mind and body intertwined
- evil spirits cause ailments
- treatments carried out by shamans (exorcism/prayer)
- making body uncomfortable for spirits (beating/starvation)
what is trephination?
hole drilled into the skull to let out evil spirits (lots of ppl survived)
what happened in ancient greece and rome?
origin of western medicine
- Plato: earliest to propose dualism
- MIND BODY PROBLEM: body as a physical being and mind as mental properties
who was hippocrates?
“father of medicine”
used clinical observations (like heartbeat) to examine a person for symptoms of illness
- proposed HUMORAL theory
-made the first hospital
what is the humoral theory of illness?
4 humours Blood (cheerfulness) Phlegm: (apathy) Yellow Bile (irritability) Black Bile (sad/depressive)
how do you treat excess humours?
diet, rest, baths, herbs, regulating environment, change of scenery
IN MIDDLE AGES: bloodletting and leaches
what did people believe before the humoral theory?
VIDEO Q
that gods were punishing the sick people!
who was Claudius Galen?
THEORY OF OPPOSITES (influenced by humoral theory)
scientific approach to medicine
- dissected animals and treated injuries of roman gladiators (discoveries about anatomy and localization of disease)
- hypothesis about the heart pumping blood throughout body
- supported by catholics
what did people think in the middle ages?
catholic church guarded medical knowledge
- supernatural explainations for illness , disease was punishment from god,
priests were physicians
bloodletting to balance humours
DISSECTIONS WEREN’T ALLOWED DURING THIS TIME
- exorcism (just like stone ages)
- torture to drive out spirits
- humors/bloodletting/leaches
- killing witches
- later on: penance through prayer and good works (to give back to make up for your evil spriti
what happened in the Renaissance?
dualistic (concept of mind and body)
Mind: theologians, priests, philosophers
Body: physicians (only used physical evidence to diagnose)
who was rene descartes?
Came up with “cartesian Dualism” = the mind and body are separate entities
- father of modern philosophy
- body works like a MACHINE that follows physical laws
allowed dissection on people again
what were some technological studies that separated mind from body?
Leeuwenhoek (bacteria, microscopic life
Morgagni (anatomical pathology via autopsies)
more labratory and less to mind
what is the germ theory of disease?
diesases are caused by specific micro-organisms
- biology as the sole cause of disease
- dualism
- reductionism
what is a reductionistic view?
searching for a ‘magic bullet’ cause for a disease
- pros: get to the main causes fast
- cons: doesn’t tell you how to get better or take in social determinates into account
what is the biomedical model and its strengths/limitations?
illness is due to bodily dysfunction.
focus on disease rather than wellness
mental/social factors irrelevant
PROS: led to vacines and antibiotics
- fewer deaths due to infectious diseases
- most prevalent cause of death are no longer to acute conditions
CONS:
- doesn’t recognize social/psychological influences
- illness rather than health promotion
- cannot explain puzzling medical observatoins
why are accidents going up ?
- transport accidents (cars/motorcycles)
- elderly people falling
- overdoses
how are patterns of illness changing and what are they changing to?
- acute to chronic conditions slow developing diseases cannot be cured/only managed health care costs rise quality of life decreases aging population crisis
who is sigmund freud?
founder of psychoanalysis
-CONVERSION HYSTERIA: unconcious conflicts converted into physical disturbances (if a person could convert this conflict into physical stuff they would be rid of the unconscious conflict
what is “glove anesthesia”?
the nerve affected in the hand SHOULD only affect half of the hand, but people report loss of sensation in the whole hand
- psychological explaination for this
what was the feild of early psychosomatic medicine like?
psychiatry and psychology
- medical problems believed to be caused by emotional conflicts
- ulcers, hyperthyroidism, arthritis, hypertension, colitis, asthma
conflicts lead to anxiety which produces a physiological effect via the autonomic nervous system
more of a biological side (finding biological mechanisms to explain mind/body connection)

helen flanders dunbar!
what type personality is a risk factor for heart disease?
A!
who was Franz Alexander?
developed the ‘ulcer prone’ personality
- neediness manifests itself as acid in the stomach which led to ulcers?
built on dunbar’s ideas
what are some critisisms of early psychosomatic medicine?
