In Differential Reinforcement, what two dimensions are typically considered when evaluating responses?

• A. Rate and Type
• B. Latency and Magnitude
• C. Duration and Force
• D. Frequency and Timing

Answer: (A)

In Differential Reinforcement, you assess both how often a behavior occurs and what form it takes. The rate (or frequency) shows whether the behavior is happening at the level you’re targeting, while the type (topography) identifies the exact form of the behavior you want to reinforce. Together, these dimensions let you reinforce the specific shape of the response and the quantity of its occurrence, shaping the behavior toward the desired pattern and reducing reinforcement for undesired forms.

For example, if you want a dog to greet politely, you reinforce a target polite greeting only when it happens at the set rate you specify and in the correct, desired form. You ignore or withhold reinforcement for other greetings, which helps shape both how often the behavior happens and what it looks like. Other measures like how fast it happens after a cue or how strong the response is can be informative in other contexts, but rate and topography are the two core dimensions typically considered in differential reinforcement.
