Perceptions
Usefulness:
- much of our knowledge comes from perception ( 5 senses)
Limitations:
- we are sensitive only to certain ranges of stimuli
- our senses sometimes deceive us - optical illusion
- our expectations influence what we perceive
We often trust our eyes, we trust what we see.
but yes, perceptions has its own limitations
eg,
you saw a old man lying unconsciously on the road, and a truck is in front of him.
perception : the truck banged the old man
but, your perception may be wrong.
the old man could have a heart attack even before the truck banged him.
lesson learned:
perception has its own limitation
what you see may not be exactly what had happened.
