“…It has long been known that the HVI is sensitive to the "frame" ofthe visual field around the target (Kiinnapas, 1955(Kiinnapas, , 1957(Kiinnapas, , 1959. Indeed, a strong case can be made that the tendency for verticals to appear longer than horizontals across a wide range ofconditions reflects the intrinsic shape of the visual field, which is wider than it is high (e.g., Prinzmetal & Gettleman, 1993). The typical explanation is that length is perceived relative to this frame.…”

“…Because the visual field is wider than it is high, people may tend to experience greater horizontal than vertical extents. With binocular viewing, the visual field is ovoid, its horizontal axis being nearly half again greater than its vertical axis, about 200 0 versus 130 0 (see Prinzmetal & Gettleman, 1993). If, as a result of this asymmetry, people are exposed on average to greater horizontal than vertical extents, the long-term discrepancy in the distribution of horizontal and vertical percepts might induce a differential effect on the perception ofverticals and horizontals, enhancing the former relative to the latter and thereby producing the HVI.…”

“…Similarly, both the Zöllner and the Ponzo illusions are greater in the vertical than in the horizontal orientation (Fisher, 1968b(Fisher, , 1973Oyama, 1975). We do not know the cause of this difference, but it may be related to other anisotrophies in the visual field (Prinzmetal & Gettleman, 1993). Of course, these similarities may simply be a coincidence, and the misperception of length in the Ponzo illusion might be unrelated to orientation perception.…”

“…We expected that the vertical lines would be judged longer than physically equal horizontal lines (HVI). We also expected that the size of the HVI would lie between 9% and 15%, a range reported in earlier studies (Armstrong & Marks, 1997;Prinzmetal & Gettleman, 1993). Finally, we had no compelling reason to expect that the size of the HVI would differ in the two eyes.…”
