“…This distal versus projected distinction has been made often in the visual perception literature (Arend & Goldstein, 1990; Carlson, 1960; Changizi & Widders, 2002; Gibson, 1950; Gilinsky, 1955; Gillam, 1998; Mack, 1978; Palmer, 1999; Rock, 1983; Sedgwick & Nicholis, 1993), and perception of projected size (as opposed to distal size) has been observed a number of times over the history of visual perception (Angell, 1974; Baird, 1968; Biersdorf, Ohwaki, & Kozil, 1963; Carlson, 1960, 1962; Craig, 1969; Daniels, 1972; Foley, 1972; Gibson, 1950; Gilinsky, 1955; Gogel & Eby, 1997; Jenkin & Hyman, 1959; Joynson, 1949; Kaneko & Uchikawa, 1993, 1997; Komoda & Ono, 1974; Leibowitz & Harvey, 1969; Lucas, 1969; Mack, 1978; McCready, 1965, 1985, 1986; McKee & Welch, 1989, 1992; Ono, 1966; Over, 1960; Plug & Ross, 1994; Reid, 1813; Rock & McDermott, 1964; Sedgwick, 1986; Sedgwick & Nicholis, 1993). Researchers have also shown that observers make qualitatively very different “size” judgments when given projected size instructions compared to when given distal size instructions (Biersdorf et al, 1963; Carlson, 1960, 1962; Gilinsky, 1955; Jenkin & Hyman, 1959; Leibowitz & Harvey, 1969): For stimuli with cues to the distal size, projected size instructions lead to judgments closely matching projected size, and distal size instructions lead to judgments closely matching distal size.…”

Perceiving the Present and a Systematization of Illusions

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called "perceiving the present," that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity.

“…When the subjects grasp the middle chip, there is only one middle chip, surrounded by either smaller or larger chips. When they are judging the size of the middle chip, however, they are comparing two chips -one surrounded by smaller chips, the other by larger ones (Pavani et al 1999, Franz 2001, 2003, Franz et al 2000, 2003, see also Gillam 1998, Vishton 2004and Vishton and Fabre 2003, but see Haffenden andHaffenden et al 2001 for a response). See Briscoe 2008 for a good philosophically sensitive overview of this question.…”

Trompe l’oeil and the Dorsal/Ventral Account of Picture Perception

While there has been a lot of discussion of picture perception both in perceptual psychology and in philosophy, these discussions are driven by very different background assumptions. Nonetheless, it would be mutually beneficial to arrive at an understanding of picture perception that is informed by both the philosophers' and the psychologists' story. The aim of this paper is exactly this: to give an account of picture perception that is valid both as a philosophical and as a psychological account. I argue that seeing trompe l'oeil paintings is, just as some philosophers suggested, different from other cases of picture perception. Further, the way our perceptual system functions when seeing trompe l'oeil paintings could be an important piece of the psychological explanation of perceiving pictures.

“…Despite contrary evidence, the SDIH has endured. Gillam (1998) speculates that the simplicity with which the hypothesis is portrayed, that is, as a geometric relationship between size and distance given a visual angle, may have contributed to its survival. Seeing the conflicting evidence arising from research directed at the SDIH, Gillam (1995) questioned whether size is a quantity derived from distance information, as contended by the SDIH, or a primary perceptual quality like motion.…”

A Binocular Information Source for Size Perception

For too long, size perception research has been guided by the size distance invariance hypothesis. Although research to validate this hypothesis has been largely inconclusive, the hypothesis has endured, perhaps in part because alternative information sources for size perception were lacking. Here, I propose a binocular information source for size perception. The model, drawing on the binocular geometry of viewing a physical extent, is expressed solely in terms of four angular measures and interocular distance, with the explicit exclusion of egocentric distance information. Thus, the proposed information source, if utilized by the binocular system, should be able to augment the few existing sources of information for size perception (e.g., familiar size, texture gradient, and horizon ratio).
