Question:
KME's EPPP Developmental Psychology
GxE Interaction
Answer:
a term referring to the nature versus nurture
debate, indicating that most experts agree that there is an interaction between genes &
environment
Question:
Genotype
Answer:
characteristics that are determined by genetic code
Question:
Phenotype
Answer:
develops from an interaction between genes and
environment
Question:
measurable, observable characteristics (physical & psychological)
Reaction Range
Answer:
our genes set limits on the type of phenotypes
that can occur
Question:
the reaction range is larger for those with "high genetic endowment"
Critical Period
Answer:
limited time span during which biologically
,prepared to acquire a specific bx, env't must be right
Question:
Lorenz & imprinting
Sensitive Period
Answer:
used more often than "critical period" w/

(learning to walk; puberty)
Canalization
Answer:
term used to describe the narrow developmental
path of some characteristics (characteristics that are not influenced by env't)
Question:

Question:
provide evidence for importance of env't
(increase in height, earlier menarche)

, Answer:
a statistic used to estimate the degree to which
a characteristic can be attributed to genetics
Question:
i.e., intelligence average is .50, meaning 50% of individual differences in IQ scores can be
explained by genetics

all or part of the 2nd X chromosome is missing (female)
