Anatomy and Physiology • Why is he in the r unning for father of modern psychology if he was wrong in so many ways? § He was wrong about many of his findings but he gave us ways to answer these questions § He gave us testable hypotheses, for when people disagree o Descartes Isnspiration • The automata inspired his theory of movement in nerves (NB nerve bundles known but not cells) § ** § ** • Reflexes § How our body responds to a stimulus o More Mechanical Descartes • Gave us "Testable" hypotheses! § Ex. Testing the nerve and muscles • A lot of movements are "non reflective " § Have their origins in senses which activate spirits • Animals as God's creations better than man made machines § No qualitative difference though § Animals do not have pineal glands (which was wrong) -- saying they didn't have a soul § Used animals for research • Dissected them while they were alive • He was amused by their screams; said their cries were mechanical • Believed if animals didn't have a soul, then they couldn't experience suffering o Jan Swammerdam • Spirits… I don't think so! § Didn't agree with Descartes-- so he tests it! • Tested Descartes theory of movement § Proved that spirits did not inflate the muscles § Cut muscle and found that it still contracts • Distinction between sensory and muscle nerves § Note: Group of researchers that fueled the quest for mechanization and quantification o Where do we get our inspiration from for current psychological research questions? • Think of this time in our history (guillotine era) --what is interesting to the public and great thinkers…? § Feeds into our quest in history f or understanding the body and mechanization/quantification • This was a public type of event that drew and interested people (brought children and popcorn) § 1905 Report reading of what this death looks like • "Undeniably living eyes which were looking at me" • People of this time are learning about the world around them by observing death in this way o Unzer • Was fascinated by the body in the same way • Reflexes § Discovered reflexes are Identical in decapitated and intact people and animals § Very interested in mechanization-- how the body works • Afferent and efferent § Nervous activity into and out of the nervous system • Studied the relationship between consciousness and nervous activity § Was all nervous activity contributing to consciousness? § Was it just high level activity generated by the brain? § What level of pain are we injecting up on someone with this method of death? o Juulien Offray De La Mettrie • "Thinking machine" (*cognitive psych, animals) • Determinist • L'Homme Machine § "Man a machine"-- we as humans are like ma chines (much like Descartes' mechanist point of view) § Origins in Descartes ideas -- deterministic evolutionary mechanistic point of view • Mental events depend on bodily events § Clarity of thought related to body temperature § Good physical health= good mental h ealth (ability to think clearly) § Brain injuries = mental debilitation (lucid thinking) • PTSD's effects on the brain • "The model of a 'thinking machine' into which sense perceptions feed ideas in the form of coded symbols that are in turn, stored, classed, c ompared, and combined by the cerebral apparatus in order to engender all the known varieties of thought" § Birth of cognitive psychology; hold this idea for 1950's psychology • He said there is No qualitative difference between man and animal § Yes, humans have language, but that's not enough to make us unique § Teaching apes to speak.. Why not? He said we could do that, so we are no better from animals § Hold this thought for 1960s -70s psychology: Comparative psychology • Comparing animal and man; we don't focus on th is type of psychology anymore • Mapping Central nervous system o Localization of Function Figures • Francois Magendie § Father of experimental physiology § Proved Charles bell's Theory… "the Bell -Magendie law" • Looking at afferent and efferent nervous system routes of the spinal column § Founder of experimental pharmacology § Previous way of knowing was through other people, but in 1817, we had books, ways of knowing on different syjects § 1817: Précis elementaire de physiologique (intro to p hysiology) • Franz Joseph Gall § "…gave psychology its most extreme theory of localization of function" § Personality and intelligence traits localized in particular areas of the brain § Ideas about phrenology offensive to religious and political authority § Folk psychology at its worst… pseudoscience § Phrenology: Extreme localization of function to the head § "You ought to have your head examined" § A second look at phrenology: Video clip • 1800s phrenology originated • Phrenology= assessing the person based on the structure of their skull • People divided into 4 