Space - Time - Colour

The wiewer submitted to the tests perceives abstract painted forms - which do not recall objects from the surrounding world - as if they get detached from the space, with depths that gradually increase within an interval up to several minutes. This time obviously exceeds that necessary to normally perceive objects in space. This "dynamics" does not occur by modifying the vanishing lines, since objects which are closer or farther from the viewer are perceived in motion. One may say that psycho-physiological mechanisms have not undergone such an experience and that they are not trained.
This is also proved by the fact that the adaptation time gradually decreases when the test is repeated. However, that time is much higher than the time of adaptation to the normal observation of the surrounding space, when we succesively stare at closer or more distant objects. In this respect, the rapid grasping of depth differences does not seem to occur.
Space asociated to a time, which does not result from an objectual movement, seems to be perceived in this case following nonconditioned reflexes, which acouire awareness by comparison with space and time already assimilated.
another effect for which viewers are not trained is the coloured fusion, an effect amplified by a back outline surrounding coloured fields or by marks of the same shade. This resulted in the so-called psychophysical mixture of the colours.
One is no longer aware of this effect by comparison with elements from assimilated representations, but from a non-conditioned reflex. The resulting colour is fluctuating hallucinating, with nacreous shades.
The author`s tests prove that it is more efficient to include the psychological test in a composition than use it isolatedly. In visual arts, communication by emotional pathways should prevail, restricting elements that lead to rational interpretations.
