What perspective is Psychological Science is the study of behavior that is observable and measurable?

Psychology is the scientific study of human and animal behavior, which includes both observable actions (such as eating and speaking) and mental activities (such as remembering and imagining). Psychology tries to understand why a person or animal behaves a certain way and then seeks to predict how that person or animal will behave in the future. For many years, psychology was a branch of philosophy (the study and exploration of basic truths governing the universe, nature, life, and morals [a sense of right and wrong]). In the nineteenth century, scientific findings established it as a separate field of scientific study.

A brief history

In 1879, German physiologist Wilhelm Wundt (1832–1920) established the first formal laboratory of psychology at the University of Leipzig in Germany. Wundt's work separated thought into simpler processes such as perception, sensation, emotion, and association. His approach looked at the structure of thought and came to be known as structuralism.

In 1890, American philosopher William James (1842–1910) published his Principles of Psychology. In contrast to structuralists, James thought consciousness (awareness) flowed continuously and could not be separated into simpler elements. James argued that studying the structure of the mind was not as important as understanding how it functions in helping us adapt to our surroundings. This approach became known as functionalism.

In the early 1900s, Austrian neurologist Sigmund Freud (1856–1939) began formulating psychoanalysis, which is both a theory of personality and a method of treating people with psychological difficulties. Freud's most influential contribution to psychology was his concept of the unconscious. He believed a person's behavior is largely determined by thoughts, wishes, and memories of which they are unaware. Painful childhood memories are pushed out of consciousness and become part of the un conscious. From here they can greatly influence behavior. As a method of treatment, psychoanalysis strives to bring these memories to awareness, freeing an individual from their often-negative influence.

In 1913, American psychologist John B. Watson (1878–1958) argued that mental processes could not be reliably located or measured. He believed that only observable, measurable behavior should be the focus of psychology. His approach, known as behaviorism, held that all behavior could be explained as a response to stimuli in the environment. Behaviorists tend to focus on the environment and how it shapes behavior.

Behaviorism: School of psychology focusing on the environment and how it shapes behavior.

Cognitive psychology: School of psychology that focuses on how people perceive, store, and interpret information through such thought processes as memory, language, and problem solving.

Functionalism: School of psychology that focuses on the functions or adaptive purposes of behavior.

Gestalt psychology: School of psychology that focuses on perception and how the mind actively organizes sensations.

Humanistic psychology: School of psychology emphasizing individuals' uniqueness and their capacity for growth.

Neuropsychology: Study of the brain and nervous system and their role in behavior and mental processes.

Psychoanalysis: Theory of personality and method of psychotherapy founded by Sigmund Freud.

At about the same time behaviorism arose, German psychologists Max Wertheimer (1880–1943), Kurt Koffka (1886–1941), and Wolfgang Köhler (1887–1967) founded Gestalt psychology (German for "form" or "configuration"). Gestalt psychologists argued that perception and thought cannot be broken into smaller pieces without losing their wholeness or essence. They argued that people actively organize information and that the wholeness and pattern of things dominates the way people perceive the world.

In the 1960s, American psychologists Abraham Maslow (1908–1970) and Carl Rogers (1902–1987) helped develop humanistic psychology. They felt that past psychological approaches had focused more on human weakness and mental illness. These previous approaches neglected mental strength and the potential for self-fulfillment. Maslow and Rogers believed that everyone has a basic need to achieve one's unique human potential.

Contemporary psychology

Much contemporary research has taken place in cognitive psychology. This school of psychology focuses on how people perceive, store, and interpret information, studying processes like memory, language, and problem solving. Unlike behaviorists, cognitive psychologists believe it is necessary to look at internal mental processes in order to understand behavior.

Advances in the knowledge of brain and nerve cell chemistry in the late twentieth century have influenced psychology tremendously. New technologies, which have produced visual images of the human brain at work, have allowed psychologists to study exactly where specific types of mental processes occur. This emerging field has been labeled neuropsychology or neuroscience.

Behaviorism is a theory of learning based on the idea that all behaviors are acquired through conditioning, and conditioning occurs through interaction with the environment. Behaviorists believe that our actions are shaped by environmental stimuli.

