Desensitization (psychology)
In psychology, desensitization is a treatment or process that diminishes emotional responsiveness to a negative, aversive or positive stimulus after repeated exposure to it. Desensitization also occurs when an emotional response is repeatedly evoked in situations in which the action tendency that is associated with the emotion proves irrelevant or unnecessary. The process of desensitization was developed by psychologist Mary Cover Jones, and is primarily used to assist individuals in unlearning phobias and anxieties. Joseph Wolpe (1958) developed a method of a hierarchal list of anxiety evoking stimuli in order of intensity, which allows individuals to undergo adaption. Although medication is available for individuals with anxiety, fear or phobias, empirical evidence supports desensitization with high rates of cure, particularly in clients with depression or schizophrenia. Steps The hierarchical list is constructed between client and therapist in rank ordered series of steps fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Extinction (psychology)
Extinction is a behavioral phenomenon observed in both operantly conditioned and classically conditioned behavior, which manifests itself by fading of non-reinforced conditioned response over time. When operant behavior that has been previously reinforced no longer produces reinforcing consequences the behavior gradually stops occurring.Miltenberger, R. (2012). ''Behavior modification, principles and procedures''. (5th ed., pp. 87-99). Wadsworth Publishing Company. In classical conditioning, when a conditioned stimulus is presented alone, so that it no longer predicts the coming of the unconditioned stimulus, conditioned responding gradually stops. For example, after Pavlov's dog was conditioned to salivate at the sound of a metronome, it eventually stopped salivating to the metronome after the metronome had been sounded repeatedly but no food came. Many anxiety disorders such as post traumatic stress disorder are believed to reflect, at least in part, a failure to extinguish c ...

Research On The Effects Of Violence In Mass Media
The studies of violence in mass media analyzes the degree of correlation between themes of violence in media sources (particularly violence in video games, television and films) with real-world aggression and violence over time. Many social scientists support the correlation. However, some scholars argue that media research has methodological problems and that findings are exaggerated. Other scholars have suggested that the correlation exists, but can be unconventional to what is mainly believed. Complaints about the possible deleterious effects of mass media appear throughout history; Plato was concerned about the effects of plays on youth. Various media/genres, including dime novels, comic books, jazz, rock and roll, role playing/computer games, television, films, internet (by computer or cell phone) and many others have attracted speculation that consumers of such media may become more aggressive, rebellious or immoral. This has led some scholars to conclude statements made by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entomophobia
Entomophobia sometimes known as Insectophobia is a specific phobia characterized by an excessive or unrealistic fear of one or more classes of insect, and classified as a phobia by the DSM-5. More specific cases includes arachnophobia (fear of spiders), katsaridaphobia (fear of cockroaches), melissophobia (fear of bees), myrmecophobia (fear of ants), and lepidopterophobia (fear of moths and butterflies). One book claims 6% of all US inhabitants have this phobia. Entomophobia may develop after the person has had a traumatic experience with the insect(s) in question. It may develop early or later in life and is quite common among animal phobias. Typically one has a fear of one specific type of insect, but in some cases this may encompass most, if not all other insects, and possibly other animals of the phylum Arthropoda. Entomophobia leads to behavioral changes: the person with entomophobia will avoid situations where they may encounter the specific type of insect. Cognitive behavio ...

Starting Gate
A starting gate also called a starting barrier or starting stalls is a machine used to ensure a fair start to in horse racing and dog racing. History Throughout the history of horse racing, there have been proposals as to how better to start a race. A commonly used starting system for horse races was devised in the mid nineteenth century by Admiral Rous, a steward of the Jockey Club and public handicapper. A starter, standing alongside the jockeys and horses, dropped his flag to signal the start. An assistant some 100 yards down the course raised a second flag to indicate false starts. An official starter might be well paid, but his duties were very demanding. Early in the twentieth century, he was supported by perhaps a single assistant who primed the spring-barrier, as well as the clerk of the course. In the present day there are many attendants to steady runners from super-structured barrier stalls. The first horse racing starting barriers were simple ropes or occasion ...

Race Horse
Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance is in the gambling associated with i ...

NMDA Receptor
The ''N''-methyl-D-aspartate receptor (also known as the NMDA receptor or NMDAR), is a glutamate receptor and ion channel found in neurons. The NMDA receptor is one of three types of ionotropic glutamate receptors, the other two being AMPA receptor, AMPA and kainate receptors. Depending on its subunit composition, its Ligand (biochemistry), ligands are glutamate and glycine (or D-Serine, D-serine). However, the binding of the ligands is typically not sufficient to open the channel as it may be blocked by Magnesium, Mg2+ ions which are only removed when the neuron is sufficiently depolarized. Thus, the channel acts as a “coincidence detector” and only once both of these conditions are met, the channel opens and it allows cation, positively charged ions (cations) to flow through the cell membrane. The NMDA receptor is thought to be very important for controlling synaptic plasticity and mediating learning and memory functions. The NMDA receptor is ionotropic, meaning it is a pr ...

Amygdala
The amygdala (; plural: amygdalae or amygdalas; also '; Latin from Greek, , ', 'almond', 'tonsil') is one of two almond-shaped clusters of nuclei located deep and medially within the temporal lobes of the brain's cerebrum in complex vertebrates, including humans. Shown to perform a primary role in the processing of memory, decision making, and emotional responses (including fear, anxiety, and aggression), the amygdalae are considered part of the limbic system. The term "amygdala" was first introduced by Karl Friedrich Burdach in 1822. Structure The regions described as amygdala nuclei encompass several structures of the cerebrum with distinct connectional and functional characteristics in humans and other animals. Among these nuclei are the basolateral complex, the cortical nucleus, the medial nucleus, the central nucleus, and the intercalated cell clusters. The basolateral complex can be further subdivided into the lateral, the basal, and the accessory basal nucle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prefrontal Cortex
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex. This brain region has been implicated in executive functions, such as planning, decision making, short-term memory, personality expression, moderating social behavior and controlling certain aspects of speech and language. Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, e ...

Expectancy Theory
Expectancy theory (or expectancy theory of motivation) proposes that an individual will behave or act in a certain way because they are motivated to select a specific behavior over others due to what they expect the result of that selected behavior will be. In essence, the motivation of the behavior selection is determined by the desirability of the outcome. However, at the core of the theory is the cognitive process of how an individual processes the different motivational elements. This is done before making the ultimate choice. The outcome is not the sole determining factor in making the decision of how to behave. Expectancy theory is about the mental processes regarding choice, or choosing. It explains the processes that an individual undergoes to make choices. In the study of organizational behavior, expectancy theory is a motivation theory first proposed by Victor Vroom of the Yale School of Management. Victor H. Vroom (1964) defines motivation as a process governing choic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
