PRE-MID TERM Flashcards
what are the biology and evolutionary theories driven by?
-biology and internally
What are the 3 biological and evolutionary theories
- genetic and epigenetic interact with the environment to shape health/wellbeing
- genotype vs phenotype
- patterns of inheritance
explain genetic and epigenetic interact with the environment to shape health/wellbeing
genes control specific characteristics and we each have 23000 genes in each cell nucleus of our body
explain genotype vs phenotype
genotype is the specific genetic material on individual chromosomes whereas phenotype is the observed characteristic
explain patterns of inheritance
dominant-recessive pattern,
polygenic inheritance (many genes influence a trait)
multi-factorial inheritance (genes and environment)
mitochondrial inheritance (inherit genes from the mother’s egg)
What makes a good theory
- explain
- predict
- increases understanding
- testable
What is epigenetic?
study of changes stemming from modification of gene expression rather alteration of the genetic code
what are epigenetic markers
- they regulate gene expression by turning genes on or off
what happens when gene expression is controlled
epigenetic mechanisms regulate bodily processes
what are the 3 thing in epigenetics
- 100 year effect
- U shaped curve
what is the 100 year effect
- a theory that existed way before we were born
- it is an egg that was in ur mother when u were conceived and was in ur grandma was conceived, etc
environment of the grandma lived in shaped us, and it took 100 years to see the diff
what is the U shaped curve
way that babies enter the world matters: low birth weight vs high birth weight.
on one end of the curve there are heavy born babies and the other end are low birht weight and each end is an extreme so these babies will have chances of 3 or more chronic conditions
what is the average normal weight for a baby in canada
8lbs
what are pyschoanalytical theories
theories that say developmental change occurs because of influence of internal drives and emotions on behaviour
Who is an example of psychoanalytical theory
freud
What is the psychosexual theory and who did it
-freud
-behaviour is determined by conscious and unconscious processes
-libido is the sex drive
-personality structure has 3 parts (tripartite): id, ego and super ego
what is the id
- the pleasure principle
- driven by unconscious needs for pleasure
- displays itself as selfish and demands gratification
eg. a baby crying is driven by unconscious needs and once they get their milk, they get their pleasure.
- id is like the devil
when does ego develop
- develops around age of 2
what is the ego
-focuses on the reality principle
- mediates between id and super ego
what is the super ego
- morality principle
- it’s like an angel that stops from doing anything and will do it through guilt and punishes our ego
Freud’s theory was _____
super sexualized.
what did freud argue?
- that you have to go through all 5 stages/theories by resolving some type of conflict that exists otherwise you end up in fixation
what is the oral stage
- lasts from 0-2 years
- infants become happy through oral activities like feeding, thum sucking and babbling

smoking, overeating, passivity and gullibility
If you go through fixation, what happens in the anal stage?
orderliness, parsimonious, or the opposite
If you go through fixation, what happens in the Phallic stage?
Vanity, recklessness or the opposite
If you go through fixation, what happens in the latency stage?
nothing- fixation usually does not occur at this stage
If you go through fixation, what happens in the genital stage?
adults should have successfully integrated earlier stages and now should emerge with a sincere interest in other and mature sexuality
What is noticed about fixations?
- not testable
- predicting is lacking
Who was eric erikson?
- student of freud
what did erik erikson do?
- expanded freud’s theory by taking a life span approach

what are learning theories
they focus on how experiences in the ENVIRONMENT shape the child
how is human behaviour seen
as being shaped by processes such as classical and operant conditioning
How is Pavlov’s classical important?
plays an important role in the development of emotional responses
how is skinner’s operant important
extinction and shaping
What are advantages of learning theories
- testable
-predictive
-environmental context important
-why some people thrive and others dont
what are the disadvantages of learning theories
- very simplistic: that we can be controlled by our environment
- shaping children the way we grew
who came up with positive and neg reinforcement and pos and neg punishment
skinner and it is called opperant conditioning
what is positive punishment vs neg punishment
pos punishment you add something to punish (eg, timeout or hitting or a chore)
neg punishment you take away something to punish them (eg, the fav toy or their phone)
what is positive reinforcement vs neg reinforcement
pos: adding something to repeat that behaviour, eg: REWARD
neg: taking something away to repeat that behaviour:
eg, a kid does good on a test so to encourage him to do good you take a chore away and make his life easier.
