"Webhuman information processing. Following a long tradition in psychology and neuroscience, visual information processing can be described in terms of a two-level model (e.g. [7], [8], [9]). At the first, preattentive level, objects are dynamically localised in the 3D environment – hence the other name for the level, which is ‘ambient’. " - During rapid saccades visual information is