In simple terms, according to this school of thought, also known as behavioral psychology, behavior can be studied in a systematic and observable manner regardless of internal mental states. Behavioral theory also says that only observable behavior should be studied, as cognition, emotions, and mood are far too subjective.

Strict behaviorists believe that any person—regardless of genetic background, personality traits, and internal thoughts— can be trained to perform any task, within the limits of their physical capabilities. It only requires the right conditioning.

Behaviorism was formally established with the 1913 publication of John B. Watson's classic paper, "Psychology as the Behaviorist Views It." It is best summed up by the following quote from Watson, who is often considered the father of behaviorism:

"Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select—doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors."

Simply put, strict behaviorists believe that all behaviors are the result of experience. Any person, regardless of their background, can be trained to act in a particular manner given the right conditioning.

From about 1920 through the mid-1950s, behaviorism became the dominant school of thought in psychology. Some suggest that the popularity of behavioral psychology grew out of the desire to establish psychology as an objective and measurable science.

During that time, researchers were interested in creating theories that could be clearly described and empirically measured, but also used to make contributions that might have an influence on the fabric of everyday human lives.

There are two main types of behaviorism used to describe how behavior is formed.

Methodological behaviorism states that observable behavior should be studied scientifically and that mental states and cognitive processes don't add to the understanding of behavior. Methodological behaviorism aligns with Watson's ideologies and approach.

Radical behaviorism is rooted in the theory that behavior can be understood by looking at one's past and present environment and the reinforcements within it, thereby influencing behavior either positively or negatively. This behavioral approach was created by the psychologist B.F. Skinner.

Classical conditioning is a technique frequently used in behavioral training in which a neutral stimulus is paired with a naturally occurring stimulus. Eventually, the neutral stimulus comes to evoke the same response as the naturally occurring stimulus, even without the naturally occurring stimulus presenting itself.

Throughout the course of three distinct phases of classical conditioning, the associated stimulus becomes known as the conditioned stimulus and the learned behavior is known as the conditioned response.

The classical conditioning process works by developing an association between an environmental stimulus and a naturally occurring stimulus.

In physiologist Ivan Pavlov's classic experiments, dogs associated the presentation of food (something that naturally and automatically triggers a salivation response) at first with the sound of a bell, then with the sight of a lab assistant's white coat. Eventually, the lab coat alone elicited a salivation response from the dogs.

During the first part of the classical conditioning process, known as acquisition, a response is established and strengthened. Factors such as the prominence of the stimuli and the timing of the presentation can play an important role in how quickly an association is formed.

When an association disappears, this is known as extinction. It causes the behavior to weaken gradually or vanish. Factors such as the strength of the original response can play a role in how quickly extinction occurs. The longer a response has been conditioned, for example, the longer it may take for it to become extinct.

Operant conditioning, sometimes referred to as instrumental conditioning, is a method of learning that occurs through reinforcement and punishment. Through operant conditioning, an association is made between a behavior and a consequence for that behavior.

This behavioral approach says that when a desirable result follows an action, the behavior becomes more likely to happen again in the future. Conversely, responses followed by adverse outcomes become less likely to reoccur.

Behaviorist B.F. Skinner described operant conditioning as the process in which learning can occur through reinforcement and punishment. More specifically: By forming an association between a certain behavior and the consequences of that behavior, you learn.

For example, if a parent rewards their child with praise every time they pick up their toys, the desired behavior is consistently reinforced and the child will become more likely to clean up messes.

The process of operant conditioning seems fairly straightforward—simply observe a behavior, then offer a reward or punishment. However, Skinner discovered that the timing of these rewards and punishments has an important influence on how quickly a new behavior is acquired and the strength of the corresponding response.

This makes reinforcement schedules important in operant conditioning. These can involve either continuous or partial reinforcement.

  • Continuous reinforcement involves rewarding every single instance of a behavior. It is often used at the beginning of the operant conditioning process. Then, as the behavior is learned, the schedule might switch to one of partial reinforcement.
  • Partial reinforcement involves offering a reward after a number of responses or after a period of time has elapsed. Sometimes, partial reinforcement occurs on a consistent or fixed schedule. In other instances, a variable and unpredictable number of responses or amount of time must occur before the reinforcement is delivered.

The behaviorist perspective has a few different uses, including some related to education and mental health.

