CR includes a heightened pain sensitivity, and decreased body temperature, and might cause discomfort, thus motivating the drug user to continue usage of the drug. This is one of several ways classical conditioning might be a factor in drug addiction and dependence. [2] In a classic experiment, Shepard Siegel conditioned rats with morphine ...
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
[3] The clinical utility of cue reactivity is based on the conceptualization that drug cues elicit craving which is a critical factor in the maintenance and relapse to drug use. [5] [6] Additionally, cue reactivity allows for the development of testable hypotheses grounded in established theories of human behavior. [4]
Latent inhibition (LI) is a technical term in classical conditioning, where a familiar stimulus takes longer to acquire meaning (as a signal or conditioned stimulus) than a new stimulus. [1] The term originated with Lubow and Moore in 1973. [2]
Spontaneous recovery is associated with the learning process called classical conditioning, in which an organism learns to associate a neutral stimulus with a stimulus which produces an unconditioned response. As a result, the previously neutral stimulus comes to produce its own response, which is usually similar to that produced by the ...
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
The higher the frequency with which a test animal emits the operant behavior, the more rewarding (and addictive), the test substance is considered. Self-administration of addictive drugs has been studied using humans, [1] non-human primates, [2] mice, [3] invertebrates such as ants, and, most commonly, rats.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption ...
