If you're
feeling helpless, it's best to be alone
Newswise — If you're
going to experience a period of
helplessness, it's best to be alone. New
research at the University of Haifa found
that laboratory rats that were on their own
when exposed to uncontrollable conditions,
which create a feeling of helplessness,
learned to avoid situations which create
such feelings better than rats that were
exposed to uncontrollable conditions in
pairs.
The way laboratory rats
react to uncontrollable situations in which
their behaviors have no influence on
subsequent events has been researched in the
past.
Results show that rats
that are exposed to a situation in which
they are powerless, for example, electric
shocks that they can't possibly avoid, have
a more difficult time learning how to avoid
them in the future than rats that were never
exposed to situations of helplessness – a
phenomenon known as "learned helplessness".
Researchers
choose to experiment with rats because they
are know as social animals and their brains
work much the same way as human brains.
However, most of the research done until now
was done on rats exposed to uncontrollable
conditions when they are alone.
In his doctoral
dissertation, Dr. Qutaiba Agbaria, under the
supervision of Dr. Richard Shuster, examined
the differences in learned helplessness
among rats that were exposed to
uncontrollable conditions alone and in
pairs.
The researcher began
with the hypothesis that rats would learn to
be more adaptable in social situations, or
in pairs, however, the research results
revealed a very different picture.
Rats that were exposed
to uncontrollable conditions in pairs coped
less well when they were no longer in
uncontrollable situations than rats that
were exposed to these situations alone.
The next phase of the
research examined the influence of a rat
that had never been exposed to an
uncontrollable situation on a rat that had.
These pairs of
rats showed greater adaptability than pairs
that had been exposed to helplessness as
individuals or in pairs.
In addition, the
researchers did not find outstanding
differences between the learning ability of
these pairs of rats – where one had been
exposed to uncontrollable conditions and the
other hadn't – and pairs that were never
exposed to uncontrollable conditions, which
means that the effect of "learned
helplessness" is effectively erased.
"Now that we have see
that "learned helplessness" can be
"unlearned", we should continue to examine
whether this change is a result of exposure
to a rat that was not exposed to
helplessness or rather that the social
behavior between the two animals has another
meaning," said Dr. Agbaria.
