What is Psychology? 26 major branches of psychology

What is psychology?

Are you acquainted with the definition of psychology? Do you know what psychology is? Why do we procrastinate? Why don’t we avoid smoking and eating fattening food that makes us sick? Why do we shout at others and get easily angry? Why are we sometimes upset, but we struggle to find the reason? Psychologists’ attention draws to these questions. The science of Psychology closely connects to our everyday life. In this article, I will introduce this science’s definition, application, and branches in this article.

Etymology and symbol of psychology

The word psy+chology consists of two Greek words (ψυχολογία). It’s good to know that the word psyche (ψυχή) means soul, and it is not related to the words “mind and mentality.” However, the English language translates the word “psyche” into “mind” improperly.

The symbol of psychology is one of the Greek alphabets. This character is the 23rd letter of the Greek alphabet and is pronounced as “saai” (as in side).

The psychology symbol is the twenty-third letter in the Greek alphabet called Sai.

A comprehensive definition of psychology

Psychology is the scientific study of mental processes and behavior.
The definition mentioned above reveals three points about the essence of psychology.

  1. It is a scientific study.
  2. It studies behavior scientifically.
  3. It studies mental processes.

As mentioned, psychology is a scientific field. Consequently, it establishes scientific principles and follows them like other areas that study behavior (observable) and mental processes (subjective). Behavior is how, whereas cognitive processes are hidden and happen inside the mind.
As we have learned from the quiddity of psychology, psychology is knowledge. So, like other branches of knowledge, it follows scientific principles. This knowledge studies behavior that is visual (objective) and mental processes that are conceptual (subjective). Behavior is all the reactions that occur to people. Behavior is obvious, and the mental process is hidden.

Objectives of psychology

Science is purely objective, and scientists pursue those goals. The primary goals of psychology are:

1. Describe the behavior

2. Explain the behavior

3. Predict behavior

4. Control behavior

1. Describe

The first objective is to describe the behavior and mental processes in simple terms. Describing the behavior and cognitive functions makes it possible to evaluate and assess them and determine whether they are normal or abnormal. Psychologists use various descriptive methods, like naturalistic observation, case studies, correlational studies, surveys, and self-report inventories. They employ descriptive sentences and concepts to convey those theories and viewpoints based on hypotheses. So describing mental processes and behavior helps us understand the nature behind them, and as a result, we find answers to questions like “what is suicide?” or “what is aggression?”.

2. Explain

Psychologists explain behavior and mental processes after describing them; Describing behavior answers “what” questions. However, to answer “why” questions, the behavior needs to be explained. Telling issues like “aggression” and “suicide” helps us gain more profound knowledge about their nature, whereas to know why they appear, we need to explain them.

3. Prediction

The third goal is to predict behavior and mental processes. We should predict how people think in different situations and react to various stimuli. For instance, some people assume that watching violent scenes (like boxing and wrestling) reduces aggression. However, studies have shown that if 9-year-old are willing to watch violent scenes, they are more likely to show aggressive behavior compared to their peers when they are 18.

4. Control

The most crucial goal of psychology is to control behavior and mental processes. We can only prevent abnormal behavior and reinforce normal behavior if we control behavior and cognitive functions.

To conclude, psychologists seek answers to these questions:

  • What are we doing?” (describing)
  • “Why are we doing it?” (explaining)
  • “When do we act/respond/react in this way?” (predicting)
  • “How do we affect our lives and others by acting this way? How can we control our reaction to the environment? (controlling)
History of psychology

History

We can trace ideas and speculations about human nature and behavior back to the fifth century BC in Greece. Philosophers such as Socrates and Plato have asked various questions about human psychological life.[1] There have also been traces of this knowledge in Iran, China, India, and Egypt. Approaches such as cognitive, behavioral, and biological in psychology have their origins in the ideas of philosophers such as Plato, Socrates, Hippocrates, and others. It is no wonder there is a deep link between psychology and philosophy.

Most psychologists believe that the birth of psychology as a science occurred in 1879 when Wilhelm Wundt established the psychology laboratory in Leipzig-city, Germany.[2] He is well-known as the father of Experimental Psychology.
