Perception of contrariety is approached from the point of view of information theory, testing the degree of information potential present in contrary, similar and different geometrical patterns. For the first time we see contrariety dealt with as a perceptual datum which can be analyzed using the change detection paradigm. This reinforces the results from protocols and experiments using phenomenal tasks, and provides new indications based on detection performance and reaction times. For the very reason that tachistoscopic presentation times are used, the study confirms that contrariety is a direct, immediate component of perception and is identified and processed by the perceptual system in a significantly independent way with respect to other kinds of transformations.

Abstract
Perception of contrariety is approached from the point of view of information theory, testing the degree of information potential present in contrary, similar and different geometrical patterns. For the first time we see contrariety dealt with as a perceptual datum which can be analyzed using the change detection paradigm. This reinforces the results from protocols and experiments using phenomenal tasks, and provides new indications based on detection performance and reaction times. For the very reason that tachistoscopic presentation times are used, the study confirms that contrariety is a direct, immediate component of perception and is identified and processed by the perceptual system in a significantly independent way with respect to other kinds of transformations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
