D)subliminal

Question

Quizplus · Accepted Answer

The difference threshold (also known as the just noticeable difference or JND) is the minimum difference in stimulus intensity required for an observer to detect a change in sensation. It determines the smallest detectable difference between two stimuli, and it varies depending on the magnitude of the stimulus being compared. In contrast, absolute threshold refers to the minimum intensity of a stimulus that can be detected by an observer, while adaptability threshold refers to the ability of the senses to adjust to changing environmental conditions. Subliminal threshold refers to the point below which a stimulus is too weak to be consciously perceived, but may still influence behavior or cognition unconsciously.
