A behovior is more likely to occur in the presence of a porticular stimulus (we coll this the discriminative stimulus or SD) because the behavior has been reinforced only when the SD was present" is the definition of: Reinforcement Simulus Control Punishment Tronsfer Trial

## Step 1<br />The problem presents a definition and asks us to identify the term that best fits this definition. The definition describes a situation where a behavior is more likely to occur in the presence of a particular stimulus (the discriminative stimulus or SD) because the behavior has been reinforced only when the SD was present.<br /><br />## Step 2<br />We need to match this definition to the options provided: Reinforcement, Stimulus Control, Punishment, and Transfer Trial.<br /><br />## Step 3<br />The definition aligns with the concept of "Stimulus Control". In psychology, stimulus control refers to the influence that a stimulus has on the likelihood of a particular response occurring. In this case, the discriminative stimulus (SD) is the stimulus that is present when the behavior is reinforced, making the behavior more likely to occur in its presence.
