70名右撇子受试者(35名男性和35名女性)被展示了消极、中性和积极的面部情绪表情的偏侧图片。对于每个情感类别，一半的照片是男性面孔，一半是女性面孔。在一半的试验中，图片被显示在左侧视觉半视野中，而在另一半试验中，图片被显示在右侧半视野中。问题是，刺激面孔的性别是否与受试者的性别相互作用，从而导致大脑半球对面部情绪感知的差异。测定了反应准确度和反应时间。这些照片是通过幻灯片放映机放映的，镜头上安装了高速快门，以便进行速显演示。结果表明，右脑在识别刺激面孔方面比左脑更准确、更快，而且总体上更容易识别积极的情绪。刺激的性别和受试者的性别之间缺乏显著的交互作用，这表明在侧向性研究中，这两个因素并不相互关联或混淆。
Seventy right-handed subjects (35 males and 35 females) were shown lateralized pictures of negative, neutral, and positive facial emotional expressions. For each emotional category, half of the pictures were of a male face showing the emotion, half were of a female face. The pictures were shown in the left visual half-field for half of the trials and in the right half-field for the other half of the trials. The question addressed was whether the sex of the stimulus face interacts with the sex of the subject for hemisphere differences in perception of facial emotions. Response accuracy and reaction time were measured. The pictures were shown from a slide projector with a high-speed shutter mounted to the lens to allow for tachistoscopic presentations. The results showed that the right hemisphere was more accurate and faster than the left in recognizing the stimulus faces, and that positive emotions were overall more easily recognized. The lack of a significant interaction between sex of the stimulus and sex of the subject indicates that these two factors are not interrelated or confounded in laterality research.
