Reinforcement refers to consequences that increase the likelihood of a person’s future behavior, typically in the presence of a particular antecedent stimulus.
Reinforcement occurs when a consequence follows a behavior and increases the probability that this behavior will be repeated under similar conditions.
The core idea is that behavior is shaped by its outcomes—actions that lead to satisfying results are more likely to recur, while those that do not are less likely to do so.
Punishment is the inverse to reinforcement, referring to any behavior that decreases the likelihood that a response will occur.
Punishment does not need to involve any type of pain, fear, or physical actions; even a brief spoken expression of disapproval is a type of punishment.
Consequences that lead to appetitive behavior such as subjective desire and pleasure function as rewards or positive reinforcement.
Negative reinforcement, which involves taking away an undesirable stimulus.
Reinforcement is an important component of operant conditioning and behavior modification.
Reinforcement concept has been applied in a variety of practical areas, including parenting, coaching, therapy, self-help, education, and management.
Behavioral reinforcement is a key concept in psychology that describes how consequences influence the likelihood of a behavior being repeated.
Behavioral reinforcement Is central to behavioral psychology, particularly the theory of operant conditioning.
Positive reinforcement refers to something desirable after a behavior to increase its frequency.
Negative reinforcement removes something unpleasant after a behavior to increase its frequency.
How often reinforcement is provided affects behavior:
Continuous reinforcement is when every instance of the behavior is reinforced.
Intermittent reinforcement is when only some instances are reinforced, which can be in a Fixed ratio-After a set number of responses Variable ratio-After an unpredictable number of responses Fixed interval-After a set time period Variable interval-After unpredictable time periods
Variable reinforcement ratio schedules typically produce the most persistent behaviors, explaining why gambling is so addictive.
Behavioral reinforcement is applied in many situations: Education and classroom management Parenting and child development Animal training Organizational behavior and workplace productivity Clinical therapy for behavior modification
Positive behavioral reinforcement actions are those that add a factor, be it pleasant or unpleasant, to the environment, whereas negative actions are those that remove or withhold from the environment a factor of either type.
Reinforcement refers only to reward-based conditioning; the introduction of unpleasant factors and the removal or withholding of pleasant factors are instead referred to as punishment.
Punishment term when used in its strict sense thus stands in contradistinction to reinforcement.
Positive reinforcement refers to the addition of a pleasant factor.
Positive punishment refers to the addition of an unpleasant factor.
Negative reinforcement refers to the removal or withholding of an unpleasant factor.
Negative punishment refers to the removal or withholding of a pleasant factor.
The sole criterion that determines if a stimulus is reinforcing is the change in probability of a behavior after administration of that potential reinforcer.
Reinforcement is the central concept and procedure in special education, applied behavior analysis, and the analysis of behavior and is a core concept in some medical and psychopharmacology particularly for addiction, dependence, and compulsion.
Positive reinforcement results in lasting behavioral modification, whereas punishment changes behavior only temporarily and has many detrimental side-effects.
Some studies have shown that positive reinforcement and punishment are equally effective in modifying behavior.
Positive reinforcement occurs when a positive stimulus is presented in response to a behavior, which increases the likelihood of that behavior in the future: it is a successful technique used by leaders to motivate and attain desired behaviors from subordinates.
Reinforcement is a basic term in operant conditioning.
Positive reinforcement occurs when a desirable event or stimulus is presented as a consequence of a behavior and the chance that this behavior will manifest in similar environments increases.
Negative reinforcement increases the rate of a behavior that avoids or escapes an aversive situation or stimulus.
That is, something unpleasant is already happening, and the behavior helps the person avoid or escape the unpleasantness.
In negative reinforcement, the focus is on the removal of an unpleasant situation or stimulus.
The success of that avoidant or escapist behavior in removing the unpleasant situation or stimulus reinforces the behavior.
Doing something unpleasant to people to prevent or remove a behavior from happening again is punishment, not negative reinforcement.
