The matching law is a principle that can be used to influence human behaviour by manipulating reinforcement schedules. It states that the behaviour that receives the most reinforcement will be the one most frequently chosen. In other words, if there are two response options and response option one provides two times the rate of reinforcement provided by option two, then there will be two times the rate of response on option one as opposed to option two. This law is important because it has generated a great deal of research that has widened our understanding of operant control. It has also helped behaviour analysts understand some complex human behaviours, especially the behaviour of children in certain conflict situations. The matching law can be used to choose the schedule that leads to the most desired behaviour.

Humans are complex and their decisions are influenced by multiple factors
Humans are complex, and their decisions are influenced by multiple factors. The Matching Law, a principle of Applied Behaviour Analysis (ABA), offers a quantitative relationship between the relative rates of response and reinforcement in concurrent schedules. It suggests that behaviour is directly proportional to the reinforcement available, and the behaviour with the highest reinforcement will be chosen most frequently. However, humans are not always driven solely by reinforcement, and their decisions are often influenced by a range of additional variables.
The Matching Law has been applied in clinical settings to understand how naturally occurring events affect socially important behaviours, including those of children with developmental disabilities. It provides a framework for understanding choice as the distribution of behaviour to reinforcement alternatives. For example, if a child with developmental disabilities exhibits problem behaviours (B1) and appropriate behaviours (B2), the relative rates of these behaviours should "match" the relative reinforcement associated with each response. By manipulating the rates of reinforcement, clinicians can influence the likelihood of a particular behaviour occurring.
While the Matching Law offers a useful tool for understanding and influencing behaviour, it has limitations when applied to human behaviour due to the complexity of human decision-making. Humans may not always choose the behaviour with the highest reinforcement, as their choices are influenced by a range of factors beyond simple reinforcement. Individual preferences, values, beliefs, and experiences can all impact decision-making, and these factors may not be easily observable or quantifiable. For example, an individual may choose an apple over a cookie not just because of the reinforcement associated with eating healthy, but also because of personal preferences, health concerns, or cultural influences.
The deviations from matching observed in human behaviour include undermatching, overmatching, and bias. Undermatching can occur when individuals switch too often between response options, potentially influenced by reinforcers that occur immediately after a switch. Overmatching refers to a stronger preference for one response over another, beyond what the law predicts. Bias reflects an individual's tendency to prefer one response over another, which may be influenced by factors beyond reinforcement rates. These deviations highlight the complex nature of human decision-making and the influence of factors beyond those considered by the Matching Law.
In conclusion, while the Matching Law provides a valuable framework for understanding and influencing behaviour, it is important to recognize that humans are complex, and their decisions are influenced by multiple factors beyond reinforcement rates. The deviations from matching observed in human behaviour highlight the need to consider individual differences and contextual variables when applying behavioural principles in real-life situations.

The Matching Law can be used to understand complex human behaviours, especially in children
The Matching Law is a behavioural principle that can be used to understand complex human behaviours, especially in children. It is a quantitative relationship between the relative rates of response and the relative rates of reinforcement in concurrent schedules of reinforcement. In other words, the Matching Law states that the rate of response is proportional to the rate of reinforcement for any task. This law has been observed in experiments involving human participants, although there have also been significant deviations.
The Matching Law can be applied to gain a better understanding of how naturally occurring events affect socially important behaviours. For example, in the context of children with developmental disabilities, researchers have found that children distribute either appropriate or inappropriate behaviours as a function of relative rates of reinforcement. This means that the relative rates of problem and appropriate behaviour should "match" the relative amount of reinforcement associated with each response class. By understanding the Matching Law, professionals can develop effective interventions for their clients.
The Matching Law also has implications for choice situations, which arise when concurrent schedules of reinforcement are available in the environment. It challenges the idea that choice is an unpredictable outcome of free will, suggesting instead that choice is simply behaviour set into the context of other behaviour. According to the Matching Law, when given two response alternatives, an individual will choose the option that provides the highest rate of reinforcement. This can be influenced by various factors such as the reinforcement rate, the quality of the reinforcer, and the reinforcement magnitude.
In addition, the Matching Law can inform the training process. It suggests that it is important to provide conditions in which making the "right choice" is easier than the alternative. This may involve manipulating the environment so that the "right choices" require little effort and receive a high rate of immediate reinforcement. For example, when potty training a puppy, it is more efficient to keep the puppy confined or closely supervised, rewarding it for pottying outside.
Overall, the Matching Law provides a framework for understanding complex human behaviours, particularly in children, by highlighting the relationship between response rates and reinforcement rates. By applying this law, professionals can gain insights into human behaviour and develop effective interventions.

