This study examines the proposal that the syntax-discourse interface is particularly vulnerable, and therefore components of this interface are acquired later than those of the syntax-semantics interface. The proposal is examined using data from the native language acquisition of markers of point of view in American Sign Language and Brazilian Sign Language, known as constructed action (CA). CA was observed in the spontaneous production of two case studies from as early as 1 year, 7 months of age, with the correct eye-gaze, facial expression, and manner of movement. However, the children sometimes failed to indicate the referent whose point of view was being expressed, and were not skilled at maintaining point of view marking across discourse. The results are interpreted as providing support for the vulnerability of the syntax-discourse interface, and for the interpretation of this vulnerability in connection with children's relatively poor ability to assume an identical discourse context with their interlocutor.
句法-语篇接口特别容易出错，因此该接口的组成部分比句法-语义接口的组成部分习得时间更晚。我们使用来自美国手语和巴西手语中视角标记的母语习得数据来检验这一观点，这些视角标记被称为构建动作（CA）。早在1岁7个月大时，在两个案例研究的自发表达中就观察到了构建动作，伴有正确的眼神、面部表情和动作方式。然而，孩子们有时未能指明正在表达其视角的指称对象，并且不擅长在整个语篇中保持视角标记。研究结果被解释为支持了句法-语篇接口的易出错性，以及支持了将这种易出错性与儿童相对较差的与对话者假定相同语篇语境的能力联系起来的解释。
