Overall expressivity

Overall expressivity is a measure of facial expressivity regardless of emotional state. All action unit values are combined to determine the overall expressivity of the face, typically useful for measurement of blunted affect or disruption of facial expression as a consequence of motor retardation.

Raw Variables

Variable	Description
fac_comintsoft	Overall expressivity ‘soft’, equivalent to the average of all fac_EMOintsoft variables.
fac_cominthard	Overall expressivity ‘hard’, equivalent to the average of all fac_cominthard variables.
fac_comlowintsoft	Overall expressivity ‘soft’, for the lower half of the face.
fac_comlowinthard	Overall expressivity 'hard', for the lower half of the face.
fac_comuppintsoft	Overall expressivity ‘soft’, for the upper half of the face.
fac_comuppinthard	Overall expressivity hard, for the upper half of the face.

Derived Variables

Variable	Description
fac_comintsoft_pct	Overall expressivity as measured through presence of emotions i.e. the number of frames when any given emotion was being detected.
fac_comintsoft_mean	Overall expressivity ‘soft’ mean, equal to the average of all fac_comintsoft values.
fac_comintsoft_std	Overall expressivity ‘soft’ standard deviation, i.e. the standard deviation of fac_comintsoft.
fac_cominthard_mean	Overall expressivity ‘hard’ mean, equal to the average of all fac_cominthard values.
fac_cominthard_std	Overall expressivity ‘hard’ standard deviation, i.e. the standard deviation of fac_comintsoft.
fac_comlowintsoft_pct	Percentage of frames where any given emotion was detected in the lower half of the face.
fac_comlowintsoft_mean	Overall expressivity ‘soft’ mean, for the lower half of the face.
fac_comlowintsoft_std	Overall expressivity ‘soft’ standard deviation, for the lower half of the face.
fac_comuppinthard_mean	Overall expressivity ‘hard’ mean, for the upper half of the face.
fac_comuppinthard_std	Overall expressivity ‘hard’ standard deviation, for the upper half of the face.
