Is writing as difficult as it seems?

Experiment 1 assessed the time and effort allocated to writing subprocesses while generating written and verbal protocols over 10 weekly writing sessions. Within a 40-min session, planning time consumed about 45% in the first 5 min, but stabilized at near 30% thereafter. Generating text initially consumed 40% of the writers' time, peaked at 50% midway, and then declined to its original level. The time spent revising and reviewing was negligible early in writing sessions, but increased substantially late in the sessions. The highest and lowest quality documents could be differentiated on the basis of the amount of time the writers devoted to revising and to the magnitude of their RTs in a secondary interference task. Writers showed consistent, distinctive patterns of transitional probabilities between writing subprocesses both within and across sessions, yielding quantitative representations of their writing styles. In Experiment 2, writers overestimated the amount of time they devote to revising and overestimated the amount of effort they allocate to planning and text generation. Their estimations did not improve after 10 weeks of composing. A time-and-effort-based analysis of writing is proposed to account for these data.
