In subliminal stimuli research, the threshold is the level at which the participant is not aware of the stimulus being presented. [9] Researchers determine a threshold for the stimulus that is used as the subliminal stimulus.

Here, the critical parameter is the time interval (the SOA) between the onset of the subliminal stimulus and the onset of the masking stimulus. [1] In psycholinguistics the stimuli are typically a prime and a target, in which case the stimulus-onset asynchrony is measured from the beginning of the prime (S1) until the beginning of the target (S2).
Modern medical and psychological investigations into consciousness are based on psychological experiments (including, for example, the investigation of priming effects using subliminal stimuli), [92] and on case studies of alterations in consciousness produced by trauma, illness, or drugs.

where is the original intensity of the particular stimulation, is the addition to it required for the change to be perceived (the JND), and k is a constant. This rule was first discovered by Ernst Heinrich Weber (1795–1878), an anatomist and physiologist, in experiments on the thresholds of perception of lifted weights.
