2 - prenatal development Flashcards
teratogens
- virus or chemical that can reach embryo and cause harm
- can be deliberate or accidental
- e.g. alcohol
- not all drugs have equally negative consequences, nor are the best indicator
fetal alcohol spectrum disorders (FASD)
- drinking while pregnant
- often causes issues with learning, executive jydgement
- also physical deformities
newborn abililities
- arrive with automatic reflex responses that surrport survival (instincts?)
- arrive with a number of important capacities developed or on the way
- possess a biologically rooted temperament
newborns’ preference for faces
prefer things that are face-like
infancy and childhood: physical brain development
- birth: neuronal growth spurt
- 3-6 months: Rapid frontal lobe growth
- 1 year: most neurons you’ll have, and a messily wired brain
- Development: synaptic strengthening (relavant ones) and pruning (removing connections)
- Early childhood: “Critical” period for some skills (e.g. vision, language)
- Throughout life: Learning changes brain tissue
brains as baby abilities
§ Brain maturation and infant memory
§ Infants are capable of learning and remembering (mobile experiment, Rovee-Collier)
§ Infantile amnesia in one domain (explicit) and not other (implicit)
- babies are learning from day one!!
Social Development of babies
- Infant attachment (babies are chill to everyone for first 6-8 months of life)
- Stranger anxiety (happens 8 months in)
- Attachment based on:
- Gratification of biological needs? (Freud)
- Comfort/familiarity/responsivity? (Harlow)
harlow’s monkeys
is it what’s nourishing you that you determine as mother or comfort?
- two “mothers”, one that’s soft, one that has wire but also gives food
- the monkey will go to the wire one for food, but then return to the soft monkey
showed that Feelings of comfort and security are the critical components to maternal-infant bonding, which leads to healthy psychosocial development.
familiarity as a key to attachment
- Imprinting (e.g. birds; Lorenz, 1937)
§ “Critical” period (usually a sensitive period)
both are basically that it’s best to from bonds in first six months
studying attachment in social development
strange situation experiments
§ Attachment styles: reflect both child’s individual temperament and parents’ responsiveness
§ Early attachment impacts later relationships
attachment styles persist
Secure attachment
- Ainsworth
- majority, healthy
- the toddler prefers his parent over a stranger.
- The attachment figure is used as a secure base to explore the environment and is sought out in times of stress.
- distressed when their caregivers left the room in the Strange Situation experiment
- when their caregivers returned, the securely attached children were happy to see them.
- Securely attached children have caregivers who are sensitive and responsive to their needs.
insecure attachment
- anxious
- avoidant
- less healthy
anxious insecure attachment
super upset when mother leaves and not easily consoled by parent when they come back
avoidant insecure attachment
not upset when parent leaves nor when they come back
§ The toddler reacts to the parent the same way she reacts to a stranger.
□ the child is unresponsive to the parent
□ does not use the parent as a secure base
□ does not care if the parent leaves.
§ When the parent does return, the child is slow to show a positive reaction.
§ theorized that these children were most likely to have a caregiver who was insensitive and inattentive to their needs
issues with attachment styles?
always like to criticize the mother
change is normal, and there’s only modest predictive validity
§ child’s temperament may have a strong influence on attachment
§ attachment varies from culture to culture
Temperament
Difficult
§ Easy
§ Slow-to-warm-up
- Temperament refers to innate traits that influence how one thinks, behaves, and reacts with the environment.
difficult temperment
○ difficult temperaments demonstrate negative emotions and have difficulty adapting to change and regulating their emotions.
easy temperment
○ easy temperaments demonstrate positive emotions, adapt well to change, and are capable of regulating their emotions.
slow-to-warm-up
lower then usual activity levels, NEOPHOBIC (fear of new things), but okay with them after repeated exposure
impact of parenting programs?
Can improve
attachment security
deprivation of attachment
Important note: we are resilient, we bounce back quickly
§ Higher risk for attachment problems, substance abuse, other poor outcomes (BUT see above)
romanian orphanages
horrific deprivation of attachment
really bad proportions – one caregiver per dozen children
Self-Concept in baby
Emerges gradually
* 6 months: self-recognition
* 15-18 months: face schema
* School age: grouping by gender/traits/peers/etc.
* 8-10 years old: stable
Parenting styles (Baumrind)
Authoritarian
§ Permissive
§ Authoritative
§ Early descriptions definitely sound WEIRD-centric
