exosystem
Polygenic inheritance
occurs when a characteristic is influenced by multiple genes
What is the difference between a critical period and a sensitive period?
critical period: limited period of time when exposure to certain environmental events is necessary for development to occur
Sensitive period: a period of time when it’s optimal (but not necessary) for certain environmental event to occur
Chronosystem
environmental events that occur over a person’s lifespan
Active genotype-environment correlation is also called ________
niche-picking
Canalization
the tendency for genetic make-up to restrict developmental outcomes regardless of environmental circumstances
Dynamic systems theory concludes that development depends on multiple factors and that _______ behaviours leads to ___________ behaviours
