To explore the complex workings of the human mind, psychologists have developed many theories over the years. Some theories focus on individual behavior, while others focus on group behavior. Five main ideas have emerged among these theories as the most influential and widely accepted.

 

What are the Five Main Theories in Psychology?

Here are five main theories in psychology that have helped shape our understanding of human behavior.

 

Psychodynamic Theory

Psychodynamic Theory, also known as Freudian Theory, is one of the oldest theories in psychology. It was developed by Austrian psychiatrist Sigmund Freud and focuses on the role of the unconscious mind in shaping behavior.

Freud believed that our early childhood experiences significantly impact our adult lives and that much of our behavior is determined by our unconscious mind.

By understanding the role of the unconscious mind, Freud believed that we could better understand and treat psychological disorders.

 

Behaviorism or Behavioral Theory

Behavioral Theory, developed by B. F. Skinner, focuses on the role of reinforcement in shaping behavior.

Behaviorism is the theory that all behavior is learned through conditioning—either through reinforcement (rewarding the desired behavior) or punishment (discouraging an undesired behavior).

Behaviorism began as a reaction to the traditional theories in psychology, which focused on mental states and internal thoughts and emotions. Behaviorists believe that all behavior results from conditioning and can be studied scientifically without reference to internal mental states.

The two main types of conditioning are classical conditioning and operant conditioning.

Classical Conditioning

Classical conditioning is learning that occurs when two stimuli are paired together. The first stimulus is known as the conditioned stimulus, and the second stimulus is known as the unconditioned stimulus.

The unconditioned stimulus is a stimulus that naturally leads to a particular response. The conditioned stimulus is a stimulus that does not naturally lead to the particular response but does so after being paired with the unconditioned stimulus.

For example, let’s think about a rat in a lab. Every time a lever is pressed, the rat gets a piece of food. The lever is the conditioned stimulus, and the food is the unconditioned stimulus. After a while, the rat learns to associate the lever with the food and presses it to make food appear. This is an example of classical conditioning.

Operant Conditioning

Operant conditioning is a type of learning that occurs as a result of a behavior. If a behavior is followed by a positive consequence (reinforcement), it is more likely to be repeated. If a behavior is followed by a negative consequence (punishment), it is less likely to be repeated.

The four basic principles of operant conditioning are:

  • Positive reinforcement
  • Negative reinforcement
  • Positive punishment
  • Negative punishment

Each of these principles is based on the consequence of a behavior.

Positive Reinforcement

Positive reinforcement is the addition of a desirable consequence after a behavior is displayed to increase the likelihood of that behavior being repeated. Like classical conditioning, operant conditioning occurs as a result of an association being made between two stimuli.

In the case of positive reinforcement, the association is between the behavior and the reinforcement. The most common type of positive reinforcement is a reward.

For example, if you finish your homework and get a piece of candy, the candy is a reward that positively reinforces the behavior (finishing homework).

Negative Reinforcement

Negative reinforcement removes an undesirable consequence after a behavior is displayed to increase the likelihood of that behavior being repeated.

For example, you’re studying for a test and take a break after every hour of studying. In that case, removing the undesirable consequence (studying) increases the likelihood of the behavior (taking a break) being repeated.

Positive Punishment

Positive punishment is the addition of an undesirable consequence after a behavior is displayed to decrease the likelihood of that behavior being repeated.

For example, if you hit your brother and your brother hits you, the hitting is a positive punishment that decreases the likelihood of you hitting your brother again.

Negative Punishment

Negative punishment is the removal of a desirable consequence after a behavior is displayed to decrease the likelihood of that behavior being repeated. 

For example, if a child puts their hand in a fire and gets burned, they will take their hand away, so in the future, they will avoid being burned again. This is an example of negative punishment.

 

Social Learning Theory

The social learning theory is a theory that suggests people learn by observing the behaviors of others. Albert Bandura, a well-known psychologist, first proposed this theory.

Bandura’s theory has three main components:

  • Observational learning
  • Modeling
  • Reinforcement

Social learning theory, which is one of the main theories in psychology, with the 3 main components, observational learning, reinforcement and modeling.

Observational Learning

Observational learning occurs when people observe the behaviors of others and then imitate those behaviors. Bandura believes that people learn by observing the behaviors of others and then imitating those behaviors.

Modeling

Modeling is the process of observing and then imitating the behavior of others.

