| summary | Recently, researchers have investigated the causal nature of attent
ional bias for threat (AB) in
the maintenance of anxiety disorders by experimentally manipulating it. They found that
training anxious individuals to attend to nonthreat stimuli reduces AB, which, in turn, reduces
anxiety. This effect supports the hypothes
is that AB can causally impact the maintenance of
anxiety. At a fundamental level, however, uncertainty still abounds regarding the nature of the
processes that mediate t
his effect. In this presentation
, we propose that
two contrasting
approaches may be de
rived from theoretical accounts of AB.
According to a first class of
models,
called the “valence
-
specific bias” models, modifying AB requires the modification of
valence
-
specific attentional
selectivity. According to a second class of models, called the
“attention control models”, modifying AB requires the modification of attention control,
driven by the recruitment of the dorsolateral prefrontal cortex. We formulate a series of
specific pred
ictions, to provide suggestions to trial these two approaches one against the
other.
This knowledge is critical for understanding the mechanisms of AB in anxiety disorders,
which bares important clinical implications. |
