Final answer:
The primary discriminative stimulus in negative reinforcement is the Establishing Operation (EO), which signals the availability of a possible negative reinforcement, making it the correct answer from the options provided.
Step-by-step explanation:
The primary discriminative stimulus in negative reinforcement is typically the presence of an aversive stimulus, which the individual seeks to escape or avoid. This aversive stimulus acts as a signal that a particular response will alleviate the negative condition, thereby increasing the likelihood of that response occurring again in the future. The terms mentioned, such as Establishing Operation (EO), Stimulus Delta (SD), Conditioned Stimulus (CS), and Response Reinforcer (RR), relate to various concepts in operant conditioning and learning. However, when considering the options provided:
- Establishing Operation (EO) refers to an environmental event that enhances the effectiveness of a reinforcer.
- Stimulus Delta (SD) is a term used to describe a stimulus in the presence of which a particular behavior is not reinforced.
- Conditioned Stimulus (CS) is a previously neutral stimulus that, after becoming associated with an unconditioned stimulus, eventually comes to trigger a conditioned response.
- Response Reinforcer (RR) is not a standard term used in operant conditioning.
Therefore, the Establishing Operation (EO) is typically considered the primary discriminative stimulus in negative reinforcement, as it sets the stage for a behavior to be negatively reinforced by signaling the availability of a possible negative reinforcement.
