Dishabituation
Dishabituation (or ''dehabituation'') is a form of recovered or restored behavioral response wherein the reaction towards a known stimulus is enhanced, as opposed to habituation. Initially, it was proposed as an explanation to increased response for a habituated behavior by introducing an external stimulus; however, upon further analysis, some have suggested that a proper analysis of dishabituation should be taken into consideration only when the response is increased by implying the original stimulus. Based on studies conducted over habituation's dual-process theory which attributed towards dishabituation, it is also determined that the latter was independent of any behavioral sensitization. An example of dishabituation is the response of a receptionist in a scenario where a delivery truck arrives at 9:00AM every morning. The first few times it arrives it is noticed by the receptionist, and after weeks, the receptionist does not respond as strongly. One day the truck does not arri ...

Habituation
Habituation is a form of non-associative learning in which an innate (non-reinforced) response to a stimulus decreases after repeated or prolonged presentations of that stimulus. Responses that habituate include those that involve the intact organism (e.g., full-body startle response) or those that involve only components of the organism (e.g., habituation of neurotransmitter release from ''in vitro'' Aplysia sensory neurons). The broad ubiquity of habituation across all biologic phyla has resulted in it being called "the simplest, most universal form of learning...as fundamental a characteristic of life as DNA." Functionally-speaking, by diminishing the response to an inconsequential stimulus, habituation is thought to free-up cognitive resources to other stimuli that are associated with biologically important events (i.e., punishment/reward). For example, organisms may habituate to repeated sudden loud noises when they learn these have no consequences. A progressive decline of a ...

Aplysia Gill And Siphon Withdrawal Reflex
The ''Aplysia'' gill and siphon withdrawal reflex (GSWR) is an involuntary, defensive reflex of the sea hare ''Aplysia californica'', a large shell-less sea snail or sea slug. This reflex causes the sea hare's delicate siphon and gill to be retracted when the animal is disturbed.Carew, T. J. (2000). Behavioral Neurobiology: The Cellular Organization of Natural Behavior. Sinauer Associates, Inc. ''Aplysia californica'' is used in neuroscience research for studies of the cellular basis of behavior including: habituation, dishabituation, and sensitization, because of the simplicity and relatively large size of the underlying neural circuitry. Eric Kandel, recipient of the Nobel Prize in Physiology or Medicine in 2000 for his work with ''Aplysia californica'', was involved in pioneering research into this reflex in the 1960s and 1970s. Nonassociative learning Nonassociative learning is a change of the behavior of an animal due to an experience from specific kinds of stimuli. In contr ...

Behavioral Concepts
Behavior (American English) or behaviour (British English) is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary. Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector. Models Biology Although disagreement exists as to how to precisely define behavior in a biological context, one common interpretation based on a meta-analysis of scientific literature states that "behavior is the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to internal and/or external stim ...

Stanford Medicine
Stanford University School of Medicine is the medical school of Stanford University and is located in Stanford, California. It traces its roots to the Medical Department of the University of the Pacific, founded in San Francisco in 1858. This medical institution, then called Cooper Medical College, was acquired by Stanford in 1908. The medical school moved to the Stanford campus near Palo Alto, California, in 1959. The School of Medicine, along with Stanford Health Care and Lucile Packard Children's Hospital, is part of Stanford Medicine. Stanford Health Care was ranked the fourth best hospital in California (behind UCLA Medical Center, Cedars-Sinai Medical Center, and UCSF Medical Center, respectively). History In 1855, Illinois physician Elias Samuel Cooper moved to San Francisco in the wake of the California Gold Rush. In cooperation with the University of the Pacific (also known as California Wesleyan College), Cooper established the Medical Department of the Unive ...

