Changing unwanted behaviors using Pavlov's ideas can be tricky. Here are some challenges we might face:

1. Difficulties:

   • Conditioning complexities: It’s tough to clearly connect certain triggers with specific reactions.
   • Generalization: Bad behaviors can happen in different situations, making them harder to change.
   • Resistance: Some habits can be really strong and hard to break.

2. Possible Solutions:

   • Consistent reinforcement: Use steady and different rewards for the behaviors you want to encourage.
   • Gradual exposure: Slowly introduce new triggers to help weaken ties to the unwanted behavior.
