The Research Library connects handbook observations to public evidence. Each record separates what the source reports from why it matters and how the handbook interprets it.
Canonical evidence objects
cognitive load
Public sources only. The records are intentionally concise so future chapters, topic search, and Knowledge CI/CD integrations can reuse the same model.

Attention Span
Gloria Mark draws on two decades of research into attention, distraction, and the effects of digital media on everyday work and life.
What the source reports
The work examines multitasking and interruptions in digitally mediated activity.
It frames attention as a limited resource affected by the conditions in which people work.
Why it matters here
Chapter 2 makes attention fragmentation visible as part of the hidden cost of repeatedly rebuilding understanding.
Guided Intelligence interpretation
The source does not endorse Guided Intelligence. It supports the chapter's emphasis on the cognitive cost of interruption and repeated reconstruction.
Sweller, van Merriënboer, and Paas review cognitive load theory and the limited capacity of working memory when people process information.
What the source reports
The article describes working memory as having limited capacity.
It reviews instructional approaches intended to reduce unnecessary cognitive load and support schema construction.
Why it matters here
Chapter 2 shows why repeatedly locating, interpreting, checking, and comparing information is a material cost rather than a neutral step.
Guided Intelligence interpretation
The source does not endorse Guided Intelligence. It supports the need to reduce avoidable reconstruction work rather than repeatedly impose it on individual workers.
