Prereasoning

Prereasoning refers to preparatory cognitive or computational activities that occur before formal reasoning or inference. It involves organizing information, framing a problem, and selecting strategies, with the aim of making subsequent reasoning more efficient. It is distinct from the act of drawing conclusions, though it shapes what conclusions are considered and how they are evaluated.

In cognitive psychology, prereasoning includes orienting attention to relevant features, constructing a problem representation, retrieving prior knowledge, setting goals, and defining the problem space. It also encompasses choosing heuristics or constraints that will guide later inference. Effective prereasoning can reduce cognitive load and search complexity, but biased representations can bias later conclusions.

In artificial intelligence and automated reasoning, prereasoning covers preprocessing tasks such as data normalization, feature extraction, domain modelling, and the initialization of inference rules or planning operators. It may include hypothesis generation or abduction that frames possible explanations before evaluation, and it can determine the tractability of the reasoning problem.

Examples across domains include mathematics, where problem restatement and listing givens precede solution steps; natural language understanding, where parsing and coreference resolution prepare the content for reasoning about meaning; and diagnostic reasoning, where symptoms and priors shape subsequent hypothesis testing.

Practically, prereasoning is linked to metacognition and problem formulation. It interacts with perception, memory, and knowledge retrieval. While beneficial for efficiency, excessive prereasoning can delay action, making a balanced approach desirable in real-world tasks.
