study guide from teacher Flashcards
- What are the stages of prenatal development?
• Initial stage
◦ Zygote… Last only 1-2 wks
◦ If chromosomes absent or in excesss … Results in abnormal development n growth of zygote
◦ Sometimes abnormalities inherited …. Occur without reason
◦ Thus, half of zygotes dont survive.
• 2nd stage
◦ Embryo stage : bc it is now implanted in the uterus … Zygote enter embryo stage
◦ 2-8 weeks
◦ Here the heart begins to beat By 2 months
◦ Gender differentiating occurs .. Males with XY … Male sex organs begin :)
◦ Male embryos less likely to survive .. 126 male embryos to 100 female embryos .. 105 males born but 100 females
◦ Sometimes errors occurs in genetic replication… Male XY born with female external genitalia
▸ Intersex or hermaphrodite.. Now called disorder of sex development
• 3rd stage
◦ 9 wks- birth
◦ Now known as fetus
◦ Teratogens
▸ Basically toxic shit for babies
▸ Dangerous for fetal development
▸ Ex:cigarettes, alcohol, x-rays, infection outs diseases
▸ HIV: by birthing, breast feeding, labor
◦ Experiences in the womb contribute to the developing person :)
▸ Fetus learns the sound of the mother n prefers it
▸ If momma is stressed and have anxiety babies prone to behavior problems
▸ Study : exposure to hormones in the womb was found to correlate with development of cognitive abilities.. Ring fingers that were longer than index finger a sign of high prenatal testosterone exposure, correlated with higher scores on standardize math test .. Girls with a short ring fingur had a high literacy SAT score … If you have a longer ring figure … Ur brain may be more developed !!!
◦ By 6 months baby can survive being born !!!
▸ Calld age of viability
◦ Full term baby:::: 37 weeks
◦ Babies more likely to die if mother dies… Back in the days mothers died in 1:100… Now 1:10,000 :)
- Describe some of the problems that can result from environmental influences during the prenatal period of development.
In 3rd Stage : 9 weeks - birth
now its a fetus,
Teratogens: toxic agents from the environment, such as disease, poison, or. Drugs that can harm the fetus.
Ex: cigarettes, alcohols, x-rays, infectionsous diseases
Fetal alcohol syndrome: irreversible brain abnormalities caused by the mother’s consumption of alcohol during pregnancy
- Describe physical development in infants and newborns.
• Physical growth faster in the young
• Infancy cranial capacities
◦ Infants 25%
◦ Age 2.5 75%
◦ Age 5 90%
• However, when the brain is being stimulated the more developed and heavier the brain is
◦ Their synapses also changes … They were 50% larger
◦ Stimulating environment = larger more interconnected brains
• Young children have greater plasticity
◦ This means basically that the brain is able to adapt and I think perhaps change the way it interconnects to compensate to the loss that happen !!!
• Learning to walk
◦ 2 day old baby: curled in a fetal position
◦ 3 months : learn to roll over
◦ 6 months: sit up by themselves
◦ 9 months: crawling
◦ 12 months: stand alone/walk alone :)
• Usually the same for every kid!
• Stage theory
◦ Predicts thet babies must crawl b4 they walk.◦ It is like a requirement bc of neuromuscular stages
▸ But this is based upon cultural settings..some cultures carry babies until 1 yr and babies skip crawling and just scoop themselves when. Seated not crawling
- Discuss the dichotomy of nature vs. nurture and why it is important for theories of development.
• John B Watson
◦ Claimed nurture could change the future of any child to become anything evens thief or a beggar lol
• this guy believed that learning from the environment was the primary determinant in development
◦ Environmental factors ( caregivers, peers, rich environments) are important to influence in development !
• Nature weighs in development early
◦ Temperaments of newborns hereditary !!! Omg !!
◦ This temperaments relates to that when they grow as teens (their temperament as a teen)
◦ Genes :(
• Nature and nurture can interact to create patterns of development
◦ …like individual differences in intellectual ability
• Socioeconomic statues …. Low income families … Well the kids tend to do poorly in test bc of their neighborhood schools
• A genre by Environment interaction occurs ;;; genes do matter for intelligence, but only for those children who’d basic needs are already being supported by their environments … High SES house holds
• The role genes depends on reciprocal integration btwn the child and his/Environment
◦ Basically saying that the right environment is needed for biological process to be unfolded
• Basically saying that our choice makes a difference if whe choose to be mean to kids or not… Or become social or not etc etc.
- What are assimilation and accommodation? Give an example of each.
Assimilation: using current concepts in memory to understand new information
Zerba: its a horse!
