Weber's Law: This law states that the just noticeable difference (JND) between two stimuli is proportional to the magnitude of the stimuli. In simpler terms, it means that larger or more intense stimuli require larger differences to be perceived as different.
Sensory Adaptation: Sensory adaptation refers to our diminishing sensitivity towards constant or unchanging stimuli over time. It explains why we become less aware of things like background noise or temperature after being exposed to them for an extended period.
Absolute Threshold: The absolute threshold represents the lowest intensity level at which we can detect a stimulus half of the time. It refers to the minimum amount of stimulation needed for us to be aware of its presence.
