Observational learning occurs when people learn new behaviors by watching others. Three key studies demonstrated this:
1. Bandura's Bobo doll experiment showed that children who observed an adult acting aggressively towards a Bobo doll were more likely to mimic that aggressive behavior, while children who saw a neutral adult did not.
2. Experiments with animals like hummingbirds found that birds learned to use a new type of feeder faster when able to observe a "tutor" bird using it first.
3. Brain scans show our brains activate in similar ways both when performing an action and when watching someone else perform it, suggesting we mentally rehearse observed behaviors.
