Stimuli

Stimuli allow you to enrich your study with visual, interactive, and multimedia content. You can add images, videos, comparisons, embeds, links, and randomized stimulus sets directly within your Topic Guide. Stimuli are attached to questions and research objectives to define what participants see before answering.

Overview

Conveo supports the following stimulus types:

• Single Image
• Image Comparison
• Randomized Stimuli
• Uploaded Video
• YouTube Video
• Figma Design
• Canva Embed
• Link

Each type serves a different research purpose, from simple concept testing to advanced monadic designs and interactive prototype evaluations.

Adding a Stimulus

To add a stimulus to a question or research objective:

1. Navigate to your Topic Guide.
2. Open the question where you want to display content.
3. Click Add Stimulus.
4. Select Create Stimulus.
5. Choose the desired stimulus type.
6. Configure the stimulus.
7. Click Attach to link it to the question.

Once attached, the stimulus will appear as part of the interview flow.

​

Single Image

Upload one image to display alongside a question. Typical use cases:

• Concept visuals
• Packaging designs
• Advertisements
• Product mockups

You can upload language-specific versions if your study includes multiple participant languages.

​

Image Comparison

Display multiple images side-by-side for direct comparison. Typical use cases:

• A/B testing
• Logo comparisons
• Before/after testing
• Design preference evaluation

Participants view all images simultaneously and respond to a comparative question.

​

Randomized Stimuli

Use randomized stimuli when you need to systematically control which respondents see which concepts, messages, or variations. Randomization ensures:

• Equal and unbiased exposure across variants
• Reduced order effects and presentation bias
• Statistically valid comparisons between concepts
• Cleaner performance measurement per stimulus

This approach is particularly valuable when testing multiple concepts while maintaining research rigor.

​

Monadic vs Sequential Monadic

Set Number of stimuli to show per participant (above the table) to control how many variants each respondent evaluates: Conveo automatically:

• Randomizes selection
• Balances exposure evenly
• Ensures unbiased distribution

No manual balancing setup is required.

​

The Stimulus Table

Randomized stimuli are configured in a table editor. Each row is one concept (variant), and the columns describe how that concept should show up in the interview. There are two ways to add concepts:

• Drop images onto the dropzone at the bottom of the table to bulk-upload. Each image (JPG or PNG, up to 10 MB) creates its own row, with the file name used as the concept name — the fastest way to seed a new stimulus when you already have the assets ready.
• Click Add concept to create a blank row and fill in the cells manually. Use this for any asset type the dropzone doesn’t support — videos, YouTube links, Figma prototypes, Canva designs, website links, or PDFs.

You can mix asset types in the same stimulus — for example, one row can be a YouTube video while another is an uploaded image. Click any asset cell to swap the media for that row:

​

Parameters

Parameters let a single question text adapt to whichever concept is being shown. You define a placeholder once in the question, and each concept supplies its own value.

1. In the stimulus table, click the + button in the column header row and name the parameter (e.g. brand, price, tagline). A new column appears.
2. Fill in a value for each concept in that column.
3. In the question text, follow-up context, or multiple-choice options of any question this stimulus is attached to, reference the parameter with double brackets: [[ tagline ]]. Conveo highlights these placeholders in violet so you can spot them at a glance.

At interview time, the placeholder is replaced with the value from the concept the participant is currently seeing. For sequential monadic studies, the substitution follows the participant through each concept, so the same question reads naturally for every variant. Example:

• Question: “Does this brand feel [[ tagline ]] to you? Why or why not?”
• Ruby concept, tagline = "Bold and timeless" → “Does this brand feel Bold and timeless to you? Why or why not?”
• Ocean concept, tagline = "Deep and trusted" → “Does this brand feel Deep and trusted to you? Why or why not?”

To rename a parameter, hover the column header and click the pencil icon. To remove a column, click the trash icon — this also removes the values from every row.

​

Groups (Mutual Exclusivity)

Groups let you organize concepts into sets. For each participant, Conveo picks at most one variant from each set, ensuring balanced coverage across every dimension you’re testing. To create a group, click New group below the table, then drag concept rows into it. You can also drag a row onto an existing group to join it, or drag it out to ungroup. Groups are color-coded so you can tell them apart at a glance. Click the group name to rename it. Example use cases:

• Mutually exclusive variants: Concept A and Concept B are two versions of the same ad. Put them in one group so no participant sees both.
• Crossed designs: One group holds brand variants, another holds price variants. Each participant sees one from each group, giving you clean per-dimension comparisons.

During an interview, Conveo randomly picks one concept per group for each participant, up to the number of stimuli you’ve set per participant. Each ungrouped concept counts as its own one-variant group. Once your table is set up, click Attach at the top of the editor to link this stimulus to your question or research objective.

Multi-Language Support

If your study includes multiple participant languages, you can upload language-specific versions of each stimulus so participants see content in their selected language. Each asset has a default uploaded file and an optional Localized Assets section — open it via the Add translations button on the asset card, or the globe icon on randomized stimulus rows. Then click Add translation, choose the target language (e.g., French), and upload the localized version of the asset. During interviews, Conveo automatically shows the version that matches the participant’s language — no duplicate questions or extra setup needed. If a translation is missing, the default version is shown instead. Translations don’t affect how variants are balanced — Conveo picks the variant for each participant before applying their language, so randomized and sequential monadic designs behave identically across markets. For reliable cross-market results, upload all translations before launching fieldwork and verify every variant has the localized versions you need.

​

Translating Parameter Values

Parameter values (the text that replaces [[ key ]] placeholders) are also translatable. In the stimulus table, click the globe icon next to any parameter cell to open the translations popover. Enter a value per study language, or click Generate translations to have Conveo translate the primary value automatically. At interview time, Conveo picks the value that matches the participant’s language — falling back to the primary-language value when a translation is missing.

​

Best Practices

• Use clear naming conventions for stimulus sets
• Upload translations before launching multi-language studies
• Use grouping to control experimental structure
• Avoid showing too many stimuli per respondent to reduce fatigue
• Match the stimulus type to your research objective
