Subclaims¶

q3 i? The hypothesized positive interaction between trait self-control and fluid reasoning was not statistically significant for mGPA (β = 0.03, p = 0.134), mathematics (p = 0.822), or physics (p = 0.460). → Schmidt FTC 2020

Schmidt FTC, Lindner C, Etzel JM and Retelsdorf J (2020) Self-Control Outdoes Fluid Reasoning in Explaining Vocational and Academic Performance—But Does It? Front. Psychol. 11:757. https://doi.org/10.3389/fpsyg.2020.00757

q3 · i? · associational · r3

Regression analysis with interaction terms probed via Johnson–Neyman; Table 2 prints TSC × Fluid Rea. estimates of 0.03, 0.00, and 0.01 with p-values 0.134, 0.822, and 0.460 — "no significant interaction effects" for any outcome.

"For all three indicators of achievement, no significant interaction effects (fluid reasoning × trait self-control) emerged."
