EEG correlates of mathematical and trait anxiety level
were studied in 52 healthy Russianspeakers during execution of
errorrecognition tasks with lexical, arithmetic and algebraic
conditions. Eventrelated spectral perturbations were used as a
measure of brain activity. The ERSP plots revealed alphabeta
desynchronizations within a 5003000 ms interval after task onset
and slowwave synchronization within an interval of 150350 ms.
Amplitudes of these intervals reflected the accuracy of error
recognition, and were differently associated with the three conditions.
The correlates of anxiety were found in theta (48 Hz) and beta2 (16
20 Hz) frequency bands. In theta band the effects of mathematical
anxiety were stronger expressed in lexical, than in arithmetic and
algebraic condition. The mathematical anxiety effects in theta band
were associated with differences between anterior and posterior
cortical areas, whereas the effects of trait anxiety were associated
with interhemispherical differences. In beta1 and beta2 bands effects
of trait and mathematical anxiety were directed oppositely. The trait
anxiety was associated with increase of amplitude of
desynchronization, whereas the mathematical anxiety was associated
with decrease of this amplitude. The effect of mathematical anxiety
in beta2 band was insignificant for lexical condition but was the
strongest in algebraic condition. EEG correlates of anxiety in theta
band could be interpreted as indexes of task emotionality, whereas
the reaction in beta2 band is related to tension of intellectual
resources.
