Learning Alone vs. Together
As the experiment progressed, researchers noticed something interesting. Zuri and Malik both performed better when they could watch their peer first. But Malik improved more steadily over time, especially when learning from his own choices. Zuri, on the other hand, showed strong performance early on when watching others but didn't improve as much when learning alone.
During one of the trials, Zuri confidently chose a shape she believed would earn her points. She had watched her peer select it earlier and receive a reward. But this time, when Zuri made the same choice, she lost points instead. This is an example of vicarious reinforcement, where seeing someone else get rewarded makes the observer more likely to repeat the behavior.
This moment triggered what psychologists call a negative prediction error: The outcome was worse than Zuri expected. Her brain had predicted a reward, but the result contradicted that expectation. In the study, such errors were shown to activate specific brain regions, especially the dorsal medial prefrontal cortex (dmPFC), which helps us adjust our behavior based on unexpected outcomes.
For Zuri, this miscalculation became a powerful learning moment. Although she was younger and her brain didn't respond as strongly as Malik's, the experience still helped her recalibrate her expectations. She began to realize that just because something worked for someone else didn't guarantee it would work for her. This subtle shift in understanding is part of what makes observational learning so complex and valuable.
