Statistical emotion control: Comparing intensity and duration of emotional reactions based on facial expressions

作者：

Highlights：

• Novel algorithm SEC for post-processing emotions obtained using facial expressions.

• Based on well-proven statistical process control to measure intensity and duration.

• Compares reactions across individuals using relative instead of absolute cutoffs.

• Validation using a real experiment with N = 560 timeseries of emotion scores.

• Differences in characterization between positive and negative emotional reactions.
