Experimentation
the ability of a scientific experiment or trial to be repeated to obtain a consistent result
What is replicability?
disease associated with having too much dopamine
what is schizophrenia?
moving a neurotransmitter from the synapse back into the axon terminal from which it was released
What is reuptake?
Example: The smallest difference of quantity of salt in a soup for us to perceive a difference in taste
What is difference threshold?
Unit of frequency of a sound wave, in vibrations per second
What is hertz (Hz)?
Phenomenon in which a participant experiences a measurable impact/change after a treatment or procedure that has no actual therapeutic value
What is the placebo effect?
drug that mimics or strengthens the effects of a neurotransmitter
what is an agonist?
-70 mV
What is the threshold potential?
just noticeable difference (JND) is proportional to the reference stimulus
What is Weber's law?
Pathway of visual information
What is eyes -> optic nerve -> thalamus -> primary visual cortex (occipital lobe)
For example, ice cream sales and murder rates both increase in the summer.
What is spurious correlation?
What are narcotics?
functions of the myelin sheath
What is insulate the axon and speed up electrical impulses?
the difference in the apparent position of an object as seen by the left and right retinas
What is retinal disparity (binocular cue)?
Color perceived in paired opposites:
red versus green, yellow versus blue,
and white versus black.
What is opponent process theory?
Create an operational definition for "drug addiction"
for example: Using the particular drug more than twice per day.
a region in the left hemisphere that is essential for language production
What is broca's area?
The part of an action potential where Na+ ions rush into the neuron
What is depolarization?
tendency to see an object equally bright even when the intensity of light around it changes
What is brightness constancy?
Our cerebral cortex basically synthesizes a color perception based on patterns of light coming in from various parts of the retina
What is the retinex theory?
the probability that purely chance variation would
achieve a difference as large as the one observed in the sample
What is p-value?
The three major structures of the limbic system and their function
amygdala - fear, emotion, memory
hippocampus - spatial memory
hypothalamus - homeostasis, motivation, aggression
a disease where the immune system attacks the myelin sheath, and it begins to degenerate. It slows the communication to muscles eventually leading to loss of muscle control.
the central area of the retina that has the largest density of receptors
What is the fovea?
Condition in which bones connected to eardrum cannot transmit vibrations to cochlea
What is conduction deafness?
