Science · Information Behavior Models

Assertion (A): Johnson's Model (1987) is structurally distinct from most other information-seeking models by virtue of its explicit incorporation of antecedent factors as determinants of information-seeking actions. Reason (R): Johnson's model explicitly identifies background factors (demographics and personal experience) and personal relevance factors (salience and beliefs) as antecedents that precede and shape both the selection of information channels and the resulting information-seeking actions, making pre-search contextual variables integral to the model's architecture.
