Abstract Research has repeatedly shown that problems arise when students are asked to link information co-textually and contextually across larger phases of discourse. Within Systemic Functional Linguistics (SFL), a text-oriented theory of language, co-textual and contextual links are analyzed and operationalized in terms of textual and logical metafunctions, both of which work together to connect and enable experiential and interpersonal metafunctions. While most writing studies to date have investigated text as product (synoptic approach), there has been increasing interest in studying text as an evolving process (dynamic approach). The current study contributes to this emerging research by examining the real-time choices made by six student writers. Drawing on keystroke logging software (Inputlog), it explores writers’ revision choices within the systems of theme , information , and identification , in conjunction with the logical metafunction. Results indicate that complex choices contribute to unfolding cohesiveness and information flow, where choices in specificity and congruency are key contributors to managing texture while also manipulating complexity and context-dependency. Overall findings suggest that students may benefit from an explicit focus on the nominal group as a means to create and maintain texture and cohesion through over-specification, classification (pre-modifiers), and qualification (post-modifiers).

在学术写作中操纵质地和内聚力：击键记录研究

摘要 研究一再表明，当学生被要求在更大的话语阶段以共同文本和上下文的方式链接信息时，就会出现问题。在系统功能语言学 (SFL) 中，基于文本和逻辑元功能分析并操作了面向文本的语言理论、共文本和上下文链接，这两者一起工作以连接并实现体验和人际元功能。虽然迄今为止大多数写作研究都将文本作为产品（概要方法）进行研究，但人们对将文本作为一个不断发展的过程（动态方法）进行研究的兴趣越来越大。目前的研究通过检查六名学生作家所做的实时选择，为这项新兴研究做出了贡献。借鉴击键记录软件（Inputlog），它结合逻辑元功能探讨了作者在主题、信息和识别系统中的修订选择。结果表明，复杂的选择有助于展开凝聚力和信息流，其中特异性和一致性的选择是管理纹理的关键因素，同时也操纵复杂性和上下文依赖性。总体研究结果表明，学生可能会受益于明确关注名义群体，作为通过过度规范、分类（前修饰符）和资格（后修饰符）来创建和保持结构和凝聚力的一种手段。其中特异性和一致性的选择是管理纹理的关键因素，同时也操纵复杂性和上下文相关性。总体研究结果表明，学生可能会受益于明确关注名义群体，作为通过过度规范、分类（前修饰符）和资格（后修饰符）来创建和保持结构和凝聚力的一种手段。其中特异性和一致性的选择是管理纹理的关键因素，同时也操纵复杂性和上下文相关性。总体研究结果表明，学生可能会受益于明确关注名义群体，作为通过过度规范、分类（前修饰符）和资格（后修饰符）来创建和保持结构和凝聚力的一种手段。
