Psychology Definition of RESPONSE DEPRIVATION: A method to identify reinforcers in operant conditioning, prior to demonstration of efficacy. Although operant and classical conditioning both involve behaviors controlled by environmental stimuli, they differ in nature. In operant conditioning, stimuli present when a behavior is rewarded or punished come to control that behavior. For example, a child may learn to open a box to get the sweets inside.
C. Pavlov's findings on the conditioned salivary response. D. Garcia and Koelling's findings on taste aversion in rats. A psychologist would be most likely to use ________ to determine whether nonverbal organisms can perceive different colors. A classical conditioning procedure describes the conditional relationship between an environmental stimulus (conditioned stimulus, CS) and the subsequent occurrence of an unconditionally reinforcing stimulus (unconditioned stimulus, UCS) that reliably elicits a recorded response (unconditioned response, UCR) (Pavlov, ).Cited by: 1.
In Experiment 1, we assessed the effects of the dopamine D 1 /D 2 receptor antagonist flupenthixol ( mg/kg i.p.) on Pavlovian incentive motivation and found that flupenthixol blocked the ability of a . Operant conditioning is based on the work of B. F. Skinner. Operant conditioning is a form of learning in which the motivation for a behavior happens after the behavior is demonstrated. An animal or a human receives a consequence after performing a specific behavior. The consequence is either a .

It has also been demonstrated that there is a direct relation between response effort and deprivation level. For example, Brackney, Cheung, Neisewander, and Sanabria () showed that “Motivation is a function of both incentive (deprivation) and response. Response cost may influence operant motivation as shown by the effects of motoric Cited by: To investigate effects of food deprivation on learned preferences for sweet solutions, we employed a conditioned flavor-calorie procedure using palatable sucrose or saccharin solutions as unconditioned stimuli (US) and tested intake of paired conditioned stimulus (CS) flavors under both deprived and free-fed by: The present study utilized a novel behavioral design to examine relative reward effects on a chain of operant behavior using auditory cues.
Incentive contrast is the most often examined effect and focuses on increases or decreases in behavioral performance after value upshifts (positive) or downshifts (negative) relative to another by: Drugs of abuse can influence the expression of this behavior, and nicotine in particular exhibits incentive amplifying effects.
Both conditioned approach behavior and drug abuse rely on. If palatability was a component of homeostatic control, reducing need-state should reduce palatability. However, this is not so, and if anything palatability exerts a stronger stimulatory effect on eating when sated, and over-consumption induced by palatability may contribute to by: experiments that separate the effects of drive from those of incentive-motivational (reinforcement linked) stimuli indicate that, while certain drives can raise the level of general activity and facilitate the occurrence of particular consummatory responses, drive facilitation of instrumental behavior results not from drive per se, but from an increase in the efficacy of incentive-motivational Cited by: In Experiment 2, the residual deprivation effect associated with a reduction in deprivation level occurred only when rats initially experienced the reinforcer at a high, as compared with a low.
This conditioned increase in acceptance, however, is a more variable response and is less resistant to extinction than is the conditioned preference response. These findings indicate that nutrient conditioning can have multiple effects on the reward value of the CS+ by: Acutely administered lorcaserin (–3 mg/kg, subcutaneous (SC)) dose dependently reduced feeding induced by h food deprivation or palatability.

The effects of three periods of prior food deprivation (either 0, 12, or h) on locomotor activity and c-Fos immunoreactivity were assessed in animals given no food, a small meal (g of sweetened 45mg pellets; BioServ, Frenchtown, NJ), or enough food to allow for unrestricted feeding (20g of the same pellets).Cited by: Generalization is the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses.

If the smell of food (the unconditioned stimulus) had been paired with the sound of a whistle (the conditioned stimulus), it would eventually come to evoke the conditioned response of hunger. However, if the unconditioned stimulus (the smell of food) was no longer paired with the conditioned stimulus (the whistle).
reflects the subjective palatability of the US (subject to "internal milieu" of organism, e.g. deprivation enhancing incentive value of US!), can be positive/negative (ex. thirsty from hot environment + hot water = worse incentive, NEGATIVE alliesthesia).
In three experiments, we assessed the effect of lesions aimed at the gustatory region of the insular cortex on instrumental conditioning in rats. In experiment 1, the lesion had no effect on the acquisition of either lever pressing or chain pulling in food-deprived rats whether these actions earned food pellets or a maltodextrin solution.
The lesion did, however, attenuate the impact of Cited by: The Otsuka Long-Evans Tokushima Fatty (OLETF) rat, an outbred strain of Long- Evans Tokushima Otsuka rat (LETO) that lacks CCK-1 receptor expression, Cited by: Statistical analysis of the data of Figure 2 B reveals only a main effect of deprivation (F (1,30) =P = ) on the palatability-related lick frequency measure, with neither a main effect of drug (F (1,30) =P = ), nor an interaction between these factors (F (1,30) =P = ).Cited by:.
What effect does stimulus variability have on the extinction of operant behaviors? if a response is learned in a variety of stimulus situations its harder to distinguish the behavior. ex: smoker smokes after meals, in bars, after sex, in vegas.
so its harder to distinguish smoking because theres many situations that would onset it. Amphetamine microinjection into the nucleus accumbens shell enhanced the ability of a Pavlovian reward cue to trigger increased instrumental performance for sucrose reward in a pure conditioned incentive paradigm.
Rats were first trained to press one of two levers to obtain sucrose pellets. They were separately conditioned to associate a Pavlovian cue (30 sec light) with free Cited by: Fig. 3 compares the effects of the dietary manipulations on the daily total number of seeking and taking reinforcers earned under both stimulus conditions.
Acute caloric deprivation significantly increased the daily total number of seeking reinforcers earned under both stimulus conditions, with the increase being about twice as large under the 1-s time-out by:
