Homosexuals are believed to have a "sixth sense" for recognizing each other, an ability referred to as gaydar. We considered that being a homosexual might rely on systematic practice of processing relatively specific, local perceptual features, which might lead to a corresponding chronic bias of attentional control. This was tested by comparing male and female homosexuals and heterosexuals - brought up in the same country and culture and matched in terms of race, intelligence, sex, mood, age, personality, religious background, educational style, and socio-economic situation - in their efficiency to process global and local features of hierarchically-constructed visual stimuli. Both homosexuals and heterosexuals showed better performance on global features - the standard global precedence effect. However, this effect was significantly reduced in homosexuals, suggesting a relative preference for detail. Findings are taken to demonstrate chronic, generalized biases in attentional control parameters that reflect the selective reward provided by the respective sexual orientation.
人们认为同性恋者有一种识别彼此的“第六感”，这种能力被称为同性恋直觉。我们认为，成为同性恋者可能依赖于对相对特定、局部感知特征进行处理的系统练习，这可能会导致注意力控制出现相应的长期偏差。通过比较在同一国家和文化中成长、在种族、智力、性别、情绪、年龄、个性、宗教背景、教育方式和社会经济状况方面相匹配的男性和女性同性恋者及异性恋者处理分层构建视觉刺激的全局和局部特征的效率，对此进行了测试。同性恋者和异性恋者在全局特征上都表现得更好——这是标准的全局优先效应。然而，这种效应在同性恋者中显著降低，表明他们相对更偏好细节。研究结果被用来证明注意力控制参数中存在长期的、普遍的偏差，这反映了各自性取向所提供的选择性奖励。
