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. Whether heterosexual men's implicit affective reactions to gay male couples best predicted their overt and covert discriminatory behavior toward a presumed gay male confederate was determined. The strength of the implicit affective reactions to predict anti-gay discrimination was then tested against the strength of participants' implicit cognitive reactions acquired via the Implicit Association Test (IAT). Results indicated that the affective reactions recorded via facial EMG emerged as the strongest predictor of discrimination toward gay men compared to the cognitive reactions recorded using the IAT. Findings support the contention that emotional reactions to gay men using implicit techniques such as facial EMG are potentially valuable pathways toward understanding the nature and sequelae of anti-gay behavior.
尽管有大量的态度研究阐明了同性恋偏见的心理相关性，但提供同性恋偏见的生理相关性证据的研究仍然相对较少。本研究通过检查心理生理标志物，即同性恋偏见的情感表现，以及它们与同性恋行为的对应关系，解决了同情感研究在该领域代表性不足的问题。面部肌电图（EMG）是通过从两个面部肌肉部位记录来获取心理生理标志物的技术。确定了异性恋男性对男同性恋夫妇的内隐情感反应是否最能预测他们对假定的男同性恋同伙的公开和隐蔽的歧视行为。然后，通过内隐联想测验（IAT）获得的参与者的内隐认知反应的强度来测试内隐情感反应预测反同性恋歧视的强度。结果表明，与使用 IAT 记录的认知反应相比，通过面部 EMG 记录的情感反应是预测对男同性恋者歧视的最强预测因子。研究结果支持这样一种观点，即使用面部 EMG 等内隐技术对男同性恋者的情绪反应可能是理解反同性恋行为的本质和后果的有价值途径。
