Step 1: Concept Identification:
The question presents a behavior modification system grounded in operant conditioning principles. The objective is to pinpoint the specific technique employed.
Negative Reinforcement: Behavior is increased by removing an unpleasant stimulus.
Differential Reinforcement: Reinforcement is applied exclusively to the correct response, while all other responses are ignored.
Modelling: Learning occurs through observing the actions of others.
Token Economy: A system where individuals receive "tokens" (e.g., badges, points, poker chips) for exhibiting desired behaviors. These tokens can subsequently be traded for valuable rewards or privileges, known as backup reinforcers, such as a bonus.
Step 2: Detailed Analysis:
The described scenario precisely aligns with a token economy.
The desired behavior is "timely food delivery."
The "tokens" are the "badges" awarded monthly, possessing no inherent value independently.
The "backup reinforcer" is the "annual bonus," which the badges can be exchanged for.
This methodology of acquiring tokens for positive behavior and later exchanging them for a reward constitutes the definition of a token economy.
Step 3: Conclusive Answer:
The behavioral technique utilized is a Token economy.
