“…Even though Gogel (1982) has shown that vergence changes occurring as a function of viewers' lateral position are too small to account for illusory concomitant motion, such slight changes in vergence may contribute to viewers' ability to hold one depth organization of a reversible display. Suppose, for example, that divergence occurring at one lateral (or vertical) extreme favored the fusion of the back organization.…”

Three experiments were performed to test whether perceptual organization is cognitively or motiva-tionaUy penetrable. In Experiments l and 2, subjects viewed a reversible stereogram while instructed to hold one depth organization. Responses about depth were recorded indirectly by recording responses about direction of the illusory concomitant motion that is perceptually coupled to depth in a stereogram.

“…An example of triangulation is the use of binocular convergence in the perception of distance; sensing of the vergences of the two eyes, both fixated on a near target, is used by the visual system to estimate the target's egocentric distance (Foley, 1980). Gogel (1974Gogel ( , 1982 was probably the first to develop a triangulation method for measuring perceived egocentric distance (see also Gogel, 1990Gogel, , 1993Gogel, Loomis, Newman, & Sharkey, 1985). His method, depicted in Figure lB, involves movement of the observer's head and the observer's judgment of any apparent movement of the target that there might be.…”

Two triangulation methods for measuring perceived egocentric distance were examined. In the triangulation-by-pointing procedure, the observer views a target at some distance and, with eyes closed, attempts to point continuously at the target while traversing a path that passes by it. In the triangulation-by-walking procedure, the observer views a target and, with eyes closed, traverses a path that is oblique to the target; on command from the experimenter, the observer turns and walks toward the target. Two experiments using pointing and 3 using walking showed that perceived distance, averaged over observers, was accurate out to 15 m under full-cue conditions. For target distances between 15 and 25 m, the evidence indicates slight perceptual underestimation. Results also show that observers, on average, were accurate in imaginally updating the locations of previously viewed targets.The term visual space (or visually perceived space) refers to a perceptual representation of the immediate physical environment that exists independently of any of the particular spatial behaviors it helps to control. Much vision research has been devoted to establishing the functional properties of visual space and the mechanisms that underlie it. A major goal of such research has been to characterize the mapping from physical to visual space under different conditions of information availability, but ultimately the goal must be to predict visual space solely in terms of its sensory inputs and internal determinants (e.g., intrinsic noise, observer assumptions, etc.).Because visual direction is perceived accurately, most space perception research has examined the perception of egocentric distance (i-e., the distance from the object to the observer) and the perception of exocentric distance (i.e., the distance between two targets lying in the same visual direction or, more generally, the distance between any two locations). Because we believe that the perception of egocentric Gogel, 1977), our focus here is on the former.It generally is accepted that when visual cues to distance are reduced greatly, egocentric distance is misperceived (e.g., Baird, 1970;Da Silva, 1985;Foley, 1977Foley, ,1980Foley & Held, 1972;Gogel, 1974;Holway & Boring, 1941;Kiinnapas, 1968;Philbeck & Loomis, 1997;Sedgwick, 1986). Under "full-cue" conditions, in which a stimulus-rich environment is viewed under good illumination, however, there is little agreement about whether perception is accurate, mainly because of the diversity of findings stemming from different experimental methods. With respect to egocentric distance, much of the research conducted under full-cue conditions suggests that perceived distance is nearly linear in physical distance and appropriately scaled, at least for targets within 20 m (e.g., verbal reports, Da Silva, 1985;Sedgwick, 1986;Teghtsoonian & Teghtsoonian, 1969, 1970 blind walking to previewed targets, Corlett, Patla, & Williams, 1985;Elliott, 1986Elliott, , 1987Elliott, Jones, & Gray, 1990;Loomis, Da Silva, Fujita, & Fukusima, 1992...
