ANSWERS
longitudinal study - ✔✔ a study that observes the same participants over a long amount of time.
it minimizes group differences and is expensive.
cross-sectional study - ✔✔ observing various groups over a short period of time. it is cheap but
has large group differences.
cohort effect - ✔✔ the influence of shared characteristics of a group that was born and reared in
the same general period
cross-sequential design - ✔✔ research design in which participants are first studied by means of
a cross-sectional design but also followed and assessed for a period of no more than six years
naturalistic observation - ✔✔ no inference, just observing
participant observation - ✔✔ a confederate interacts with participants without them knowing
correlational analysis - ✔✔ correlation does not equal causation, not controlling other factors bc
it's natural
genotype - ✔✔ genetic makeup of an organism
, phenotype - ✔✔ physical characteristics of an organism

XYY syndrome - ✔✔ masculinized male, learning disablities
fragile x syndrome - ✔✔ more males than females, increased rate of ADHD
turner syndrome (X) - ✔✔ incomplete/delayed puberty
epigenetics - ✔✔ the study of environmental influences on gene expression that occur without a
DNA change (gene and environment interactions)
passive epigenetics - ✔✔ genes for extroverted kid means parents are extroverted
evocative epigenetics - ✔✔ child plays active role in environment where being an extrovert is
positively reinforced
active (niche-picking) epigenetics - ✔✔ find where we fit in
