(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)本研究的目的是探讨视觉空间知觉的生成过程，通过描述心理经验，发生在视觉减少的情况下，称为Ganzfeld。我们把我们的注意力集中在动态的“外部世界”和“自我”，这是在这种“空间”的经验，试图分析的阶段，这可能被称为“前空间”，并讨论了报告的经验与相关现象的视觉空间知觉。(2)甘茨菲尔德的心理体验与我们以前的研究基本相似。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变化相对应。结果表明：（1）瞳孔大小的显著变化比亮度的显著变化提前500- 1500 ms。2)除了这些离散的变化，一个渐进的 ...更多信息 在观察的时间过程中观察到持续的瞳孔收缩。3)瞳孔大小的微小波动在观察者报告外部世界和自我之间的现象边界模糊的阶段之后停止。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。5)这些结果是用红光的甘茨菲尔德选择性地获得的。6)尽管不同学科的报告在丰富程度上存在显著差异，但报告的内容和时间变化具有高度的共性。(3)上述一些结果最初是在本研究中获得的，而其他结果（3、5、6）是由首席研究员对先前获得的结果进行重新确认的。必须采取进一步措施，提出一个综合这些调查结果的模式。利用这种模型，可以为视觉空间知觉的生成过程提供有益的启示。(4)所收集的口头报告的原始材料不仅可以用于视觉感知的分析，而且可以用于人格心理学和精神病理学方法领域的讨论。少
