In the realm of psychology, the term ‘instrumental’ often relates to a method or means of achieving a desired outcome. This introduction will explore the instrumental concept within psychological frameworks, trace its historical development, and provide concrete examples.
Instrumental methods are foundational in various psychological applications, from therapeutic techniques to educational strategies. The historical context dates back to the early studies of behaviorism, where the focus was on observable behaviors and the environmental factors influencing them. Examples of instrumental approaches in psychology include operant conditioning and instrumental learning, where behaviors are shaped by rewards or punishments.
Furthermore, the introduction will delineate related terms that enrich the understanding of instrumental methods in psychological practice. References to seminal works and contemporary studies will be provided to substantiate the discourse.
Definition
Instrumental in psychology refers to a learning process where behavior is shaped through consequences. It involves using rewards or punishments to increase or decrease the likelihood of a behavior happening again.
This approach focuses on observable data to understand how actions and outcomes are related, and it is an important aspect of behavioral psychology.
History
Operant conditioning, also known as instrumental learning, originated in the early 20th century and was pioneered by psychologist B.F. Skinner. However, the foundations of this concept can be traced back to the work of Edward Thorndike, another influential behaviorist. Thorndike proposed the law of effect, which stated that behaviors followed by positive consequences are more likely to be repeated, while behaviors followed by negative consequences are less likely to be repeated.
Skinner built upon Thorndike’s ideas and conducted extensive research to further develop the concept of operant conditioning. His methodical experimentation and analytical approach allowed for the formulation of fundamental principles in this field. One of the key contributions of Skinner was the identification of reinforcement schedules, which refer to the timing and pattern of rewards or punishments following a behavior.
Skinner also introduced the concept of shaping, which involves selectively reinforcing behaviors that gradually approximate the desired behavior. Skinner’s work in operant conditioning revolutionized the understanding of learning processes in both humans and animals. His contributions provided a systematic framework for observing and studying behavioral changes over time.
Skinner’s research laid the foundation for empirical studies on learning, and his ideas continue to be influential in the field of behavioral psychology. Overall, the historical background of operant conditioning involves the pioneering work of B.F. Skinner, building upon the principles established by Edward Thorndike. Skinner’s systematic experimentation and formulation of fundamental principles greatly contributed to the evolution of this psychology term. His work continues to shape our understanding of how behaviors are shaped and maintained by consequences, making operant conditioning a crucial concept in psychology.
Examples
Operant conditioning is a psychological concept that can be seen in everyday situations. For example, consider a child who receives a small toy every time they finish their homework (positive reinforcement). This positive reward encourages the child to continue completing their homework in the future.
In a work setting, an employee may receive a bonus or a promotion for meeting their sales targets (positive reinforcement). This motivates them to continue performing well and achieving their goals.
On the other hand, negative reinforcement can also be observed in real-life scenarios. For instance, imagine a person who hates doing household chores. One day, they realize that if they clean the house thoroughly, their partner will stop nagging them about it (negative reinforcement). This relief from the nagging serves as an incentive for the person to continue cleaning the house regularly.
In a sports context, think about a basketball player who consistently misses free throws during practice. As a consequence, the coach makes them run extra laps (negative reinforcement). The player quickly realizes that by improving their free-throw skills, they can avoid the unpleasant punishment of running laps.
These examples demonstrate how operant conditioning is present in various aspects of our lives. Whether it’s in education, work, household responsibilities, or sports, the principles of operant conditioning can shape our behaviors and motivate us to continue engaging in certain actions.
Related Terms
Several related concepts in psychology intersect with operant conditioning, including classical conditioning, reinforcement schedules, and behavior modification.
Classical conditioning, originally described by Ivan Pavlov, involves learning through association and differs from operant conditioning, which is learning based on consequences. While operant conditioning focuses on the relationship between behavior and its consequences, classical conditioning focuses on the association between stimuli and responses. In classical conditioning, a neutral stimulus is paired with an unconditioned stimulus to elicit a conditioned response. In contrast, operant conditioning involves the use of reinforcements or punishments to strengthen or weaken a behavior.
Reinforcement schedules, a key component of operant conditioning formulated by B.F. Skinner, determine the timing and frequency of reinforcements, shaping the acquisition and maintenance of behaviors. These schedules can be classified as fixed or variable, and as interval or ratio schedules. Fixed interval schedules provide reinforcement after a fixed amount of time has elapsed, while variable interval schedules provide reinforcement after varying amounts of time. Similarly, fixed ratio schedules provide reinforcement after a fixed number of responses, while variable ratio schedules provide reinforcement after varying numbers of responses. Reinforcement schedules play a crucial role in shaping behavior by influencing the predictability and consistency of reinforcement.
Behavior modification encompasses strategies to alter behavior patterns, utilizing principles from both operant and classical conditioning. It aims to replace undesirable behaviors with more adaptive responses using a variety of reinforcement and punishment techniques. While operant conditioning primarily focuses on modifying voluntary behaviors through reinforcement, behavior modification can also incorporate classical conditioning techniques to address involuntary behaviors or emotional responses. By utilizing the principles of operant and classical conditioning, behavior modification provides a comprehensive approach to behavior change.
These foundational elements – operant conditioning, classical conditioning, reinforcement schedules, and behavior modification – exhibit a complex interplay in the orchestration of learning and behavior. Together, they provide a framework for understanding how behaviors are learned, maintained, and modified in response to environmental stimuli and consequences.

Numerous studies and seminal works have contributed to the understanding and development of instrumental conditioning in psychology. These foundational texts have systematically delineated the parameters of the conditioning process, exploring the nuances of stimulus-response relationships, and the role of reinforcement and punishment in behavior modification.
In particular, the empirical research and theoretical formulations of pioneers such as Edward L. Thorndike and B.F. Skinner have established a framework within which subsequent investigations and applications have been grounded (Thorndike, 1898; Skinner, 1938).
Scholarly articles, controlled experiments, and longitudinal studies have further refined the concept of instrumental conditioning, offering a robust body of evidence that supports its efficacy and applicability. For example, a study by Galla and Duckworth (2015) demonstrated the effectiveness of instrumental conditioning in promoting academic achievement among high school students. Similarly, a comprehensive review by Lattal and Chase (2003) examined the various factors that influence instrumental conditioning, including the timing and magnitude of reinforcement.
