Wilhelm Wundt founded the first psychology laboratory in 1879 and established structuralism as the first major school of thought in psychology. Structuralism aimed to analyze consciousness into its fundamental elements of sensations, perceptions, ideas, emotions, and analyze how these elements interacted and combined. A key aspect was the use of introspection to examine one's conscious experiences. Later, Titchener expanded on structuralism in the US but it fell out of favor due to subjective methods like introspection lacking reliability and observability.