Behaviorism can be used to help students learn, such as by influencing lesson design. For instance, some teachers use consistent encouragement to help students learn (operant conditioning) while others focus more on creating a stimulating environment to increase engagement (classical conditioning).

One of the greatest strengths of behavioral psychology is the ability to clearly observe and measure behaviors. Because behaviorism is based on observable behaviors, it is often easier to quantify and collect data when conducting research.

Behavioral therapy was born from behaviorism and originally used in the treatment of autism and schizophrenia. This type of therapy involves helping people change problematic thoughts and behaviors, thereby improving mental health.

Effective therapeutic techniques such as intensive behavioral intervention, behavior analysis, token economies, and discrete trial training are all rooted in behaviorism. These approaches are often very useful in changing maladaptive or harmful behaviors in both children and adults.

Several thinkers influenced behavioral psychology. Among these are Edward Thorndike, a pioneering psychologist who described the law of effect, and Clark Hull, who proposed the drive theory of learning.

There are a number of therapeutic techniques rooted in behavioral psychology. Though behavioral psychology assumed more of a background position after 1950, its principles still remain important.

Even today, behavior analysis is often used as a therapeutic technique to help children with autism and developmental delays acquire new skills. It frequently involves processes such as shaping (rewarding closer approximations to the desired behavior) and chaining (breaking a task down into smaller parts, then teaching and chaining the subsequent steps together).

Many critics argue that behaviorism is a one-dimensional approach to understanding human behavior. They suggest that behavioral theories do not account for free will or internal influences such as moods, thoughts, and feelings.

Freud, for example, felt that behaviorism failed by not accounting for the unconscious mind's thoughts, feelings, and desires, which influence people's actions. Other thinkers, such as Carl Rogers and other humanistic psychologists, believed that behaviorism was too rigid and limited, failing to take into consideration personal agency.

More recently, biological psychology has emphasized the role the brain and genetics play in determining and influencing human actions. The cognitive approach to psychology focuses on mental processes such as thinking, decision-making, language, and problem-solving. In both cases, behaviorism neglects these processes and influences in favor of studying only observable behaviors.

Behavioral psychology also does not account for other types of learning that occur without the use of reinforcement and punishment. Moreover, people and animals can adapt their behavior when new information is introduced, even if that behavior was established through reinforcement.

While the behavioral approach might not be the dominant force that it once was, it has still had a major impact on our understanding of human psychology. The conditioning process alone has been used to understand many different types of behaviors, ranging from how people learn to how language develops.

But perhaps the greatest contributions of behavioral psychology lie in its practical applications. Its techniques can play a powerful role in modifying problematic behavior and encouraging more positive, helpful responses. Outside of psychology, parents, teachers, animal trainers, and many others make use of basic behavioral principles to help teach new behaviors and discourage unwanted ones.

Frequently Asked Questions

  • John B. Watson is known as the founder of behaviorism. Though others had similar ideas in the early 1900s, when behavioral theory began, some suggest that Watson is credited as behavioral psychology's founder due to being "an attractive, strong, scientifically accomplished, and forceful speaker and an engaging writer" who was willing to share this behavioral approach when other psychologists were less likely to speak up.

  • How is behaviorism used in education?

    Behaviorism can be used to help elicit positive behaviors or responses in students, such as by using reinforcement. Teachers with a behavioral approach often use "skill and drill" exercises to reinforce correct responses through consistent repetition, for instance.

    Other ways reinforcement-based behaviorism can be used in education include praising students for getting the right answer and providing prizes for those who do well. Using tests to measure performance enables teachers to measure observable behaviors and is, therefore, another behavioral approach.

  • What makes behaviorism different from psychoanalysis?

    Behaviorism says that behavior is a result of environment, the environment being an external stimulus. Psychoanalysis is the opposite of this, in that it is rooted in the belief that behavior is a result of an internal stimulus. Psychoanalytic theory is based on behaviors being motivated by one's unconscious mind, thus resulting in actions that are consistent with their unknown wishes and desires.

  • What is cognitive behaviorism?

    Whereas strict behaviorism has no room for cognitive influences, cognitive behaviorism operates on the assumption that behavior is impacted by thoughts and emotions. Cognitive behavioral therapy (CBT), for instance, attempts to change negative behaviors by changing the destructive thought patterns behind them.
