What are the 2 main types of developmental research designs
cross-sectional
- dont account for cohort effects
-cheaper
Longitudinal
- expensive
- attrition
more accurate
what are 3 ways nature and nurture intersect
gene enviroment interaction
Nature via nurture
Gene expression
what is a cross-sectional design
a design that cuts into time taking people from a variety of age groups
What is a longitudinal design
a research design that follows participants over time observing the same person at different intervals.
what is a gene-environment interaction
the impact of gene behaviour depends on the environment in which the behaviour effects
what is nature via nurture
children with certian genetic predispositions often seek out and create their own environments
what is gene expression
ativation or deactivation of genes by enviromental experiences through development
what 3 stages follow directly after fertilization
germinal
embryonic
fetal
what is the form of the developing child during the germinal stage
blastocyst - a ball of identical cells
cell has yet to specialize
0-2wks
What is the embryonic stage of development?
2-8wks
blastocyst becomes embryo
limbs, facial features, major organs (heart, lungs, and brain)
begin to develop.
what is the fetal stage of development
9wk - birth
the embryo becomes a fetus
physical maturation / bulking up
what are obstacles to normal fetal development
- exposure to hazardous environmental influences
- biological influences resulting from genetic disorders or errors in cell duplication during cell division
- premature birth
what are 2 newborn reflexes
sucking reflex and rooting reflex
what is the sucking reflex
an automatic response to oral stimuli
if something is put in a baby’s mouth then it will clamp down and begin sucking
what is the rooting reflex
if an infant’s cheek is touched they will turn their head in anticipation of eating
what are the changes in body prepotion during development
body parts grow at ununiform rates compared to each other
what are primairy sex charisterics
features such as the reproductive organs that distinguish the sexes
what are secondary sex charismatics
a sex differentiating charisteric that does not directly relate to reproduction
Brest
voice
what are 2 physical changes as a result of ageing
menarche
spermarche
what are the 3 perspectives that explain how cognitive development theories develop
- Gradual vs Incremental
- domain-general vs domain-specific
- Physical experience vs social interaction vs biological maturation
what is the idea of assimilation in development
the process of absorbing new experiences into a current schema.
making new ideas fit into the current idea of the universe.
what is the idea of accommodation in development
the altering of a schema to make it more compatible with new experiences.
changing beliefs to fit new experiences
what is the sensorimotor stage of development - Piaget
the first stage of development.
From birth to 2y
children only know what they can see
lack object permanence
lack deferred imitation `
what is the Preoperational stage -Piaget
2y -7y
Can construct mental representations of their experiences
have object permanence
are egocentric
can not perform mental operations on mental pictures