Humans and animals maximise reinforcement in three ways: molecular maximising, molar maximising, and melioration
The matching law is a behavioural principle that can be applied to understand and influence human behaviour. It states that behaviour is directly proportional to the reinforcement available for it. In other words, humans tend to choose the behaviour that achieves the highest amount of reinforcement.
Melioration, which literally means "to make better", involves organisms responding in a way that improves the local rates of reinforcement for response alternatives. In other words, behaviour keeps shifting towards the better of two alternatives until their ratios are equal. This is also known as ""suboptimal choice", where organisms forfeit a higher overall reinforcement rate in favour of a lower rate. For example, in an experiment with pigeons, the birds allocated more time to a locally richer alternative even when doing so resulted in a suboptimal choice.
The matching law has been applied in clinical settings to gain a better understanding of how naturally occurring events affect socially important behaviours. It has also been used to understand complex human behaviours, especially the behaviour of children in certain conflict situations.

The Matching Law can be used to influence behaviour by manipulating reinforcement schedules
The Matching Law is a behavioural principle that can be used to influence behaviour by manipulating reinforcement schedules. It is based on the idea that behaviour occurs in direct proportion to the reinforcement available for each behaviour. In other words, when two or more concurrent schedules exist, individuals will show a preference for the behaviour that achieves the highest amount of reinforcement.
The Matching Law can be applied by increasing the magnitude of reinforcement for a desired behaviour, thereby increasing the likelihood of that behaviour occurring over others. This technique is particularly useful when one schedule of reinforcement is outside of one's control or when one wants to avoid the negative effects of extinction. For example, in Applied Behaviour Analysis (ABA), professionals may adjust the reinforcement magnitude to reinforce target behaviours more strongly. This can be achieved by providing a more preferred or higher magnitude reinforcer for adaptive behaviours, while offering a less preferred or lower magnitude reinforcer for behaviours targeted for reduction.
The Matching Law has been used to understand complex human behaviours, especially the behaviour of children in certain conflict situations. For instance, researchers have found that children with developmental disabilities distribute either appropriate or inappropriate behaviours based on the relative rates of reinforcement. By manipulating the reinforcement schedules, professionals can increase the occurrence of desired behaviours and reduce unwanted behaviours.
The Matching Law also has applications in other fields, such as economics and policymaking. By understanding the relationship between different behaviours and their associated reinforcers, economists and policymakers can design effective incentive structures, influence consumer behaviour, and shape decision-making. Additionally, the Matching Law can be used to study the effects of different reinforcers and their magnitudes, providing insights into substance abuse, addiction, and related behavioural patterns.
In summary, the Matching Law is a powerful tool that can be used to influence behaviour by manipulating reinforcement schedules. By increasing the reinforcement for desired behaviours, professionals can effectively guide individuals towards more positive and adaptive choices.

The Matching Law can be used to choose the schedule that leads to the most desired behaviour
The Matching Law is a behavioural principle that can be used to influence behaviour by manipulating reinforcement schedules. It was first formulated by R.J. Herrnstein in 1961, following an experiment with pigeons on concurrent variable interval schedules. In the experiment, pigeons were presented with two buttons, each of which led to varying rates of food reward. The pigeons tended to peck the button that yielded the greater food reward more often than the other button, and the ratio of their rates to the two buttons matched the ratio of their rates of reward.
The Matching Law states that behaviour occurs in direct proportion to the reinforcement available for each behaviour. When two or more concurrent schedules exist, preference is shown to the behaviour that achieves the highest amount of reinforcement. For example, if an individual receives twice as much reinforcement for behaviour 1 as for behaviour 2, they are likely to engage in behaviour 1 twice as much as behaviour 2.
By increasing the magnitude of reinforcement for a desired behaviour, one can increase the likelihood of that behaviour occurring over other behaviours. This technique is especially useful when one schedule of reinforcement is outside of one's control or when one wants to avoid the negative effects of extinction.
The Matching Law has been applied in clinical settings and populations to gain a better understanding of how naturally occurring events affect socially important behaviours. It has also been used to understand some complex human behaviours, especially the behaviour of children in certain conflict situations.

Frequently asked questions
The matching law is a behavioural principle that states that behaviour occurs in direct proportion to the reinforcement available for each behaviour.
The matching law can be applied to humans in a similar way to animals. Humans make choices based on the reinforcement rate, the quality of the reinforcer, the reinforcement magnitude, and whether there is a delay with the reinforcement.
The matching law can be used to train humans by manipulating concurrent schedules to influence behaviour. This can be done by increasing the magnitude of reinforcement for a desired behaviour, which will increase the likelihood of that behaviour occurring over other behaviours.
The matching law has historically been used as a quantitative measurement tool in the experimental analysis of behaviour. However, when applying the matching law in real-life situations, professionals often find that interventions that work in controlled, experimental settings are problematic or unacceptable in applied settings.
