- Reward magnitude influences reinforcement learning efficiency in naive mice.
- Large rewards enhance learning efficiency through effects on within-session and across-session learning and task engagement.
- Ventral striatal dopamine release duration and magnitude scale with reward sizes.
- Prolonged optogenetic enhancement of dopamine reward responses partially replicates benefits of large rewards.
- Dopamine signaling mediates task engagement in proportion to absolute reward magnitude.
