History and philosophical foundations of psychology (lecture 2 and 3)
Zeitgeist - dominant set of ideals and beliefs that motivate actions of members of society at a
particular period of time
• e.g. computer code = good day to look at brain code
• Neurons considered to be firing or quiet (ie on=1 or off=0)
• Wilhelm Wundt (1832-1920)
• Established first psychological lab
• Considered start of scientific psychology
• Trepanation
• Stone age
• Hole in head
• Edwin Smith Papyrus
• Confusion about the soul and where the brain functions were located
• Showed at one point Egyptians did know about brain functions
• More concerned with the seat of the soul
• Heart was considered seat of the soul
• Feelings, thinking came from the heart
• Studies head wounds of soldiers, brain lesions lead to distal symptoms
• Left side controls right side and vice versa, brain responsible for speech
• Found specific functions are localised in the brain
• Discovery of ventricles
• 3 rooms in the brain
• 3 cell doctrine
• One room was receiver for sensory input
• One room working/short term memory
• One room long term memory
• Lateral ventricle (left and right)
• 3rd in centre
• 4th (discovered later)
• Phrenology
• Gall and Spurzheim
• Feeling for bumps in head which indicate what you're better at
• Localised functions of brain

Document Summary
History and philosophical foundations of psychology (lecture 2 and 3) Studies head wounds of soldiers, brain lesions lead to distal symptoms. Left side controls right side and vice versa, brain responsible for speech. Lateral ventricle (left and right: phrenology, gall and spurzheim. Feeling for bumps in head which indicate what you"re better at. Localised functions of brain: examples of localised functions, phineas gage - pole through head, paul broca and patient tan (understands but can"t talk, only says tan, karl wernicke and patient (doesn"t understand but can talk, language comprehension. Lobotomy absent: plasticity - will help young patients, but removing half of brain will not make you a happy person. Look at functional brain areas using fmri (functional magnetic resonance imaging) Scans: today, neuro-imaging, can be criticised as modern day phrenology, view highly specialised areas as part of a massive network.
