The Law of Effect, also known as Thorndike's Law, is a principle of psychology developed by American psychologist Edward Thorndike in the early 20th century, specifically in 1905, and published in 1911. The law states that behaviours that lead to satisfying outcomes are likely to be repeated, while behaviours that lead to undesired outcomes are less likely to recur. Thorndike's law was a precursor to B.F. Skinner's operant conditioning and had a significant influence on the development of behaviourism.

The law of effect was developed by Edward Thorndike in 1898
The law of effect, also known as Thorndike's law, is a psychology principle developed by American psychologist Edward Thorndike in 1898. It is a theory of behavioural conditioning that states that responses that produce a satisfying effect in a particular situation are likely to recur in similar situations, while responses that produce a discomforting effect are less likely to occur again.
Thorndike's law of effect was influenced by his desire to build a newer theory of learning that could be more widely used than classical conditioning, which had risen to prominence with Ivan Pavlov in 1897. Thorndike believed that the learner could take an active role in their conditioning, and his law of effect states that the learner will want to repeat behaviours that are followed by something positive and will not want to repeat behaviours that are followed by something negative.
Thorndike's famous experiments with animals, typically cats, illustrated his theory. In these experiments, a cat was placed in a box that could be opened if the cat pressed a lever or pulled a loop. The cat was rewarded with food following each lever press, and over successive trials, the cat learned to press the lever more quickly to obtain its reward. This demonstrated that the correct response was reinforced by its consequence, and the law of effect holds that once the stimulus and response are associated, the response is likely to occur without the stimulus being present.
The law of effect was published by Thorndike in 1905 or 1911 and modified by him in 1932. It influenced the development of behaviourism during the first half of the 20th century, with B.F. Skinner building on Thorndike's work to formalize the process of operant conditioning.

It was first published in his 1911 book, 'Animal Intelligence'
The Law of Effect, also known as Thorndike's Law, was developed by the American psychologist Edward Thorndike in the early 20th century. Thorndike's work was heavily influenced by his desire to build a theory of learning that could be more widely used than classical conditioning, which was widely accepted in the psychological community at the time.
Thorndike's law of effect, in animal behaviour and conditioning, argues that the probability of a particular stimulus repeatedly eliciting a particular learned response depends on the perceived consequences of the response. In other words, if a behaviour is followed by a positive consequence, we are more likely to repeat that behaviour, and if it is followed by a negative consequence, we are less likely to repeat it.
Thorndike's law was first published in his 1911 book, 'Animal Intelligence'. The law refuted the ideas presented in George Romanes' book of the same name, which stated that animals, like humans, think things through when dealing with a new environment or situation. Thorndike disagreed with this, hypothesizing that animals must physically interact with their physical environment through trial and error until a successful result is obtained.
Thorndike's experiments with animals, typically cats, illustrated his hypothesis. In one such experiment, Thorndike placed a cat in a puzzle box with a lever on one side. The cat could only escape by pressing the lever, which would result in a piece of meat being placed outside the box as a reward. Over time, the cat would press the lever more quickly, as it was rewarded with both its freedom and food following each lever press.

The law of effect is a precursor to B.F. Skinner's operant conditioning
The Law of Effect, also known as Thorndike's Law, is a psychology principle advanced by Edward Thorndike in 1898. It states that responses that produce a satisfying effect in a particular situation are likely to recur in similar situations, while responses that produce a discomforting effect are less likely to occur again. This idea is similar to evolutionary theory, where a certain trait that provides an advantage will persist.
Thorndike's experiments with animals, typically cats, demonstrated this principle. He would place a cat in a puzzle box with a small lever on one side, which could be opened if the cat pressed the lever. Initially, the cat would respond ineffectively, but eventually, it would escape by pressing or pulling the lever by accident. Over successive trials, the cat would take less and less time to escape, as the correct response was reinforced by the consequence of release from the box.
Thorndike's Law of Effect is considered a precursor to B.F. Skinner's operant conditioning. Skinner, an American psychologist, built on Thorndike's work and formalised the process of operant conditioning, which he understood to be the basis of human behaviour. Operant conditioning holds that behaviours that lead to satisfying outcomes are likely to be repeated, while behaviours that lead to undesired outcomes are less likely to recur.
The Law of Effect is important in understanding how people learn and has influenced the development of behaviourism. It emphasises the active role of the learner in their conditioning, as they can modify their behaviour based on the consequences of their actions. This idea has been applied in various fields, including education, where it has informed teaching methods and strategies for promoting desired behaviours and outcomes.
Overall, the Law of Effect, as proposed by Thorndike, laid the foundation for a deeper understanding of human behaviour and learning, which was further developed and expanded upon by B.F. Skinner's operant conditioning theory.

