Senses and Perception
Term | Definition |
---|---|
Cornea | Protects the eye and bends to provide focus |
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 |
