What is Psychology

Psychology is the scientific study of the human mind and behaviour. It helps us understand how people think, feel and act in different situations. Psychologists use scientific methods such as observation, experiments and data analysis to learn why individuals behave the way they do. The field covers many areas, including the brain, emotions, relationships, learning and mental health, making it essential for understanding human life and improving wellbeing.

History of Psychology

Now let’s have a look at the overview of the History of Psychology in these three major schools:

a) Behaviourism

b) Humanism

c) Cognitive theory

Behaviourism

Behaviourism thrived in the United States at the beginning of the 1930s. B.F. Skinner was setting the pace in exhibiting the power of operant conditioning with reinforcement. Skinner and his followers plainly excluded mental life, seeing the human mind as an unbreakable “black box” which is open only to conjecture and speculative fiction.

Their work explained that social behaviour is easily affected by manipulating certain unforeseen circumstances and by altering the outcomes and rewards. Similarly, varieties of emotions, whether positive or negative, may be obtained by the process of behaviour modifications and can be changed with the application of the same principles. Psychology Quotes from experts like Skinner illustrate the lasting impact of these ideas on how we understand human actions and reactions.

Humanism

Carl Rogers and Abraham Maslow did not agree with Psychoanalysis and Behaviourism. They considered that thoughts and actions are managed by free will and the capacity of an individual for development. Humanists give importance to emotions and think people are normally good.

The concept of this humanist approach shows that humans have an inherent desire to reach personal fulfilment or become the best version of themselves. According to humanists, reaching this level is not an easy task, and there are various other factors, such as psychosocial needs, that an individual must take into consideration before chasing personal fulfilment.

Cognitive theory

The Cognitive approach began gaining influence during the 1950s and 1960s, marking what is known as the Cognitive Revolution. Cognitive theorists believe that people process information from their environment through perception, memory, reasoning and problem-solving.

This theory explains how we receive, store, retrieve and interpret information, showing how mental processes guide decision-making, learning and behaviour.

Different Types of Psychology

Major Types of Psychology refer to the distinct areas or subfields within the discipline that focus on specific aspects of Human Behaviour, cognition, and Mental Processes. These branches represent specialised areas of study and research that contribute to our understanding of the complexities of the human mind.

Each branch emphasises different aspects of Human Behaviour, such as Mental Health, cognition, growth and development, social interactions, and the influence of various factors. Studying these branches allows researchers and practitioners to gain insights into specific domains of Human Psychology and apply their knowledge to various practical and theoretical contexts. Some of the major Types of Psychology are as follows:
