Subclaims¶

q3 i3 High-WMC readers identified correct and incorrect inferences better than low-WMC readers (η2 = .14). → Sanchez 2006 q3 i? No main effect of WMC on the number of correct causes in essays. → Sanchez 2006 (2)

q3 · i3 · causal · r2

Experiment 1 IVT: high-WMC readers (M = 15.28, SD = 2.42) outperformed low-WMC readers (M = 13.64, SD = 2.14); the ANOVA showed a "significant main effect of WMC" (η2 = .14).

"On this measure, a 2 /H11003 3 between-groups ANOVA identified a significant main effect of WMC [F(1,66) /H11005 10.75, MSe /H11005 4.50, p /H11021 .01; η2 /H11005 .14]."

Experiment 1 essay analysis: the 2x3 between-groups ANOVA on correct causes recalled found "no main effect of either WMC" or illustration condition; the article calls this lack of an overall WMC effect somewhat unexpected.

"The results indicated that there was no main effect of either WMC [ F(1,66) /H11005 1.44, MSe /H11005 1.39, p /H11022 .05; η2 /H11005 .02] or illustration condi- tion (F /H11021 1)."
