Wundt's approach to study the structure of the human mind, by breaking down behaviours into their basic elements. He concentrated on 3 areas: thoughts, images and feelings.
Wundts method of investigation the human mind. PPS were shown a ticking metronome and reported what the stimulus made them think and feel. The same stimulus, physical surroundings and instructions were given to each person.
He showed psychology could be a valid experimental science His lab-based method led to alignment with psychology as a science. He created lab experiment and controlled experiments.
Introspection relies on non-observable responses. Thoughts cant be measured as we don't know who is telling the truth. And participants cant report unconscious thoughts, meaning it is not scientific.
Griffiths (1994) used introspection to study cognitive processes of fruit machines gamblers. He asked them to think aloud whilst playing. Finding addicts has different cognitions to non addicts.
Focused on highly controlled lab experiments which could be replicated. Measuring concepts empirically and found a way to test objectively (behavioural approach)
