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 i3 In a two-group between-subjects experiment, the KBD condition rated the robot significantly higher on perceived responsible behavior than the control condition (d = 0.930). → Stephan Vonschallen 2026

q3 · i3 · causal · r2
Welch two-sample t-test in the preregistered two-group between-subjects experiment (KBD n = 12, control n = 12) comparing the 9-item Perceived Responsible Behavior scale. The KBD group scored "significantly higher perceived alignment with responsible robot behavior than the control group", d = 0.930, p = .034.
"The KBD group (M= 5.49,SD= 1.23) reported significantly higher perceived alignment with responsible robot behavior than the control group (M= 4.47,SD= 0.95),t(20.65) = 2.277,p = .034,CI= [0.087, 1.950],d= 0.930."
Discussion¶
Related Claims¶
- Qualitative transcript analysis showed the KBD robot used Socratic questioning, slide-grounded sourced claims, and explained feedback far more often, while the control robot produced false statements and never cited sources — related
- KBD configuration produced no significant between-condition differences in system acceptance, intrinsic motivation, or subjective learning effectiveness in a single tutoring session — related
- An exploratory path model suggests perceived responsible behavior mediates the association between KBD and both learner motivation and acceptance — related
- Objective learning gains did not differ significantly by condition in the primary ANCOVA, but KBD showed a significant positive effect on learning gains in exploratory regressions accounting for learner covariates — related
