Abstract

Prolonged observation of an unchangeable configuration produces adaptation which can be shown by an optical after effects such as the tilt illusions. The

This experience is called inter-ocular transfer (IOT) which is exhibited in MAE (Lehmkuhle and Fox, 1976) and the tilt effect (Campbell and Maffei, 1971). IOT characteristically ranges between 50% and 80% of the influence witnessed when the adapter and the test stimulus are shown to the same eye. There is some doubt cast over the link between IOT of adaptation and cortical binocularity. The after effects between moving patterns and a static one have been demonstrated by a binocular process of motion processing.

If one looks at a motionless test configuration after adjusting to the moving spiral one experiences a MAE that is in the opposed course than the earlier observed illusion. According to Anstis and Gregory (1964) the illusory after effect requires the movement of images across the retinal cones and rods and may co-operate to create MAE. The study carried out suggests an indication that MAE contains both peripheral and central elements. Conflicting evidence has been found in the influence of stimulation in the central versus peripheral visual field and that could be attributed to stimulus size.

Method

There is an interest in finding out if MAE is caused by reduced activity in directionally sensitive retinal ganglion cells. This is assessed through inter-ocular transfer.
