TRANSDUCTION
TURNING PHYSIAL STIMULUS INTO ACTION POTENTIAL
sensation
when sensory information is detected by a sensory receptor
Sensory receptors
specialized neurons that respond to specific types of stimuli
ABSOLUTE THRESHOLD
the level of a stimulus at which the stimulus can be detected 50% of the times it is presented
JUST NOTICEABABLE DIFFERENCE
how much difference does there need to be in a stimulus for the difference to be detected (contextually bound!!—fixed ratio of the original stimulus)
SUBLIMINAL
when transduction happens, but no conscious processing—effects are overstated
Weber’s Law
the difference threshold is a constant fraction o the original stimulus
PERCEPTION
how information is organized, interpreted, and consciously experienced
bottom-up processing
- how perceptions are built from sensory input
- sensation!!!
- physical process
top-down processing
- available knowledge, previous experience, thoughts influence how we interpret information
- perception!
- psychological process’
sensory adaptation
-
perception dulls after a long exposure to a stimulus
- sensory systems respond more strongly to changes in stimulation than to constant stimulation
inattentional blindness
we often miss information if our attention is placed elsewhere
