Subclaims¶

q3 i2 Explicit aim was significantly larger in the Japanese group than in the Norwegian group in both early and late adaptation periods (ηp² = 0.11). → Yamada 2025

Evidence¶

Yamada, C., Itaguchi, Y., & Rodríguez-Aranda, C. (2025). Unconscious cultural cognitive biases in explicit processes of visuomotor adaptation. npj Science of Learning. https://doi.org/10.1038/s41539-025-00335-0

q3 · i2 · causal · r1

A two-way mixed ANOVA on explicit aim (verbal reports converted to degrees) in a visuomotor adaptation experiment with 24 Norwegian and 24 Japanese students found a significant cultural group effect, "ηp 2 =0 . 1 1" (ηp² = 0.11), with larger Japanese means (early M = −13.93°) than Norwegian (early M = −6.42°).

"It showed signi ficant cultural group effects in both early (the initial 20 trials) and late (the last 20 trials) periods of the adaptation block (F(1,46) = 5.66,p < 0.05, ηp 2 =0 . 1 1 ) ."

Related Claims¶

• Implicit motor learning measures do not differ between Norwegian and Japanese groups — related
• Japanese participants change their aiming direction more frequently than Norwegian participants, regardless of previous hit or miss — related
• Japanese participants change aiming direction frequently even after successfully hitting the target — related
• No correlation between the degree of target error and degree of aim change in either group — related
• Multi-state model parameters do not differ between Norwegian and Japanese groups — related
• Implicit learning measures from verbal reports do not correlate with aftereffects or slow-process learning rates — related
