Vision - receptors in eyes respond to light
-
Hearing - receptors in ears respond to sound and
vibrations
-
Somatosensation - awareness of body
-
Taste - receptors on tongue respond to chemicals
-
Smell (olfaction) - receptors in nose respond to
chemicals
-
Vestibular - inner ear senses gravity and movement
-
6 senses
Sensation - how your senses transform physical properties of the
environment and body into electrical signals relayed to brain
-
Apprehension of the world by means of our senses
○
Link to inner and outer world
○
Determines what we believe is real/exists
○
Perception - process of organising, selecting and interpreting signals
-
All our different senses transform physical input into same
currency - electrical impulses in brain
○
How come some electrical impulses experienced as sight
others as sound etc?
○
How does brain know what is causing the stimulation it
receives and what happens if it is incorrect?
○
e.g. synesthesia - see letters and numbers as colours, senses
get mixed up
○
The problem of qualia
-
All our knowledge of the world and ourselves mediated by
our senses
○
If our senses can make errors, how do we know what's real?
○
e.g. café wall illusion, lines are actually straight
○

It is an active process of organising info into meaningful
and useful representations of the world
-
Perception not just the "registration" of what exists in the
world
○
Fallibility of the senses - errors and illusions
-

Document Summary
Sensation - how your senses transform physical properties of the environment and body into electrical signals relayed to brain. Vision - receptors in eyes respond to light. Hearing - receptors in ears respond to sound and vibrations. Taste - receptors on tongue respond to chemicals. Smell (olfaction) - receptors in nose respond to chemicals. Vestibular - inner ear senses gravity and movement. Perception - process of organising, selecting and interpreting signals. Apprehension of the world by means of our senses. All our different senses transform physical input into same currency - electrical impulses in brain. How does brain know what is causing the stimulation it receives and what happens if it is incorrect? e. g. synesthesia - see letters and numbers as colours, senses get mixed up. Fallibility of the senses - errors and illusions. All our knowledge of the world and ourselves mediated by our senses.
