What is nativism?
NATURE - the human mind is created with pre-existing structures and information (nature)
example: genetics, biology
100
What is a control group?
The group that is similar in every way to the experimental group except for the manipulation of the independent variable
100
Order the tests into structure and function:
MRI, PET scan, postmortem, fMRI, CAT scan, EEG
structure: MRI, CAT scan, postmortem
function: EEG, PET scan
both: fMRI

Explain how action potential moves down a neuron
Dendrites --> Cell body --> Axon --> Axon Terminals
100
The study of how we perceive, think, and solve problems
What is the psychology subfield?
Cognitive Psychology

Freud is known for 2 things...
Unconscious
Psychoanalysis

Compare the independent variable and dependent variables
Independent - the variable that is manipulated
Dependent = the variable that changes in response to manipulation
200
Explain the general functions of all the lobes: Frontal, Parietal, Temporal, and Occipital
Frontal - Intelligence, reasoning, movement, executive control
Parietal - touch, temperature
Temporal - hearing
Occipital - vision
200
What is the difference between GABA and Glutamate
GABA - inhibitory neurotransmitter
Glutamate - excitatory neurotransmitter

The zebra notices a lion lurking in the background. As a result, the zebra's hear rate increases, its pupils dilate, and digestion slows. What is causing this physiological response?
Sympathetic
Fight or Flight!

Who is known for behaviorism?
Watson and Skinner

Katie is taking a math test. She keeps getting the same score over and over again. This would mean that the test is?
(valid, reliable, or both?
Reliable

After a night of drinking, Stephanie is no longer able to walk steadily. What brain structure has been affected?
cerebellum
300
During repolarization, the neuron returns to resting potential. What is going on to cause this?
K+ continues moving out of cell

Kevin suffered a stroke that left him unable to understand what is wife is saying to him. What brain structure was affected?
Wernicke's Area

Locke once said that at birth, the mind is a tabula rasa (a blank slate) that we fill with ‘ideas’ as we experience the world through the five senses. What is this an example of?
Empiricism

If university graduates typically earn more money than high school graduates, this would indicate that level of education and income are
Positively Correlated
400
Your fingers would have more brain volume than your knee. What is an example of?
Proportionality principle
400
Explain the all-or-none-law
If threshold is reached, then AP fires all. If threshold is not reaches, then AP will fire none
400
Explain what is the third-variable problem and give an example
correlation may be produced a third, unmeasured factor
There is a correlation between higher rates of shark attacks and more ice cream sales. The third-variable is that during summer it is more hot so more people are going out to the beach and buying icecream.

Compare structuralism and functionalism
Structuralism (Wundt): conscious experience can be broken down into underlying components, elements, or parts
Functionalism (James): highlighted adaptive purpose, or function of mind and behavior
500
Which of the research designs show cause and effect? Explain why
Experimental research - manipulates variables
Correlational research just looks for associations, and descriptive research only describes what is shown
500
A picture of an apple is shown on the right visual field of a split-brain patient. What is the person able to do?
Draw the apple with their right hand and verbalize that they see an apple

Briefly explain the steps of neural communication, starting with the dendrites and ending with the second neuron
1. Action potential moves down the first neuron, starting with dendrites and reaching axon terminals
2. At the axon terminal, neurotransmitters are released and cross the synaptic gap
3. The neurotransmitters bind to the receptor sites of the next neuron, releasing action potential.

Draw the action potential graph. Label where the potassium (K+) and sodium (Na+) channels open
