Transforming physical energy into the form of neural messages.
Stimulation of a sensory receptor that produces a neural impulses.
A process that makes sensory patterns meaningful.
Amount of stimulation for a stimulus to be detected.
Smallest mount by which a stimulus can be changed and the difference is noticeable.
Steven's Power Law
As magnitude of stimulation increases the perception of magnitude gets smaller.
The size of JND in proportional to the intensity of the stimulus.
Loss of responsiveness after stimulation have remained unchanged.
sensory detections are affected by the characteristics of the stimulus the background stimulus and the detectors state of mind.
Cocktail Party Effect
What happens when we struggle to identify a single-detection amongst many.
