Sensory threshold definition psychology
WebA stimulus reaches a physiological threshold when it is strong enough to excite sensory receptors and send nerve impulses to the brain: This is an absolute threshold. A message below that threshold is said to be subliminal: The message is processed, but we are not consciously aware of it. WebA threshold (or limen) is the point of intensity at which the participant can just detect the presence of a stimulus (absolute threshold [15]) or the presence of a difference between two stimuli (difference threshold [7] ).
