In this blog, we’ll walk you through different types of psychology courses, their duration, what they cover, and how they can help shape your future career.
What is Psychology?
Psychology is the scientific study of the mind and behavior. Often referred to as the father of psychology, Wilhelm Wundt laid the foundation for psychology as a formal academic discipline.
According to the American Psychological Association (APA), psychology involves the systematic study and understanding of mental processes and behavioral patterns. While it primarily focuses on human thoughts, emotions, and actions, it also includes the study of animal behavior.
The term psychology comes from the Greek words “psyche” meaning mind or soul, and “logos” meaning study or science. Therefore, psychology is widely understood as the science of the mind or the science of the soul.
Psychology aims to understand why individuals think, feel, and act the way they do. To achieve this, the field operates around four key goals: Description, Explanation, Prediction, and Control of behavior.
Given its broad scope, psychology is divided into several branches, each focusing on specific aspects of mental and behavioral functioning.

The Branches of Psychology
Psychology is a vast area of study that is divided into different specializations, or branches, based on certain factors.
Let’s look at 10 major branches of Psychology and what they are-
Behavioral Psychology
Behavioral psychology or behaviorism is based on the approach of understanding the behavior of humans and animals. It works under the concept that environmental factors mold all behaviors. So the behaviors exhibited by an individual or an organism are a result of their conditioning.
Clinical Psychology
Clinical psychology deals with the study, diagnosis, and treatment of psychological disorders. A good deal of people get confused between clinical psychologists and psychiatrists. The main difference is a clinical psychologists can not prescribe medications and they do not have medical training. Hence, this field is more about understanding, observing, diagnosing, analyzing, and treating mental illnesses and behavioral disorders.
Cognitive Psychology
Cognitive psychology deals with the study of mental processes of perceiving, remembering, and thinking. It studies all aspects of cognition such as memory thinking, reasoning, language decision making, etc. This field also merges the applications of the cognitive psychology approach and cognitive neuroscience.
Developmental Psychology
Developmental psychology studies the growth of people throughout their lives. It analyses inter and intra-individual changes. Additionally, it analyzes how people grow and evolve from the moment of birth until they die.
Social Psychology
Social psychology studies how people’s thoughts, feelings, and actions are affected by others. It’s the branch of psychology that also deals with the behavior of people in a social setting. This includes studying group behavior, interactions, nonverbal communication, social thinking, community behavior, and social influence.
Educational Psychology
Educational psychology focuses on teaching and learning processes such as the relationship between intelligence and school performance. It is also concerned with how better teaching techniques can benefit both teachers and students. The main areas of work for educational psychologists include teacher training, curriculum planning, instruction design, and research and development.
Organizational Psychology
Organizational psychology applies psychology to solve the problems of industries and organizations. It does so through intelligence and aptitude tests of selected employees. Additionally, they apply psychology to problems of management and training to improve communication within the organization and help increase the overall employee performance.
Counselling Psychology
Counselling psychology focuses on our educational, social, and also career adjustment problems. For example, people with specific questions like career choices or educational programs will consult counselling psychologists.
Health Psychology
Health psychology explores the relationship between psychological factors and diseases. Good health and the ability to cope with illnesses are affected by psychological factors. Such as thoughts, emotions, and stress management. This is part of a growing field of Psychology, called psychoneuroimmunology. It focuses on the relationship between psychological factors and the immune system.
Environmental psychology
Environmental psychology is the study of our relationships with our environments. It explores how our environment affects our emotions. One way it does this, for example, is by considering the amount of stress we experience in a particular setting.

Psychological Disorders
Psychological disorders, also known as mental disorders, are clinical conditions that affect a person’s thoughts, emotions, behavior, and overall functioning. These disorders influence how individuals perceive the world and respond to everyday situations. The study, diagnosis, and treatment of these disorders form the foundation of psychology. Below are some of the major categories of psychological disorders:
Personality Disorders
Personality disorders involve unhealthy, rigid patterns of thinking, feeling, and behaving. Individuals with these disorders often struggle to relate to others, manage emotions, and function socially or professionally.
Personality disorders are grouped into three clusters:
Cluster A – Odd or Eccentric Behavior
Characterized by unusual or distorted thinking patterns.
Examples: Paranoid Personality Disorder, Schizoid Personality Disorder, Schizotypal Personality Disorder.
Cluster B — Dramatic, Emotional, or Erratic Behavior
Marked by intense emotions, impulsivity, and unpredictable actions.
Examples: Narcissistic Personality Disorder, Histrionic Personality Disorder, Borderline Personality Disorder, Antisocial Personality Disorder.
Cluster C — Anxious or Fearful Behavior
Associated with excessive fear or anxiety.
Examples: Obsessive-Compulsive Personality Disorder (OCPD), Avoidant Personality Disorder, Dependent Personality Disorder.
Note: OCPD is different from OCD.
Eating Disorders
Eating disorders involve an unhealthy preoccupation with food, body weight, and body shape. These disorders can become life-threatening if not treated promptly. Common symptoms include restricted food intake, binge eating, purging behaviors (vomiting or misuse of laxatives), and compulsive exercising.
Examples: Anorexia Nervosa, Binge Eating Disorder, Bulimia Nervosa.
Substance Use Disorders
Substance use disorders involve an uncontrollable urge to consume drugs or alcohol despite knowing their harmful effects. Individuals may use substances in large amounts, struggle with withdrawal symptoms, and develop tolerance—needing higher quantities to achieve the same effect. This disorder often disrupts work, relationships, and social functioning.
Mood Disorders
Mood disorders significantly affect a person’s emotional state. Individuals may experience extreme and prolonged mood shifts that do not align with their situation. These may include deep sadness, irritability, or episodes of elevated mood and hyperactivity known as mania. These mood changes can interfere with daily life, relationships, and behavior.
Examples: Bipolar Disorder, Major Depressive Disorder, Cyclothymic Disorder, Disruptive Mood Dysregulation Disorder.
Trauma and Stress-Related Disorders
These disorders develop after experiencing or witnessing traumatic or highly stressful events. Not everyone exposed to trauma develops a disorder; individual reactions vary based on experiences, resilience, and early-life stress. With timely treatment, most trauma-related disorders can be effectively managed.
Examples: Post-Traumatic Stress Disorder (PTSD), Reactive Attachment Disorder (RAD), Adjustment Disorder, Acute Stress Disorder (ASD).
