About Beau Lotto
Beau
Lotto is a neuroscientist who specializes in sense perception. He is also the
founder of Lottolab, a studio that blends art and science to explore how we
view and interact with the world. He also helped publish the first
peer-reviewed scientific paper by school children.
Why is this talk worth watching?
Lotto’s
visual illusions are – literally – unbelievable. They also demonstrate just how
much our sensory knowledge depends on context, a key concept to grasp.

What is BL’s key idea about sensory
information?
|
BL
talks about how we cannot trust what we see as the sensory information is not
trustworthy as our minds are not developed enough to understand anything to
its fullest extent. There is no inherent meaning in information, but its only
what we do with it that matters. We see by learning to see.

So how do we see?
|
We see by learning to see. The brain evolved
the mechanisms for finding patterns (relationships in information) and
associating it with a behavioral meaning. An example of this can be found in
letter strings in language.

How does changing the context change what
we perceive in his illusions?
|
It means you could take two identical
things, put each in either a light or dark surrounds, and the one on the dark
surround looks lighter than the one on the light surround.

What is the significance of the optical
illusions demonstrated by BL?
|
The brain evolved to see the world the
way it was useful for the human race to see in the past.

How has BL extended the principles of
what he does?
|
He did an experiment of which he
translated light into sound, enabling people to hear their visual world,
navigating the world using their ears. This was done in order to aid people with
blind or hard-seeing people, but also to try and figure out how people make
sense of their world. He also got a child to listen to an orchestra and paint
it, as a way of trying to understand how we visually see sound.

What does BL say about our relationship
with nature?
|
He states that we are defined by our
environment and our interactions with it (our ecology). He then states that
it is, “necessarily historical, empirical (observation), and relative”.

knowledge questions and discussion points

Can
we trust our senses?
Basing the answer
to his question off of BL’s talk, we cannot trust our senses because we do not
fully understand the world we live in fully, meaning that our interaction with
it cannot be fully understood as well. It truly relates to the last question,
of which our relationship with nature comes from an interaction with it; it is
empirical. To summarize, we were born with five senses given to us by nature in
order to navigate through the world (i.e. sensing pain, temperature change, etc.…)
·
Is
seeing believing?
Well, visual
illusions can distort our perception so we can say that what we “see” is not
what is physically there. An example of this can be seen when BL had conducted
various experiments with color to the audience. However, an example of mine own
is that in the optical illusion below, where the image itself is not animated
yet it has movement that is caused by the specific placement of colors and
shapes (i.e. small dots at the center create the illusion that the picture is
farther away from us, whilst the edges do the opposite effect). Furthermore,
belief of historical events, or meanings of certain things are made to demonstrate
that visual belief is just an interpretation, not actual sight. It’s a
confusing concept, but then again you have to ask yourself if blue is actually
blue? We only know blue itself because we have classified it, and we choose to
see it as blue.
·
What are implications of the flawed way in
which we view the world?
This is a difficult
question, because it asks to draw a conclusion as to what the effect of seeing
a ‘flawed’ view of the world is. Of course, a significant disadvantage is that
every human develops a certain distrust in their surroundings and therefore it
can affect the psyche of the person in a negative way. For example, a person
might have absolutely no faith in what is around them that they will (at least
mentally) cease to find meaning in their life. As, our surroundings form
experiences with our interactions with it, and so it waters our perception of
life. Another implication is that we know less of our world, meaning that
humans are limited to understanding our world from a perspective that is
unbiased as our own personalities are shaped with the nature of which we were
brought in, meaning that almost all decision is influenced by our emotions and
rational way of thinking. Of course, these are merely guesses.
