Angular Declination and Perceived Distance
In two experiments involving a total of 83 participants, the effect of a vertical angular optical compression on the perceived distance and size of a target on the ground was investigated. Replicating an earlier report (Wallach & O’Leary, 1982), reducing the apparent angular declination below the horizon produced apparent object width increases (by 33%) consistent with the perception of a great...
متن کاملDepth compression based on mis-scaling of binocular disparity may contribute to angular expansion in perceived optical slant.
Three studies, involving a total of 145 observers examined quantitative theories of the overestimation of perceived optical slant. The first two studies investigated the depth/width anisotropies on positive and negative slant in both pitch and yaw at 2 and 8 m using calibrated immersive virtual environments. Observers made judgments of the relative lengths of extents that were frontal with thos...
متن کاملPerceived shape and its dependency on perceived slant.
Koffka's suggestions that perceived shape and perceived slant "will be coupled together so that if one changes, the other changes also" and that errors in perceived shape vary as some function of errors in perceived slant were examined. Ss described, by means of appropriate response mechanisms, the shapes and slants of trapezoids. Shape and slant responses were made both monocularly and binocul...
متن کاملThe perceived slant of visual surfaces-optical and geographical.
One of the properties of a visual surface along with hardness, distance, and color-with-illumination, is that of slant. This term must be understood to include not-slanted as well as slanted; in other words the variable consists of opposite qualities having zero slant as a norm. There is evidence that optical slant, so-called, is determined by stimulation. When vision is monocular and the head ...
متن کاملDirect manipulation of perceived angular declination affects perceived size and distance: a replication and extension of Wallach and O’Leary (1982)
In two experiments involving a total of 83 participants, the effect of vertical angular optical compression on the perceived distance and size of a target on the ground was investigated. Replicating an earlier report (Wallach & O'Leary, 1982), reducing the apparent angular declination below the horizon produced apparent object width increases (by 33 %), consistent with the perception of a great...
