4 Meaning and Discourse Comprehension

How comprehension unfolds

Language comprehension builds an interpretation from spoken or written words. Readers and listeners combine linguistic information with grammar, context, memory, and knowledge of the world rather than simply adding word meanings together.

Comprehension is usually incremental: interpretations begin to form as language arrives, and later information can revise an earlier interpretation. Processes at the word, sentence, and discourse levels interact as this understanding develops.

From words to sentence meaning

Word recognition connects a written or spoken form with lexical knowledge: possible meanings, grammatical properties, and relations to other words. Because a word may have several senses, surrounding words can help select the intended one. For example, bank could refer to a financial institution or the side of a river, and context may not immediately eliminate the ambiguity.

Sentence comprehension combines word meanings according to grammatical structure. Syntax identifies relationships such as who acted and who was affected: The dog chased the cat describes a different event from the same words arranged in a different order.

A sentence can initially support more than one structural interpretation. In While Anna dressed the baby played, a reader might first group the baby with dressed, then revise that interpretation when played appears. This illustrates rapid interpretation and repair. Researchers differ on how strongly early parsing is guided by grammar alone rather than by multiple cues, including meaning and context; in practice, these sources of information interact.

Context and intended meaning

The same sentence can convey different meanings in different situations. If someone says It’s cold in here beside an open window, the utterance may function not only as a report but also as an indirect request to close the window. Comprehenders use the setting, preceding conversation, the speaker’s likely goals, and shared assumptions to infer intended meaning. This contextual interpretation is pragmatics.

Conversation also relies on common ground: information participants treat as shared. When someone says Put it beside the lamp, the conversation and visible surroundings can help a listener identify it and the lamp. Common ground can guide interpretation, but it does not guarantee that listeners consider only what the speaker knows; information available to the listener alone can sometimes interfere.

Connecting sentences into discourse

Understanding a passage requires linking sentences, not just interpreting each one separately. Cohesion refers to explicit linguistic links, such as pronouns, repeated words, and connectives. Coherence is the meaningful relationship readers or listeners construct among ideas, including relationships that are not stated outright.

In Maya dropped the glass. It shattered., the pronoun it refers back to the glass, creating cohesion. Readers can also infer that the glass shattered because it was dropped. This unstated cause-and-effect relationship is a bridging inference that helps make the passage coherent.

Other inferences may add plausible details, but comprehenders do not necessarily retain every possible inference. What they build depends on the text, context, knowledge, and current goals.

Mental models of discourse

A textbase represents the meanings and relations expressed in a text. A situation model represents the described events, people, objects, time, and place: the situation the reader or listener understands the text to be about.

For example, in A hiker reached the river. The bridge was washed out, so she waited for help, the textbase preserves the stated propositions and their connections. The situation model includes a hiker at a river, an unusable bridge, and a delay while she waits for assistance. A reader who forms this model can answer sensible questions about the scene even if the answers do not repeat the original wording.

Discourse models are built and updated as new information arrives. Readers connect new ideas to earlier ones, use relevant background knowledge, and maintain what matters for the current purpose. The construction–integration account describes comprehension as initially activating a range of word meanings, propositions, and possible connections, then integrating them into a coherent representation.

Putting the processes together

Comprehension proceeds from recognizing words and interpreting sentence structure to using context and connecting ideas across discourse. Grammar helps establish who did what; context helps resolve ambiguity and infer intended meaning; cohesion and inference help connect sentences. Mental representations preserve both what a text says and the situation it describes. Together, these processes let readers and listeners build, revise, and use a coherent understanding.
