Hello. I am Dr. Justin Yates,
Professor and Chair of the
Department of Psychological
Science at Northern
Kentucky University.
I will be discussing the
application of scales and
tasks in clinical
trials of impulsivity.

In this presentation,
I will first define
impulsivity and provide
a brief overview of psychiatric
conditions that are
characterized at least
in part by impulsivity.
I will then discuss
the measures of
impulsivity that
are commonly used.
These measures include both
self-report questionnaires
and cognitive behavioral tasks.

Impulsivity is a broad,
multifaceted construct
that encompasses
different behaviors.
As such, impulsivity can be
fractioned into
several categories.
Cognitive impulsivity is the
tendency to think or make
decisions without
careful consideration
or weighing of
potential consequences.
For example, a group of
teenagers may decide
to vandalize someone's
property as part of a prank.
For example, throwing eggs at
someone's house,
without thinking
about the consequences
of their actions.
Motor impulsivity is the tendency
to act without thinking.
An individual may blurt out
answers in a classroom,
or they may interrupt
ongoing conversations.
Emotion-based impulsivity,
as the name suggests,
involves impulsive
behaviors that
are triggered by strong
emotional responses.
To give a real-life example,
I attended the University of
Kentucky for graduate school.
The men's basketball team won
the national championship.
There was a group
of students burning
a couch one street over
from where I lived.
Risky choice is often lumped
with impulsivity and involves
decisions where outcomes are
uncertain or can be adversive.
Risky decisions are not
always maladaptive.
In fact, we commonly make
decisions that involve risk.
Deciding on which university
to attend involves some risk
as there is no guarantee that
the school one selects
will be the perfect fit.
Other risky choices
can be problematic.
For example, driving
while intoxicated is
a risky choice that can lead
to significant injury or death.
