(1) The purpose of the present study was to investigate generative processes of the visual space perception by describing psychogical experiences which occur in the visually reduced situation called Ganzfeld. We focused our attention on the dynamism of 'external world' and 'self' which were experienced in this sort of 'space', attempted to analyze the phase which might be referred to as 'prespatial', and discussed reported experiences in connection with related phenomena of visual space perception.(2) Psychological experiences with Ganzfeld were basicly similar to those which had been obtained by our previous studies. In the present study, however, we corresponded those experiences with changes in the pupillary size simultaneously recorded in the process of observation. Results obtained here were as follows : 1) Marked changes in the pupillary size occurred in advance to reported changes in the phenomenal brightness by 500-1500ms. 2) In addition to those discrete changes, a progressive … More ly ongoing pupillary contraction was observed in the time course of observation. 3) Minute fluctuations in the pupillary size ceased after the phase in which an observer repoted ambiguity of the phenomenal boundary between external world and self. 4)Latency to perceiving complete darkness of the visual field was negatively correlated to physical brightness of the field. 5) Those results were obtained selectively with the Ganzfeld of red light. 6) In spite of remarkable differences in richness of reports among subjects, there was a high level of generality for the content and the temporal change of reports.(3) Some of the results mentioned above were originally obtained in the present study, whilst others (3,5,6) were reconfirmed of those obtained earlier by the head investigator. Further step must be taken to propose a model which integrates those findings. With such a type of model, a productive suggestion could be given for generative processes of visual space perception.(4) Raw materials of oral reports collected could be used not only for the analyzes of visual perception but also for the discussion in the fields of personality psychology and psychopathological approach.

(1)本研究的目的是通过描述发生在被称为“甘兹菲尔德”的视觉缩小情况下的心理体验来研究视觉空间感知的生成过程。经历过这种“空间”，试图分析可能被称为“前空间”的阶段，并讨论了与视觉空间感知相关现象相关的报道经验。（2）甘兹菲尔德的心理体验基本上类似于那些然而，在本研究中，我们将这些经验与观察过程中同时记录的瞳孔大小的变化相对应，此处获得的结果如下：1）瞳孔大小发生了显着变化。提前报告的显着亮度变化 500-1500 毫秒 2) 除了这些离散变化之外，在观察过程中还观察到了渐进性的瞳孔收缩 3) 分钟。在观察者报告外部世界与自我之间的现象界限模糊的阶段后，瞳孔大小的波动停止。 4）感知视野完全黑暗的潜伏期与视野的物理亮度呈负相关。 6）尽管受试者报告的丰富程度存在显着差异，但报告的内容和时间变化具有很高的通用性。（3）一些上述结果最初是在本研究中获得的，而其他结果（3,5,6）则由首席研究员先前获得的结果进行了重新确认，必须采取进一步的步骤来提出一个将这些发现与这样的结果相结合的模型。 (4)收集到的口头报告的原始材料不仅可以用于视觉感知的结合，还可以用于人格心理学和心理学等领域的讨论。较少的精神病理学方法。
