title: [Visual imagery and eye movements: effects of projective size of image on eye movements (author's transl)].
abstract: The effects of size of image on eye movements were explored. Eye movements of 18 subjects were recorded by the corneal reflection method. The subjects imagined various objects within an indicated circle of concentric circles presented externally. As the result, two types of the subjects were observed. They were as follows: (a) The majority moved their eyes within the projective angle under the 10 degrees condition and the 30 degrees condition whereas they scarcely showed eye movements under the 1 degrees condition. Asked whether a property of the stimulus belonged to the image, over 60% of the subjects, under the 30 degrees condition, showed a saccade to the proper projected part which might be considered as scanning. (b) Some subjects hardly moved their eyes under any of the conditions.
