The birth of experimental psychology started with a few important experiments that changed the way we understand the mind. Let’s look at some key moments from the late 19th century that were important for this field.
Wilhelm Wundt's Laboratory: Wilhelm Wundt is often called the "father of experimental psychology." In 1879, he opened the first psychological lab in Leipzig, Germany. Wundt wanted to study how the mind works by running careful experiments. He used a method called introspection, where trained people would describe what they felt or experienced when they were given certain stimuli. For instance, someone might have to say what they felt after seeing a bright light or hearing a sound. This was a big change from just thinking about the mind from a philosophical angle to actually studying it scientifically.
Psychophysical Experiments: Wundt had peers like Gustav Fechner who also made important contributions. Fechner worked on psychophysics, which looks at how the physical world affects our feelings and sensations. He created methods to measure how changes in stimuli affect what we sense. For example, he introduced the idea of the "just-noticeable difference" (JND). This means figuring out how much something has to change for a person to notice it. Imagine you have a 100g weight; a person might only notice an increase when it reaches 102g. This helped scientists measure how we perceive things.
Ebbinghaus and Memory: Hermann Ebbinghaus did important experiments on memory in the 1880s. He used nonsense syllables to study how we memorize and recall information without relying on what we already know. His work led to the finding known as the "forgetting curve." This idea shows how fast we forget new information over time, which is still a key idea in understanding how our minds work today.
These early studies built a strong base for experimental psychology. They showed that we could use scientific methods to learn about how people think and act. This encouraged future psychologists to study the mind in a more scientific way, turning psychology into a proper science.
