Abstract
In our everyday live we experience many conflict situations. In this work three different types of conflict are presented: Binocular rivalry, Stereopsis and Attention. Binocular rivalry ensues when both eyes are confronted with two sufficient different pictures. This is resolved by a temporal segregation of both pictures in awareness. The pupil reacts to a change in perceived brightness and does so earlier as an actual behavioral report. The pupil is an indicator for upcoming rivalry shifts. Under normal viewing condition the visual system is provided by many different depth cues, as disparity and perspective. A combination of cues, indicting for the same or different spatial orientation, revealed, that cues are used to estimated depth; without regard to a potential antagonism. The visual system is flooded by information. In order to separate relevant and irrelevant data, attention is employed. Neuronal networks are compared between humans and monkeys performing the same task under fMRI.
