The Law of Effect, also known as Thorndike's Law of Effect, was developed by psychologist Edward Thorndike in the early 20th century. It is a principle of behavioral conditioning that states that responses resulting in positive outcomes in a given situation will be repeated, while those leading to negative outcomes will not. Thorndike's work, particularly his experiments with animals, laid the foundation for B.F. Skinner's operant conditioning and significantly influenced the field of behaviorism. While the Law of Effect is commonly attributed to Thorndike, it is essential to recognize that other theorists, such as Silvan Tomkins and Baruch Spinoza, have contributed to the broader understanding of affect and its role in various disciplines, including philosophy, psychology, and literary criticism.

What You'll Learn
Edward L. Thorndike's experiments with cats
The American psychologist Edward L. Thorndike is commonly attributed for discovering the law of effect, a foundational principle in psychology. Thorndike's research on learning and behavior, particularly his work with animals in the late 19th and early 20th centuries, led to the formulation of this principle.
Thorndike's experiments with cats in puzzle boxes demonstrated how animals learn from consequences. In these experiments, hungry cats were placed in a box that could be opened if the cat pressed a lever or pulled a loop. Food was placed outside the box, acting as a reward for escaping. Initially, the cats tried various random behaviors to escape, such as scratching at the door or jumping. Over time, they learned to repeat the behaviors that successfully led to their escape, demonstrating the law of effect.
During the first few trials, Thorndike observed that the cats responded in many ineffective ways before finally freeing themselves through trial and error. With each successive trial, the cats took less time to escape as they learned from their previous experiences. This highlighted the importance of reinforcement in learning and behavior modification, which became a key concept in operant conditioning.
Thorndike's work laid the foundation for future research in psychology, particularly in understanding operant conditioning and behaviorism. His findings influenced the understanding of how behavior is shaped and learned, impacting both psychology and education. The law of effect states that responses that lead to satisfying consequences are more likely to be repeated, while those resulting in unsatisfying outcomes are less likely to recur.
In addition to his work with cats, Thorndike also introduced the law of exercise in his doctoral dissertation, published in 1911 as "Animal Intelligence." The law of exercise states that behavior is more strongly established through frequent connections between stimulus and response. Thorndike's contributions to the field of psychology have had a lasting impact, influencing later psychologists such as B.F. Skinner.

The law's influence on psychology
The law of affect, also known as the law of effect, is commonly attributed to the American psychologist Edward L. Thorndike. The law of affect is a foundational principle in psychology that states that responses that lead to satisfying consequences are likely to be repeated, while those resulting in unsatisfying outcomes are less likely to recur. This concept has played a pivotal role in the development of behaviorism and operant conditioning, influencing our understanding of how behavior is shaped and learned.
Thorndike's research on animal behavior and the learning process laid the foundation for future research in psychology. His work, particularly his experiments with cats in puzzle boxes, demonstrated how animals learn from the consequences of their actions. This led to the theory of connectionism, which states that behavioral responses to specific stimuli are established through a process of trial and error that affects neural connections between the stimuli and the most satisfying responses.
The law of affect has had a significant influence on the field of psychology. It has provided valuable insights into the learning process and has been applied in various areas of psychology, including education and behavior modification. For example, in training pets, the principle of reinforcement is utilized to encourage desired behaviors. Similarly, students may be motivated to repeat certain behaviors, such as studying hard for an exam, if they receive a high grade as a consequence.
Additionally, the law of affect has contributed to our understanding of the role of emotions in social interactions. Evolutionary psychologists have hypothesized that hominids have evolved with a sophisticated capability of reading and displaying emotions, which mediate their relationship with their continually changing social environment. This suggests that emotions are dynamic processes that play a crucial role in establishing, maintaining, or disrupting relationships between individuals and their environment.
The law of affect has also been incorporated into couples therapy, with the Emotional Safety model seeking to identify the affective messages within a couple's emotional relationship. According to Tomkins, a central characteristic of affects is affective resonance, which refers to the tendency of individuals to experience the same affect when viewing a display of that affect by another person.
Furthermore, the law of affect has implications for understanding the interplay between affect, cognition, and emotional development. While initial theories suggested that affect was post-cognitive, requiring prior cognitive processing, subsequent scholars have argued that affect can be both pre- and post-cognitive, with initial emotional responses producing thoughts that then produce affect. This indicates that affect may enable more rational modes of cognition.

