In what way was Wundt and Titchener's approach of structuralism an attempt to imitate chemistry and physics?

Wundt and Titchener's approach of structuralism attempted to impersonate chemistry and physics with how tries were directed. A case of this is a subject would be secluded from the researchers and they would be presented to some type of jolt (light, solid, and so on); the subject would then respond to the boost by pushing a catch and a response time would be recorded. Wundt could quantify response times as close as to one-thousandth of a second.
