Adiscriminative stimulus is:
1) a stimulus in the presence of which a response will be reinforced
2) a stimulus in the presence of which a response will not be reinforced
3) a stimulus in the presence of which a response will be placed on extinction
4) a stimulus that cues respondent behavior to occur

The correct answer is option 1. a stimulus in the presence of which a response will be reinforced
