(a) how would you classically condition an adventuresome 2-year-old to be more fearful of running across a busy street near her house?

You would condition this boy by using Negative Reinforcement, which means in order to get the boy to stop running in traffic you would add a consequence every time he does it. For example every time he runs into the street make him unload the dishwasher etc.

Very cool! free points wooo
