It is well established that reading comprehension depends on a reader's awareness of how discourse is structured. Good readers are tuned to the ways that information is organized and to the signaling mechanisms that provide the cues to this organization. Good readers are able to identify the main or topic sentences as they appear in a text and are sensitive to text structures that help identify when and where to find main-idea sentences. Good readers recognize when new topics are introduced, how they are maintained through pronouns and other anaphoric cues, and when there is a topic shift, or when new themes or concepts are introduced. They are able to recognize the vocabulary that signals maintenance or shifts in discourse information as well as lexical forms that commonly identify specific organizational patterns in texts (e.g., cause–effect, comparison–contrast, problem–solution).

Discourse-structure awareness is often associated with a reading strategy or set of strategies (e.g., recognizing main ideas, inferring connections among parts of a text, recognizing organizational patterns in texts, identifying typical genre features of a text).