Here, you just fit it right into w.e u know b4 u saw this new species /
Accommodation: changing concepts in memory to fit new information.
fish and dolphin
It’s a Fish. dad says no its a water animal.
New category: water animal … you create a new overal concept to fit it…
- How does Piaget characterize the way that infants understand their world? (Hint: define sensorymotor development and object permanence)
Sensorimotor stage
• All about learning to grasp and manipulating object and moving through the world
• Focus on
◦ Development of sensory and motor processes
• During this stage there is change … It is called object permanence
◦ 8 months or younger toys … “out of site out of mind”
◦ By 9 months they start looking for these out of site toys …. Implying that they are now thinking about it
• With peek-a-boo they start to learn that gone things are still there… Object permanence… This helps them move to the next stage
Object permanence: babies remembering objects they can no longer see in front of them.
- How do preoperational and concrete operational thought differ, according to Piaget?
In preoperational, He IDed conservation, where kids dont understand that even when u spread out pennies, they are the same amount of pennies when stacked up together or spread closely together… Here, in preoperational stage he also IDed egocentrism, where kids only think their way is the best way … oblivious to other’s perspective, feelings, ideas.
-uses words and images but not logic … preschoolers, kindergartners (2-7)
—-Mo from Moster’s INC>.. called the moster Kitty!
Concere operational:: they are no longer fooled with the pennies, However, they have a hard time to combine 2 dimensions…
– grade schoolers (7-11) thinks logically about concrete objects (or actual objects) .. achieve conservation
- Give an example of how more recent research suggests that Piaget may have underestimated children’s abilities.
• Child chess experts remember more locations of pieces
than novice adults
• But children remember fewer digits
(Micki Chi, U. Pittsburgh)
Babies show evidence of ‘reasoning’ about things they can’t see
BY; Renée Baillargeon U. Illinois also Su-hua Wang, UCSC
Baillargeon’s findings with 3.5 month olds
Possible event (carrot short and does dissapeare from |-|) & Impossible event (long carrot and shouldn’t but does dissapeare from |-|)
First, habituated to both events (actual square [] (not rectangle but square -.-) the carrots went throught.. and did)
TEST: Looked significantly longern at impossible test events ( when the carrots went thorugh a |-| shaped thing and the LONG carrot went right through it dissapearing in the middle.)
- Describe a conservation task and how it would be answered by a preoperational child and by a concrete operational child.
cup of water… in a short glass… then poured into a long glass.
Does the long glass water have more than in the short glass?
Preoperational: yes.
Concrete operational: no… same amount just that the glass is long -.-
- How does the information processing approach contrast with Piaget’s approach?
Information Processing theorist think kids are just novice. like the fish gowing up .. they are quialitative-ly growing… quantinty bc they are the same but just imersing with new data
Piaget’s approach is more of a qualitative approach… where it’s froma catapellar to a buttlerfly… things eolve…
- What is the sociocultural approach to developmental psychology? (Hint: Vygotsky) Give an example of how this approach questions some of the assumptions of previous theories.
- Vygotsky – children’s thinking develops in social contexts, mediated by other people, language, and tools
* “zone of proximal development” – range between what child can do on their own vs with help of others
uhm idk they assume we have a static environment.. which we don’t we all have differential environments which help us learn differently!
we don’t all grow up in a western world….
- What is a critical period? Give an example from animal research and explain why it is controversial to argue that there are critical periods in human development.
Critical period: a period during development where specific abilities must occur.
◦ Ex: ducks 13-16 hrs shortly they start imprinting to follow the momma!!! :D
◦ Highly unethical to do a study so only find kids in the adoption places
• Case study: Genie !!
- Discuss some of the cognitive changes that occur with aging.
- Old ppl show a decline in fluid intelligence (reasoning about new information)
- Crystallized intelligence (or reasoning using knowledge already existing in memory) show no decline with advancing age
- Old ppl do. Know better!!!
- How do the children in the video on “First Errands” illustrate aspects of developmental psychology and cultural variation?
kids with the guidance of parents… they learn…
cultural variation … that each of them had difference in their perspective than we did… we western world would not let a kid of 5-6 yrs go get dipers or yeah..
- What is attachment and why is it important for early development?
Attachment: a deep, emotional bong that an infant develops with its caregiver.
just because kids with secure attachment tend to be better…. idk
- How do Harlow’s studies on monkeys help us to understand human relationships? What ideas about attachment did Harlow’s findings address?
well they were unethincal … isolated bby monkey from mom…. surrogate moms.. 1 wire one cloth..
wire mom had the milk… didnt matter they prefered the cloth mom… contanct !!!
