| Iris | Colored part of the eye |
| Pupil | Dialation/Constriction |
| 2 Causes of Dialation/Constriction | (1) light, (2) inner emotions |
| Lens | Directs the light to the back of the eye; changes shape to accomidate light coming in |
| 2 Parts in Retina and Functions | Rods: see in dim light; black and white Cones: See color |
| Optic Nerve | Connects eye to the brain |
| Blind spot | Spot by the optic nerve where you cannot see |
| Fovea | Concentration of cones where you see sharpest |
| 2 Issues with vision | Myopia and Hyperopia |
| Myopia | Nearsightedness - See closer more clearly |
| Hyperopia | Farsightedness - See further more clearly |
| Wavelength (in vision) | Hue |
| Amplitude (in vision) | Intensity/Brightness |
| Complexity (in vision) | Whether we see a pure color or a mixture of colors |
| Trichromatic theory of vision | There are 3 major colors (Red, Blue, and Green) which overlap |
| Opponent Process Theory | You either see Black or White/Red or Green/ Blue or Yellow |
| Dual Process Theory | The Trichromatic Theory is at the retina and the Opponant Process Theory is at the optic nerve |
| Trichromat | Can see all the colors (Red, Green, Blue) |
| Dichromat | Can only see two of the colors |
| Monochromat | Sees only black and white |
| Frequency (in audition) | Pitch |
| Amplitude (in audition) | Volume |
| 3 Parts of the Ear | Outer, Middle, and Inner Ear |
| Outer Ear Parts | Pinna, Auditory Canal, Ear Drum |
| Middle Ear Parts | Hammer, Anvil, Stirrup |
| Inner Ear Parts | Choclea, Auditory Nerve |
| Place Theory (on Audition) | There are certain places on the membrane near the choclea taht are stimulated by different sounds |
| Frequency Theory (on Audition) | Hairs in the choclea bend at the same frequency as the sound |
| Nerve Deafness | Issues with the auditory nerve (aka Inner Ear Deafness) |
| Conduction Deafness | Something wrong mechanically that stops sound from reaching the choclea |
| Tinnitis | Ringing in the ear; first indication of hearing loss |
| Gustation | Sense of taste |
| How often children's taste buds change | Every 7 days |
| Difference between children and adults taste | Children taste buds change more frequently so they don't like food with strong taste, while adults can get used to strong tastes |
| 3 Skin Sensations | Pressure, Pain, and Temperature |
| Kinesthesis | Sense of body parts related to the whole body |
| Vestibular Sense | Position of your body; Sense of balance |
| How people are affected by Motion Sickness in different stages of life | Infant - unaffected Child - very affected Adults - less affected |
| Extra Sensory Perception (E.S.P.) | "6th Sense"; No scientific proof |
| Illusion | Perception and sensation don't match up |
| Prosaprognosia | Can't recognize people's faces |
| Figure/Ground | We see figures on a background |
| Closure | We close spaces in our mind to make a recognizable object |
| Perceptual Constancy | Our perception stays the same even with sensory changes |
| Shape Constancy | we can recognize an object, even with change of shape (it's rotated) |
| Size Constancy | We can recognize objects with their true size, (like a person in front of a mountain) |
| Ames Room | A room that plays with our perception of location and size |
| Depth Perception | Ability to know how far something is; learned ability |
| Perceptual Set | Our perception is based on experiences |
