Perhaps the most famous of them all, Sigmund Freud is known as the father of psychoanalysis. The latter seeks to deconstruct the workings of the unconscious mind while employing a therapeutic approach to mental and emotional distress. According to Freud, the unconscious mind harbors repressed memories and desires or fears, which ultimately influence how human beings behave or think. Freud is also credited for his work in the interpretation of dreams, and psychosexual development.

Carl Rogers was an American psychologist, born in Illinois on January 8, 1902. He is known as one of the main founders of the humanistic and client-centered approach to psychology.  Among his propositions is the theory that individuals are in a continually changing environment, of which they are the center. This is their phenomenal field. His emphasis on self-actualization, and a therapeutic and empathetic approach that focuses on the client have been employed in psychological counseling.

4. John B. Watson

Watson was an American psychologist known for his significant contribution to classical behaviorism in psychology. He was born on January 9, 1878, in South Carolina. His approach was that behavior was the manifestation of conditioned response to external stimuli as well as inner processes. He employed his theories in child psychology, demonstrating that a child’s behavior was influenced by their environment and surrounding stimuli.

Watson is also associated with the controversial Little Albert experiment which demonstrated conditioning in children. In short, the experiment showed that when a particular stimulus was associated with an unrelated one, it affected the child’s response. In this case, a child that was previously unafraid of a rat became afraid of it after a series of loud noises was associated with it. Watson is considered one of the most cited psychologists of the 20^th century.

5. Alfred Binet

Intelligence testing has undergone tremendous technological advancement, and Alfred Binet laid its foundations. The French psychologist was born in Nice, on 8 July 1857. He is best known for having invented the first practical IQ test. It was called the Binet-Simon test, and it aimed to identify the intellectual capabilities of children to identify the ones that needed help outside the regular learning process.

Alfred held that by comparing same-age children’s performance on a similar idea, he could identify those whose intelligence was below average. His work was instrumental in developing the concept of the intelligence quotient and mental age. He also highlighted the need to appreciate individual differences since intelligence was a complex construct. Chronological age was insufficient in understanding or gauging one’s intelligence. His work offered a standardized approach to the measurement of intellectual capabilities.

6. Alfred Adler

Adler was an Austrian psychiatrist known for his founding work on individual psychology. He focused on individual human feelings while appreciating the social context of the individual. According to him, an individual’s contribution to, and relations with family and society had a deep bearing on their sense of worth and overall personal development. This is also connected to the understanding of human motivation.

His work in the field introduced the term ‘inferiority feeling’, which is often now cited as an inferiority complex. Adler is also known for his work in exploring the influence of birth order on an individual’s development. For example, firstborns are inclined to be achievement-oriented, and leaders take up responsibility. Lastborns on the other hand may adopt behavioral tactics to attract attention. Adler’s work has had a significant impact on psychotherapy and counseling.

7. Erik Erikson

Erikson was a German-American psychologist best known for his groundbreaking theory of psychosocial development. He developed 8 stages of development, covering the lifespan of an individual. These stages are a predetermined order in which personality is developed, each presenting a set of challenges to be overcome. He is also associated with the development of the term ‘identity crises’, which signifies a period of deep introspection in a bid to realize a clear identity. Erikson also highlighted that ego had a role to play in one’s development and that a stronger ego was critical for one’s psychological wellness. His work has had a great influence on developmental psychology and psychotherapy.

Mary Calkins was the first woman to hold the position of President of the American Psychological Association.  She is credited for introducing the field of self-psychology, which entails a study of the individual’s subjective experience and identity. This, she held was critical in understanding human psychology. She is also known for her work in dream research and memory. Calkins was denied a Ph.D. by Harvard University in 1903 because she was a woman, despite being the first to complete the doctoral degree requirements. She however went on to become the first woman president of the American Psychological Association and the American Philosophical Association.

Jean Piaget was a Swiss psychologist best known for his theory of cognitive development in children. He introduced the idea that thought processes in children differ from those in adults. Previously, the two groups were not differentiated in psychology; children were understood as mini-adults. He emphasized the need for children to construct their knowledge through their active interaction with the environment. Piaget is also credited for developing the term genetic epistemology, which involves exploring the origins of knowledge. He established the International Center for Genetic Epistemology in 1955. His work has had an immense impact on child psychology and in the field of education.

