Circumplex Model Of Affect

The Circumplex Model of Affect describes emotions in a two-dimensional circular space, containing arousal on the vertical axis and valence on the horizontal axis. The center of the circle represents a neutral valence and a medium level of arousal. The Circumplex Model of Affect in FaceReader is based on the model described by Russel (1980).

This option is only available for camera and video analyses. It displays a heatmap of the affect found in the analysis.

• Based on absolute percentage – The color of the heatmap is based on the percentage of time a certain affect was found in a video or camera analysis. The maximum is 100%.
• Based on maximum percentage – The color of the heatmap is based on the percentage of time the affect that was most present occurred. This percentage of time is set as the maximum and is colored red.

The Expression Intensity chart displays the following states: Neutral, Happy, Sad, Angry, Surprised, Scared, Disgusted, and Contempt.
