Ames Room (Philip Zimbardo)
Summary
TLDRThis video explains how our perception of size can be easily manipulated through visual cues. At the Exploratorium in San Francisco, the presenter demonstrates how a distorted room alters our perception. Initially, the person appears to grow larger as they move, but the illusion is due to the room's unusual design. There are no right angles, and the ceiling and floor slope, tricking the brain into thinking the person is changing size. This experiment reveals how our brains rely on experience and assumptions to interpret visual information, even when it's misleading.
Takeaways
- 🎥 The video discusses how perception can be manipulated through visual cues.
- 🧒 The narrator recalls childhood fantasies of becoming larger when confronted by bigger kids.
- 🏛️ The Exploratorium in San Francisco is highlighted as a place where perception experiments can be experienced.
- 👁️ The initial impression of the narrator's size is normal due to the limited visual context.
- 💡 As the camera pulls back, the brain re-evaluates and perceives the narrator as smaller based on new visual information.
- 📏 The brain combines the visual data with prior knowledge about room shapes and sizes, usually assuming rooms are rectangular with right angles.
- 🚶♂️ When the narrator moves across the room, it appears as though they are growing larger, despite this being an illusion.
- 🔄 The illusion is demonstrated again, revealing that the room is not rectangular but distorted.
- ⏰ Objects in the room, like clocks, are also distorted to maintain the illusion of normalcy from the original perspective.
- 📐 The room's sloping floor and ceiling contribute to the misperception of the narrator's size, as distance is misjudged.
Q & A
What is the main theme of the video script?
-The main theme is how our perception of size can be manipulated by altering visual and environmental cues, such as in a distorted room, as demonstrated at the Exploratorium Science Museum in San Francisco.
How does the speaker in the video make themselves appear smaller or larger?
-The speaker manipulates the audience’s perception by positioning themselves in a distorted room. The audience misperceives their size due to the room’s unusual angles, slopes, and the brain’s assumptions based on prior knowledge of typical rectangular rooms.
Why does the brain initially perceive the speaker as normal-sized?
-When the speaker is first seen, the brain doesn’t have enough information about the environment and assumes the room is a normal rectangular space, leading to the perception that the speaker is of regular size.
What happens when the lights come up and the camera pulls back?
-When the lights come up and the camera pulls back, the brain receives new visual information, which alters the initial perception and makes the speaker seem much smaller.
Why does the brain interpret the speaker as growing when they move to another part of the room?
-The brain believes the speaker is growing because it assumes the distance between the viewer and the speaker remains constant across the room. Since the room is distorted, this assumption is incorrect, but the brain relies on typical room shapes to make sense of the scene.
What kind of assumptions does the brain make about rooms, and why are they important?
-The brain assumes that rooms are rectangular with right angles. This assumption is important because it helps the brain interpret visual information in everyday settings, but in this case, it leads to a misperception due to the distorted environment.
What role does perspective play in the size misperception?
-Perspective plays a critical role because the distorted room alters the viewer’s perception of distances and sizes. Objects and people appear larger or smaller depending on their position in the room, due to the sloping floor and ceiling.
How does the shape of the room affect the perception of the two clocks mentioned in the video?
-The distorted room makes the large oval clock and the small circular clock appear the same size from one perspective, even though they are physically different. This happens because the room’s unusual angles trick the brain into interpreting them as identical in size.
What is the significance of the room’s sloping floor and ceiling?
-The sloping floor and ceiling contribute to the visual illusion by altering the viewer’s perception of depth and distance. This creates the false impression that the speaker is growing or shrinking as they move within the room.
Why is there no logical explanation for the size changes the audience perceives?
-There is no logical explanation because the perceived size changes are a result of visual misperception, not actual changes in size. The brain tries to make sense of the distorted environment based on past experiences with regular room shapes, but this leads to a faulty interpretation.
Outlines
🎥 Perception through Camera Tricks
The speaker introduces a scenario from childhood where one might fantasize about becoming bigger in response to bullying. They claim that this fantasy is now achievable at the Exploratorium, San Francisco's Science Museum, through manipulation of perception. The illusion relies on the brain’s initial assumption about the speaker's size based on a limited view of the room.
🔍 Understanding the Size Illusion
As the camera pulls back, the audience is shown that the speaker appears smaller due to their brain’s recalculation of size relative to the room. The brain processes the visual cues, including the size and shape of the room, which it assumes to be rectangular and containing right angles. This misinterpretation leads the brain to believe that the speaker is growing when they walk across the room.
🔄 Revealing the Distorted Room
The speaker explains that the illusion is due to a highly distorted room, lacking the expected right angles and rectangular shape. This distortion makes objects, such as clocks, appear similar in size from one perspective but drastically different from another.
📐 The Role of Misperception
The illusion is further broken down as the speaker reveals how the sloping floor and ceiling mislead the brain into thinking the speaker is growing when moving to a different part of the room. In reality, the speaker is simply further away, but the brain’s misinterpretation of distance and size leads to the perception of growth.

Highlights
Introduction of perception manipulation at the Exploratorium Science Museum in San Francisco.
Description of a childhood fantasy of suddenly becoming bigger when pushed around by bigger kids.
Revealing that the presenter manipulated the audience’s perception of their size without altering their actual size.
Initial perception of the presenter appearing normal in size due to the room’s context being hidden.
As lights came up and the camera pulled back, the brain reassessed the visual information, making the presenter seem smaller.
Explanation of how the brain interprets room shapes and sizes based on visual and experiential information.
The brain's conclusion that the presenter was growing larger as they moved, due to the lack of perceptual alternatives.
The room’s true nature revealed: it is distorted with no right angles, not rectangular as perceived.
A large oval clock appears the same as a small circular clock from a specific perspective due to room distortion.
The room’s floor slopes upward and the ceiling slopes downward, contributing to the optical illusion.
Clarification that the presenter isn’t actually growing in size, but is perceived to be due to the brain's misinterpretation of distance.
The visual illusion is driven by the brain’s expectation that the distance between the presenter and the audience remains constant.
In reality, the presenter is twice as far away at one point in the room, creating the size misperception.
Emphasis on how common visual and perceptual cues can be misinterpreted in unfamiliar or distorted environments.
Final explanation of the room’s distortions and how these visual tricks impact our perception of size and space.
Transcripts
lights camera perception
when you were little and some big kids
pushed you around
did you ever fantasize about becoming
bigger all of a sudden
well I did and now I can at the
Exploratorium San Francisco's Science
Museum
how did I do it the easy way by
manipulating your perception when you
first saw me I appeared to be normal
size because you couldn't see the rest
of the room
but as the lights came up and the camera
pulled back your brain performed a new
instantaneous analysis it now saw me as
small
it added up all the visual information
it had
about my size and the size and shape of
the room
and then it added in everything it knew
from experience about the usual shape of
rooms that they're rectangular and have
right angles
so when I walked over here your brain
was convinced I was growing incredibly
large because there was no other
perceptual explanation even though it
wasn't logical
let's look at it again only this time
from a different perspective
the room is not rectangular at all it's
totally distorted there are no right
angles anywhere so that makes this clock
which is large and oval look the same as
that clock which is small and circular
from your other perspective
floor slopes upward and as you can see
the ceiling slopes downward
so I'm not getting larger at all
You're Just misperceiving My Size
because you think that you're the same
distance from me when I'm over here as
you are from me when I'm over there
but in fact I'm twice as far away
