The document describes a scientific study that investigated whether casual video games could improve mood and decrease stress. 134 participants played casual games like Bejeweled 2 or Peggle for 20 minutes while connected to EEG and HRV equipment to measure brain waves and physiological responses. Results found that the game groups had significantly greater reductions in negative mood and stress levels compared to a control group based on psychological surveys and brain wave analysis. This provides evidence that casual video games may have therapeutic benefits for relieving stress and improving mood.

is
a
factor
analytically
derived
inventory
that
measures
six
subscales:
tension,
depression,
anger,

it
calculates
a
“Total

16. Depression
— Depression
is
a
serious
medical
illness;
it’s
not
something
that
you
have
made
up
in
your
head.
It’s
more
than
just
feeling
"down
in
the
dumps"
or
"blue"
for
a
few
days.
It’s
feeling
"down"
and
"low"
and
"hopeless"
for
weeks
at
a
time.
(National
Institute
of
Mental
Health,
2010)

17. Par(cipants
— Participants
were
Adults
(=>18)
that
signed
an
Institutional
Review
Board
approved
informed
consent
agreeing
to
participate
and
met
the
criteria
score
for
inclusion
(PHQ9
score=>5).

18. Par(cipants
Qualifying
participants
then
completed
the
POMS,
State/Trait
Anxiety
Inventory,
psychological
assessments,
demographic
profile
sheet,
and
the
remaining
components
of
the
Patient
Health
Questionnaire
(PHQ).
The
participants
also
gave
a
small
saliva
sample
for
biochemical
testing.
At
this
point
participants
opened
an
envelope
containing
a
random
assignment
to
the
control
or
experimental
groups.

19. Experimental
Group
If
the
participant
was
assigned
to
the
experimental
group
they
were
given
a
choice
of
three
popular
casual
video
games
to
play.
Research
has
demonstrated
that
freedom
to
choose
is
an
important
precursor
to
experiencing
the
full
benefits
of
recreation
participation.
The
participant
then
played
the
games
of
their
choice
for
30
minutes
while
being
recorded.

20. Experimental
Group
— In
addition
to
the
two
lab
sessions
scheduled
one
month
apart,
the
experimental
group
was
instructed
to
play
the
casual
video
game
of
their
choice
at
home
for
at
least
30
minutes
3x
per
week
(At
least
24
hours
between
sessions)
for
one
month.
Participants
were
asked
to
keep
a
log
of
the
amount
of
time
spent
playing
the
game
during
the
month.
The
average
game
playing
time
for
the
experimental
group
was
minimum
30
max
68
minutes
and
the
mean
40.7
minutes.

21. Control
Group
— If
the
person
was
assigned
to
the
control
group
biosensors
were
placed
by
the
researcher
and
baseline
psychophysiological
data
was
recorded
for
6
minutes.
— The
control
participant
was
then
instructed
to
surf
the
National
Institutes
of
Mental
Health
consumer
web
site
on
depression
for
30
minutes
while
psychophysiology
data
was
being
recorded.
http://www.nimh.nih.gov/health/topics/
depressionindex.shtml

22. Methods
— All
sessions
were
conducted
in
a
room
with
minimal
distractions
(blank
walls,
no
outside
view,
minimal
noise).
The
researcher
administered
psychological
assessments
and
connected
the
participants
to
physiological
monitoring
equipment
following
the
same
procedure
for
both
groups.
All
participants
sat
in
the
same
chair
in
front
of
the
same
computer.

In
terms

the

experienced

and
this
was

except

27. Changes
in
POMS
Categories
— The
following
slides
depict
the
differences
between
the
video
game
group
and
the
six
categories
of
the
POMS.
In
general
there
were
Decreases
in:
—
Tension:
49.6%
— Anger:
55%
—
Depression:
50%
—
Fatigue:
58%
—
Confusion:
50%
—
and
a
33%
Increase
in
Vigor

28. Anxiety
— Anxiety
and
fear
are
two
different
emotions
but
are
commonly
regarded
as
the
same.
Fear
is
defined
by
an
obvious
source
of
danger.
However,
with
anxiety,
danger
is
not
typically
specified
clearly,
as
it
can
occur
in
situations
where
danger
is
not
observable
(Butcher,
et
al.,
2007).

29. Anxiety
Cont’d
— Anxiety
disorders
develop
when
anxiety
becomes
excessive
or
uncontrollable
— Common
symptoms
— Negative
mood
— Unnecessary
worry
— Chronic
stress
— Avoidance
of
specific
situation

30. Types
of
Anxiety
—
State
anxiety
refers
to
a
transitory
emotional
state
or
condition
that
can
be
characterized
by
subjective,
consciously
apparent
feelings
of
tension
and
apprehension,
and
an
amplified
autonomic
nervous
system.
— Trait
anxiety
refers
to
an
individual’s
proneness
for
anxiety
and
a
common
tendency
to
respond
with
anxiety
when
confronted
with
a
perceived
threat.

31. STAI
— To
determine
if
there
is
any
change
in
participants
anxiety
level
the
STAI
will
be
used
to
measure
changes
in
both
state
(S-­‐Anxiety)
and
trait
(T-­‐
Anxiety)
anxiety.
— The
STAI
is
a
brief,
self-­‐report
inventory
that
consists
of
20
S-­‐Anxiety
questions
and
20
T-­‐
Anxiety
questions,
for
a
total
of
40
anxiety
questions.

37. The
Effectiveness
of
Casual
Video
Games
in
Improving
Cognitive
Performance
in
People
Over
50:
A
Randomized
Controlled
Study

38. Why
is
it
important?
— Most
adults
experience
a
decline
in
cognitive
functioning
— When
this
loss
begins
and
its
intensity
varies
considerably
— Cognitive
decline
can
also
impact:
— Episodic
memory
(recall
info
in
linked
format)
— Perceptual
reasoning
(identifying
objects)
— Inductive
reasoning
(using
logic
for
decisions)

39. Speed
of
CogniDve
Processing
— Area
of
cognition
receiving
most
of
attention
due
to
its
broad
influence
over
various
factors
— Important
to
specific
operations:
— Episodic
memory
— Working
memory
— Reasoning
abilities
— Verbal
fluency
— Also
linked
to:
— New
learning
— Everyday
task
performance

40. Trail
Making
Test
— The
TMT
is
a
standardized
set
of
five
visual
search
and
sequencing
tasks
that
are
heavily
influenced
by
attention,
concentration,
resistance
to
distraction,
and
cognitive
flexibility
(or
set-­‐shifting).
—
It
is
highly
useful
in
the
evaluation
and
diagnosis
of
brain
injury;
frontal
lobe
deficits;
problems
with
psychomotor
speed,
visual
search
and
sequencing,
and
attention;
and
impairments
in
set-­‐shifting.

were
tracked.
Those
parDcipants
that

Bejeweled

for

showed
an

These
