q3 i? Age negatively predicted redundancy score in the Inefficient first condition. → Davis 2022

Evidence¶

Davis 2022¶

Davis, S., Rawlings, B., Clegg, J. M., Ikejimba, D., Watson-Jones, R. E., Whiten, A. & Legare, C. H. (2022). Cognitive flexibility supports the development of cumulative cultural learning in children. Scientific Reports. https://doi.org/10.1038/s41598-022-18231-7

q3 · i? · causal · r2

In the Inefficient first condition generalized mixed effects model, "younger children showed higher redundancy scores than older children" (beta = − 0.27, p = 0.001). Redundancy scores were highest in Phase 3 when the inefficient method was blocked.

"There was a significant negative effect of age (beta = − 0.27 p = 0.001, CI: − 0.48 to − 0.065); younger children showed higher redundancy scores than older children."

Discussion¶

Learner Variables¶

• Age and Developmental Stage — predictor: learners who differ on it differ in outcomes
