先前的研究表明，动作表征在对象加工过程中被激活，即使是在与任务无关的情况下。此外，有证据表明，词汇语义上下文可能会影响这种激活过程中的对象处理。最后，我们实验室和其他人的先前工作表明，基于功能（“使用”）和基于结构（“移动”）的动作亚型可能在激活特征上有所不同。然而，大多数评估这种影响的研究都需要手动对象相关的运动反应，从而必然影响动作表征的激活。本工作利用眼动跟踪和视觉世界范式任务，没有对象相关的行动，以评估激活的动作表征的时间过程，以及他们的词汇语义上下文的响应。在两个实验中，参与者听到一个目标词，并从一组四个物体中选择其所指。注视非目标物体的信号激活的功能之间共享的目标和非目标。实验评估激活的结构为基础的（实验1）或功能为基础的（实验2）干扰，使用中性的句子（“S/他看到了...”）或句子与相关的动作动词（实验1：“S/他拿起......";实验2：“S/他使用......”）。在这两个实验中，我们都观察到了与任务无关的动作信息激活。在中性语境中，基于结构的激活比基于功能的激活上升得更快，但更短暂。此外，在两个实验中，动作动词上下文可靠地修改激活模式。这些数据提供了关于在中性和动作相关的上下文中基于功能和基于结构的动作的激活动态的细粒度信息，以支持对象和动作处理的“双动作系统”模型（例如，）。
Previous studies suggest that action representations are activated during object processing, even when task-irrelevant. In addition, there is evidence that lexical-semantic context may affect such activation during object processing. Finally, prior work from our laboratory and others indicates that function-based (“use”) and structure-based (“move”) action subtypes may differ in their activation characteristics. Most studies assessing such effects, however, have required manual object-relevant motor responses, thereby plausibly influencing the activation of action representations. The present work utilizes eyetracking and a Visual World Paradigm task without object-relevant actions to assess the time course of activation of action representations, as well as their responsiveness to lexical-semantic context. In two experiments, participants heard a target word and selected its referent from an array of four objects. Gaze fixations on non-target objects signal activation of features shared between targets and non-targets. The experiments assessed activation of structure-based (Experiment 1) or function-based (Experiment 2) distractors, using neutral sentences (“S/he saw the …”) or sentences with a relevant action verb (Experiment 1: “S/he picked up the……”; Experiment 2: “S/he used the….”). We observed task-irrelevant activations of action information in both experiments. In neutral contexts, structure-based activation was relatively faster-rising but more transient than function-based activation. Additionally, action verb contexts reliably modified patterns of activation in both Experiments. These data provide fine-grained information about the dynamics of activation of function-based and structure-based actions in neutral and action-relevant contexts, in support of the “Two Action System” model of object and action processing (e.g.,).
