What is the difference between sensation and perception?
Sensation is the stimulation of sense organs by physical stimuli, while perception is the interpretation of that sensory input.
What is the role of Fechner’s law in sensation?
Fechner’s law involves the subjective sensation's relationship with the logarithm of stimulus intensity.