what are the 4 types of operant conditioning
- pos reinforcement
- neg reinforcement
- pos punishment
- neg punishment
what are cognitive theories
they are emphasized mental aspects of development (eg, logic and memory)
eg of learning theories
- pavlov’s conditioning
- skinners operant conditioning
eg of pyschoanalytical theory
freud’s pyschosexual theory and erik erikson’s pyschosocial theory
What was piaget’s theory based on
scheme, assimilation, accommodation and equilibration
what is a scheme
an internal cognitive structure that provides an individual with procedure to follow in a specific circumstance
eg. how we brush our teeth: we plan it out as, first do this and then do that, etc
what is assimilation
process of applying schemes to (different?) experiences
eg. if a scheme was to get ready in the morning to come to class, but the same scheme could be applied to another class
what is accomodation
changing the scheme as a result of new information
eg. kids go through many spurts of development like learning a bunch of new words. when learning a new word they think on how to think or say a word and when they get feedback they retry it and change it
what is equiliberation
process of balancing assimilation and accomodation to create schemes that fit the environment
we learn what works and what doesn’t in particular situations.
what is the information processing theory
use the computer as a model of human thinking with memory processes
what is vgotsky’s theory
socio-cultural theory asserts complex forms of thinking- have their origins in social interactions
what is bandura’s theory
learning does not always require reinforcement, sometimes we learn through observation
How many stages does piaget stages of cognitive development have
4 stages
first stage of piaget’s cognitive development and explain
sensorimotor
- 0-2 years old
- coordination of senses with motor responses, sensory curiosity about the world. language used for demands and cataloguing. object permanence is developed
what is object permenance
understanding that items and people still exist even when you can’t see or hear them
eg, a baby sees a teddy bear
second stage of piaget’s cognitive development and explain
preoperational
- 2-7 years old
- symbolic thinking, using proper grammar to express concepts
- imagination and intuition are strong but complex abstract thoughts are still difficult
conversation is developed
third stage of piaget’s cognitive development and explain
concrete operational
- 7-11
- concepts attached to concrete situations
-time, space and quantity are understood and can be applied but not as independent concepts
fourth stage of piaget’s cognitive development and explain
formal operation
- 11 years and older
- theoretical, hypothetical and counterfactual thinking. abstract logic and reasoning, strategy and planning become possible
concepts learning in one context can be applied to another
what is bandura’s theory?
bridge between behaviourist and cognitive learning theories emphasis on attention, memory and motivation
he says you can learn through observation, limitation and modeling
an eg of bandura’s theory
influencing one another and influenced by environment; observing
eg. driving- looking at parents and also learning by the environment like stop signs etc.
eg. manners, for eg eye contact is important bc u look at ur parents to learn that.
are cognitive theories good?
yes bc it takes into account of environment and is combining it with biology
why can cognitive theories be bad?
difficult to test and observe
what is a systems theory
personal and external factors form a dynamic integrated system
basically everything interacting with everything
what two terms are part of the systems theory
holism and wellness
what doe holism mean
the “whole” is primary and often greater than the sum of its parts
what does wellness mean
a result of adaptive adjusment
this is the first group of theories to say something..what is it?
said studying a person in a lab is useless bc they don’t live in a lab and so need to study their environment along with the person
what is the bronfenbrenner bioecological system theory
development that is explained in terms of the relationships between people and their environments or contexts
what is the classification meaning in the bronfenbrenner bioecological system theory
classifies all the individual and contexual variables that affect development and specifies how they interact
what does bronfenbrenner bioecological system consist of (in order)
microsystem
mesosystem
exosystem
macrosystem
chronosystem
what is the microsystem
activities and interaction in the child’s IMMEDIATE surroundings
eg: parents, school, friends, etc
eg: interaction with roomates
what is the mesosystem
relationships AMONG entities invilved in child’s microsystem
eg: parent interaction with teachers, a school’s interaction with the daycare provider,
eg: prof at western
what is the exosystem
social instituitons which affect children indirectly
eg: parents’ work settings and policies, extended family networks, mass media, community resources
eg: western uni as a WHOLE, a job (organization)
what is the macrosystem
broader cultural values, laws and governmental resources
eg: the bus system, tuition freezes
what is the chronosystem
changes which occur during child’s life, both personally and culturally
eg: eg sibling birth (personal), Iraqi war (cultural), divorce, natural disaster, moving houses, gaining or losing a pet, 9/11, SAG strike, etc
what is a noticeable factor about all the theorists?
- all men
-all old
-all white
why is this a problem that all theoriests are white old men
- less diversity bc they only experience so much in relation to culture, etc
basically that these theories might only work with white old men
why do we still use these theories presented by these white old men
bc they laid the foundation for greater studies
What is a developmental trajectory that began before we even were a thought
100 year effect
what is the first stage in the developmental trajectory
conception
is the age of conception in canada getting higher or lower
higher
how much did the rates of triplets, quadruplets, and quintuples, increase since the mid 1990s
230% which is a lot
what is AMA
advance maternal age
Is AMA becoming an increasingly common phenomena?
