Methodoly
A) The poll opinion questionnaire (Table
I) asked volunteers:
1) to declare their intended vote v and if they could change their
mind (v’) until the Election Day;
2) to evaluate (e(ai)) a selection of 6 advertisements ai
of the Yes and No Radio/TV propaganda; and
3) to declare if ai would influence (i(ai)) their voting.
The poll took place during the week preceding the election and involved
1136 people, 32 of whom (EEG group) had their EEG registered while answering
the poll.
Factor and regression analysis were used to study data about v,
e(ai) and i(ai).
B) The correlation Ri,j between the EEG activity recorded at the
recording sites ri,rj was calculated for all the 20 electrodes
of the 10/20 system and for the EEG epochs associated to:
1) voting (V),
2) advertisement evaluations (E) and
3) influence assessment (I).
