Mapping the behavior

Helmet Wearing Habit

Question: How can she effectively form a blue, span behavior?

• Start Small: Wear helmet to first class of the day

• Social Commitment: Ask a friend to wear a helmet

• Trigger: leave the helmet by the bike. Everytime she gets on the bike she sees the helmet. (No one steals helmets.)

Outcomes

• What worked– Leaving the helmet by the bike insured that she

could always find the helmet– Establishing a habit with a friend reinforced habit

creation– Starting small. In committing to wearing the

helmet only once a day, she allowed herself lapses in helmet wearing.

Next steps

• Buy a cooler helmet- Social deviance did play a small role in the motivation to wear a helmet

• Bike less- the helmet was uncomfortable and poor fitting, and thus required a physical effort to secure
