ANGER IMAGERY AND CORRUGATOR ELECTROMYOGRAPHY

Electromyography (EMG) of corrugator muscle activity has been positive ly related to negative affective states and psychopathology. Research exploring the relationship between corrugator EMG and personality trai ts is lacking. The relationship between corrugator EMG and state-trait anger was examined using affective imagery in 52 undergraduate female s divided into high and low trait anger groups. Results indicated that the high group reported greater difficulty with imagery, but reported more anger during the angry imagery as compared to the low anger grou p. Covarying imagery ability, no group differences in corrugator EMG w ere apparent. The greater experience of subjective anger by the high a nger group was not associated with greater corrugator EMG or better im agery ability.
