Research & Stats
An ethical requirement that participants must be told enough about a study to choose whether they wish to participate
What is Informed Consent?
If a person suffers a stroke in the occipital lobe, they are most likely to experience difficulties with this sense.
What is Vision?
The endocrine system is slower than the nervous system and transmits information by releasing these into the bloodstream.
What are Hormones?
The minimum stimulation needed to detect a particular stimulus 50% of the time.
What is the Absolute Threshold?
Nicotine is classified as this type of drug because it excites neural activity and speeds up body functions.
What is a Stimulant?
Dr. Arisella conducts a detailed examination of a single patient with a rare brain lesion over several months.
What is a Case Study?
A researcher stimulating this almond-shaped structure in a rat would likely observe aggression or fear.
What is the Amygdala?
A neuron fires completely or not at all; pushing the "flush handle" harder doesn't make the impulse faster. This is known as this type of response.
What is the All-or-None Response?
As light enters the eye, it first passes through this transparent, protective window.
What is the Cornea?
Alcohol is classified as this because it increases GABA activity and slows body functions.
What is a Depressant?
A principal observes that heavy backpacks correlate with lower GPAs and concludes backpacks cause brain drain. This is the major flaw in her conclusion.
What is "Correlation does not prove causation"?
This structure is the "oldest" part of the brain and is responsible for automatic survival functions.
What is the Brainstem?
While neuroplasticity is the brain's ability to reorganize, this term refers to the formation of new neurons.
What is Neurogenesis?
Nerve cells in the brain that respond to specific aspects of a stimulus, such as shape, angle, or movement.
What are Feature Detectors?
Morphine and heroin are opiates that bind to the same receptors as these natural pain relievers.
What are Endorphins?
In a dataset with incomes of $20k, $20k, and $250k, this measure of central tendency is the most misleading
What is the Mean?
Split-brain patients have had this large band of neural fibers severed to stop seizures.
What is the Corpus Callosum?
Neurogenesis is to creation as Neuroplasticity is to this.
What is Reorganization (or Change)?
This theory explains pitch perception by suggesting that the rate of nerve impulses matches the frequency of a tone.
What is Frequency Theory?
This sleep stage is associated with vivid dreaming and "paradoxical sleep" where muscles are relaxed but the brain is active.
What is REM?
Professor Smith tests a new method at 9 AM and an old method at 2 PM. The time of day acts as this type of variable, ruining the validity of the study.
What is a Confounding Variable?
After a viral infection, a patient can play piano but cannot remember the name of the doctor he met ten minutes ago. This indicates damage to this structure.
What is the Hippocampus?
Evolutionary psychologists explain human behavior in terms of natural selection and this.
What is Survival of the Fittest?
In a split-brain patient, if a picture of a spoon is flashed to their RIGHT visual field, they will be able to do this.
What is Say "I see a spoon"?
A researcher wants to identify which specific areas of the brain are active while a participant is using LSD. She uses what kind of brain-imagining machine that tracks the flow of oxygen-rich blood to active neural regions.
What is an fMRI (functional MRI)?
