Psychology: Historical Backgroud, Definitions, Branches, Theories & Schools Of Psychology
Psychology is the scientific study of the mind and behavior. It is a multifaceted discipline that seeks to understand the complex relationships between the brain, the environment, and behavior. The origins of psychology can be traced back to ancient civilizations, but the modern field of psychology as we know it today began to take shape in the 19th century.
One of the earliest recorded accounts of psychology is found in the ancient civilizations of Egypt and Greece. In these societies, people believed that the gods and goddesses controlled human behavior and that certain rituals and offerings could influence their behavior. In the Middle Ages, psychology was largely seen as a branch of philosophy, and philosophers such as Rene Descartes and John Locke made significant contributions to the field.
It was not until the 19th century, however, that psychology began to emerge as a distinct scientific discipline. In the late 1800s, Wilhelm Wundt established the first laboratory specifically dedicated to the study of psychology at the University of Leipzig in Germany. Wundt is often referred to as the "father of psychology" because of his contributions to the field.
Since then, psychology has grown and evolved into a complex and diverse discipline that encompasses a wide range of subfields and approaches. Today, psychologists use a variety of research methods, including experiments, observations, and surveys, to study a wide range of topics, including perception, cognition, emotion, development, personality, and social behavior.
There are several branches of psychology, each focusing on different aspects of human behavior and mental processes. Some of the major branches of psychology include:
2. Cognitive psychology: This branch studies mental processes such as perception, attention, language, memory, and decision-making.
3. Developmental psychology: This branch studies how people change and grow throughout the lifespan, including physical, cognitive, social, and emotional development.
4. Social psychology: This branch studies how people think, feel, and behave in social situations and how they are influenced by others.
5. Industrial-organizational psychology: This branch applies psychological principles to the workplace, including topics such as personnel selection, training, and leadership.
6. Educational psychology: This branch focuses on how people learn and how to improve teaching and learning processes in educational settings.
7. Forensic psychology: This branch applies psychological principles to the legal system, including topics such as eyewitness testimony and criminal responsibility.
8. Health psychology: This branch focuses on how psychological, social, and cultural factors influence physical health and illness.
Psychological variables are any factors that can influence a person's thoughts, feelings, or behaviors. These can include personal characteristics, such as age, gender, personality, and intelligence, as well as environmental factors, such as cultural influences, family dynamics, and social norms. Psychological variables are important to consider in psychology research, as they can help to explain why people behave the way they do and how they respond to different situations. Understanding psychological variables can also be useful in clinical settings, as it can help mental health professionals to identify potential contributing factors to a person's mental health issues and design treatment plans accordingly.
There are several schools of psychology, each with its own distinct approach to understanding the human mind and behavior. Some of the major schools of psychology include:
1. Structuralism: This school of psychology, founded by Wilhelm Wundt and Edward Titchener, focuses on breaking down mental processes into their smallest parts, called elements. Structuralists believed that understanding the structure of the mind could be achieved through introspection, or self-examination of one's own thoughts and feelings.
2. Functionalism: This school of psychology, founded by William James, focuses on the function or purpose of behavior and mental processes. Functionalists believed that behavior and mental processes could be understood by looking at their role in helping an organism adapt to its environment.
3. Psychoanalysis: This school of psychology, founded by Sigmund Freud, focuses on the role of the unconscious mind in shaping behavior and mental processes. Psychoanalysis emphasizes the use of techniques such as dream analysis and free association to explore the unconscious mind.
4. Behaviourism: This school of psychology, founded by John B. Watson and B.F. Skinner, focuses on the study of observable behavior and the role of environmental stimuli in shaping behavior. Behaviourists believe that behavior can be understood and changed through the use of reinforcement and punishment.
5. Humanistic psychology: This school of psychology, founded by Abraham Maslow and Carl Rogers, focuses on the individual's potential for personal growth and self-actualization. Humanistic psychologists believe that people are motivated by their inherent drive to reach their full potential and that this drive can be understood by looking at an individual's subjective experiences.
6. Cognitive psychology: This school of psychology focuses on the study of mental processes such as perception, attention, learning, and memory. Cognitive psychologists believe that understanding the mental processes involved in these behaviors can be achieved by studying how people process, store, and retrieve information.
7. Evolutionary psychology: This school of psychology focuses on the role of evolution in shaping behavior and mental processes. Evolutionary psychologists believe that behaviors and mental processes that have helped humans survive and reproduce in the past are more likely to be present in modern humans.
8. Cultural psychology: This school of psychology focuses on the role of culture in shaping behavior and mental processes. Cultural psychologists believe that behaviors and mental processes are influenced by the cultural context in which they occur.
There are number of psychological theories that have been developed to explain and understand human behavior and mental processes. Some of the major psychological theories include:
2. Behaviorism: This theory, developed by John B. Watson and B.F. Skinner, focuses on the role of environmental stimuli in shaping behavior. According to behaviorism, behavior is learned through reinforcement and punishment, and changes in behavior can be achieved by manipulating these stimuli.
3. Cognitive psychology: This theory focuses on the mental processes involved in perception, attention, learning, and memory. According to cognitive psychology, people process, store, and retrieve information in order to understand and navigate their environment.
4. Evolutionary psychology: This theory focuses on the role of evolution in shaping behavior and mental processes. According to evolutionary psychology, behaviors and mental processes that have helped humans survive and reproduce in the past are more likely to be present in modern humans.
5. Humanistic psychology: This theory, developed by Abraham Maslow and Carl Rogers, emphasizes the individual's potential for personal growth and self-actualization. According to humanistic psychology, people are motivated by their inherent drive to reach their full potential and can be understood by looking at their subjective experiences.
6. Social learning theory: This theory, developed by Albert Bandura, emphasizes the role of observation and imitation in shaping behavior. According to social learning theory, people learn new behaviors by observing others and then imitating those behaviors.
7. Biological psychology: This theory, also known as behavioral neuroscience or physiological psychology, focuses on the role of the brain and other biological processes in shaping behavior and mental processes. According to biological psychology, behaviors and mental processes are influenced by the activity of neurons and other cells in the nervous system
