“Marshmallow Test” Redux: New Research Reveals Children Show Better Self-Control When They Depend on Each Other
Children are more likely to control their immediate impulses when they and a peer rely on each other to get a reward than when they’re left to their own willpower, new research indicates. The findings appear in Psychological Science. The researchers say their experiments are the first to show that children are more willing to delay gratification for cooperative reasons than for individual goals.
How the Human Brain Solves Complex Decision-Making Problems
A new study on meta reinforcement learning algorithms helps us understand how the human brain learns to adapt to complexity and uncertainty when learning and making decisions. A research team succeeded in discovering both a computational and neural mechanism for human meta reinforcement learning, opening up the possibility of porting key elements of human intelligence into artificial intelligence algorithms. This study provides a glimpse into how it might ultimately use computational models to reverse engineer human reinforcement learning.
