One of the most exciting moments in a prenatal ultrasound session is learning the sex of the baby.Following a conversation analysis perspective, we present a multimodal analysis of sequences of interaction between patient and practitioner at the time the foetus’ sex is the focus of attention. Based on video data collected from maternity wards and private practitioners, we report on two types of sequences, which illustrate the different ways of responding to the perceptually-occasioned formulation of the foetus’ sex: as a telling or as a noticing (in which case participants orient towards jointly seeing). While the possibility of both response is inherent to the sequential properties of noticing-based claims in general, we will discuss how the production of both types of sequences is sensitive and articulated to the distribution of epistemic authority as a practical achievement in this medical setting, along two dimensions: expert versus ordinary knowledge, and professional vision versus lay gaze.

'我知道它是什么'。产前超声检查中性别发现的交互研究

产前超声检查中最激动人心的时刻之一是了解婴儿的性别。按照对话分析的角度，我们对胎儿性别成为关注焦点时患者和医生之间的互动序列进行多模态分析。根据从产科病房和私人医生收集的视频数据，我们报告了两种类型的序列，它们说明了对胎儿性别的感知偶然表述的不同反应方式：作为讲述或作为注意（在这种情况下）参与者倾向于共同观看）。虽然这两种反应的可能性是基于注意的主张的序列属性所固有的，但我们将讨论这两种类型的序列的产生如何敏感并与认知权威的分布相联系，作为这种医学环境中的实际成就，沿着两个维度：专家与普通知识，专业视野与外行目光。
