Experiment
Manipulated by the researcher during an experiment
Independent variable
The group that receives treatment during an experiment
Experimental group
The group that receives a placebo, also considered baseline, in an experiment
Control group
Shows behaviors associated with the exp. Group when having received a placebo
Placebo effect
Exp. Where neither the participants nor the experimenter are aware of which condition people are assigned to
Double-Blind
Measured variable within an experiment
Dependent variable
Clear, precise, typically quantifiable definition of your variables- allows replication
Operational definition
Error/ a flaw found within a study
Confound
Assigns participants to either control or experimental group at random- minimizes bias, increases chance of equal representation

Random Sample
Accurate results
Validity
Same result every time
Reliability
Adv: real world validity (observe people in their own setting)
Disadv: no cause and effect
Naturalistic observation
Adv: identify relationship between two variables
Disadv: no cause and effect
Correlation
Variables vary in the same direction
Positive correlation
Variables vary in opposing directions
Negative correlation

Case study
Shape of the data
Descriptive stats
Average (in normal distribution)
Mean
Middle number (use in skewed distribution)
Median
Occurs most often in a set of numbers
Mode
Establishes significance (meaningfulness)
Significant results NOT due to chance
Inferential statistics
- confidentiality
- informed consent
- debriefing
- deception must be warranted

Reuptake
Selective serotonin reuptake inhibitors (SSRI) are used to treat what disorder?
Depression
Oldest part of the brain
Hindbrain
Part of the brain that controls movement
Cerebellum
Part of brain that regulates vital organs (heart rate, blood pressure, etc)
Medulla
Part of the brain that controls sleep/arousal
Pons
Part of the brain that allows us to have attention
Reticular Formation
Part of the brain that allows for higher thought processes
Forebrain
Part of the brains, regulates emotions and fear
Amygdala
Part of the brain that is essential for memory 
Hippocampus
The amygdala, hippocampus, and hypothalamus are all parts of the system
Limbic System
The relay center of the brain for stimuli 
Thalamus
The part of the brain that controls the reward and pleasure centers as well as eating behaviors 
Hypothalamus
Damage this part of the brain causes an inability to produce speech 
Broca’s Area
Damage this part of the brain causes an inability to comprehend speech 
Wernicke’s Area
The outer portion of the brain that also has a higher order of thought processes
Cerebral cortex
Part of the brain that is located on the back of the head tied to vision
Occipital lobe
Part of the brain used for decision-making, planning, judgment, movement, and personality 
Frontal lobe
Part of the brain located on the top of the head and in charge of sensations
Parietal lobe
Located on the sides of the head (temples) in charge of hearing and face recognition 
Temporal lobe
This part of the brain has a map of our sensory receptors in the parietal lobe

Lateralization
Who conducted the split brain experiments?
Gazzanaga and Sperry
What happened in the split brain experiments?
Images shown to the right hemisphere will be processed in the left and vice versa. Patient verbally identify what they saw. 
The brains ability to “heal” itself
Brain plasticity
Another term to describe identical twins

Difference threshold
A theory with the means to measure the ability to differentiate between information-bearing patterns and random patterns that distract from the information
Signal detection theory
Diminished sensitivity as a result of constant stimulation
Sensory adaptation
The tendency to see something as part of a group- speeds up signal processing

Cocktail party effect
 What is the correct order that vision occurs in the eye?
(Optic nerve, bipolar cell’s, rods/cones, optic chiasm, occipital lobe, cornea, retina, lens, light, pupil, ganglion cells)
Light, cornea, pupil, lens, retina, rods/cones, bipolar cells, ganglion cells, optic nerve, optic chiasm, occipital lobe
Protects the eye
Cornea
Controls the amount of light that can enter the eye
Pupil/iris
Focuses the light on the retina in the eye
Lens
The area of best vision (cones)
Fovea
Allows us to see black and white and in dim light
Rods
Allows us to see color and in bright light
Cones
These cells connect rods and cones to ganglion cells
Bipolar cells
Opponent processing occurs here within the eye
Ganglion cells
This occurs where the optic nerve leaves the eye
Blindspot
Specialized cells that see motion, shapes, lines, etc.
Featured detectors
Siri that there are three cones for receiving color, blue, red, and green
Trichromatic
Complementary colors are processed in ganglion cells, which explains why we see after images
Opponent process
Visual system overwhelms all others (nauseous in an IMAX theater vision trump’s vestibular)
Visual capture
Recognize the objects do not physically change despite changes in sensory input (size, shape, brightness)
Constancies 
Adjacent lights blink on and off and succession, which makes it look like there is movement
Phi phenomenon
Motion produced by a rapid succession of slightly varying images (animation)
Stroboscopic movement
