Untitled Flashcards Set
Unit 1:
Nature vs. Nurture Debate
Nature is things that are genetically predisposed and characteristics that we are born with.
Nurture is external factors that influence us like family and education.
Some people believed nature was predominant influence on our behaviors whereas other believed nurture was.
Middle ground is interactionist perspective.
The Evolutionary Perspective
natural selection affects human behaviors and mental processes
Traits that Ensure survival and reproductive success become dominant traits
Some people have used this to discriminate in the past.
Eugenics
Idea that people can improve the human race by encouraging people with “desirable” traits to have kids.
Positive eugenics -> promotes reproduction by individuals that have traits viewed as more desirable
Negative eugenics -> seeks to prevent reproduction by individuals who have traits deemed as undesirable.
Not used anymore because it is unethical and ignores scientifically complexity.
Twin studies
Compare sets of identical twins (almost 100% genes shared) and sets of fraternal twins (about 50% genes shared) raised together/separately
Family studies
Look at how traits run in families by comparing parents, siblings, and relatives
If trait appears more often in family members, it suggests genetics play a role.
Since families share environments, it can be hard to tell whether genes or surroundings have a bigger influence
Adoption studies
Compare adopted kids kids to biological and adoptive parents
If more similar to biological parents, genetics plays a bigger role. If more similar to adoptive parents, environmental factors
Criticism of Evolutionary Psychology
Many psychologists take issue with elemnts of evolutionary psychology as it starts with an effect and works backwards to propose and explanation
Unethical and immoral individuals have used to discriminate against
Overlooks the effect of cultural expectations
Nervous system

Neural transmission
At rest, a neuron maintains a resiting potential, meaning it has a stable charge
When stimulated, a neuron reaches its threshhold which triggers depolarization
An electrical signal travel down the neuron
Follows the all or nothing principle
Neuron fires completely or not at all
After firing, a neuron has a refractory period
A brief period where it cannot fire again
Once signal reaches end of neuron, neurotransmitters are released into synapse (gap between neurons)
Neurotransmitters are either reabsorbed by reuptake or broken down
Action potential

Detecting anything at all
Diference threshold/Just-noticeable difference
The smallest detectable change in stimulus intensity
Detecting change
Weber’s law
Ability to detect differences depends on proportion of change rather than a fixed amount
As intensity of stimulus increases, a larger change is needed for a person to perceive a difference
Example: small weight change is noticeable if you are holding a light object. If you are holding a heaving object, small weight change is not noticeable.
Sensory Adaptation
