- Ames room
An Ames room is a distorted room that is used to create an
optical illusion. Probably influenced by the writings of Hermann Helmholtz, it was invented by American ophthalmologist Adelbert Ames, Jr.in 1934, and constructed in the following year.
An Ames room is constructed so that from the front it appears to be an ordinary cubic-shaped room, with a back wall and two side walls parallel to each other and perpendicular to the horizontally level floor and ceiling. However, this is a trick of perspective and the true shape of the room is
trapezoidal: the walls are slanted and the ceiling and floor are at an incline, and the right corner is much closer to the front-positioned observer than the left corner (or vice versa).
As a result of the optical illusion, a person standing in one corner appears to the observer to be a giant, while a person standing in the other corner appears to be a dwarf. The illusion is convincing enough that a person walking back and forth from the left corner to the right corner appears to grow or shrink.
Studies have shown that the illusion can be created without using walls and a ceiling; it is sufficient to create an apparent horizon (which in reality will not be horizontal) against an appropriate background, and the eye relies on the apparent relative height of an object above that horizon.
An Ames room is depicted in the 1971 film adaptation of the
Roald Dahlnovel " Charlie and the Chocolate Factory". Also, production of " The Lord of the Rings" film trilogy used several Ames room sets in Shire sequences to make the heights of the hobbits correct when standing next to Gandalf. The 1960s television show "Voyage to the Bottom of the Sea" used an Ames room in one episode to show, rather than just declare, an attempt to make two characters (one standing on each side of the room) lose their minds.
A type of selective perceptual distortion known as the
Honi phenomenoncauses some married persons to perceive less size distortion of the spouse than a stranger in an Ames room.
The effect was related to the strength of love, liking, and trust of the spouse being viewed. Women who were high positive in this area perceived strangers as being more distorted than their partners. Size judgements by men did not seem to be influenced by the strength of their feeling toward their spouse.

Further study has come to the conclusion that the
Honi phenomenondoes not reliably exist as first thought, but may be explained as sex difference influencing perception, with women interpreting a larger reading as a more meaningful or valuable perception of things than men's.
