Chapter 11 Flashcards
what are the three types of major changes overtime
physical development
cognitive development
social/emotional development
why did psychologists think that development stopped at some point in their childhood
because there is a transitional point where the internal influences were becoming overshadowed by the external ones
what is an example of discontinuous development and continuous
continuous = gradual like acorn growing on a tree
discont = butterfly emerging from its larvae
- same things with some kids, they grow overtime or have a sudden growth spurt
what does the universal vs ecological approach on development explain
universal = development as common to all people
ecological = emphasizes the influence of environment and culture on their development
explain the development that occurs when fertilization in the eggs happen
- zygote - goes thru mothers fallopian tubes to the uterus where it forms into an embryo
- longer than this = fetus
what are the three germ layers that differentiates in the zygote
ectoderm, mesoderm, endoderm
- ecto = nerve tissue and skin
- meso = muscle and bone
- endo = soft tissue, organs, digestive tract
week 4 = CNS developed, week 7 = cerebral cortex
T/F errors in the eggs and sperm are more likely in older parents
true
- older ppl = long period of time where their eggs have been exposed to environmental influences = high probability of issues
what is teratogen
it is any agent that can produce harmful effects in the zygote, embryo or fetus
- alcohol
- prescriptions for epilepsy
- prozac, zoloft = antidepressants
- aspirin
- linked to facial abnormalities, ADHD, heart defects, premature birth
- weed
what is fetal alcohol spectrum disorder
FASD
- alcohol consumption by pregnant women
- physical abnormalities, growth, skin folded, small head circumference, cognitive and behavioral problems
T/F HIV can be passed from mother to child
true
pregnancy, birth, breastfeeding
male and female sex chromosomes
male = XY
female = XX
but sometimes their genitalia doesn’t match up with their appearences
what does pruning in the Nervous system development mean
the process in which unused or unnecessary neurons and synapses are eliminated in order to enable more efficient neural processing
t/f myelination increases during childhood
true
myelinated systems are faster and more efficient
how does motor development in childhood proceed?
- head to toe direction = controlling the muscles of the neck and shoulders allows 2-month old infants to raise their head
- at the midline - arms and fingers
- some culture = different timeline to develop these motor milestones
what are some impacts on gender identity in children
parental and societal socialization
biology
what did Jean Piaget say about the development of cognition in children
interested in the errors made by the children than in their correct responses
- developed at distinct stages
- cognition matures as the child increasingly uses concepts and organizing schemas to think
what is assimilation
the incorporation of new learning into an existing schema without the need to revise the schema
what is accommodation - Piaget
the incorporation of new learning into an existing schema that requires revision of the schema
- even tho some birds can fly - there can be expections
what does equilibration mean - Piaget
the process by which a child engages in assimilation and accommodation in order to make sense of the world
what is the sensorimotor stage
first stage of piaget theory
begins at birth - 2 yrs old
- here and now rather than the past and future
- sensations immediately evoke motor responses
what are circular reactions
reptitve behaviours during the sensorimotor stage
primary circulation rxns = infants own body - fingers in mouth and suck and do it again
secondary circulation rxns = other ojects in mouth that are not its own body = toys
what is the object permanence during sensorimotor stage
ability to form mental representations of objects that are no longer present
- growth in the prefrontal cortex
what is the preoperational stage - piaget
yrs 2 -6
use of symbols, egocentrism and limits on the ability to reason logically
- limited by belief that appearances are real (superheros)
what is conservation (preoperational stage) - piaget
the ability to understand that changing the form or appearance of an object does not change its quantity
