The photos show the typical facial expressions induced by the chop stick in the smile and no-smile conditions.
Figure 2.
Results of the EWL-60-S questionnaire; Data were collected on a separate sample, Facial Feedback group is coded by line color.
Items summarized according to the EWL-60-S-manual. Scores are based on difference post-experimental EWL-60-S minus pre-experimental EWL-60-S results; positive values indicate that people loaded higher on this scale after completion of the EEG experiment. Error bars indicate +/−1 SE.

Figure 3.
Response-locked ERPs on midline electrodes FZ and CZ for correct (thin lines) and erroneous (thick lines) responses.
Stick-positions are coded by line style.
Figure 4.
Spline-interpolated isovoltage maps depicting the mean amplitude in a time window 20 to 100 ms of the difference wave “error” minus “correct”.
Relative scaling is used with lighter shades representing more negative amplitudes.
