Of course, the autokinetic invariance is not to be interpreted as a manifestation of harmonie preetablie between species.
Positions of these horizons on physical scales of length (space) and duration (time) may be approximately related by the autokinetic invariance (Section 2.3).
(24) If this is the case, another interesting question would be whether there are invariance relations between space and time scale constants, holding at the outer horizons of spatial and temporal experience, similarly to the autokinetic invariance relation holding at the inner horizons.
This concept reminds us of Minkowski's (1909) famous words on "space by itself, and time by itself, vanishing into shadows and only a kind of union of the two being preserved." (25) Assuming the spatio-temporal matrix of organic life as the unitary basis of space and time, we realize the need for an integrative discipline transcending classical psychophysics, a kind of "ethophysics" or "ecophysics." In this integrative discipline, observational regularities such as, for example, the above-stated autokinetic invariance may play a role similar to the "laws" in the traditional psychophysics.
The classic laboratory experiment that mimics this process is Sherif's studies of the "autokinetic effect," an optical illusion in which a point of light shining in a darkened room appears to move, but actually does not.(112) In one version of these experiments, several subjects are brought together and asked individually to judge how far the spot of light moves in a two-second interval when the light is turned on and off.
For example, Sherif's (1937) studies of the autokinetic effect examined the emergence of group norms in an ambiguous situation.