body types: nervous, brillius, sanguine, and lymphatic • The mind is not a single entity; divided into 37 faculties • The size of the different mental faculties are proportionate to that aspect playing into a person's pers onality • By feeling the bumps on the skull, can tell if someone is prone to certain trait • Behavior truly influenced the health of the mind • Phrenologists emphasized fresh air and exercise to benefit the mind and your well being • Neuroplasticity= phenomenon that brain can change its structure based on experience • The components of the brain are not static -Gall • Different parts of the brain controlled/facilitated different mental pocesseses -- Gal was the first to think of this • Phrenology = "Science of the mind" § With changing cognitions, we can change our makeup. PSY 401 Lecture 12: Mechanization & Quantification Thursday, September 29, 2016 12:33 PM • Review from Tuesday o Quantification: observation of the person; a stimulus that caused an observable event • Ex. The guillotine o Phrenology: Looking at structural features of the soul rather than the brain • Having distinct localizations of human behaviors and traits • Critics to Phrenology o Pierre Flourens • AGAINST phrenology! • Supporting localization of function?...respiratory function in the Medulla Oblongata § Cerebrum higher level cognitive function a nd perceptions • He said Not really-- the brain functions as a whole § Highly interconnected networks § There is some localization of function, but for the most part, the brain is highly interconnected • Plasticity o Paul Broca • We do actually have at least some localization! (not phrenology) • Broca's area-- areas of the brain control speech production and speaking are localized in the brain • Mental institute patient *Tan • Fluid filled area of the brain o Carl Wernicke • Superior portion of the left temporal lobe interferes with speech comprehension • They could speak but not understand language § Following damage, can understand one component of speech or language (i.e. the word) but not understand production § How they discovered more localized areas • New Methods o Advancement through better methodologies • Observing and Measuring o Fritsch & Hitzig • Pioneers in electrophysiology § How stimulations effect specific functions of the brain § Sensitivity to specific areas on the brain • Using dogs stimulated one side of the cortex • Measured response in the opposite side of the body • Methods developed influenced evolution of psychology as a discipline! o Jaques Quetelet • One of the most underestimated figures in psychology • Relationship between age and criminal activity… • Statistics! § Normal bell curve § Standard deviation § Data is important, but it's your interpretation of what you're discovering that matters • "Average man" § There is a predecessor associated with each behavior relevant to the judicial system • Developed the BMI scale • Influenced Florence Nightengale § Major reformer and statistician § Developed figures and ways to visualize statistics that were being found at the time • Ways to interpret data from the bell curve that was being commonly used o Do we rely too heavily on quantitative measuremen t in 2016? • How do we measure the big picture? o Sir Francis Galton • Considered to be a child prodigy § Learned to read by age 2, understood greek and latin by 5 • Proposed a connection between genius and insanity (during nervous breakdown at university) § Hereditary genius (1869) § People's hereditary genius interferes with their mental disorders (i.e., insanity) which effects their day to day life • Obsession with counting • "Statistical inquiries into the Effectiveness of Prayer" (1872) • Co-relations and their measurements (1888) • Eugenics • First to use questionnaire in psychology • He doesn't fit the trait of the "average man" § The way he navigated the world and viewed others then made it easy for him to be above others or treat people as lower because he was a prodigy § He had a very rigid framework for what was good/bad in the world and what was success/failure • When he viewed other cultures, races, etc. he had a clear easy definition for what was superior and inferior in comparison • "There is no body or mental attribu te… Which cannot be gripped and consolidated into an ogive with a smooth outline" • Attempt to rationalize prejudice by self-fulfilling prophecies § If he had a different objectivity to what was viewed, he made the occurence of the world fit to what he wanted to hear/see • This approach is non-objective; we must look at objectivity in a different way § Have an approach that fits every subject of the population to make the method reliable § Cannot be defined by personal opinion § Must have a dependent variable § We need replication in science
