What Is Stimulus-Based Conversation?
Stimulus-based conversation (SBC) is the speaking component of the PSLE English Oral
examination where you are shown a photograph and asked a series of questions
based on it. The examiner uses the picture as a starting point for a
short conversation that goes beyond what you see in the image.
Unlike other parts of the PSLE English paper that test reading and writing, a SBC
assesses how well you can observe, think, and express your ideas clearly and
concisely. You will need to describe what is happening in the picture, share your
own experiences related to the topic, and give your opinion on broader questions.
In this article, we will explain how SBC works and share 5
strategies
to help you speak confidently and score well.
PSLE Stimulus-Based Conversation Format
SBC is part of English Paper 4: Oral Communication, which carries a new total of 40 marks from 2025. The SBC section alone is worth 25 marks, making it the largest component of the oral examination. The remaining 15 marks are for Reading Aloud.
- You will be shown a real-life photograph of people in a specific setting or activity.
- The photograph does not contain any text or captions.
- You must interpret the image on your own. The examiner will ask three or more questions during the conversation.
The Reading Aloud passage and the SBC picture are no longer thematically linked, so the photograph may be on an entirely different topic from the passage you read.
What Does Stimulus-Based Conversation Assess?
SBC assesses how well you can observe a visual, think critically, and communicate
your ideas clearly in spoken English. It is an important part of the Primary 6 English assessment
because it reflects how students process and respond to real-world situations.
The examiner is looking at several skills during the conversation:
- Your ability to describe and analyse what you see in the photograph
- How well you connect the topic to your own personal experiences
- Whether you can express opinions and support them with reasons
- Your fluency, pronunciation, and confidence when speaking
- How naturally you respond to follow-up questions without memorised scripts
The key difference between SBC and other oral components is that it rewards thinking on your feet. What matters most is a genuine conversation, not rehearsed answers.
How Stimulus-Based Conversation Questions Work
The examiner follows a structured flow of questions, starting with the picture and gradually moving into broader discussion. Here is how the questions typically progress:
| Question Type | What It Asks | Example |
|---|---|---|
| Picture-based | Describe what you see in the photograph, including what the people are doing and how they might be feeling. | "What do you think the people in the picture are doing?" |
| Experience-based | Share a personal experience related to the topic or situation shown in the picture. | "Have you ever done something like this before? Tell me about it." |
| Opinion or critical thinking | Give your views on a broader question connected to the theme of the picture. | "Why do you think this activity is important for families?" |
The first question will always be about the picture. The questions that follow build on the
same theme but ask you to go deeper by drawing on your own life and forming opinions.
Each answer should be more than one or two sentences. Aim for thoughtful,
well-developed responses.
Stimulus-Based Conversation Strategies
Here are five strategies to help you perform well in SBC:
1. Observe the Picture Carefully Before Speaking
Take a few moments to look at the whole photograph before you start
talking.
Notice the people, their facial expressions, body language, the setting, and any objects or
details in the background. These observations give you material to draw from when answering
the first question.
Ask yourself:
- Who are the people in the picture and what are they doing?
- Where does the scene take place?
- How do the people seem to be feeling, and what clues tell you that?
A strong first answer sets the tone for the rest of the conversation, so it is worth spending a few seconds thinking before you speak.
2. Go Beyond Description
Do not simply list what you see in the picture.
After describing the scene, add your interpretation. Explain why you think
the people are doing what they are doing, or how they might be feeling and why.
For example, instead of saying, "The children are playing in the park," you could say, "The
children look like they are having fun playing in the park. They are laughing and chasing
each other, which suggests that they are enjoying themselves."
Adding this layer of inference shows the examiner that you can think beyond the surface of
the image.
3. Prepare a Bank of Personal Experiences
Think about a range of common topics ahead of time and recall relevant personal
experiences for each one.
PSLE SBC pictures often feature everyday themes such as family activities, school events,
helping others, outdoor activities, and community life.
You do not need to memorise scripts. Instead, have a few real experiences in mind that you
can adapt to different questions. If the picture shows a family cooking together, for
instance, you might talk about a time you helped prepare a meal at home.
Having these experiences ready means you will not be caught off guard when the examiner
asks you to share something personal.
4. Support Your Opinions with Reasons
Whenever you give an opinion, follow it with at least one clear reason.
Simply saying "I think it is important" is not enough. The examiner wants to hear why you
think so.
A useful structure is:
- State your opinion clearly.
- Give a reason to support it.
- Add an example if you can.
For instance, if asked, "Why is it good for families to spend time together?", you could say, "I think spending time together helps family members understand each other better. When my family goes for walks on weekends, we talk about our week, and often suggest ideas to help each other resolve any problems that arise. These discussions have made us grow closer to one another."
