Where does comprehension collide?

In the logic of ideas, the comprehension of a concept is the full set of attributes it contains, the marks that together make it what it is, as opposed to its extension, the things it applies to. Arnauld and Nicole's Logic, or, The art of thinking (1662) drew this contrast: the comprehension of "triangle" includes having three sides and three angles, while its extension is every triangle there is. The referent is the internal attribute-content of a concept, later also called its intension, and it has nothing to do with understanding a passage of text or a syntax for building lists beyond the shared root of "grasping together."[1]

Unit

Not applicable

Measured by

Analysed by listing the defining marks a concept contains and contrasting them against the objects in its extension

In reading research and education, comprehension is the process of constructing meaning from text: the reader integrates the words on the page with prior knowledge to build a coherent mental representation of what the passage is about. Kintsch's 1988 construction-integration model describes how readers first generate a loose network of propositions and candidate meanings and then let activation settle so that context-appropriate meanings survive and a connected situation model forms. The referent is an understanding built in a reader's mind, measured by what they can recall, infer, and apply, and it is a different construct from the attribute-content of a concept in logic or a list-building notation in programming.[2]

Unit

The depth and coherence of the mental model a reader builds from a text

Recovery means

Not applicable

Measured by

Assessed through recall, question answering, inference tasks, and summaries that reveal how well the text was integrated
