The paper suggests a new view on the classical work by W. Metzger (1930), Optische Untersuchungen am Ganzfeld, that first experimentally investigated the perceptual experience for an observer in a homogeneous field of stimulation (Gan-zfeld). The work is generally discussed for its implications in space perception theories. In the present paper, the reports referred by Metzger are approached from a different perspective, i.e. looking at their contribution in answering a fundamen-tal question about the minimum perceptual organization: is it possible to defini-tively erase variation and opposition from our perceptual experience? The analysis reveals that variations developed along dimensions of opposition are still present to shape our perceptual experience even when an absolute invariance is reached at the stimulation level.

Abstract
The paper suggests a new view on the classical work by W. Metzger (1930), Optische Untersuchungen am Ganzfeld, that first experimentally investigated the perceptual experience for an observer in a homogeneous field of stimulation (Gan-zfeld). The work is generally discussed for its implications in space perception theories. In the present paper, the reports referred by Metzger are approached from a different perspective, i.e. looking at their contribution in answering a fundamen-tal question about the minimum perceptual organization: is it possible to defini-tively erase variation and opposition from our perceptual experience? The analysis reveals that variations developed along dimensions of opposition are still present to shape our perceptual experience even when an absolute invariance is reached at the stimulation level.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
