人类心智可以被划分为不同的（但相互作用的）功能模块，这一观点是许多认知理论的重要前提。虽然以前对模块化的研究主要研究输入域（例如，视觉）或中央处理，本研究侧重于输出域的认知表征。具体来说，我们询问输出域表示被封装到什么程度（即，免疫其他领域的影响，代表模块化的一个关键特征），通过研究同时行动需求（视觉和声音反应）之间的干扰决定因素。为了检查封装的程度，我们比较了由单一刺激触发的单响应与双响应性能。实验1解决的作用，刺激方式下的尺寸重叠的反应要求（刺激和反应的空间和兼容的整个）。在实验2中，我们操纵的反应之间的维度重叠的存在。大量的性能成本与双响应（与单响应）的需求，观察响应模式，条件和实验。与跨响应的共享空间代码相结合的维度重叠使得响应代码启动（即，输出域之间的有益串扰）。总的来说，结果是在与输出系统表示的强封装的想法不一致，并显示处理内容如何决定认知输出域之间的相互依赖程度。(C)2014 Elsevier Inc.

The idea that the human mind can be divided into distinct (but interacting) functional modules is an important presupposition in many theories of cognition. While previous research on modularity predominantly studied input domains (e.g., vision) or central processes, the present study focused on cognitive representations of output domains. Specifically, we asked to what extent output domain representations are encapsulated (i.e., immune to influence from other domains, representing a key feature of modularity) by studying determinants of interference between simultaneous action demands (oculomotor and vocal responses). To examine the degree of encapsulation, we compared single-vs. dual-response performance triggered by single stimuli. Experiment 1 addressed the role of stimulus modality under dimensionally overlapping response requirements (stimuli and responses were spatial and compatible throughout). In Experiment 2, we manipulated the presence of dimensional overlap across responses. Substantial performance costs associated with dual-response (vs. single-response) demands were observed across response modalities, conditions, and experiments. Dimensional overlap combined with shared spatial codes across responses enabled response-code priming (i.e., beneficial crosstalk between output domains). Overall, the results are at odds with the idea of strong encapsulation of output system representations and show how processing content determines the extent of interdependency between output domains in cognition.
