Existing or occurring outside the threshold of consciousness or perception; beyond the limits of awareness.
From Latin 'extra' (outside) + 'liminal' (relating to a threshold, from 'limen' meaning threshold). This psychological term emerged in the early 20th century to describe subliminal phenomena.
Extraliminal stimuli—like sounds too quiet to hear or colors beyond your eye's range—exist all around us, yet some research suggests your brain might process them even though you're unaware!
