This document describes the full details of
the first data set (Study 1) used in Coutinho
et al., to appear. The Electroencephalography
(EEG) and facial Electromyography (EMG) signals
included in this dataset, and now made public,
were collected in the context of a previous study by
Peer, Grandjean, and Scherer, 2014 that addressed
three fundamental questions regarding the mechanisms
underlying the appraisal process: Whether
appraisal criteria are processed (a) in a fixed sequence,
(b) independent of each other, and (c) by
different neural structures or circuits. In that study,
an oddball paradigm with affective pictures was
used to experimentally manipulate novelty and intrinsic
pleasantness appraisals. EEG was recorded
during task performance, together with facial EMG,
to measure, respectively, cognitive processing and
efferent responses stemming from the appraisal
manipulations
