Final answer:
Implementing a token system requires immediate delivery of tokens following target behavior to reinforce desired behavior effectively.
Step-by-step explanation:
A token system is a behavior management technique that uses tokens as secondary reinforcers. These tokens can be exchanged for rewards or privileges. One practical consideration when implementing a token system is the ability of the change agent to deliver tokens immediately following the target behavior.
For example, in a study involving younger students, they received a 'quiet hands' token when they exhibited appropriate behavior and lost a token when they hit or pinched. The tokens could then be exchanged for minutes of playtime.
By delivering tokens promptly, the change agent reinforces the desired behavior and increases the effectiveness of the token system as a behavior modification tool.