The main difference is that reinforcement always increases the likelihood of a behavior whereas punishment decreases it .
Extinction occurs when a given behavior is ignored, that is followed up with no consequence.
Behaviors disappear over time when they continuously receive no reinforcement.
During a deliberate extinction, the targeted behavior spikes first producing the expected, previously reinforced effects, and then declines over time.
Reinforcers serve to increase behaviors whereas punishers serve to decrease behaviors.
Positive reinforcers are stimuli that the subject will work to attain, and negative reinforcers are stimuli that the subject will work to be rid of or to end.
Some reinforcement can include both positive and negative features.
Reinforcement in the business world is essential in driving productivity.
Employees are constantly motivated by the ability to receive a positive stimulus, such as a promotion or a bonus.
Employees are also driven by negative reinforcement, such as by eliminating unpleasant tasks.
A primary reinforcer, sometimes called an unconditioned reinforcer, is a stimulus that does not require pairing with a different stimulus in order to function as a reinforcer: primary reinforcers include food, water, and sex.
Some primary reinforcers, such as certain drugs, may mimic the effects of other primary reinforcers.
Primary reinforcers are fairly stable through life and across individuals, the reinforcing value of different primary reinforcers varies due to multiple factors such as genetics, and experience.
A secondary reinforcer, (conditioned reinforcer), is a stimulus or situation that has acquired its function as a reinforcer after pairing with a stimulus that functions as a reinforcer.
This stimulus may be a primary reinforcer or another conditioned reinforcer.
A generalized reinforcer is a conditioned reinforcer that has obtained the reinforcing function by pairing with many other reinforcers and functions as a reinforcer under a wide-variety of motivating operations.
Reinforcement hierarchy is a list of actions, rank-ordering the most desirable to least desirable consequences that may serve as a reinforcer.
Behavior is not always reinforced every time it is emitted, and the pattern of reinforcement strongly affects how fast an operant response is learned, what its rate is at any given time, and how long it continues when reinforcement ceases.
The simplest rules controlling reinforcement are continuous reinforcement, where every response is reinforced, and extinction, where no response is reinforced.
More complex schedules of reinforcement specify the rules that determine how and when a response will be followed by a reinforcer.
Fixed interval (FI) – reinforced after n amount of time.
Differential reinforcement of incompatible behavior (DRI) is used to reduce a frequent behavior without punishing it by reinforcing an incompatible response.
Differential reinforcement of low response rate (DRL) is used to encourage low rates of responding.
It is like an interval schedule, except that premature responses reset the time required between behavior.
Differential reinforcement of high rate (DRH) is used to increase high rates of responding.
Ratio schedules produce higher rates of responding than interval schedules, when the rates of reinforcement are otherwise similar.
Variable schedules produce higher rates and greater resistance to extinction than most fixed schedules.
The variable ratio schedule produces both the highest rate of responding and the greatest resistance to extinction-the behavior of gamblers at slot machines.
Fixed schedules produce post-reinforcement pauses (PRP), where responses will briefly cease immediately following reinforcement, though the pause is a function of the upcoming response requirement rather than the prior reinforcement.
Compound schedules combine two or more different simple schedules in some way using the same reinforcer for the same behavior.
Reinforcement is essential in education, therapy, animal training, and management.
Reinforcement is systematically used to increase adaptive behaviors and decrease maladaptive ones.
Behavior analysts manipulate reinforcement schedules to promote consistent and sustainable learning.
Superimposed schedules of reinforcement can create the three classic conflict situations (approach–approach conflict, approach–avoidance conflict, and avoidance–avoidance conflict).
Shaping is the reinforcement of successive approximations to a desired instrumental response.
Chaining involves linking discrete behaviors together in a series, such that the consequence of each behavior is both the reinforcement for the previous behavior, and the antecedent stimulus for the next behavior.
