Abstract
Problem: Plastics Rorschach Stimuli (PRS) were produced through the same randamization procedure as the Rorschach figures. Ego functions of the blind may be studied by the use of PRS to which even the complete blind can respond. Method: Subjects of normal visual acuity are 39 (22 males) and blind subjects 24 (20 males). Results: Differences between the eye mask condition and visual condition and between the group of normal visual acuity and the group of the blind were studied. These two results were compared with each other. Conclusions: PRS is one of the useful means to study the blind's ego functions as well as the roles of dermal sensation and visual perception in ego functions in general.
