Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Coherence revisions were significantly more frequent for Page writers (50%) than Scroll writers (31%). → Annie Piolat 1997 q3 i? Surface and cohesion improvements did not differ significantly between the two presentation conditions. → Annie Piolat 1997 (2)

Evidence¶

Annie Piolat 1997¶

Annie Piolat, Jean-Yves Roussey and Olivier Thunin. (1997). Effects of screen presentation on text reading and revising. International Journal of Human-Computer Studies. https://doi.org/10.1006/ijhc.1997.0145

q3 · i? · causal · r2

Experiment 2 error-correction results: the article reports the number of coherence revisions was significantly higher with Page than with Scroll. The discussion gives the rates as "Page writers (50%)" versus "Scroll writers (31%)".

"On the other hand, in line with Prediction 2, the number of coherence revisions was significantly higher with Page than with Scroll."

Annie Piolat 1997 (2)¶

q3 · i? · causal · r2

Experiment 2 null result for lower-level revisions: surface and cohesion improvements did not differ significantly between Page and Scroll conditions; almost all surface errors were corrected under both.

"Writers did not make significantly different surface or cohesion improvements under the Page and Scroll conditions."
