What is Transduction?
Changing physical signals (like light or sound) into electrical signals your brain can understand
What is sensory adaptation?
When you get used to a constant stimulus (like smell or loud noise)
What is the cocktail party effect?
Your ability to focus on one voice in a noisy room
What is synesthesia?
When sense are mixed

What what Prosopagnosia?
Trouble recognizing faces
What are wavelengths?
The distance between waves
-affects color or pitch
What is an accommodation?
How eyes changes shape to focus
What are lens?
Focuses light onto the retina in your eye
What is Nearsightedness/farsightedness?
trouble seeing far or near
What is a retina?
The part of the eye that detects light
What is a Thalamus?
Brain relay center for sensory info
What are photoreceptors? (cones and rods)
Cells in your eyes that detect light- cones see color, rods see in dim light
What are Ganglion cells?
Sends visual info from the eye to the brain
What is a blind spot?
Part of the eye with no photoreceptors
What is Trichromatic theory?
We see color using three types of cones (red,green,blue)
What is Dichromatism/ monochromatism?
types of color blindness
What is opponent-process theory?
We see colors in pairs (red-green, blue-yellow)
What is amplitude?
Height of a wave- affects loudness
What is Frequency?
Number of waves-affects pitch
What is loudness/pitch?
How loud of high a sound is
What is sound localization?
knowing where a sound is coming from?
What is place theory?
Different parts of the ear detect different pitches
What is Conduct deafness?
problem in the outer/middle ear
What is nerve deafness?
Problem in the inner ear or auditory nerve
