Psychologist who used experimental psychology to create a law on just noticeable difference
Who is Ernst Weber
100
This structure receives light focused by the lens, converts it into neural signals, and sends these signals to the brain for visual recognition. It contains photoreceptors known as rods and cones

What is the retina
100
attention gets drawn to a certain place, everything else becomes background noise
What is the cocktail party effect
100
Failing to see something because our attention is elsewhere
What is inattentional blindness
100
Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
What is bottom up processing
200
psychologist who founded psychophysics
studied the mathematical relationship between perception and the physical intensity of a stimulus
absolute thresholds
Who is Gustav Fechner
200
It plays a crucial role in hearing by converting sound vibrations into electrical signals that the brain can interpret.
Damage to the structure can cause hearing loss/Ear-GettyImages-586038190-42999e6443b441d5876c5e3c5dd640cf.jpg)
What is the cochlea
200
Mental filters that organize our info about the world
What are schemas
200
How we perceive objects to differentiate the main thing we are looking at from its background
What is figure ground
200
The activation of certain associations, thus predisposing one's perception, memory, or response
What is priming
300
Swedish neurobiologist and Canadian neurophysiologist who won a Nobel Prize for their studies of visual perception and feature detectors
Who is Torsten Wiesel and David Hubel
300
Tastebuds that detect differences in taste- sweet, sour, salty, bitter
What is papillae
300
optical phenomenon illusion of viewing motion
What is the phi phenomenon
300
The theory that opposing retinal processes enable color vision
Best explains after images
What is the opponent process theory
300
The theory that the spinal cord contains a neurological mechanism that blocks pain signals or allows them to pass on to the brain
What is the gate control theory
400
Psychologists who developed the trichromatic theory which states that there are 3 different retinal cones for 3 different colors
Who are Thomas Young and Hermann von Helmholtz
400
It transmits sensory information for vision in the form of electrical impulses from the eye to the brain. Damage to this structure can cause loss of vision.
The structure at the end of the eye
What is the optic nerve
400
How we group objects together, how close they are together
What are Gestalt principles
400
The delay in reaction time between congruent and incongruent stimuli
When the color purple is written in red for example
What is the Stroop effect
400
The minimum stimulation needed to detect a particular stimulus 50% of the time and trigger a reaction or produce a sensation
What is the absolute threshold
500
Studied attention
change blindness and inattentional blindness
Who is Daniel Simmons
500
three loop-shaped, fluid-filled tubes in the inner ear that play a crucial role in maintaining balance and stability. (vestibular sense)
detect rotations and angular movements of the head, helping you to keep your balance as you move.
What are the semicircular canals
500
We know objects stay the same even though they look like they are changing
What is perceptual constancy
500
Perceptions begin with the most general and move toward the more specific, information processing guided by higher level mental processes
What is top down processing
500
A laboratory device for testing depth perception in infants and young animals
What is a visual cliff