10. William James

William James is known as the father of American psychology. He set up the first psychology department at Harvard, the first experimental psychology lab in the United States. He was the first to teach a psychology course in the country, hence the title ‘father of American psychology’.  He also wrote ‘The Principles of Psychology’.  It was published in 1890. William made important contributions to pragmatic psychology, an approach that focuses on the practical consequences of beliefs or ideas. He also introduced the concept of the ‘stream of consciousness’, which acknowledged the dynamism in human consciousness. His work continues to influence the understanding of the mind and human experience.

Skinner was an American psychologist and one of the key figures in the development of behavioral psychology. He is often considered the father of behaviorism, with particular influence in the area of behavior analysis and operant conditioning. The latter focuses on the effect of consequences on behavior. When a consequence is bad, it may deter repetition of the action, but when the same is good, the chances of repetition are higher. This is also known as the principle of reinforcement. Radical behaviorism was Skinner’s approach to psychology, with an emphasis on observable behavior rather than internal mental processes. His work has been influential in the study of behavior and its modification.

12. Elizabeth Loftus

Loftus is one of the key leading cognitive psychologists in the field today. She is best known for her groundbreaking work on the flexibility of human memory and eyewitness testimony. Her research on the misinformation effect establishes that memory can be altered when a person is fed misleading information after an event. How the person recalls the event can easily be tampered with by new information or how questions are phrased. Thus, eyewitness testimony is prone to the fallibility of human memory, and to an extent, the danger of false, distorted memories.

By using suggestive techniques, it’s possible to introduce false memories in an individual. Loftus has conducted several experiments to prove this. Her research and findings on eyewitness testimonies and their reliability have been used in the legal field. She has also received awards for her contributions to psychology. These include the American Psychological Association Award for Distinguished Scientific Contributions and the Association for Psychological Science (APS) William James Fellow Award.

13. Steven Pinker

Steven Pinker is a Canadian cognitive psychologist, known for his work in psycholinguistics, visual cognition, and understanding human nature. He is also a popular science author and has published several books. Some of his works include The Language Instinct (1994), Enlightenment Now (2018), The Blank Slate (2002), and The Better Angels of Our Nature (2011).

He’s researched the cognitive processes that inform the acquisition of language and its evolution, and the relation between language and expression of thought. He also posits that evolution shapes the human mind and behavior and that through reason and the application of knowledge, society can make positive progress. Pinker has received awards, including the American Psychological Association’s Lifetime Achievement Award, and the William James Book Award.

14. Daniel Kahneman

Kahneman is an Israeli-American psychologist and a Nobel Prize winner for his Prospect Theory of Decision Making in 2002. The theory challenges the rational choice theory and holds that decisions are influenced by subjective factors. He is best known for his contributions to the psychology of judgment and decision-making especially in the economic field. He has also published books, including the popular ‘Thinking, Fast and Slow’. He discusses his findings on cognitive systems and explores related themes on intuition, decision-making, biases, and general behavioral economics. His valuable research has had an impact on the fields of cognitive psychology and behavioral economics.

Bandura was a Canadian-American psychologist, known for his social cognitive theory. He advanced the position that people learn behavior from their environment. This is usually done by observing, imitating, and modeling. Some people, therefore, learn from observing others, and this interaction between individuals and their environment is critical in shaping human behavior. Bandura also developed the concept of self-efficacy, which illustrates that a person’s belief in their ability to perform bears an influence on motivation and resilience. His work has deepened our understanding of behavior and learning. Insights from his research have been employed in fields such as therapy and education.

The field of psychology continues to evolve, as further research reveals more about the human mind and behavior. These discoveries and theories have been critical in understanding human nature. Their application in other fields such as therapy, counseling, education, and economics continues to enrich and better the human experience. Psychologists committed to realizing answers to questions of the human mind have indeed greatly contributed to the successes made this far. As the human race continues to evolve, further research and discoveries in the field of psychology are far from over.
