Free online courseIntroduction to Psychology

Course Description

Understanding why people think, feel, and act the way they do is a practical skill—useful in healthcare, education, business, and everyday relationships. This free online Introduction to Psychology course gives you a clear, science-based framework for making sense of human behavior, from the biology of the brain to the social forces that shape decisions. If you are considering a future in health or simply want a better grasp of yourself and others, you will gain tools to interpret real situations with more accuracy and empathy.

You will explore how psychology developed as a field and how researchers investigate the mind through careful observation, experiments, and ethical study design. The course connects big questions to evidence: how neurotransmitters influence mood and motivation, how different brain areas support survival and higher reasoning, and how development begins even before birth. You will also examine sensation and perception—how the world reaches the brain, and why what we notice is not always the same as what is there.

As you move forward, you will learn how consciousness and biological rhythms affect attention, sleep, and performance, and why these patterns matter for mental well-being. You will also build a practical understanding of learning through classical and operant conditioning—knowledge that helps explain habits, motivation, and behavior change in real life. Memory and emotion are covered in ways that highlight common experiences such as déjà vu, stress reactions, and the link between thoughts, feelings, and the body.

The course introduces key perspectives on personality and provides an accessible entry into psychological disorders and therapy, focusing on how symptoms are understood, categorized, and treated. You will also examine stress and health, including how long-term strain can influence the body, and you will finish with insights from social psychology—how we explain other people’s actions and how judgment can be biased. Short exercises throughout help you check your understanding, strengthen recall, and turn concepts into usable knowledge you can apply beyond the screen.
