Sensation and Perception Flashcards
What is the receptor/transductor for the sensory organ of eyes?
Rods and cones (retina) located inside the brains occipital lobe
What is the receptor/transductor for the sensory organ of ears?
Hairs cells in the basilar membrane located inside the cochlea.
What is the receptor/transductor for the sensory organ of nose?
Olfactory cilia located in the olfactory bulb
What is the receptor/transductor for the sensory organ of mouth?
Cell (neurons) in the taste buds
Our body’s ability to takin in physical energy from the outside world…
Sensation
The brains interpretation that information…
perception
Language of the brain…
neural impulse
Translation form physical stimuli to neural impulses (transduce)…
Transduction
Relationship between physical energy (sensation) and the brains interpretation of it (perception)…
Psycho physics
Experimental psychologist…
Gustav Fetcher
When stimulus is constant,you stop paying attention to it…
sensory adaptation
Brain focuses your attention on 1-2 things at a time…
selective atention
Brain is taking in multiple its of information simultaneously…
Parallel processing/ multilevels of processing
When you are at a party and someone else says your name, automatically your attention zeros in on their voice…
cocktail party effect
Detectable input from environment…
stimuli
Aren’t able to see something because you are focused on something else…
inattentional blindness
Height…
amplitude
Distance between peaks…
wavelength
Color…
hue –> wavelength
Brightness/white
amplitude
Lens changes shape automatically, it is also known as “pancakes in the distance”…
accomodation
The ability to see objects near but not far away…
Nearsighted
The ability to see objects far away but not close…
farsighted
Clear spot in the retina, where cones are most commonly located…
forvea
Help with night time vision takes 20-30 minutes to adjust…
rods
Color, clear, adapts quicker in darkness takes 20 minutes to adjust…
cones
What is located in front of the cones?
The ganglion and bipolar cells
What our eyes can’t see which goes directly through the optic disk which does not allow it to go through the rods and cones therefore the brain can’t interpret an image is called…
blind spot
The minimum amount of stimulus that you need to detect it…
absolute threshold
what you can see, hear, taste =
50%
The study of how psychical stimuli are translated in to psychological experience; sensation and perception
