Abstract
The
research
examined
how
individuals
react
when
they
know
they are
missing
an
experimental
treatment
as a
function
of
assignment
to a
control
group
and
considered
whether
these
reactions
could
produce
treatment
effects.
There were
three
experimental
conditions.
Subjects
in
one
condition
were
informed
that they were a
control
group
and
unlike
the
experimental
group
would not
receive
extra
money
for
doing
well
on
experimental
tasks.
Subjects
in a
second
condition
were
informed
that they were in a
control
group
and
unlike
the
experimental
group
would not
receive
electric
shocks
for
poor
performance
on
experimental
tasks.
In the
third
condition
subjects
were
given
no
information
concerning
the
existence
of any
other
condition.
Dependent
measures
included
task
performance
and
measures
of
attitudes
toward
the
experiment.
Subjects
who
believed
they were
missing
a
positive
treatment
tended
to be
less
careful
,
make
more
errors
, and
do
less
work
than
subjects
unaware
of any
other
condition.
Subjects
who
believed
they were
missing
a
negative
treatment
tended
to be
more
careful
,
make
fewer
errors
, and
do
more
work
than
individuals
unaware
of any
other
condition.
Apparently
,
knowledge
of
missing
either
a
positive
or
negative
experimental
treatment
does
affect
behaviour.
There were
no
differences
in
attitude
towards
the
experiment
as a
function
of
experimental
condition.
These
significant
differences
in
task
performance
were
discussed
in
terms
of
various
social
psychological
theories
, the
evaluation
of
social
programs
, and
Campbell's
suggestion
of
"informed
randomization".