It states that behaviours with satisfying outcomes are likely to be repeated
The Law of Effect, also known as Thorndike's Law, is a principle of psychology developed by American psychologist Edward Thorndike in the early 20th century, specifically in 1905, and published in 1911. It is a theory of behavioural conditioning that states that behaviours with satisfying outcomes are likely to be repeated.
Thorndike's experiments with animals, typically cats, informed his formulation of the Law of Effect. In one such experiment, Thorndike placed a cat in a puzzle box with a lever on one side. The cat could only escape the box by pressing the lever, which would result in a piece of meat being placed outside the box as a reward. Over successive trials, the cat learned to press the lever more quickly to obtain the reward. This observation led Thorndike to conclude that behaviours with positive outcomes are more likely to be repeated.
In modern terminology, the correct response (pressing the lever) was reinforced by its consequence (release from the box and receipt of food). This is an example of operant conditioning, where the stimulus-response connection is strengthened when followed by a satisfying result. The Law of Effect states that responses that produce a satisfying effect in a particular situation will become more likely to occur again in that situation, while responses that produce a discomforting effect will become less likely to occur again.
Thorndike's Law of Effect has had a significant influence on the development of behaviourism, with psychologist B.F. Skinner building upon it to formalize the process of operant conditioning. The Law of Effect is, therefore, an important precursor to our understanding of human behaviour and learning.
Overall, the Law of Effect provides a framework for understanding how behaviours with satisfying outcomes are likely to be repeated, with implications for various fields, including psychology, education, and behavioural science.

The law of effect is also referred to as Thorndike's law
The Law of Effect, also known as Thorndike's Law, is a psychology principle advanced by Edward Thorndike in 1898 on the matter of behavioral conditioning. It states that responses that produce a satisfying effect in a particular situation are likely to recur in similar situations, while responses that produce a discomforting effect are less likely to occur again. The law of effect is the belief that a pleasing after-effect strengthens the action that produced it.
Thorndike's Law of Effect is based on the idea that animals, including humans, understand their physical environment through physical interaction and trial and error. This refutes the ideas presented in George Romanes' book 'Animal Intelligence', which stated that animals think things through when dealing with new environments or situations. Thorndike's experiments with cats in puzzle boxes demonstrated that the cats learned to escape by interacting with their environment. With each successful trial, the cats took less time to escape, reinforcing the correct response through the consequence of release from the box.
The Law of Effect was further developed by Thorndike in his book 'Animal Intelligence', published in 1911. The law had two parts: the first stated that responses accompanied by satisfaction would be more firmly connected with the situation and were likely to recur, while the second part stated that responses accompanied by discomfort would weaken the connection to the situation and were less likely to occur again. Thorndike modified his law in 1932, concluding that positive outcomes or rewards strengthened the association between the situation and response, while negative outcomes or punishments only slightly weakened the association.
The Law of Effect is important as it was a precursor to B.F. Skinner's operant conditioning, influencing the development of behaviorism in the first half of the 20th century. Skinner built upon Thorndike's contributions to the psychology of learning, formalizing the process of operant conditioning as the explanatory basis of human behavior. Thorndike's Law of Effect is a well-known and influential theory that continues to shape our understanding of learning and behavior.

Frequently asked questions
The law of effect, also known as Thorndike's law, was developed by American psychologist Edward Thorndike.
The law of effect was published by Edward Thorndike in 1905 and later modified in 1932.
The law of effect states that responses that produce a satisfying effect in a particular situation are likely to occur again in a similar situation. Conversely, responses that produce a discomforting effect are less likely to occur again in that situation.
Thorndike's experiments with cats in puzzle boxes are a well-known example of the law of effect. In these experiments, a cat was placed in a box with a lever that, when pressed, would open a door and allow the cat to escape and obtain food. Over time, the cat learned to associate pressing the lever with its escape and access to food, and became faster at pressing the lever on subsequent trials.
