The Limited Capacity Model separates attention from durable processing by tracing how finite resources are allocated across encoding, storage, and retrieval during mediated exposure
Premise
A message can win attention and still lose the information that matters. Annie Lang’s Limited Capacity Model of Mediated Message Processing treats mediated communication as a changing demand on finite cognitive resources. Structural features may automatically recruit attention at the same moment that new information, emotion, and complexity compete for the capacity needed to encode and store content.
That distinction changes design in safety, learning, health, and any setting where later retrieval matters. Engagement, completion, or vividness cannot stand in for the question the model asks: what information will still be available when the audience has to use it?

Theories & Explanatory Models
Explains how or why a communication process works by relating mechanisms, conditions or variables. Its value is an account that can guide inquiry into what produces an outcome, rather than a name for the outcome alone.
