Problem:
A manner I have acquired is holding the door for someone walking in behind me. The physical antecedent would be someone walking up to a door behind me or while I'm out. The behavior would be to hold the door for that person. The person then walks into the building. The social contingencies would be the person walking up behind you close to you while entering and exiting a building. The behavior would be to stop the door from closing on the person walking up. The consequence would be the person smiling and saying thank you, reinforcing the action. This behavior can also encourage others to hold the door because I modeled the behavior, and the other people witnessed the reinforcement.
