Types of human behavior in psychology 


Human behavior is defined as the potential and expressed capacity (mentally, physically, and socially) of an individual or group to respond to the internal and external stimuli throughout their life. Human behavior can be simple to understand if we know their behavior in certain situations.


A study on human behavior has identified four basic types of personalities. This topic will help you understand the different types of human personalities. In order to understand the behavior of a person, we need to understand how that person will react if something happens.

Many of us evaluate a person’s behavior depending on the reaction he gives in different situations. When we approve or disapprove of any person’s behavior then it is called evaluating behavior. The major thing that defines behavior is the nature of a person and the nature of the situation he is faced with.

Classification of human behavior

Depending upon the different human reactions, human behavior can be divided into the following types.

Molecular and molar behavior

  • A sudden or rapid behavior that occurs without thinking is called molecular behavior like suddenly pulling back your hand when you get an electric shock or hit fire.
  • Molar behavior on the other hand is the one that occurs after thinking like changing your direction or way when you see an obstacle while walking or driving.

Overt and covert behavior

  • Overt behavior is a visible behavior that occurs outside of human beings like eating, playing or singing, etc.
  • Covert behavior is not visible. Thinking is a good example of this.

Voluntary and involuntary behavior

  • Voluntary behavior occurs when a human wants it like walking, writing or eating, etc.
  • Involuntary behavior occurs naturally or without thinking. Breathing or heart beating is a good example of it. 

Four types of personalities

A research study on human behavior has classified human personality into the following types.

  • Optimistic:

About 20% (not a much larger number) of people in this world are optimistic. Optimism is characterized as a mental attitude in which the person hopes for the best to happen even if it’s not likely. He stays very positive and strong in the hard times as well. They may get pessimistic at times but generally, they are very hopeful about life and succeed in life. They give the best of their abilities due to the positivity within them. 

  • Pessimistic:

This type of personality on the other hand is very less or not hopeful at all about life and things or people around them. Around 20% of people in the world are estimated to have this personality. They see everything in a negative way and mostly react negatively in any situation they are faced with. They generally tend to focus on the negative or according to some people a realistic view of life. They have a higher risk to attempt suicides when faced with any difficult situation.  

  • Trusting:

20% of people have this personality. These people trust others easily and they don’t need a reason to believe others. They depend on others for certain actions and desire to have the expected outcome. Trusting everyone may be a disaster at times when they rely on people who were not trustworthy.  

  • Envious:

According to research, 30% of people have this personality. It’s important to know that a single person may become optimistic, pessimistic, envious, and trust due to the fact that these traits exist in all human beings. The word envious is derived from the word envy which defines an emotional state in which a person desires to have any other person’s superior quality, achievement, or possession or wishes that he lacked it. They have a feeling of jealousy for others and may even make vicious plans to harm other’s success.

Understanding human behavior can be very helpful in handling different people when we know about the personality they have. The study of human behavior has played a vital role in improving the lives of people with behavioral disorders especially when it comes to your intimate relations.
