“…(2) The motor recruitment hypothesis, in contrast, posits that facial effernce varies only as a function of emotional valence at weak levels of emo-. tional intensity, and that greater emotion-specific differentiation is achieved across the facial muscles at higher levels of emotional intensity (Cacioppo, Petty, & Marshall-Goodell, 1984;Cacioppo et aI., 1989). Geen (1989) recently provided data bearing on these hypotheses.…”

Surface electromyographic recordings in humans were first made less than 70 years ago, and the electromyographic study of covert facial actions during affect and emotion has less than a 20-year history. Despite the relative youth of facial electromyography, its use in combination with autonomic measures and comprehensive overt facial action coding systems has provided a sensitive and effective armamentarium for investigating emotion and affect-.laden information processing. Research over the past decade has demonstrated that facial electromyographic activity varies as a fil1lbion of the intensity, valence, and soc~ality of emotional stimuli and shows that facial electrOll,yographic activity is slightly different in deliberately manipulated and spontaneous expressions ofemotion. The multiply determined irature of facial actions and expressions, however, has limited the inferences that can be made about the psychological significance offacial eIectromyographic responses. These limita-"tions have begun to recede in recent years as a result ofadvances in the psychometric properties of facial electromyographic measurements, the quantification of electromyographic waveforms and patterns, the conjoint measurement offacial electromyographic and electrocortical activity, the conceptualization of psychophysiological relations, and the formalization ofpsychophysiological inference.

“…For example, we have completed several studies on perioral EMG activity and silent language processing (Cacioppo & Petty, 1979a;Cacioppo, Petty, & Marshall-Goodell, 1984;Cacioppo, Petty, & Morris, 1985). A fourth procedure that we have used to assess the extent and affectivity of information processing activity involves the use of psychophysiological measures.…”

“…10 More recently, both cognitive and affective states, which are not normally observable by inspec tion of facial expression when studied on video tapes, have shown detectable differences in EMG re sponses. 11 ' 14 Furthermore, Cacioppo 15 has reported in his study of affective state and EMG responses that lighting levels during experimentation should not be excessive.…”
