Questions and Answers
What is a stimulus? Give two examples that are not from the text.
A stimulus is the people, animals, objects, and events currently present in one's immediate surroundings that impinge on one's sense receptors and can affect behaviour. Examples: 1. The sugar, flour, oven, oven mitts, mixing bowls, the smell of cookies when a baker is baking cookies. 2. A pencil, notebook, laptop, iPod music, table and other people when a student is in a library studying.
Define stimulus control.
Stimulus control refers to the degree of correlation between the occurrence of a particular stimulus and the occurrence of a subsequent response.
What is the difference between a stimulus and a discriminative stimulus?
A stimulus is a person, place, or thing in someone's sense receptors, while a discriminative stimulus is a specific stimulus in the presence of which a response will be reinforced.
Describe an example of a stimulus that is an SD for one behaviour and an SΔ for a different behaviour.

Study Notes
Stimulus and Examples
- A stimulus comprises individuals, animals, objects, and events that affect behavior by interacting with sense receptors.
- Examples of stimuli:
- While baking, a baker engages with sugar, flour, mixing bowls, and the smell of cookies.
- A student studying in a library interacts with a pencil, notebook, laptop, and ambient music.
Stimulus Control
- Stimulus control refers to the degree to which a specific stimulus correlates with the occurrence of a response.
Difference Between Stimulus and Discriminative Stimulus
- A stimulus can be any person, place, or thing that impacts perception, while a discriminative stimulus (SD) specifically signals the potential reinforcement of a response.
SD and SΔ Example
- An SD: A button in a fitting room labeled "push for assistance" triggers a response leading to help.
- An SΔ: A deceptive pop-up ad claiming "push for a chance to win" may introduce a virus, discouraging the response.
Stimulus Discrimination Training
- Involves reinforcing responses to an SD while extinguishing them for an SΔ, improving the individual's ability to distinguish between stimuli.
- Example: A child learning fine motor skills responds correctly to "do this" after demonstrated, indicating successful discrimination.
Effects of Stimulus Discrimination Training
- Results in good stimulus control, ensuring strong correlation between stimulus and response.
- Leads to stimulus discrimination where responses are correctly triggered by specific stimuli (SD) and not by others (SΔ).
Stimulus Generalization
- Refers to a situation where a response reinforced in the presence of one stimulus becomes probable in the presence of similar stimuli.
- Example: A child says "doggie" for various breeds of dogs after learning about one type.
Selection of Stimulus as SD
- Important considerations when selecting a stimulus to act as an SD:
- Is the stimulus distinct across multiple dimensions?
- Is it only presented when the desired response should manifest to minimize confusion?
- Does it capture the individual's attention effectively?
- Are there any unintended responses that the stimulus might provoke?
Establishing a Personal SD
- Example chosen for establishing an SD: A no smoking sign to help a friend quit smoking indoors.
- Questions addressing the sign:
- It stands out visually and conveys a specific prohibition.
- The sign will only be displayed in the home when the desired behavior (not smoking) should occur.
- The sign is noticeable, making it likely that the friend will heed it.
- The sign does not trigger any unwanted responses related to smoking behavior.
