Subclaims¶

q3 i? Participants showed better choice accuracy in the observational learning condition than the individual learning condition (β = 0.12, t = 5.2, p < 0.001), with no age by condition interaction. → Rodriguez Buritica 2024

Rodriguez Buritica 2024¶

Rodriguez Buritica, J. M., Eppinger, B., Heekeren, H. R., Crone, E. A. & van Duijvenvoorde, A. C. K. (2024). Observational reinforcement learning in children and young adults. npj Science of Learning. https://doi.org/10.1038/s41539-024-00227-9

q3 · i? · causal · r2

Mixed-effects general linear model of choice accuracy in 30 children and 30 young adults performing the probabilistic learning task, controlling for intelligence. The model showed "significant main effects of learning condition (β = 0.12, t = 5.2, p < 0.001)", with no age × condition interaction (p = .9).

"The results of this analysis (see Supplementary Table 1 for full model output and Fig.2a for visualization) showed significant main effects of learning condition (β = 0.12, t =5 . 2 ,p < 0.001)"

• Adults outperform children in probabilistic learning accuracy and show greater accuracy improvement across trials in both learning conditions — related
• Choice behavior is more value-driven in the observational than individual learning condition, and adults show higher choice specificity than children — related
• Observational learning yields high performance early in learning while individual learning improves gradually across trials — related
