Kintsch thinks that comprehension is the result of a bottom-up process because the schema-as-filter theories cannot fully explain the comprehension process. The bottom-up process assigns a more decisive role to the comprehension process. This process shows that instead of only looking for the correct meaning, you will generate several meaning that could work and only later decide on the correct meaning.
He explains “construction” as the process of constructing several meanings of a word before deciding on the correct word. The meanings are then “integrated” into the sentence. The meanings that are constructed that work are then activated. The meanings that do not work are deactivated. Therefore, as you read, propositions are constructed. The propositions are then integrated into the context of the story. Propositions that work are activated while the others are deactivated.
