(1999) Isabel Villafuerte 695563 Melbourne University Abstract The ability to perceive lightness is a key component in completing everyday tasks. However, due to the variations in illumination and context, lightness perception theories fail to fully explain lightness perception for all situations. The anchoring theory of lightness perception (Gilchrist et al., 1999) successfully provides a theory that explains the accurate yet systematic inaccuracies of human lightness perception under vast conditions (Murray,2013). These conditions are governed by frameworks, which are groupings of surfaces that belong to each other more or less as determined by 5 factors; Depth, Orientation, Penumbrae, Junctions and Grouping (Gilchrist et al, 1999). However, as anchoring occurs independently within each framework, other theories have been founded which suggest that the human visual system uses the Gestalt laws of perceptual grouping to group regions into factions, known as frameworks, where all regions in the single framework are expected to be illuminated un iformly (Bressan, 2006).

Yet, the process of how humans perceive lightness cannot be understood solely by one theory of lightness perception.
