Recent studies have demonstrated that positive
and negative affective reactivity can be predicted by resting
electroencephalographic (EEG) asymmetry in frontal brain
regions. These studies used different methods to assess
asymmetry and affectivity. The goal of the present study
was a conceptual replication of these results and to investigate
their independence of employed procedures. Resting EEG
of 37 subjects was recorded and affective slides were presented
to obtain ratings of subjects' emotional reactions.
Different procedures were applied to the data to assess
the relation between asymmetries and affective reactivity.
Depending on the particular analysis procedure, there were
associations between anterior asymmetry and affectivity
in line with the published findings, opponent to those
findings, or no relation between anterior asymmetry and
affective reactivity.