5. Speak Naturally and Stay on Topic
Focus on speaking at a comfortable pace with clear pronunciation rather than
rushing to say as much as possible.
It is better to give a well-thought-out answer than a long, unfocused one.
If you do not understand a question, it is perfectly fine to ask the examiner to repeat it.
Stay calm and listen carefully to each question so your answer addresses what was actually
asked.
Avoid going off the topic or bringing in unrelated points, as this can make your response
sound disorganised.
Common Themes in Stimulus-Based Conversation Pictures
PSLE SBC photographs typically feature relatable, everyday scenarios. The list below is not exhaustive, but knowing what themes commonly appear helps you prepare experiences and ideas in advance.
| Theme | Examples |
|---|---|
| Family and home | Cooking together, cleaning the house, celebrating a birthday |
| School life | Group projects, sports day, recess activities |
| Helping others | Volunteering, helping an elderly neighbour, community clean-ups |
| Outdoor and nature | Visiting a park, gardening, exploring nature reserves |
| Social situations | Sharing with friends, resolving a disagreement, working as a team |
| Learning and hobbies | Reading, art and craft, learning a musical instrument |
| Food and health | Choosing healthy food, exercising together, preparing lunch, visiting a market |
| Community and culture | Attending a festival, visiting a museum, neighbourhood events, interacting with people from different backgrounds |
You do not need to predict the exact picture, but practising how to talk about these themes means you will always have something meaningful to say.
How to Improve at Stimulus-Based Conversation
1. Practise Describing Photographs Out Loud
Choose any photograph from a newspaper, magazine, or online source and practise
describing it clearly. Talk about who is in the picture, what they are doing, how
they might be feeling, and what the setting looks like. You may organise your
description in a logical order, e.g., from left to right, foreground to background,
or in a clockwise direction.
You can also record yourself on your phone and listen back to check whether your
descriptions are clear and detailed enough. This helps you spot habits like
speaking too quickly, repeating yourself, or giving answers that are too short.
2. Have Conversations About Everyday Topics
Talk with your parents, siblings, or friends about topics that commonly appear in SBC.
Discuss what you did over the weekend, how you felt about a school event, or what you think
about a topic in the news. Students from Primary 3 onwards can start
building this habit early, as oral communication is assessed at every level.
These do not have to feel like practice sessions. Simply taking an interest in the people
around you and genuinely engaging in conversation builds the same skills the exam is looking
for. Research has also shown that children who hear more talk from adults produce
more speech themselves, reinforcing the value of regular conversation at home.
The more comfortable you are expressing your thoughts out loud, the more natural it becomes
during the exam. So what does this mean? Keep talking!
3. Read Widely to Build Vocabulary and Ideas
Reading exposes you to different topics, vocabulary, and ways of expressing ideas. Students
who read widely tend to have more to say during SBC because they can draw on a broader
range of knowledge.
Research has also found that there is an increasingly high relationship between reading and speaking skills, with students who
develop large reading vocabularies also developing stronger speaking vocabularies.
Fiction, non-fiction, news articles, and even continuous writing
model essays all help expand the ideas and language you can use in conversation.
4. Learn from Model Responses
Look at sample SBC answers and notice how strong responses are structured. They typically
start with a direct answer, add supporting details or reasons, and end with a personal
connection or opinion.
Practising this structure helps your answers feel organised and complete without sounding
scripted.

Frequently Asked Questions (FAQs)
Stimulus-based conversation uses real-life photographs of people in a specific setting or activity. The pictures do not contain any text or captions, so you must interpret the image on your own. Common themes include family activities, school life, helping others, outdoor scenes, social situations, learning and hobbies, food and health, and community events.
Practise describing photographs out loud on a regular basis and record yourself to check whether your answers are clear and detailed. Have genuine conversations with your parents, siblings, or friends about everyday topics, as this builds the same speaking skills the exam tests. Reading widely across fiction, non-fiction, and news articles also gives you more vocabulary and ideas to draw on during the conversation.
The examiner asks three or more questions that follow a structured flow. The first is always picture-based, asking you to describe what the people are doing and how they might be feeling. The second is usually experience-based, where you share a personal experience related to the topic. The final question asks for your opinion or requires critical thinking on a broader issue connected to the theme.
Both are part of PSLE English Paper 4: Oral Communication, but they test different skills. Reading aloud is worth 15 marks and assesses pronunciation, fluency, and expression. Stimulus-based conversation is worth 25 marks and assesses your ability to observe a photograph, think critically, share personal experiences, and express opinions in a natural conversation. The two sections are no longer thematically linked, so the picture may be on an entirely different topic from the passage.
