visual area V4, and visual area MT (sometimes called V5), while V1 corresponds to the striate cortex, and V2 to the prestriate cortex.

Neurophysiology
Neurophysiology is a branch of physiology and neuroscience that studies nervous system function rather than nervous system architecture. This area aids in the diagnosis and monitoring of neurological diseases. Historically, it has been dominated by electrophysiology—the electrical recording of neural activity ranging from the molar (the electroencephalogram, EEG) to the cellular (intracellular recording of the properties of single neurons), such as patch clamp, voltage clamp, extracellular single-unit recording and recording of local field potentials. However, since the neurone is an electrochemical machine, it is difficult to isolate electrical events from the metabolic and molecular processes that cause them. Thus, neurophysiologists currently utilise tools from chemistry (calcium imaging), physics (functional magnetic resonance imaging, Functional magnetic resonance imaging, fMRI), and molecular biology (site directed mutations) to examine brain activity. The word originates f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interest (emotion)
Interest is a feeling or emotion that causes attention to focus on an object, event, or process. In contemporary psychology of interest, the term is used as a general concept that may encompass other more specific psychological terms, such as curiosity and to a much lesser degree surprise. The emotion of interest does have its own facial expression, of which the most prominent component is having dilated pupils. Applications in computer assisted communication and B-C interface In 2016, an entirely new communication device and brain-computer interface was revealed, which required no visual fixation or eye movement at all, as with previous such devices. Instead, the device assesses more covert interest, that is by assessing other indicators than eye fixation, on a chosen letter on a virtual keyboard. Each letter has its own (background) circle that is micro-oscillating in brightness in different time transitions, where the determination of letter selection is based on the b ...

Attention
Attention is the behavioral and cognitive process of selectively concentrating on a discrete aspect of information, whether considered subjective or objective, while ignoring other perceivable information. William James (1890) wrote that "Attention is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence." Attention has also been described as the allocation of limited cognitive processing resources. Attention is manifested by an attentional bottleneck, in terms of the amount of data the brain can process each second; for example, in human vision, only less than 1% of the visual input data (at around one megabyte per second) can enter the bottleneck, leading to inattentional blindness. Attention remains a crucial area of investigation within education, psychology, neuroscience, cognitive neuroscience, and neuropsychology. ...

Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The process that follows connects a person's concepts and expectations (or knowledge), restorative and selective mechanisms (such as ...

Browsing
Browsing is a kind of orienting strategy. It is supposed to identify something of relevance for the browsing organism. When used about human beings it is a metaphor taken from the animal kingdom. It is used, for example, about people browsing open shelves in libraries, window shopping, or browsing databases or the Internet. In library and information science it is an important subject, both purely theoretically and as applied science aiming at designing interfaces which support browsing activities for the user. Definition Hjørland (2011b) provided the following definition: "Browsing is a quick examination of the relevance of a number of objects which may or may not lead to a closer examination or acquisition/selection of (some of) these objects. It is a kind of orienting strategy that is formed by our "theories", "expectations" and "subjectivity". Controversies As with any kind of human psychology, browsing can be understood in biological, behavioral, or cognitive terms on ...

Information Metabolism
Information metabolism, sometimes referred to as informational metabolism or energetic-informational metabolism, is a psychological theory of interaction between biological organisms and their environment, developed by Polish psychiatrist Antoni Kępiński. Overview Kępiński described his psychological theory in several books but the most detailed description is given in his 1974 book ''Melancholy'' (in Polish: "Melancholia"). In order to explain psychological phenomena encountered in humans, he borrowed many concepts from the field of cybernetics which gained popularity in Poland at that time, thanks to the works of Marian Mazur (the father of the Polish school of cybernetics). Kępiński starts with the consideration of most basic organisms and how they are different from inanimate matter. First of all, any organism may be treated as an autonomous but open system, separated from its environment by means of a boundary (skin or cell membrane). As an open system, it is en ...

Vicarious Traumatization
Vicarious trauma (VT) was a term invented by McCann and Pearlman that is used to describe how working with traumatized clients affects trauma therapists. Previously, the phenomenon was referred to as secondary traumatic stress coined by Dr. Charles Figley. The theory behind vicarious trauma is that the therapist has a profound world change and is permanently altered by the interaction of empathetic bonding with a client. This change is thought to have three conditional requirements: empathic engagement and exposure to graphic and traumatizing material, the therapist being exposed to human cruelty, and reenactment of trauma within the therapy process. This change can produce changes in a therapist’s sense of spirituality, worldview, and self-identity. Vicarious trauma is still a subject of debate by theorists, with some saying it is based on the concept of countertransference, burnout, and compassion fatigue. McCann and Pearlman argue, however, that there is probably a relationshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al Gore
Albert Arnold Gore Jr. (born March 31, 1948) is an American politician, businessman, and environmentalist who served as the 45th vice president of the United States from 1993 to 2001 under President Bill Clinton. Gore was the Democratic Party (United States), Democratic List of United States Democratic Party presidential tickets, nominee for the 2000 United States presidential election, 2000 presidential election, losing to George W.

The Assault On Reason
''The Assault on Reason'' is a 2007 book by Al Gore. In the book, the former U.S. Vice President heavily criticizes the George W. Bush administration for its actions in furthering the "assault on reason". He argues that there is a trend in U.S. politics toward ignoring facts and analysis when making policy decisions, calling the Congress, the judiciary, and the press complicit in the process. Gore's prescription is that the average citizen must be proactive in "restoring democracy". He expresses hopes that the medium of the Internet will supersede television and what he argues is its inherent bias, creating a "marketplace of ideas" that has not been present since the replacement of the printed word with mass media. The book ranked number one on the ''New York Times'' Best Seller list for hardcover nonfiction during the first four weeks of its release, and was on the top-35 list for fifteen weeks.

Eye Movement Desensitization And Reprocessing
Eye movement desensitization and reprocessing (EMDR) is a form of psychotherapy developed by Francine Shapiro in the 1980s that was originally designed to alleviate the distress associated with traumatic memories such as post-traumatic stress disorder (PTSD). In EMDR, the person being treated recalls distressing experiences whilst doing bilateral stimulation, such as side-to-side eye movement or physical stimulation, such as tapping either side of the body. The 2013 World Health Organization (WHO) practice guideline states that EMDR "is based on the idea that negative thoughts, feelings, and behaviors are the result of unprocessed memories. The treatment involves standardized procedures that include focusing simultaneously on spontaneous associations of traumatic images, thoughts, emotions and bodily sensations and bilateral stimulation that is most commonly in the form of repeated eye movements." EMDR is included in several evidence-based guidelines for the treatment of PTSD, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
