The cognitive approach began to revolutionize psychology in the late 1950’s and early 1960’s, to become the dominant approach (i.e. perspective) in psychology by the late 1970s. But it was the arrival of the computer that gave cognitive psychology the terminology and metaphor it needed to investigate the human mind. The start of the use of computers allowed psychologists to try to understand the complexities of human cognition by comparing it with something simpler and better understood i.e. an artificial system such as a computer. http://www.youtube.com/watch?v=AeoyzqmyWug In order to understand the mind – both conscious and unconscious thought – one has to understand the brain and how it works.

Gage (1823–1860) was an American railroad construction foreman remembered for his improbable survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe … and for that injury's reported effects on his personality and behavior over the remaining twelve years of his life effects so profound that (for a time at least) friends saw him as "no longer Gage." http://www.youtube.com/watch?v=c6kRP41ygrI The frontal lobe and it’s parts are also responsible for the way we perceive things. In 1953, an anonymous patient by the name of HM underwent one of the most drastic and educational surgeries that neuroscientists and psychologists had ever seen. The surgery was performed in an attempt to cure his epilepsy. Doctor Scoville removed a section of HM's brain encompassing the hippocampus. HM lost the ability to form new memories. He would have a conversation with someone new … and moments after meeting, would be quite unaware that the conversation had taken place. He became suspended in time on that surgical day.
