Nature vs. Nurture

Controversy as to which has more effect, genetics or the environment when attempting to explain human behavior


basic structural unit of a living thing


inner area of a cell that contains chromosomes and genes


rod shaped structures that carry genes (thread like strands of DNA)


basic building blocks of heredity, determine our individual biological development


a spiraling, complex molecule containing genes


biochemical sequences that defines genes


Common sequence of nucleotide letters that are within human DNA a profile that makes us human

Gene Complexes

Groups of genes that determine human traits. (behaviors)

Linkage Studies

Look for patterns of inheritance of genetic markers in large families in which a particular condition is common

Genetic Markers

A segment of DNA that varies among individuals and has a known location on a chromosome and can function as a genetic land mark for a gene involved in a physical or mental condition.

Molecular Genetics

Molecular structure and function of genes (identify the specific genes that influence behavior)

Charles Darwin

The idea that traits that help lead to increased survival or reproduction will most likely be passed on to future generation.


error in gene replication

Evolutionary psychology

study of evolution of behavior using the principle of natural selection


emphasizes an evolutionary explanation of social behavior


Socially learned behaviors and expectations that are associated with the two sexes


Physical features signifying that one is either a male or female

Behavior Genetics

Genetic and environmental influences on behavior (study individual differences)


Every non-genetic influence

Identical twins

Develop from a single egg that splits; genetically idetical

Fraternal twins

develps from two seperate eggs

Concordance (Concordance Rates)

The degree o similarity in pairs of twins with respect to the presence of absence of a particular disease or trait.

Seperated Twins

-Share Personality Traits
_Identical twins are much more similar than fraternal twins


Inborn emotional excitability
Jerome Kagan


Intense, fidgety, excitable, nervous; may have symptoms of anxiety in later years


easy-going, quiet, placid; easygoing and extroverted in later years

New York Longitudinal Study

(Chess and Thomas 1996)
EAsy going children: 40%
- playful and respond positively to new stimuli
Difficult Children
-react negatively to new situations or people, irritable disposition, difficult time establishing sleeping and eating schedules.
Slow-to warmup
-inhibited children low activity levels, avoid novel stimuli, require more time to adjust, react to unfamiliar situations by becoming withdrawn.


gene-environmental interaction

Molecular Genetics

Molecular structure and function fo genes


10% influence their children
political affiliatioin

Experience and Brain Development

The more you work your brain the more extensive your brain can be

PEer influence

May exceed parental influences


Food you eat, language, adn accent


Rules for accepted and expected behavior

Personal space

Buffer Zone


self-replicating ideas, fashion, and innovations passed from person to person

X Chromosome

Sex chromosomes found in both females and males
Men have one females have two

Y chromosomes

sex chromosome found in only lales


Male sex hormone


A set of expectations about a social position, defining how those in a position out to behave

Gender Role

a set of expected behaviors for males and females

Gender identity

one's sense of being male of female


the acquisition of a traditional masculine or feminine role

Social Learning Theory

We learn social behavior by observing and imitating and by being rewarded or punsihed

Social-cognitive theory

How we form our conceptions and perceptions based on social context

Gender Schema Theory

We learn from our cultures a concept of what it means to be male or female and we adjust our behavior accordingly
