作为人类行为的观察者，婴儿面对的是一个复杂的动作流，其中停顿是罕见的，只是偶尔与有意动作之间的界限相吻合。两项研究调查了尽管存在这种复杂性，10至11个月大的婴儿（每项研究N = 16）是否具备沿着沿着与意图的启动和完成相关的边界解析正在进行的行为的技能。在熟悉了连续的日常动作的数字化序列之后，婴儿对测试版本表现出了新的兴趣，在测试版本中，动作在演员追求意图的过程中暂停（中断测试视频）。相比之下，在意图边界点暂停运动（完成测试视频）的停顿并没有引起婴儿的兴趣。此外，当意图被打断时，两种类型的测试视频之间的基本显著性差异并不是婴儿兴趣增加的来源（研究2）。这些研究结果表明，婴儿很容易检测到故意行动固有的结构的中断，因此解析正在进行的行为与这种结构。这种句法分析技巧可能是发展真正的意向性理解的先决条件。
As observers of human behavior, infants are faced with a complex flow of motion in which pauses are rare and only occasionally coincide with boundaries between intentional actions. Two studies investigated whether, despite such complexity, 10- to 11-month-old infants (N = 16 for each study) possess skills for parsing ongoing behavior along boundaries correlated with the initiation and completion of intentions. After being familiarized with digitized sequences of continuous everyday action, infants showed renewed interest in test versions in which motion paused in the midst of an actor's pursuit of intentions (interrupting test videos). In contrast, pauses that suspended motion at intention boundary points (completing test videos) sparked no such renewed interest on infants' part. Moreover, basic salience differences between the two types of test videos were not the source of infants' increased interest when intentions were interrupted (Study 2). These findings demonstrate that infants readily detect disruptions of the structure inherent in intentional action, and hence parse ongoing behavior with respect to such structure. Such parsing skill is likely a prerequisite to the development of genuine intentional understanding.
