We often focus our analysis on a specific range of behavior (client in office, classroom, experimental session) and don't attend to other situations. Behavioral Contrast in multiple schedules and the Matching effect in concurrent schedules are examples of situations where the "value" or "power" of a reinforcer depends on what is going on with other sources of reinforcers.

1. Describe a situation in your professional area (or your daily life) which would correspond to a multiple schedule and identify a response and reinforcer that you would expect to see either a positive or negative behavioral contrast effect.

2. Describe a situation in your professional area (or your daily life) which would correspond to a concurrent schedule and identify a response and reinforcer that you would expect to see a matching effect.
