Developmental Psych Flashcards
In Utero
Language development is happening but not to the extent that we think about language
For example: they have a preference for their mother’s voice
Placenta
Screens/filters harmful substances coming in from mother
Why does the placenta have a problem?
Placenta can’t do it all; things slip through and can harm the baby
These are called TERATOGENS
For example: constant use of alcohol/drugs
Fetal Alcohol Syndrome
- learning difficulty
- low IQ/intellectually disabled
- facial dysmorphology
Examples of facial dysmorphology?
Bridge of nose super wide and thick; lips disformed, teeth with massive gaps, etc.
~ Not just in Fetal Alcohol Syndrome but other genetic conditions as well
Utero Reflexes
can come back as adults; they are innate/automatic survival mechanisms
4 survival reflexes in babies
1.) Rooting reflex
2.) Sucking reflex
3.) Startle reflex
4.) Grasp reflex
Rooting reflex
If you touch the corner of a newborn’s mouth, they will automatically turn their head and root for food/nipple so they can survive
Sucking reflex (coupled with rooting)
If you put a nipple in their mouth, they innately know how to suck out the milk
Startle reflex
If you startle a newborn, they put their hands up in the air for attention
- Attention grabber and then coupled with crying to protect themselves and get help
Grasp reflex
Automatically latches your finger/something if you put near their hand
- Physical/grasping mechanism to prepare themselves and learn motor skills when they get older
What happens to baby reflexes when you age?
They get buried when you no longer need them, but they do disappear entirely
- For some people in adulthood, like those with dementia, these reflexes can reappear (leading you to be dependent on someone else again)
It is a last ditch survival mechanism
What do you remember about the frontal lobe?
Takes up 40% of cortex
Terms of development:
- last part of the brain to develop in utero; doesn’t stop maturing until 25
- AGE 3-6 MOST RAPID DEVELOPMENT OF FRONTAL LOBE OCCURS (explosion of development)
What is happening in the frontal lobe during ages 3-6?
*Language development rapidly increases
*Brain is especially plastic at this time, which is why 3-6!
*Motor skills developing (walking)
** Pruning
Why is it hard to learn a new language when you are older?
Ages 3-6 is the best time to teach a child a new language since the brain is so plastic at this time; the brain is solidified and done growing as an adult, making it much more difficult to learn a new language
What is pruning again?
Links and connection in brain that are not used, so the brain trims away the ones you don’t need in a process called PRUNING
- removing synaptic connections that are unused
What is special about motor development?
It is UNIVERSAL in children and does not vary by region, culture, etc.
Different pace but same order sequence
Universal motor development
1.) Sit
2.) Crawl
3.) Walk
4.) Run
Who was a major player in cognition?
John Piaget
Criticism surrounding John Piaget’s work
The participants of his research were his own kids, so his theories are biased to his children and not on diverse population
- HOWEVER, his stage model tends to hold up though
Piaget’s Schema
1.) Assimilation
2.) Accommodation
- based on knowledge, experience, and exposure
What is a Schema?
Way for us to organize concepts
Assimilation
Integration of new information into existing schema
Accommodation
Introduction of something new and slightly different that changes/broadens a person’s schema
Piaget’s 4 stages of how children learn through adolescence (cognitive)
1.) “Sensorimotor”
2.) “Preoperational”
3.) “Concrete Operational”
4.) “Formal Operational”.
“Sensorimotor” stage
- Age 0-2 roughly
- Learn through interacting with the world (putting everything in their mouth to see what it is; walking and getting into everything, etc.)
- Object permanence
What is object permanence?
Understanding that something exists even if out of sight or hearing (develops during stage 1)
“Preoperational” stage
Higher order functioning (cognitive, etc.)
- Don’t have the necessary ability to perform higher order functioning or mental operations
- Age 2-7
- Language is starting to develop more rapidly
- Conservation (same amount in different vessels…)
- Significant egocentrism rapid in this stage
Conservation
Idea that amounts of things can be the same despite different vessels/sizes
Kids do NOT have this
- Kids think other kids are getting more than them
