Possible Measurements
1.Detection experiment:
Absolute threshold: When do subjects start to perceive the stimulus ?
Absolute threshold: When do subjects start to perceive the stimulus ?
®Limits of the perceptual system
2.Discrimination experiment:
Difference threshold (just noticeable difference, JND): how sensitive are subjects for changes in the stimulus
