Final answer:
Subliminal perception occurs when a stimulus is presented below the absolute threshold and is detected by an individual without conscious awareness. It has little effect on behavior outside of laboratory settings.
Step-by-step explanation:
When the stimulus presented is below the level of the consumer's conscious awareness, the result that occurs is called subliminal perception. This occurs when a message or stimulus is presented below the absolute threshold, which refers to the minimum amount of stimulus energy required to be detected 50% of the time. Subliminal messages are received, but the individual is not consciously aware of them.
Research has indicated that subliminal messages have little effect on behavior outside of controlled laboratory settings, contrary to some popular beliefs. A related concept is the just noticeable difference (jnd) or difference threshold, which deals with how much difference in stimuli is required to detect a difference between them and which changes depending on stimulus intensity.
