Abstract
The size of the suggestion restricted visual field was determined among 3 groups consisting of hypnotized Ss, simulators and “instructed fakers.” Instructions were designed to produce narrowing of the visual field. Visual field size was tested by 3 differently designed perimeters each incorporating a different testing distance. The group data were indistinguishable from each other. Some Ss in each group exhibited field sizes which would have been expected if they were suffering from a true scotoma. Other Ss responded as if the functioning area of the visual field were a real object, while still other Ss produced intermediate functions. Implications for theory and for visual field testing are discussed.Keywords
