q3 i? Positive and negative learning rates differed significantly across learning conditions (β = 0.75, t = 3.4, p < 0.001, main effect of valence), with higher rates for positive (median = 0.78) than negative outcomes (median = 0.2). → Rodriguez Buritica 2024

q3 · i? · causal · r2

Robust mixed-effects model on fitted learning rates from the double-update Q-learning model across age groups and conditions. Valence showed "main effect of valence" with positive median = 0.78 versus negative median = 0.2; no condition, age, or interaction effects (all p's > 0.7).

"Findings showed that positive and negative learning rates differed signi ficantly across learning conditions (β =0 . 7 5 ,t =3 . 4 ,p < 0.001, main effect of valence) with both learning rates were higher for positive (median = 0.78) than negative out- comes (median = 0.2)."

Discussion¶

Learner Variables¶

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

• Choice behavior is more value-driven in the observational than individual learning condition, and adults show higher choice specificity than children — related
