A square composed of horizontal lines appears taller and narrower than an identical square made up of vertical lines. Reporting this illusion, Hermann von Helmholtz noted that such illusions, in which filled space seems to be larger than unfilled space, were common in everyday life, adding the observation that ladies' frocks with horizontal stripes make the figure look taller. As this assertion runs counter to modern popular belief, we have investigated whether vertical or horizontal stripes on… Expand

Helmholtz Versus Haute Couture: How Horizontal Stripes and Dark Clothes Make You Look Thinner
TLDR
Results showed that horizontal stripes and lower luminance have—independently—a small-to-moderate thinning effect on the perceived size of the body, and the effect is larger when the two variables are combined. Expand
Helmholtz illusion makes you look fit only when you are already fit, but not for everyone
A square filled with horizontal stripes is perceived as thinner than one with vertical stripes (Helmholtz illusion). This is not consistent with a common belief that horizontally striped clothingExpand
Wall patterns influence the perception of interior space
TLDR
It is concluded that object-based texture effects cannot be generalised to interior space perception, and for a room’s perceived spatial extent, pattern density is more important than pattern orientation. Expand
Crossing the line: estimations of line length in the Oppel-Kundt illusion.
TLDR
This work systematically investigated the effects of adding 1 to 12 ticks on perceived line length and results suggest that at least three mechanisms must be at work: bisection, which reduces perceived length, a filled extent effect, and a local contour repulsion effect of the penultimate tick upon the perceived position of the end tick.

Directional organization and shape formation: new illusions and Helmholtz's Square
  • B. Pinna
  • Computer Science, Medicine
  • Front. Hum. Neurosci.
  • 2015
TLDR
The aim of this work is to solve the antinomy between the two sets of illusions and to demonstrate a common explanation based on the interaction between different sources of directional organization, by introducing some new phenomena and through phenomenological experiments proving the role played by the directional shape organization in shape formation. Expand
Illusions of filled extent : psychophysics and neuroimaging methods
The aim of this thesis is to shed light on the Oppel-Kundt, vertical-horizontal and Helmholtz’s squares illusions. Eleven psychophysics experiments and one final fMRI study were conducted in order toExpand
An Orientation Dependent Size Illusion Is Underpinned by Processing in the Extrastriate Visual Area, LO1
TLDR
The results demonstrate the involvement of a specific extrastriate area in an illusory percept of size, consistent with previous research that LO1 plays a role in the processing of orientation information. Expand
The open-object illusion: size perception is greatly influenced by object boundaries
  • T. Makovski
  • Psychology, Medicine
  • Attention, perception & psychophysics
  • 2017
TLDR
It is suggested that the visual system extends the missing boundaries of open contour objects, which results in an overestimation of the object’s size, suggesting that filled space sometimes shrinks, rather than inflates, the perceived size of an object. Expand
Darks and Stripes: Effects of Clothing on Weight Perception
TLDR
This work concludes that dark clothes indeed decrease perceived weight slightly but statistically significantly, and horizontal stripes have no discernible effect compared to solid light-colored clothes, and gives an outlook on the vast opportunities of using crowd sourcing in the modern fashion industry. Expand
The vertical-horizontal illusion: assessing the contributions of anisotropy, abutting, and crossing to the misperception of simple line stimuli.
TLDR
This work has shown that this bisection component confounds two effects: One when lines cross one another and a second effect when one line abuts another. Expand

Shrinkage in the Apparent Size of Cylindrical Objects
TLDR
The illusion demonstrated here suggests that the visual system may determine the size of 3-D objects by accounting for their depth structures, and inappropriately triggered by pictorial depth cues may be irrelevant. Expand
Some Observations on Gregory's Theory of Perceptual Illusions
  • M. Zanforlin

Gregory (1963, 1965, 1966) has explained the optical iIlusions of the Muller-Lyer type as a misapplication of a perceptual mechanism which he calls “primary constancy scaling.” This mechanism isExpand
Task and size effects in the Oppel-Kundt and Irradiation illusions.
The present study examined the effects of type of task and stimulus size on two well-known illusions of perceived size: the Oppel-Kundt illusion and the Irradiation illusion. In Experiment 1, aExpand
Perception of three-dimensional shape from texture is based on patterns of oriented energy
TLDR
It is found that correlated changes in oriented energy along lines corresponding to the lines of maximum and minimum curvature of the surface are crucial for conveying the three-dimensional shape of thesurface. Expand

TLDR
The key results are that mean adult IPD is around 63mm, the vast majority of adults have IPDs in the range 50-75 mm, the wider range of 45-80 mm is likely to include (almost) all adults, and the minimum IPD for children (down to five years old) is around 40 mm. Expand
Patterns of eye movements when male and female observers judge female attractiveness, body fat and waist-to-hip ratio
Behavioural studies of the perceptual cues for female physical attractiveness have suggested two potentially important features: body fat distribution [the waist-to-hip ratio (WHR)] and overall bodyExpand