Reinforcement

Reinforcement is when someone is rewarded for exhibiting the desired behavior. This reinforces the desired behavior and makes it more likely that the person will continue to exhibit that behavior.

 

The Cognitive Theory

Cognitive theory is one of the main theories in psychology, focusing on how people process information. Jean Piaget proposed this theory, and many other psychologists have since developed it.

This theory suggests that people learn by constructing their own knowledge. This means that people learn by actively trying to make sense of the world around them. This theory has been used to explain how people learn new skills and gain knowledge.

Cognitive theory has also been used to explain how people retain information. This theory suggests that people store information in their memories by creating mental representations. These mental representations can be based on previous experiences or information that has been heard or read.

The theory has been used to explain a range of human behaviors. For example, this theory explains how people make decisions, how they solve problems, and how they remember information.

Four Stages of Piaget’s Cognitive Development

According to the cognitive theory, people go through four main stages of development: the sensorimotor stage, preoperational stage, concrete operational stage, and formal operational stage.

1.Sensorimotor Stage:

This is the first stage of development, lasting from birth until around two years of age. During this stage, babies learn about the world through their senses and by exploring their environment.

2.Preoperational Stage:

This second development stage lasts from around two to seven years of age. During this stage, children learn to use symbols and language. This is when children first start to think about the world in terms of symbols.

Some of the main characteristics of this stage are egocentrism and animism.

Egocentrism

Egocentrism is when children believe that everyone sees the world from their own perspective. Children at this stage of development often have difficulty understanding that other people have different points of view.

Animism

Animism is when children believe that inanimate objects are alive. For example, a child might believe that a doll is a real person.

3.Concrete Operational Stage:

This is the third development stage, lasting from around seven until eleven years of age. During this stage, children learn to think logically about concrete events. This is the period when children first start to think scientifically.

The main characteristics of this stage are conservation and decantation.

Conservation

Conservation is when children understand that certain properties of an object remain the same despite changes in its appearance. For example, a child might understand that a glass of water is still the same even if it is poured into a different container.

Decantation

Decantation is when children learn to separate a mixture into its component parts. For example, a child might learn to separate salt and water by evaporating it.

4.Formal Operational Stage:

This is the fourth stage of development, starting around eleven years of age. During this stage, people learn to think abstractly and use logic to solve problems. This is the period when people first start to think about hypothetical situations.

The main characteristics of this stage are hypothetical thinking and deductive reasoning.

Hypothetical Thinking

Hypothetical thinking is when people can think about possible events. For example, a person might think about what would happen if they won the lottery.

Deductive Reasoning

Deductive reasoning is when people can use logical reasoning to solve problems. For example, a person might use deductive reasoning to learn how to get from one place to another by remembering landmarks they have previously seen.

The theories in psychology are constantly evolving and expanding. The cognitive theory is just one of the many theories developed to explain human behavior.

 

The Humanistic Theory

The humanistic theory is a psychological theory that emphasizes the unique qualities of humans and the personal quest for fulfillment. This theory was developed in response to theories emphasizing human nature’s dark side.

The main theorists associated with humanistic theory are Carl Rogers and Abraham Maslow. Humanistic theory is based on the belief that people are innately good and that they have the potential to grow and develop into their best selves. 

This theory emphasizes the need for humans to be self-actualized, which means they must reach their full potential. Maslow’s hierarchy of needs is a key component of the humanistic theory. This hierarchy includes the needs for safety, love and belonging, esteem, and self-actualization.

The humanistic theory has had a significant impact on education and therapy. This theory emphasizes the importance of meeting the whole person’s needs, which is why it is often used in humanistic therapies such as person-centered therapy. 

This theory also emphasizes the importance of creating a learning environment that is supportive and nurturing.

Strengths of Humanistic Theory

The humanistic theory has both strengths and weaknesses. One strength of this theory is that it provides a more optimistic view of human nature than some of the other theories. Another strength is that it recognizes the importance of meeting the whole person’s needs.

Weakness of humanistic Theory

A weakness of this theory is that it does not always provide clear guidelines for achieving self-actualization. Another weakness is that it does not always consider the role of biology in human behavior. Overall, the humanistic theory is a valuable perspective that provides insights into the nature of humans and the personal quest for fulfillment.

 

Final Thoughts

These five theories are just a few of the many theories developed to explain human behavior. Each theory has its own strengths and weaknesses, but they all provide valuable insights into the nature of humans. The theories in psychology constantly evolve and expand, so there is always more to learn about the complexities of the human mind.