Ways to teach chaining include: forward chaining, starting from the first behavior in the chain: backwards chaining, starting from the last behavior and: total task chaining, teaching each behavior in the chain simultaneously.
People’s morning routines are a typical chain, with a series of behaviors-showering, drying off, getting dressed occurring in sequence as a well learned habit.
Challenging behaviors seen in individuals with autism and other related disabilities have successfully managed and maintained in studies using a scheduled of chained reinforcements.
Positive and negative reinforcement play central roles in the development and maintenance of addiction and drug dependence.
An addictive drug is intrinsically rewarding; that is, it functions as a primary positive reinforcer of drug use.
The brain’s reward system assigns it incentive salience so as an addiction develops, deprivation of the drug leads to craving.
Stimuli associated with drug use –the sight of a syringe, and the location of use become associated with the intense reinforcement induced by the drug.
Previously neutral stimuli can acquire several properties and can induce craving, and they can become conditioned positive reinforcers of continued use.
In drug dependent individuals, negative reinforcement occurs when a drug is self-administered in order to alleviate the symptoms of physical dependence and/or psychological dependence that arise during the state of drug withdrawal.
Animal training provides one of the clearest and most convincing examples of operant control.
Child behavior – parent management training
Providing positive reinforcement for appropriate child behaviors is a major focus of parent management training.
Parents reward appropriate behavior through social rewards-praise, smiles, and hugs, as well as concrete rewards as part of an incentive system created collaboratively with the child.
A variable ratio schedule yields reinforcement after the emission of an unpredictable number of responses.
This schedule typically generates rapid, persistent responding.
Slot machines pay off on a variable ratio schedule, and they produce just this sort of persistent lever-pulling behavior in gamblers.
Because the machines are programmed to pay out less money than they take in, the persistent slot-machine user invariably loses in the long run.
Slots-machines, and thus variable ratio reinforcement, have often been blamed as a factor underlying gambling addiction.
Praise has been viewed as a means of positive reinforcement, wherein an observed behavior is made more likely to occur by contingently praising said behavior.
Hundreds of studies have demonstrated the effectiveness of praise in promoting positive behaviors: promoting improved behavior and academic performance, but also in work performance.
Praise has also been demonstrated to reinforce positive behaviors in non-praised adjacent individuals through vicarious reinforcement.
The strategic use of praise is recognized as an evidence-based practice in both classroom management and parenting training interventions, though praise is often subsumed in intervention research into a larger category of positive reinforcement, which includes strategies such as strategic attention and behavioral rewards.
Traumatic bonding occurs as the result of ongoing cycles of abuse in which the intermittent reinforcement of reward and punishment creates powerful emotional bonds that are resistant to change.
The necessary conditions for traumatic bonding are that one person must dominate the other and that the level of abuse chronically spikes and then subsides.
The relationship is characterized by periods of permissive, compassionate, and even affectionate behavior from the dominant person, punctuated by intermittent episodes of intense abuse.
To maintain dominance, the victimizer manipulates the behavior of the victim and limits the victim’s options so as to perpetuate the power imbalance.
Any threat to the balance of dominance and submission may be met with an escalating cycle of punishment ranging from seething intimidation to intensely violent outbursts.
The victimizer also isolates the victim from other sources of support, which reduces the likelihood of detection and intervention, impairs the victim’s ability to receive countervailing self-referent feedback, and strengthens the sense of unilateral dependency.
This impairment of the victim’s capacity for accurate self-appraisal, leading to a sense of personal inadequacy and a subordinate sense of dependence upon the dominating person.
Victims also may encounter a variety of unpleasant social and legal consequences of their emotional and behavioral affiliation with someone who perpetrated aggressive acts, even if they themselves were the recipients of the aggression.
Most video games are designed around some type of compulsion loop, adding a type of positive reinforcement through a variable rate schedule to keep the player playing the game, though this can also lead to video game addiction.
