Kinetic Frame Effects: Ii. Vista Motion

Abstract

Perception of a three-dimensional kinetic vista resulted when Ss viewed a quadrilaterally moving frame. The frame was a white rectangle continuously expanding and contracting in size, with a black stationary line in the center. Two vista effects were obtained: (1) wall-penetrating AdAb motion, i.e., when Ss focused on the line it oscillated back and forth in a frame which was seen as a hole in the wall and a (2) pyramid effect, i.e., the rectangle became solid resembling a shell of a pyramid, or a “wooden funnel popping out at you” when Ss focused upon it. Vista effects broaden the family of motion perspective phenomena and suggest that the kind of motion perspective depends not only on Gibson's principle of perspective transformations but also on the area of focus.
