Hi, I'm Michael Corayer and this is Psych Exam Review. In this video we're going to take a look
at the relationship between traits and behaviors. So I mentioned in the previous video that trait
assessments generally don't allow us to make predictions about specific behaviors and part of
the reason for this is that these assessments are designed to be used by many different people. And
so there's a bit of a trade-off between the level of detail and accuracy that we can get about each
individual and how applicable our assessment is to all people. You could imagine that I could
create a very specific assessment that's for a particular group of people, you know, so they all
have the same job, they have similar backgrounds, they're the same age, etc. And in that case my
assessment might allow me to make some more specific predictions about their behaviors,
but if I'm assessing something like the Big Five then that's gonna be very general. As a result,
I won't be able to make specific predictions about people's behavior based on that assessment. So we
might wonder about these assessments and think well, let's say somebody scores as being very
introverted, right? So we might wonder well, just because somebody scores as being very introverted,
what does that tell us about their actual behavior? Can we predict that they actually
spend more time alone? Or might that not be the case? So this brings us back to an idea that I
mentioned in the unit on intelligence and this is the idea that we have these three parts. We have
this sort of triangle and we have a construct and so this is sort of a hypothetical property that we
think exists, and it's going to be connected to particular behaviors, that's why we think
it exists. So in the case of intelligence that was; intelligence was the construct and
we thought well, there's things like grades in school that we see and those make us think that
there's differences in intelligence. And then we also design assessments like IQ tests and
then we look for relationships between these three parts. And so in the case of a personality trait,
we might have some construct which we say "okay, I think openness to experience is a,
you know, a trait that exists and it's going to be connected to particular behaviors like trying
new things or exposing yourself to new ideas." Alright, so I have this connection here between
this hypothetical property or trait and actual behavior, and then I have some assessment that
also is linked to the general hypothetical property here. I say okay I've designed an
assessment of openness to experience and then I might wonder well is there a clear
relationship between actual behaviors that I think demonstrate this and assessments that claim that
they're measuring this? So this is sort of the section we're wondering about here. Is there
a relationship between the behaviors and the assessment results? And this brings us to some
work by Walter Mischel and in 1968 he published a book called personality and assessment and he
looked at the relationship between traits and behaviors. And when looking at single
traits and specific behaviors, he found an average correlation of about 0.3 and many people thought
this was quite low. And they thought this, I mean, this means that we're not able to make very good
predictions about behavior based on a particular trait, and maybe we shouldn't bother measuring
traits at all. I mean, they're not really telling us much about actual real-world behavior. But
there's a few caveats that we should keep in mind when we think about this. This appears to be quite
a low correlation but we should remember that traits are about tendencies they're not about
specific behaviors. And so we shouldn't expect them to make predictions about specific behaviors
and, related to this, the idea that when we look at this correlation it's between single traits
and single behaviors but traits don't operate in isolation. They're all acting all the time.
So just because you're open to experience that doesn't mean that that's the only thing that's
shaping your behavior and so other traits might be influencing you and that's why we shouldn't
expect to see that, well, just because you're high in openness we should always see this one
particular behavior, right? That certainly isn't the case. It's not going to be deterministic like
that. Or if you score high on this trait then you always act this way. I mean, we would be
actually more surprised to see that be the case. So when we think that way we might realize, well,
maybe this correlation isn't so low. And then lastly we have the idea that the situation also
matters. There's a situational context and that's not being taken into consideration
here. So just because you are very extroverted doesn't mean that you're always going to be
around other people. You know, you might still want to be alone sometimes even if you're very,
very high in extraversion. And that's because there's certain situations where you might feel
the need to be alone regardless of how extroverted you are. And so now I mean that again it wouldn't
perfectly predict your behavior. Alright, so we should keep this in mind. It doesn't mean just
because we have a lower correlation here that assessing personality traits is useless. Ok,
so some other ways that we can look at this relationship between traits and behaviors. One
way is what's called "experience sampling" and so what we do here is we randomly buzz a participant.
Initially this was done with pagers but now it's done with smartphone apps, and the participant
simply records what they're doing or what they're thinking about at a certain time during the day.
They don't know it's going to suddenly buzz and say "hey what are you doing?" and what this does
is it means we can measure actual behaviors. "Oh, I'm reading this new book" or "I'm you know
chatting with my friends I'm in a cafe having a conversation with my friends about whatever".
And so we're measuring actual behaviors, right? People didn't know we were going to measure it,
they don't know when it's going to ask them, and we can then compare that to their actual
personality assessments. Ok, here's their actual behaviors, here's their scores on, say, a big five
assessment and then we can see how related are these things. So somebody scores high on openness,
how often do we see that they're trying new things or exposing themselves to new ideas, right? That
would tell us this relationship between the trait score and their actual behaviors. Ok, and before
we finish talking about traits I want to go to an overall criticism of trait-based assessment. And
this is not to say that it's not useful. But we should keep this in mind and this is that trait
based-assessment doesn't tell us how personality works, right? So it's not going to be sufficient
for really explaining personality differences. It helps us to describe how people differ, but it
doesn't tell us about intrapersonal functioning. So what intrapersonal functioning refers to is the
functioning within a person, within an individual. So how does a person process information? How do
they make decisions? How do they choose behaviors, right? Labeling traits doesn't actually explain
any of that, right? And in some ways we could criticize trait-based assessment as using a sort
of circular logic. So what do I mean by that? Well, the idea is we're sort of just labeling
things and then saying that those are, that label is the explanation for the things. So for example
we could say "okay we have Jill and Jill is very neat and organized." Ok, so well why is
it that Jill is very neat and organized? What's the explanation for this? And the answer that we
have with trait-based assessment is "well Jill is very neat and organized because she is high
in conscientiousness", right? And that seems to be a bit of an explanation. Ok, here's her behaviors,
why are these happening? "Well, she's high in conscientiousness". Then we ask "well why is
it that Jill is high in conscientiousness?" We say, "well because she's very neat and
organized. She has these behaviors", right? We say that's the explanation for why she's high in
conscientiousness, because she's very neat and organized. And she's very neat and organized
because she's high in conscientiousness. It's not really explaining what's causing her to be
very neat and organized, or what's causing her to be high in conscientiousness? So we might wonder,
is it something about her upbringing, something about her socio-cultural context?
Is it something about her biology that's causing this behavior and it's causing her
to be more conscientious than someone else, right? And so we're going to need to look
at some other perspectives on personality in order to try to address that. And that's what
we're going to do in some of the following videos. So I hope you found this helpful,
