Your personality is based on your genes.
The personality traits you are born with stay
the same regardless of the environment you
grow up in.
This refers to the individuals innate qualities.
Personality begins to develop during the
“critical period.”

Nature has more effect on someone’s
personality than nurture does.
DNA is a crucial determinant of personality.
Genes are the basic units that pass on
personality from one generation to the next.
It is not determined by one gene.
- Many genes work together to determine it.

Scientists have conducted studies on twins
who were separated at birth.
- Twins who met when they were adults
had many personality traits in common.
- When separately interviewed, the twins’
answers were nearly identical.
- This is a result of their identical DNA.
Separated identical twins share mannerisms.
- Posture

Psychological/personality traits are
influenced by heredity.
- Intelligence, traditionalism, risk avoidance,
aggression, and leadership
Identical twins’ DNA allow their personalities
to be more similar than fraternal twins’.
Scientists have a theory that intelligence is
inherited.


Cognitive ability is said to be inherited
Example:
A child with intelligent parents, but raised
in a less intellectual environment would
do poorly in their early ages, but their IQ
would spike at an older age.
During twin studies, nature/nurture was
tested.
- Identical twins who had grown up in two
different households had identical personalities.
 Someone’s genes gives them a personality, it’s
what they are born with.
- Everyone should be nurtured, but it
doesn’t create a personality.

Personality traits are inherited.
Your genes have more effect on your
personality than your environment does.
Although good parenting is important, it
does not determine who you are.
Nature determines who you are.