Classical conditioning
The law of effect, which states that responses with satisfying or positive consequences are repeated, is commonly attributed to the American psychologist Edward L. Thorndike. Thorndike's work on animal behaviour and the learning process in the late 19th and early 20th centuries led to the theory of connectionism, which states that behavioural responses to specific stimuli are established through a process of trial and error that affects neural connections.
Thorndike's most famous experiments involved placing cats in a puzzle box, where they had to learn to escape to receive a reward (usually food). Initially, the cats would try various random behaviours to escape, but over time, they learned to repeat the behaviours that successfully led to their escape. With each successive trial, it took the cats, on average, less time to escape. Thus, the correct response was reinforced by its consequence, release from the box.
Thorndike's findings were based on systematic observations and experiments, providing empirical evidence for his theories. His work laid the foundation for future research in psychology, particularly in understanding operant conditioning and the development of behaviourism. The law of effect played a pivotal role in influencing the understanding of how behaviour is shaped and learned.
B.F. Skinner is commonly attributed with expanding on Thorndike's law of effect. Skinner conducted experiments using operant conditioning, where animals learned behaviours through consequences in a Skinner box. Skinner's work demonstrated how organisms learn and modify their behaviour based on the outcomes they experience, supporting Thorndike's law of effect. Through experiments with rats and pigeons, Skinner showed that behaviours leading to rewards were reinforced, illustrating the principle of operant conditioning.

Operant conditioning
Thorndike's work laid the foundation for future research in psychology, particularly in understanding operant conditioning, and his findings continue to influence the fields of psychology, education, and behaviour studies. The law of effect is a foundational principle in psychology, and it highlights the importance of reinforcement in learning and behaviour modification.
B.F. Skinner is commonly attributed with expanding on Thorndike's law of effect through his research in operant conditioning. Skinner conducted experiments using a 'Skinner box', where animals learned behaviours through consequences. Skinner's work demonstrated how organisms learn and modify their behaviour based on the outcomes they experience, supporting Thorndike's law of effect. Through experiments with rats and pigeons, Skinner showed that behaviours leading to rewards were reinforced, further illustrating the principle of operant conditioning.
In summary, Edward L. Thorndike is credited with discovering the law of effect through his experiments with animals, and his work laid the groundwork for future behavioural theories. B.F. Skinner later expanded upon Thorndike's concepts through his research in operant conditioning, demonstrating how consequences influence behaviour.

The law's influence on education
The Law of Affect, also known as the Law of Effect, was formulated by the American psychologist Edward L. Thorndike. Thorndike's research on learning and behaviour, particularly his work with animals in the late 19th and early 20th centuries, led to the formulation of this principle. The law of affect states that responses that lead to satisfying consequences are likely to be repeated, while those resulting in unsatisfying outcomes are less likely to recur.
The Law of Affect has had a significant influence on the field of education, with its principles being applied in various ways to enhance teaching and learning. Firstly, the law highlights the importance of reinforcement in learning and behaviour modification. For example, when a student studies hard for an exam and receives a high grade, they are likely to repeat this behaviour in the future to achieve similar results. This understanding of reinforcement has led to the development of strategies such as positive reinforcement in the classroom, where teachers reward desired behaviours to increase the likelihood of them reoccurring.
Additionally, the Law of Affect has contributed to our understanding of operant conditioning, which is the process by which behaviour is shaped and learned. This has had a significant impact on educational psychology and the development of behaviourist theories of learning. By understanding how behaviours can be modified by their consequences, educators can create learning environments that encourage positive behaviours and discourage negative ones.
The law has also influenced the way educators design instruction and curriculum. For instance, educators may structure lessons to provide students with opportunities to experience success and receive positive feedback, reinforcing desired behaviours and promoting a growth mindset. Furthermore, the Law of Affect has played a role in shaping educational policies and practices related to student motivation and engagement. Schools may implement strategies to increase student motivation by creating opportunities for students to experience success and receive rewards for their efforts.
In addition to its impact on general education, the Law of Affect has had a particular influence on special education. The understanding that behaviours are shaped by their consequences has contributed to the development of interventions and strategies to support students with special needs. For example, applied behaviour analysis (ABA) therapy, commonly used with children with autism, is based on the principles of operant conditioning, utilising positive reinforcement to increase desirable behaviours and decrease undesirable ones.
Overall, the Law of Affect has had a profound and lasting impact on education, influencing teaching practices, curriculum design, student motivation, and the support provided to students with special needs. By understanding the relationship between behaviour and its consequences, educators can create effective learning environments that promote positive behaviours and enhance student learning.

Frequently asked questions
The law of affect, or Thorndike's law, is commonly attributed to and was discovered by psychologist Edward Thorndike.
The law of effect was published by Edward Thorndike in 1905, although some sources state he advanced the theory in 1898. Thorndike modified the law in 1932.
The law of effect is a psychology principle concerning behavioral conditioning. It states that responses that produce a satisfying effect in a particular situation are likely to recur in that situation, while responses that produce a discomforting effect are less likely to occur again in that situation.
Thorndike's law of effect was developed through experiments with animals, typically cats. In one experiment, Thorndike placed a cat in a puzzle box with a small lever on one side. The cat could only escape by pressing the lever. By timing how long it took the cat to escape the box, Thorndike found that the cat learned to press the lever more quickly when rewarded with food and freedom.
The law of effect was a precursor to B.F. Skinner's operant conditioning. Thorndike's work had a major influence on behaviorism and the understanding of how people learn.
