Wilhelm Wundt = 'father of psychology', founded the first psychology lab in 1879 in Leipzig, Germany.
His approach was structuralism which breaks down behaviour into basic elements to study the structure of human mind.
He used introspection - looking to, whilst investigating were asked to reflect and describe their cognitive processes. Pps would be presented with a problem or something to memorise and then asked to report on their inner experiences. This was obtained during task performance to ensure no memory problems. This was the 1st experimental attempt to study the brain.
