consequences of a mismatch are directed to a motor pro
gram that is monitored and updated by the prefrontal cortex (Gray, 1982, 1995). Ultimately, there
is an attempt
to establish a match within the comparator, which implies that anxiety is thereby reduced. While
this
response may occur quickly, there are no requirements for rapid goal achievement. Rather, the
comparator
strives to achieve a steady state of match between the next likely event in light of the actual
event.
