Inferences were able to be made and the mind was compared to a computer, such as the MSM and used experiments to test theories, increasing validity and binding it to be a scientific discipline.
• 1980s: Biological Approach


  Advancements in technology allowed investigations into processes by examining live brain activity, such as fMRIs and, more recently, relationships between genes and behaviour.
