Step-by-step explanation:
Structuralism is a school of thought in psychology that focused on understanding mental processes by analyzing their individual components. It emphasized the contents of mental processes rather than their function. With structuralism, psychologists believed that by breaking down experiences into their basic elements through introspection, they could gain a better understanding of the mind.
The pioneer of the structuralist approach was Wilhelm Wundt. In 1879, Wundt established the first psychology laboratory at the University of Leipzig and conducted experiments on reaction times in a controlled setting. His work paved the way for the development of structuralism as a major school of thought in psychology.
