What characterizes a discriminative stimulus?

• A. A cue that leads to a response only after it is presented
• B. A prompt that encourages multiple types of responses
• C. A negative consequence that diminishes behavior
• D. A generic signal used in interventions

Answer: (A)

A discriminative stimulus is characterized as a cue that indicates that a particular response will be reinforced or rewarded when it occurs in the presence of that stimulus. This means that the stimulus signals to the individual that a specific behavior is appropriate and will lead to a positive outcome. When a discriminative stimulus is presented, it activates a learned relationship where the subject associates that particular cue with the likelihood of a certain behavior being reinforced. This relationship encourages the individual to perform the associated response when they encounter that stimulus. For example, if a child learns that a specific sound or visual cue leads to receiving praise for saying "thank you," that cue becomes a discriminative stimulus for the desired polite behavior. In this context, the other options do not fully capture the definition or role of a discriminative stimulus. While a prompt that encourages multiple responses can guide behavior, it does not necessarily indicate reinforcement specific to one behavior. Similarly, a negative consequence that diminishes behavior refers to punishment rather than a cue for a response, and a generic signal used in interventions lacks the specificity and reinforcement connection inherent in the concept of a discriminative stimulus.
