threshold 

The value of a stimulus that just produces a response. Syn. limen.
absolute threshold The minimum luminance of a source that will produce a sensation of light. It varies with the state of dark adaptation, the retinal area stimulated, the wavelength of light, etc. Syn. light threshold. See photochromatic interval.
contrast threshold See differential threshold.
corneal touch threshold See corneal touch threshold.
differential threshold The smallest difference between two stimuli presented simultaneously that gives rise to a perceived difference in sensation. The difference may be related to brightness, but also to colour and specifically to either saturation (while hue is kept constant) or hue (while saturation is kept constant). The differential threshold of luminance is equal to about 1% in photopic vision. Syn. contrast threshold (if the difference is one of luminance); just noticeable difference (jnd). See Weber's law; contrast sensitivity.
light threshold See absolute threshold.
movement threshold 1. The minimum motion of an object that can be perceived. 2. The speed at which an object moving between two points just appears to be moving. See hyperacuity; phi movement.
resolution threshold See limit of resolution.
stereo-threshold See stereoscopic visual acuity.

Turner goes on to describe the liminal as "an interval, however brief, of margin or limen, when the past is momentarily negated, suspended or abrogated, and the future has not yet begun, an instant of pure potentiality when everything, as it were, trembles in the balance" (qtd.

by resurrecting Quentin Compson and putting him to work re-telling the South's tangled past, William Faulkner set out to accomplish the same regeneration with one of the American South's specific and divided selves: the rationalized walls built between society and the Feminine ethic; without an open border or at least a fertile limen between the base pair out of which all human community radiates, the community stagnates and falls into barrenness--social Waste Land, so to speak.

En este limen formado por el exceso de trascendencia, el tiempo se acrisola al margen tanto de la historia como de la cronologia, y, poco a poco, se va haciendo cada vez mas denso: es el tiempo abstracto del ritual y del sacrificio en el que la existencia humana concreta se funde y se diluye sujeta a ritmos cosmicos que se ve incapaz de controlar.