yes
What is the AMA age
over 35
What does increased AMA lead to
- conception of multiple births
- increase in use of assisted human reproductive techniques
what are some examples of assisted human reproductive techniques
- fertility drugs
- cryopreservation: freezes the embryos created in IVF
- artificial insemination: injects sperm directly into the woman’s uterus
what are the 3 stages in pregnancy and prenatal development
antenatal: conception to post partum
preggo: physical condition in which a woman’s body is nurturing a developing embryo or fetus for 40 weeks
prenatal: process that transforms a zygote into a newborn
the first trimester
from the zygote implantation to 12 weeks is the first trimester
the second trimester
- 12 to 24 weeks
- begin to feel the fetus moving
third trimester
- 25+ weeks
- increased emotional attached to the fetus
what are the key issues in trimesters
- ectopic pregnancy: occurs when a fertilized egg implants and grows outside the main cavity of the uterus and usually occurs in the fallopian tube
- abnormal urine or blood tests
- increased blood pressure
-malnutrition
-bleeding
-miscarriage
why is malnutrition a first trimester issue in canada
- food insecurity
but it’s still a issue in SES people too
-its bc you throw up everything, no food is retained long enough therefore no nutrients are absorbed.
what are the key issues in the second trimester
- increased blood pressure
- bleeding
-premature labour - bladder infection: this starts of asymptomatic
- toxemia: blood poisoning by toxins from a local bacteria infection and the only cure is to delivery. it is another form of preeclampsia
What is the current trend and issue with the age of viability
age of viability is getting younfer and survival rate is getting higher
but bc of this, we have children with complex care condition and needing precision medicine and children living on technical wires
What are the issues in prenatal development
- genetic disorders
- chromosomal errors/ differences
- teratogens
what are genetic disorders
- autosomal dominant disorders (huntington’s disease, extra fingers)
- autosomal recessive disorders (sickle cell, cystic fibrosis)
- sex-linked recessive disorders (red-green colour blindess, missing front teeth)
what are chromosomal errors/differences
- trisomy (three copies- down syndrome)
- anomalies with sex chromosomes (turner’s syndrome)
what are teratogens
agents causing damage to the fetus bc it was exposed by mom
greatest risk in the first 8 weeks bc fetus has mass development
eg of teratogens: alc, drugs, caffeine, STDs, radiation, air, pollution, weed, etc
what are the issues with preterm birth
life long effects such as: cerebral palsy, cognitive impairment, visual and hearing impairment, poor health and growth and behavioural and social-emotional problems
how is age measured when a baby is a preemie
during the first 2 years of life, they record the actual age and the preterm age. this is bc the effect is so much during the first 2 years and some kids are fine after these 2 years and some aren’t
what is the normal birth weight in general and in canada
general: 5lbs to 8.13 lbs
canada: 8lbs 7oz
what is the low birth weight
5lbs 5oz
what is very low birth weight
less than 3.9 lbs
what is extremely low birth weight
less than 2.3 lbs
what is the cure for gestational diabetes
excerise and diet
what is the impact on the baby if mom has gestational diabetes
baby come`s out chunkier
what is the impact of low birth weight and very low birth weight
neg effects on mental and motor development and growth at 9 months to 2 years of age
effect on physical and mental development seems to lessen over time but the growth effects do not
what are the 2 options for birth location in london
- hospital: (OB or mid wife)
- home birth: (midwives)
Is home birth safe and who does it
- 9% of first time moms plan a home birth and 21% second times moms
- but only offered to women with NO risk factors and spontaneous labors
- yes it is safe if not even better than hospital births that low risk women go to
why is homebirth outcomes better
- environment: hospital is too chaotic which can lead to stress
- higher infection rate at hospital
and homebirths have a good outcome because only women with LOW risk are having babies at home
how many stages of labour are there
4
1st stage of labour
- muscles of the uterus start to tighten (contract) and then relax
- these contraction help to efface (thin) and dilate (open) cervix so baby can pass through the birth canal
2nd stage of labour
- cervix is dilated completely (10cm) and the baby is born
3rd stage of labour
- this occurs AFTER baby is born
- mom still has contraction until the placenta is delivered
4th stage of labour
-first few hours after birth (breastfeeding, etc)
what are issues that can arise during the process of birth
-fetal distress (sudden change in fetal heart rate)
- anoxia (oxygen deprivation for babies) can result in death or brain damage
what are the two kinds of reflexes
adaptive and primitve reflexes
what are physical changes in infant and toddler
in the first year, infants grow 25-30 cm and triple their body weight
most weight growth
What is happening physically during infancy and toddler
a lot of brain development
What do we know about 2 year olds and the brain
two year olds have proportionally larger heads as they need to hold their nearly full sized brain
what are the 3 kinds of Brain development that happen in the first 2 years
- synaptogenesis
- neuroplasticity
- myelinization
what is synaptogenesis
this is the creation of synapses. and this is followed by a period of synaptic pruning to make the nervous system more efficient
what is neuroplasticity
the brain’s ability to reorganize neural pathways and connections
what is myelinization
myelin gradually covers individual axons and electrically insulates them from one another- improving conductivity
what are the physical changes between 2-3 years
there are less dramatic physically changes than the first year of life but still impressive
