In this work we demonstrated, in the same scientific spirit as used by Gestalt psychologists, unique and effective properties imparted by contrast polarity in perceptual grouping and figure-ground organization. These unique properties have been demonstrated by putting contrast polarity against the Gestalt principles of visual organization, by extending the phenomenon of amodal completion to a new kind of contour-junction (the so-called I-junction) and, finally by demonstrating new functional effects under limiting conditions. Our result showed the domination of contrast polarity against all the Gestalt principles, T-junctions, and regularity. These results suggest that the reversed contrast accentuates and instills a phenomenal salience that triggers a process of object segregation and figure-ground segregation.

Abstract
In this work we demonstrated, in the same scientific spirit as used by Gestalt psychologists, unique and effective properties imparted by contrast polarity in perceptual grouping and figure-ground organization. These unique properties have been demonstrated by putting contrast polarity against the Gestalt principles of visual organization, by extending the phenomenon of amodal completion to a new kind of contour-junction (the so-called I-junction) and, finally by demonstrating new functional effects under limiting conditions. Our result showed the domination of contrast polarity against all the Gestalt principles, T-junctions, and regularity. These results suggest that the reversed contrast accentuates and instills a phenomenal salience that triggers a process of object segregation and figure-ground segregation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