◦ Called it the contact comfort.
▸ The infant monkeys would go get their food/ milk from the wired one but went back immediately to the softer “mom”
◦ When they were startled they would go hug their soft “mom”
◦ And went they took away the soft mom they looked pitiful crying in fear, crouching, and sucking their thumbs. :”(
• Basically found that attachment bonding is a physical (contact) rather than biological (food).
- What is the strange situation?
By Mary Ainsworth
- Home observations in Uganda & Baltimore
- Focused on separation/ reunion of mother/ child
- Developed lab situation to observe attachment behavior
- Parent + Infant
- Stranger appears
- I + S
- I + P
- I
- I + S—
- I + P— Second separation & reunion
4 outcomes…
secure B babies - cried when mom left, but greeted her happily when they came back – didnt play with stranger (65%)
Insecure-Avoidant A babies - babies didnt cry, and aoided contact with mom… played with stranger (20-25%)
Insecure- Resistant C babies –got really upset when left, couldnt be content when mom got back :/ had angry behavior/ proximity ones too (10-15%)
Disoriented/ Disorganized: D babies– got frozen, got confused (5%)
- Describe the different types of attachment described by Mary Ainsworth based on the strange situation. Which type of attachment is “healthiest” according to Ainsworth, and why?
healthiest is SECURe.
secure B babies - cried when mom left, but greeted her happily when they came back – didnt play with stranger (65%)
Insecure-Avoidant A babies - babies didnt cry, and aoided contact with mom… played with stranger (20-25%)
Insecure- Resistant C babies –got really upset when left, couldnt be content when mom got back :/ had angry behavior/ proximity ones too (10-15%)
Disoriented/ Disorganized: D babies– got frozen, got confused (5%)
• Correlated with later school competence
Problem-solving, social competence, cooperation, empathy, self-esteem
- What are some reasons for questioning the idea that healthy attachments are the same all around the world? Describe some of the research findings on attachment in different countries.
Researchers too often…
• see own culture as “normal” and others as “deficient”
• see other cultures as homogeneous
• expect they can take concepts in their own
culture and readily apply them to another culture
Leads to false inferences
In Israel, 50 % avoidant.. they were more independent…
In japan 80% were secure… bc mom’s were given a break from work for about 2 years … they value child n mother connectivity
- Describe Erikson’s ideas about what forms the different stages of development.
Erikson’s Psychosocial Stages
Age ! !Developmental Task
0-1 Trust /mistrust
1-3 Autonomy/shame
3-6 Initiative/guilt ! ! !
6-12 Industry / inferiority
Adol. Identity / role confusion
Early adul. Intimacy /isolation
Mid. age Generativity / stagnation
Old age Ego integrity / despair
- Define ‘resilience and give an example.
Resilience: when u have a shitty as life but some now u come out okay
◦ Partly hereditary !!!
◦ Resilience so ordinary !
◦ Schools can foster resilience by being tightly communicative with students, parents, teachers..
- What evidence is there that observed gender differences could be related to socialization patterns?
- Parents’ conversations with boys and girls
- Autobiographical memory studies (Fivush)
- More overall talk about emotions with girls, especially sadness
- More talk about anger with boys
- Science talk in museums (Crowley & Callanan) (her study in museums n stuff)
- Discuss the differences among authoritarian, authoritative, permissive (or indulgent) and neglectful parenting styles. Which one is associated with more positive outcomes in children? Is this a universal finding?
Authoritative - high nurture, high control
authoritarian - low nurture, high control
permissive- high nurture, low control
neglecting- low nurture, low control
authoritative is more positive,
NO, in mexican cultures u have respeto … in chiniese u have guan !
- What is the important task of adolescence according to Erikson? How are peers important for this development?
• Social development for adolescence
◦ Peer relationships
▸ Have bffs that are makes and can distinguish from peer friendship from that of a romantic relationship
▸ These provide a reference to compare and evaluate a developing identity
▸ Study : grades 7-11 grade … Showed influence of closets friends on the likelyhood of binge drinking or engaging in sexual activity
▸ Peer pressure : marked by conformity of behavior … Peaks during the 9th grade
◦ Peers can influence both negatively or positively
- Give an example of how some aspect of cognitive development would also impact development of social relationships? (thought question!)
object permenance: kniwing something is there or not… you gotta develop security/ trust … trusting someone you gotta know they are there even when they are not
perspective tatking ;;; social competene… not being egocentric anymore (PT) and being able to interact with other with their differ perspective …
