Experimental Psychology is a branch of psychology dedicated to the scientific study of human behavior and mental processes using experimental methods. It is concerned with understanding the processes underlying various forms of human behavior, both normal and abnormal, and involves creating rigorously controlled experimental environments to study behavior under specific conditions.
Origins of Experimental Psychology
Experimental psychology has its roots in the 19th century, when Wilhelm Wundt founded the first experimental psychology laboratory at the University of Leipzig, Germany, in 1879. Wundt is often referred to as the "father of experimental psychology" and is widely credited with establishing psychology as an independent academic discipline.
Research Methods in Experimental Psychology
Experimental Psychology utilizes a variety of research methods, including controlled experiments, observational studies, correlation studies, and case studies. Controlled experiments are perhaps the method most commonly associated with experimental psychology. In these experiments, researchers manipulate one or more independent variables and observe the effect on a dependent variable.
For example, an experimental psychologist might manipulate the amount of time participants spend studying (independent variable) and then measure their performance on a test (dependent variable). The goal is to determine whether there is a causal relationship between the two variables.
Areas of Study in Experimental Psychology
Experimental Psychology covers a wide range of areas of study, including cognition, perception, learning, memory, emotion, motivation, language, and more. In each of these areas, experimental psychologists seek to understand the underlying processes that guide our behavior.

For example, in the area of learning, experimental psychologists can study how people learn new information and skills, how reinforcement and punishment affect behavior, and how learning processes can be improved. In the area of cognition, they can study processes such as thinking, problem solving, decision making, and attention.
Contributions of Experimental Psychology
Experimental psychology has made significant contributions to our understanding of human behavior. It helped us understand how people learn, how we process information, how our emotions and motivations influence our behavior, and much more. In addition, the principles and methods of Experimental Psychology are applied in many other areas of psychology, such as clinical psychology, educational psychology, and organizational psychology.
In summary, Experimental Psychology is a fundamental area within psychology that is dedicated to the scientific study of human behavior and mental processes. Their findings have profound implications for our understanding of ourselves and others, and for how we live our lives.