Reinforcement
In behavioral psychology, reinforcement is a consequence applied that will strengthen an organism's future behavior whenever that behavior is preceded by a specific antecedent stimulus. This strengthening effect may be measured as a higher frequency of behavior (e.g., pulling a lever more frequently), longer duration (e.g., pulling a lever for longer periods of time), greater magnitude (e.g., pulling a lever with greater force), or shorter latency (e.g., pulling a lever more quickly following the antecedent stimulus). The model of self-regulation has three main aspects of human behavior, which are self-awareness, self-reflection, and self-regulation. Reinforcements traditionally align with self-regulation. The behavior can be influenced by the consequence but behavior also needs antecedents. There are four types of reinforcement: positive reinforcement, negative reinforcement, extinction, and punishment. Positive reinforcement is the application of a positive reinforcer. Negati ...

Perceptual Learning
Perceptual learning is learning better perception skills such as differentiating two musical tones from one another or categorizations of spatial and temporal patterns relevant to real-world expertise. Examples of this may include reading, seeing relations among chess pieces, and knowing whether or not an X-ray image shows a tumor. Sensory modalities may include visual, auditory, tactile, olfactory, and taste. Perceptual learning forms important foundations of complex cognitive processes (i.e., language) and interacts with other kinds of learning to produce perceptual expertise. Underlying perceptual learning are changes in the neural circuitry. The ability for perceptual learning is retained throughout life. Category learning vs. perceptual learning It can be fairly easy to confuse category learning and perceptual learning. Category learning is "an assumed fixed, pre-established perceptual representation to describe the objects to be categorized." Category learning is built up ...

Operant Conditioning
Operant conditioning, also called instrumental conditioning, is a learning process where behaviors are modified through the association of stimuli with reinforcement or punishment. In it, operants—behaviors that affect one's environment—are conditioned to occur or not occur depending on the environmental consequences of the behavior. Operant conditioning originated in the work of Edward Thorndike, whose law of effect theorised that behaviors arise as a result of whether their consequences are satisfying or discomforting. In the 20th century, operant conditioning was studied by behaviorist psychologists, who believed that much, if not all, of mind and behaviour can be explained as a result of envirionmental conditioning. Reinforcements are environmental stimuli that increase behaviors, whereas punishments are stimuli that decrease behaviors. Both kinds of stimuli can be further categorised into positive and negative stimuli, which respectively involve the addition or removal o ...

Adaptive Behaviors
Adaptive behavior is behavior that enables a person (usually used in the context of children) to cope in their environment with greatest success and least conflict with others. This is a term used in the areas of psychology and special education. Adaptive behavior relates to everyday skills or tasks that the "average" person is able to complete, similar to the term life skills. Nonconstructive or disruptive social or personal behaviors can sometimes be used to achieve a constructive outcome. For example, a constant repetitive action could be re-focused on something that creates or builds something. In other words, the behavior can be adapted to something else. In contrast, maladaptive behavior is a type of behavior that is often used to reduce one's anxiety, but the result is dysfunctional and non-productive. For example, avoiding situations because you have unrealistic fears may initially reduce your anxiety, but it is non-productive in alleviating the actual problem in the lo ...

Mind-wandering
Mind-wandering is a broad term with no currently universal definition. According to McMillan, Kaufmann and Singer (2013) mind-wandering consists of 3 different subtypes: positive constructive daydreaming, guilty fear of failure, and poor attentional control. Whereas Smallwood and Schooler (2015) suggest that mind-wandering consists of thoughts that are task-unrelated and stimulus-independent. In general, a folk explanation of mind-wandering could be described as the experience of thoughts not remaining on a single topic for a long period of time, particularly when people are engaged in an attention-demanding task. One context in which mind-wandering often occurs is driving. This is because driving under optimal conditions becomes an almost automatic activity that can require minimal use of the task positive network, the brain network that is active when one is engaged in an attention-demanding activity. In situations where vigilance is low, people do not remember what happened in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arousal
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and readiness to respond. Arousal is mediated by several neural systems. Wakefulness is regulated by the ARAS, which is composed of projections from five major neurotransmitter systems that originate in the brainstem and form connections extending throughout the cortex; activity within the ARAS is regulated by neurons that release the neurotransmitters acetylcholine, norepinephrine, dopamine, histamine, and serotonin. Activation of these neurons produces an increase in cortical activity and subsequently alertness. Arousal is important in regulating consciousness, attention, alertn ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...
