Summary of the results pertaining the classification of the EEG signals in terms of novelty and intrinsic pleasantness appraisal checks manipulation (Study 1).

Results are shown for different numbers of averaged trials (Av.) per participant, and different numbers of channels. The classifiers’ performance was quantified using the Unweighted Average Recall (UAR), and the difference between the UAR and the analytical chance level (diffUAR). Star symbols indicate significant one-tailed Student’s t -tests conducted to examine when classification performances were significantly above empirical chance level (***p p p Table 2.
