Experimental psychology is a branch of psychology that focuses on studying human behavior and mental processes through controlled and systematic experiments. It involves creating and manipulating independent variables to observe and measure the effects on dependent variables, such as perception, memory, learning, motivation, emotion, and cognition. The goal of experimental psychology is to gain a deeper understanding of psychological processes and develop theories to explain and predict human behavior.
History of Experimental Psychology
The history of experimental psychology can be traced back to the late 19th century when researchers began to use laboratory-based methods to study human behavior and mental processes.
One of the earliest pioneers of experimental psychology was Wilhelm Wundt, who established the first laboratory dedicated to psychology research at the University of Leipzig in Germany in 1879. Wundt believed that psychology should be studied scientifically, using methods such as introspection and controlled observation to gain a deeper understanding of the human mind.
In the United States, psychologist William James established the first experimental psychology laboratory at Harvard University in 1875. James’ work focused on the study of perception, emotion, and consciousness, and he is considered one of the founders of the functionalist school of psychology.
During the 20th century, experimental psychology continued to grow and diversify, with researchers exploring a wide range of topics, from learning and memory to perception and motivation. The advent of new technologies, such as brain imaging techniques and computer-based methods for conducting experiments, has also allowed researchers to gain new insights into the workings of the human mind.
Today, experimental psychology remains a thriving field, with researchers continuing to explore the complex interplay between cognition, behavior, and the brain.

Experimental techniques used in psychology include:
- Randomized controlled trials (RCTs): Participants are randomly assigned to either an experimental group or a control group. The experimental group receives the independent variable while the control group does not, allowing researchers to observe the effects of the independent variable on the dependent variable.
- Controlled observation: Researchers observe and measure the behavior of participants in a controlled environment while controlling for extraneous variables.
- Manipulation of independent variables: Researchers manipulate the independent variable to observe its effects on the dependent variable.
- Survey research: Participants are asked to complete a questionnaire or participate in an interview, which provides information about their attitudes, beliefs, and behaviors.
- Naturalistic observation: Researchers observe and measure behavior in natural settings, without manipulating the environment or the participants.
- Case studies: Researchers conduct a thorough investigation of an individual’s behavior, experiences, and history to gain a deeper understanding of a particular phenomenon.
- Neuroimaging techniques: Researchers use brain imaging techniques, such as functional magnetic resonance imaging (fMRI), to observe brain activity in response to specific stimuli.
These techniques allow researchers to gain a better understanding of the underlying psychological processes that contribute to human behavior and mental processes.

Experimental cognitive psychology is a highly interdisciplinary field that draws on knowledge from neuroscience, computer science, linguistics, and other fields to study human cognition and its underlying neural mechanisms.
Definition of experiment in psychology
In psychology, an experiment is a systematic and controlled study that is used to test a hypothesis about the relationship between variables. Experimentation typically involves the manipulation of an independent variable, with the effect on the dependent variable being measured. The goal of the experiment is to determine causality, meaning that the researcher wants to find out whether a change in the independent variable causes a change in the dependent variable.
In order to control for extraneous variables and to increase the internal validity of the experiment, participants are often randomly assigned to different conditions or groups. The results of the experiment can then be used to support or reject the hypothesis and to draw conclusions about the relationship between the variables. Experiments are a cornerstone of the scientific method and play a central role in the field of psychology, providing a way to test theories and understand the underlying causes of behavior and mental processes.
