Description

When using subjective rating scales to measure cognitive load, researchers should not assume that the average of ratings given after each task equals a single rating given after the whole learning phase. Across two experiments, "the delayed ratings of both effort and difficulty were significantly higher than the average of the six ratings made during problem solving", while affective ratings showed no such difference. The choice of measurement point therefore changes what the rating indicates and should be reported and justified.

Accounts

• Treat immediate (per-task) and delayed (post-sequence) subjective cognitive load ratings as distinct, non-interchangeable measures: When using subjective rating scales to measure cognitive load, researchers should not assume that the average of ratings given after each task equals a single rating given after the whole learning phase. Across two experiments, "the delayed ratings of both effort and difficulty were significantly higher than the average of the six ratings made during problem solving", while affective ratings showed no such difference. The choice of measurement point therefore changes what the rating indicates and should be reported and justified. (Schmeck et al. (2015))

Claims

• A single delayed cognitive load rating after a problem sequence is significantly higher than the average of immediate ratings for both mental effort and perceived difficulty (Experiment 1) [+M]
• The delayed-higher-than-immediate difference for cognitive load ratings replicates regardless of whether problem complexity increases or decreases across the sequence (Experiment 2) [+M]
• Delayed ratings of affective variables (interest and motivation) do not differ from the average of immediate ratings, unlike cognitive load ratings [+M]
• Delayed cognitive load ratings appear to be based more on the more complex problems in the series than on a recency effect [+W]
