q2 i? When interacting elements can be incorporated into a diagrammatic schema by modifying presentation mode, cognitive load is reduced and understanding is enhanced. → Marcus 1998

q2 · i? · causal · r?

The thesis's overall conclusion from its five experiments, stated in the abstract alongside its cognitive-load measures. It reports that incorporating interacting elements into a diagrammatic schema by modifying presentation mode reduces load and enhances understanding, per the quoted conclusion.

"However, if interacting elements can be incorporated into a diagrammatic schema by modifying the instructional presentation mode, cognitive load will be reduced and understanding enhanced."

Related Claims¶

• Cognitive Load Reduction Improves Learning — possibly the same claim (merge candidate)
• Split Attention Effect Degrades Learning — a narrower finding that bears on this claim
• Cognitive Overload Degrades Learning — a broader claim this one bears on
• Element interactivity and expertise reversal effects: cognitive load effects diminish and may reverse as expertise increases because known elements chunk into single elements — related
• Both cognitive offloading and the transient information effect reduce extraneous cognitive load by making information more accessible or less transient — related
• Understanding depends on the degree of interaction among elements of information — related
