DEVELOPMENT Flashcards
(47 cards)
what is qualitative progress in development?
-Abrupt changes in stages, moving from one stage to the next
what is quantitative progress in development?
-Gradual, continual change throughout development.
What are the key questions in developmental psychology?
Qualitative or Quantitative?
Nature or Nurture?
What are some early genetic disruptions?
- Intellectual disabilities
- Delays in motor development
- Increased risk for a range of health problems
- affects 1-691 babies
What is tetragen?
Environmental agents that can interfere with healthy fetal development (Lead, mercury, carbon monoxide, pesticides.)
What are some factors that can cause early disruptions in the prenatal environment?
Alcohol –> Fetal alcohol syndrome
Smoke –> ADHD
Influenza virus –> Severe mental illness.
What are some prenatal - postnatal continuity notes to make?
- Drinking during pregnancy increases the chances offspring will enjoy alcohol
- Foods consumed prenatally are preferred postnatally
- Newborns show a preference for mothers voice, not fathers.
What are the early capabilities of a newborn child?
- Reflexes: Automatic movements triggered by specific types of sensory stimulation.
- Limited control over their eye, head, and facial movements.
- Will turn their heads in the direction of human voices and gaze longer at drawings of the face like images (8-12 inches away)
What do we know about Imitation in newborns?
- newborns Imitate faces
- Infants seem to seek out others and do as they do
What is the novelty?
Newborns show interest in new stimuli
What is Habituation?
- A form of learning
- Infants become less responsive that have undergone habituation, typically because of a new stimulus.
What is Dishabituation?
The recovery of a response that has undergone habituation, typically because of a new stimulus.
What is motor development? and what do we know about it?
- The ability to coordinate and perform bodily movements.
- Motor skills emerge in sequence from the head to the feet
- Motor skills emerge from the center of the body outward.
- Huge variation in pace development.
What are the different types of crawling?
- Creeping on the belly
- “Army style”
- Scooting on the bottom propelled by one leg.
What do we know about Cognitive development?
-Changes in all of the mental activities associated with thinking, knowing, remembering, and communicating.
What are Piaget’s stages of development?
Sensorimotor stage (Birth - 2yrs)
- Knowledge through senses and actions.
- No symbols or language
- No object permanence
Preoperational Stage (2 to 7)
- Symbols, simple object classification (color, shape)
- Struggle to see situations from multiple perspectives or imagine how situations can change.
Concrete Operational change (7-12)
- Can use multiple perspectives and imagination to solve complex problems.
- Can apply this thinking to concrete objects or events.
Formal Operational Stage (12 years and up)
-Adolescents can reason about abstract problems and hypothetical propositions.
What is object permanence?
- The awareness that objects continue to exist even when out of sight.
- Understanding of natural laws develops gradually over the first two years.
What are some critiques of Jean Piaget’s stages of development?
- Underestimates children’s abilities
- Oversimplifies the process of cognitive development
- Cognitive development is more continuous and less stage-like.
What is the biology behind development?
- Neural proliferation: The creation of new synaptic connections.
- Synaptic pouring: The trimming back of unnecessary synapses according to a “use it or lose it”
- Myelin of axons: The process of insulating axons in Myelin, which speeds their conduct and allows information to move more rapidly through the brain and body.
- Development doesn’t happen evenly
- Sensory areas of the brain mature fastest
- Frontal loves mature more slowly
What is our early social and emotional understanding?
- Infants seek out human faces and respond to the faces they see.
- Infants between four and seven months of age can tell difference between happy, sad, and angry facial and vocal expressions.
What is social referencing?
Using other facial expressions for information about how to react to a situation.
What do we know about attachment?
- First social relationship is with the primary caregiver.
- Refers to the strong, enduring, emotional bond between an infant and a caregiver.
- Imprinting: Attaching to the first moving object an organism sees.
What did Harry Harlow say about attachment?
- Researchers originally thought human infants teach to those who provide food.
- Study of infant monkeys and cloth vs. Wire mothers.
What did John Bowlby say about attachment?
-Comfort, not nutrition, is crucial for human attachment.
Caregiver: Secure base.
