Abstract : Over the last decade a great deal of experimentation has been reported on both the physiology of the eye and the human response to a variety of periodic and local structural patterns. Whilst such experimentation potentially assists modelling of visual performance, certain of the results have been interpreted as indicating various complexities and non-linearities in the human visual system. It is important for predictive modelling of complex situations to establish how far the visual system may be considered simple and linear. The present report surveys a wide range of physiological data and considers the implications on predictive modelling. It is considered that the majority of available data can be predicted by the use of a simple visual model provided that due allowance is made of local variations of quality factors in the retina.
