Nature vs Nurture
Whether a person’s traits and behaviors are determined more by inherited genetics (nature) or by environmental factors like upbringing and experiences (nurture).
Natural Selection
The principle that the inherited straits enabling an organism to survive & reproduce in a particular environments will most likely be passed on to succeeding generations.
Evolutionary Psychology
The study of the evolution of behavior & the mind, using principles of natural selection
Behavior genetics
The study of the relative power & limits of genetic & environmental influences on behavior
Mutation
A random error in gene replication that leads to a change
Human genome
Our common set of genes
Environment
Every nongentic influence, from prenatural nutrition to our experiences of the people and things around us.
Humans family = biological heritage & common Social behaviors, company of people with similar attitudes & attributes
Heredity
The genetic transfer of characteristics from parents to offspring
Genome
The complete instructions for making an organism
Identical (monozygotic) twins
Individuals who developed from a single fertilized egg that split in 2, creating 2 genetically identical organisms
Fraternal (dizygotic) twins
Individuals who developed from sperate fertilized eggs. They are genetically no closer than ordinary siblings, but they shared a prenatal environment.
Biological vs. Adoptive Relatives
Interact (Gene-enviromental interation)
The interplay that occurs when the effect of one factor (environment) depends on another factors (ex. heredity)
Epigenetics
“above” or “in addition” (epi) genetics; the study of the molecular mechanism by which environments can influence genetic expression (without DNA change)
Personality
An individuals characteristics pattern of thinking, feeling, & acting
Psychodynamic theories
Theories that view personality with a focus on the unconscious mind & the importance of childhood experiences
- From freud
Psychanalysis
Frued’s theory of personality that attributes thoughts & actions to unconsious motives & conflicts; the techniques used in treating psychological disorders by seeking to expose & interpret unconsious tensions
Unconscious

Bottom part of iceberg
Superego
The partly conscious part of personality that represents internalized ideals & provides standards for judgement (the conscious) & for future aspirations
Ego
the partly conscious “executive” part of personality that medicates among the demands of the Id, superego,& reality
Operates on the reality principle,satisfying the id’s desires in ways that will realistically bring pleasure rather than pain
Personality Development
Forms during first few years of life
Oral (0-18 months): Pleasure centers on the mouth.
Anal (18-36 months): Focuses on bowel and bladder control and the demands of toilet training.
Phallic (3-6 years): Genitals become the pleasure zone, and children navigate the Oedipus complex (boys) or Electra complex (girls).
Latency (6-puberty): Sexual feelings are dormant and energy is focused on school and social activities.
Genital (puberty on): Mature sexual interests develop.
Defense mechanisms
The ego’s protective methods of reducing anxiety by unconsciously distorting reality
