Unit 3: Sensation and Perception
Sensation and Perception
Sensation(activated)
Perception (analyzed)
Transduction (sensation to perception)
Sensory adaptation
decreased response to continuous stimulus
Sensory habituation/Perceptual adaptation
perception needs focus
Cocktail-party
phenomenon
increased involuntary response to calls in crowds
Senses
Energy
hearing(vibrations)
Vision(electromagnetic)
touch(pressure)
Chemical
Smell
Taste
Positional(balance)
kinesthetic
Vestibular
Vision
Step 2: Within Eye
Cornea(cover)==>
pupil("camera's shutter")==>
Iris( muscles) ==>
Lens(curved and flexible for light focus)==> Retina
Step 3: Transduction
Retina(light is reversed, it activates neurons)
Cones
around center of retina
1st layer cells
Rods
Outnumber cones
respond to black & white
distributed throughout retina
Step 1: Gathering light
Color = intensity(brightness) + wavelength("real color")
Wave length: UV/X-ray < visible light < infrared/microwaves/radio waves
Red reflect red, black reflect none, white reflect all
Step 4: Within Brain
