feature of the world. In contrast, the apparent size change is not such a strong paradox, because we do have the experience that objects can change size to a certain degree (for example, people and animals can appear to become smaller or larger by crouching or stretching). Honi phenomenon A type of selective perceptual distortion known as the Honi phenomenon causes 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 judgments by men did not seem to be influenced by the strength of their feeling toward their spouse. Further study has concluded that the Honi phenomenon does 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. In media The Ames room principle has been used widely in television and movie productions for special effects when it was necessary to show actors in giant size next to actors in small size. For example, production of The Lord of the Rings film trilogy used several Ames room sets in Shire sequences to make the heights of the diminutively-sized hobbits correct when standing next to the taller Gandalf. When used for special effects, the viewers will not see that an Ames room is being used. However, a few times an Ames room has also been shown explicitly. An Ames room is used in the 1965 TV Special My Name Is Barbra. It enabled the star to shrink before singing a little girl medley, and return to normal size to sing adult songs. An Ames room is depicted in the 1971 film adaptation of the Roald Dahl novel Charlie and the Chocolate Factory. The 1960s television series Voyage to the Bottom of the Sea used an Ames room in the episode "The Enemies" to show, rather than just declare, an attempt to make two characters (one standing on each side of the room) lose their minds. Episode 141 of the first incarnation of the science educational television series 3-2-1 Contact has a segment in which the optical illusion of the Ames Room is demonstrated and explained In
