Subclaims¶

q3 i3 Consistently high complexity had a strong effect on GCL in Round 1 (η2 = 0.19) and a small effect in Round 2 (η2 = 0.05). → Ines Zeitlhofer 2024 q3 i0 GCL did not differ between groups at post-test (η2 = 0.00). → Ines Zeitlhofer 2024 (2)

Evidence¶

Ines Zeitlhofer, Joerg Zumbach, Judith Schweppe. (2024). Complexity affects performance, cognitive load, and awareness. Learning and Instruction 94 (2024) 102001. https://doi.org/10.1016/j.learninstruc.2024.102001

q3 · i3 · causal · r1

Univariate analyses in the N = 98 experiment, with GCL measured by the Naïve Rating Questionnaire, showed "a strong effect of task complexity on GCL in Round 1" with printed effect size η2 = 0.19, and a small effect in Round 2 with η2 = 0.05.

"Addressing the impact of task complexity on GCL univariate analysis revealed a strong effect of task complexity on GCL in Round 1 (F (1,84) = 19.14, p < .001, η2 = 0.19) and a small positive effect in Round 2 (F (1,84) = 4.12, p < .05, η2 = 0.05)."

q3 · i0 · causal · r2

At the delayed post-test the GCL difference between the consistently high and gradually increasing groups was not significant, with printed η2 = 0.00.

"However, in the post-test, the difference between groups was not significant (F (1,84) = 0.11, p > .95, η2 = 0.00)."

Discussion¶

Related Claims¶

• Consistently high task complexity yields faster immediate problem-solving than gradually increasing complexity, with no post-test difference — related
• Constantly high complexity lowers reported intrinsic cognitive load and metacognitive strategy use compared with gradually increasing complexity — related
• Consistently high complexity raises meta-awareness in Round 1 but not in later rounds — related
