Affective Responses to Gay Men Using Facial Electromyography: Is There a Psychophysiological "Look" of Anti-Gay Bias.

Despite a wealth of attitudinal studies that elucidate the psychological correlates of anti-gay bias, studies that provide evidence of the physiological correlates of anti-gay bias remain relatively scarce. The present study addresses the under-representation of physiological research in the area of homonegativity by examining psychophysiological markers, namely the affective manifestations of anti-gay prejudice, and their correspondence with anti-gay behavior. Facial electromyography (EMG) was the technique used to acquire the psychophysiological markers via recordings from two facial muscle sites.