- simplistic
- not methodologically sound
- just didn’t have good research methods: hard to determine how valid a person’s statement is
-CURRENT STATE influences how they REMEMBER PAST experiences (i.e. childhood trauma etc.)
but it DID lay the groundwork for biopsychosocial model
what were the discoveries thoughout the 20th century?
30s-70s: stress on physiological systems (immunology)
70s: health psych and behavioral medicine emerged as fields.
representing physical health
today: active feild that has teaching/training and practice policy (to shape and improve care for society)
what are characteristics of the biopsychosocial model
macro and micro level processes
multiple factors influencing health/illness
mind and body are part of the same system
health and illness
compare the biomedical and biopsychosocial models
look in ur notes lecture 3
why is health psyc needed?
- patterns of disease are changing
- psych and social influences on health
diseases now take YEARS to develop, so there is a lot of opprotunity for change over someone’s life (health habits and whatnot)
biggest deaths: cancers/heart disease, other/accidents
what are health disparities?
socioeconomic status ethnicity/race gender sexual minorities rural/urban
what is the whitehall study?
michael marmot over 40 years studied the effect of job ranking and stress. lower class in your job makes you 3x as liekly to DIE its a stepwise/heirarchical positioning
what are health behaviors?
promoting behaviors
- physical activity
- fruit and veggie consumption
- sleep habits
- adherence to medical regimens
risk:
smoking, drinking, poor eating, obesity
how many canadians smoke?
almost 20% over the ages of 12
what has been found about the percentage of physically active canadians?
no interventions have worked, its the same physical activity over the years (2/10 adults and 1/10 kids getting enough exercise)
what is happening to our population?
its AGING
seniors will outnumber children
what is the definition of lonliness?
feelings of isolation, disconnectedness and not belonging
- ones desired and actual relationships
- not always the same as being alone
what is the theory of loneliness and health?
lonliness affects how you percieve and act which in turn affects your health
lonliness increases risk of early diesase, early mortality, poor health behaviors and the likelihood of being obese
- when someone is lonely they become attuned to threats in their environment and maybe even look for something negative i.e. thinking your partner is mad at you and then interpreting their words as aggressive
what is a theory?
set of ideas that provides framework for asking questions, gathering info and interpreting a phenomenon
whats a hypothesis?
specific predicitons about a phenomenon, based on a theory
replication is super duper important!
what is reliability vs. validity
reliability: consistency (precision) will the person get the same response under the same conditions
validity: measuring what you intend to measure (accuracy) are you measuring something else
what are the different types of experiments?
experimental - controlled - randomized correlation - cross sectional - longitudinal
whats an experiment to do with loneliness?
hypothesis: lonlier people will produce more inflammation when faced with a stressor.
134 participants and were given stressors (speech, mental math) and then had their blood drawn, lonely people were much more stressed in the task.
pros and cons of experimental methods?
pros
can draw casual conclusions
well controlled
- can manipulate stress well
cons
not always relevant to real life (i.e. in the stress test how often does your stress actually equal presentation o r mental math stress)
can’t always manipulate ind variables (age, sex, personality)
whats correlational methods?
relationships between variables (positive, negative) correlation coefficients
ideal for studying phenomena that can’t be manipulated for practical or ethical reasons
what is cross sectional research?
pros/cons?
a person is assessed once and comparisons are made between people
pros: less expensive, faster
cons: can’t determine cause and effect cause variables are measured at the same time/ so many 3rd variable issues
whats longitudinal research?
pros/cons?
same people assessed over more than one time (weeks/months/years)
naturally occuring experiences
predictors/consequences of events
pros: can determine order of evends
can examine changes across time within same ppl
cons: costly and time consuming biased sample (educated ppl signing up) attrition (dropouts) can't draw causal conclusions cant rule out confounding variables
whats an example of a londitudinal study that we talked about in class
loneliness will predict a greater risk of death across 6 years
1604 participants over 60 years of age
3 questions from the UCLA loneliness scale, death determined by family and national death index
FOUND: lonely adults had a greater risk of death over 6 years
