Fake It to Make It
Is it possible for an introvert to behave like an extrovert?
Sophie, 11 years old, had secure attachment as a baby, but is shy.
Valentine's card from schoolgirl in her class, "when I think of you, you are
quiet", Sophie is highly self-conscious, she is going to face situations where if
you're an introvert it's not going to work so well, have to do things outside
your comfort zone. Brian Little thinks that if it's rly important then you can
push yourself to be more behaviorally extroverted, but there will be
costs/benefits though. Amy Cuddy, fake it fake it fake it until you become it, it
becomes part of you
Today’s Class:
Is it a good idea to try to appear extroverted if you are actually shy?
How does shyness change across roles or partners and what accounts for the
An Interesting Study: Lippa 1976
PhD student of Darryl Bem;
Followed up participants of Bem 1974 study on consistency of behavior;
Knew subjects standing on E-I;
Also Measured self-monitoring
Cover story: Teaching high school.
2 minute lesson about triangles to 7th graders.
3 X:
Filmed and blind coders rated verbal & nonverbal behavior.
He really knew where they were on the Intro/Extroverted Scale. Students
were called up; he told them it was about teaching styles, asked to make
believe they were teaching 7th graders about triangles talk for a few minutes
about them. Talked about self-monitoring (high or low). He asked participants
to pretend they were shy or extroverted.
Dependent Variables
Stride Length;
Non-verbal Expansiveness;
Eye Contact
Extroverts were rated as extroverted (more than introverts). What happens to
an introvert asked to play an extrovert
Moderating Effect of Self-Monitoring
Low SM = not that much difference, you can act a little different but not that
High SM = much more of a gap/spread 3.5 in natural, but ask them to be
extroverts goes up to 5, look like an extrovert. They can actually present
themselves as extroverts but particularly true if they were high in SM

All were introverts
Film Example
Amy Cuddy Ted Talk
Do our nonverbal govern how we think and feel about ourselves? It seems to
go both ways. Pretend to be powerful and you’ll be more likely to feel
powerful. Testosterone and cortisol levels differ between assertive/affective
leaders, how you react to stress, higher to T and low to cortisol.
High power condition, you will gamble, compared to baseline, 20% increase
in testosterone, 25% decrease of cortisone; low power condition, won't
gamble, 20% decrease in testosterone
Evidence for Amy Cuddy Perspective
Describe 2010 study:
26 females, 16 m’s
Cover story: “science of physio recordings”
Random assignment to low vs hi power pose;
Held 2 poses for 1 minute each;
Saliva samples before and 17 min later
Testosterone & cortisol assays
Self-report of feelings of power;
The Poses
High power condition: legs on the table, arms extended (like after winning a
race), standing up with fists on the table, expansion postures
Low power condition: arms wrapped around each other, legs crossed, very
inwards postures
The Results:
Gambling Risk?
Hi: 87%
Lo: 60%
Feelings of Power?
Hi = 2.57
Lo = 183
Hi = high-power poses versus Lo = low-power poses
Hi condition were more likely to gamble compared to the Lo condition
Hi condition had lower levels of cortisol
My Response?
Robustness and replicability?
Would like to see it replicated, meta-analyzed,
Dangers of “false” self-presentation?
Emotional leakage?
Many channels of communication, we can control our face, other
channels, our body and tone of voice. When someone is lying, if
you look at their body, you’re more likely to detect lying (or
listen to their tone) there might be leakage, something in their
