Hey, everyone! It's Esabelle and welcome
back to my channel!
Today, I am reporting on weird psychology facts that you may not know. These aren't necessarily hacks
but some do have some application. Don't

And a big
announcement! I just opened a social
media account on the up-and-coming media platform, Vero! So if you have a Vero
account, be sure to follow me there!
And now, it's video time!
Did you know introverts and extroverts
differ not only in their social energy
but also their salivary glands? The part
of the brain that easily becomes
overstimulated in social settings is the
same part that controls salivation.
In one study, when given a drop of lemon
juice, extroverts produced considerably
less saliva than introverts given a drop
of juice.
This is definitely one of the most unexpected facts I learned in my college career!
Scientists believe they have found the
most critical skill for future success.
The skill? The ability to delay
gratification! In other words, successful
people are able to sacrifice short-term
pleasure in order to achieve meaningful
long-term goals that hold greater reward.
In a classic study called the
Marshmallow Study, children who could
wait 15 minutes unsupervised without
eating a marshmallow sitting in front of
them would earn a second marshmallow-
a pretty big challenge for kids!
The study
followed the children's lives and found
that those who waited for the second
marshmallow had healthier relationships,
better grades, and healthier lifestyles
than those who had not waited. So learn
how to hold off on those marshmallows!
You lurch away if you touch a burning hot surface, right?
Turns out, if you touch
a surface that is both cool and warm at
the same time, you will also lurch away.
When you feel cool and warm together, it
creates the illusion of a burning
sensation.This is called the Thermal
Grill Illusion. Why the brain perceives
the sensation this way is still being
debated. I tried this out by alternating
cool and warm popsicles and it actually
worked! This does not cause any real harm, so this also makes a great prank!
Do you want to have limited choices? If
you don't, you're in good company!
But according to multiple studies, more
choices can actually overwhelm you and
make you more unhappy, especially if you
must choose only one or a few of
something among numerous options, like
choosing a snack. For more important
decisions, you are also less likely to make a wise choice when confronted with multiple options.
When there are few or
even no choices, you make better
decisions and feel happier about them.
Pretty surprising, right?
Nurse: "This may sting a little..."
The Placebo Effect is a widely known psychological
effect, but did you know there is an
opposite phenomenon called the Nacebo Effect?
You will feel pain when there is
none if it is suggested that you will feel it.
Even once you are informed that
no pain was really involved, you may
still feel residual pain, tingling, or
numbness, as if pain had actually been involved.
This is a pretty common
occurrence, and now you know the name of it! 😉
Traditional lie detectors work by
measuring heart rate.
Now scientists may have developed a more accurate form of lie detector!
This one works by detecting bodily movements, especially eye movement. You actually fidget more when
you're lying, though these motions are subtle and difficult to discern with the naked
eye. The new detector picks up these
subtle movements.
Your subconscious mind can discern
emotions based on slight color
differences in the face that occur as
blood oxygen levels change according to
your emotions. These color changes are
slight, and you perceive them on a subconscious level.
A red tint indicates anger; green indicates sadness; and yellow indicates fear.
Paramedics wear special
glasses called Oxy-Amp Vein Glasses that
allow them to discern a patient's blood
flow. Since it emphasizes skin coloration,
it also enhances the ability to perceive emotions.
