Sensing and Perception
Sense
Imp Definitions
Sensory Receptors
Special cells
convert physical energy to neural impulse
by process of
Transduction
Converting one signal to another signal
Scintific Name
Thresholds
Absolute Threshold
minimum level of Stimuly
after which we detect it :!:
what
smallest amount of stimulus
Which
Detected
For
1 more item...
Example
Audio threshold of a human (ideal condition)
12Khz
Difference Threshold
Smallest difference in stimulus that can be detected
Amount by which
Two stimulus must differ
to be considered as different
Recongition threshold
Miinimum level at which stimuly is not only detected but also recognised
Sensory Deprivation
Reduction or removal of stimulus from sense organs
May be Intentional or Unintentional
Sensory Threshold
Absolute Threshhold
Adaptation angle
Species adopted to?
Those stimulus which maximize survival potential
Examples
Eagle ► Eyesight
Owl ► See in the dark
Motivational Factors
Cost / Rewards affect detection
Refer Signal Detection Theory
Signal Detection Theory
Why important
challenges the concept of Absolute threshold
Theory says
Cost and benefit affects
Stimuli detection
More the cost after detection of stimuli
lesser chances to detect it
Eg. Doctor Sights a dark spot in patient's chest X-RAY
