Unformatted text preview: Midterm 1 Outline 1:- Biopsychology – studying the biological basis of behavior o How the nervous system works o Behavior in psychology began with the greeks- Hipocretes – early greek physican o Had the idea that the brain was a physical entity that contolled behavior Called monism ( brain is like the body and not the a magical entity) • No way to prove it o Went against the idea that spirit controls behavior- Aristotle o Belivevd the mind was different from the brain o Believed the brain controls the body and the mind/soul does not live in the brain o Dualism – seperation between the mind and the brain o Emotions = mind o Physical changes = brain- Descartes – 17 th century French philosopher o Accepted/expanded dualism o One of the first to try and understand human behavior scientifically o Proposed the mechanical model ( hydrolic ) Our body was hydrolic fluids and we when the fluids shifted, we moved o Tried to explain how the brain and mind interact and that we move our bodies because we use our minds o The mind monitored the brain and made decisions o Pineal gland – was manipulated/shifted to produce body movements (like a joystick)- Luigi Galvani – italian physiologist o Discovered that muscle contractions were from electrical contractions o Tested hydrolics model and isolated specific body parts o Decided to play with electrical impulse to see if he could get a contraction from it- Johannes Muller – german physiolgist o Accepted that electric caused movement, but it was not understood where the electrical current came from o Performed experimental ablation – surgically remove parts of the brain/body and see what happens to the body o Determined that the same level of charge = same level of contraction o Defined Doctrine of Specific Nerve Energies – nerves carry the same basic message The reason we produce differernt behaviors is because the brain is functionally divided, not because the electrical impulse is different One part of the brain stimulates a specific behavior - Pierre Flourens – o continued using ablation technique o systematically tried to map out the brain o determined/documented which parts of the brain contolled specific behavior o used mice brains by damaging parts of it and once it was recovered, recorded how the behavior was effected o behaviors overlapped with different parts of the brain- Paul Broca – first to study human behavior and brain functioning o was a doctor o studied brains after patients died beacsue he was referred a patient who had a stroke and could not talk (“Tan-Tan”), but could do everything else After Tan-Tan’s death, he found a lecision the size of a golfball on the back frontal/front temporal lobe (Broca’s Area) Studied 9 people with the same damage as Tan-Tan after he died - Case study - case study methods involve an in-depth, longitudinal examination of a single instance or event: a case.
