False. Only Willhelm Wundt developed the viewpoint known as structuralism

 Structuralism was the first school of psychology and focused on breaking down mental processes into the most basic components. Researchers tried to understand the basic elements of consciousness using a method known as introspection. Wilhelm Wundt, founder of the first psychology lab, was an advocate of this position and is often considered the founder of structuralism, despite the fact that it was his student, Edward B. Titchener who first coined the term to describe this school of thought.

In response to structuralism, an American perspective emerged under the influence of thinkers such as Charles Darwin and William James. William James wrote that structuralism had "plenty of school, but no thought".  James opposed the structuralism focus on introspection and breaking down mental events to the smallest elements. Instead, James focused on the wholeness of an event, taking into the impact of the environment on behavior.
