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

You can define how many stimuli each respondent sees:
StimulusExplanation
MonadicEach respondent is shown one randomly assigned stimulus from the full set of uploaded stimuli. They evaluate only that single concept, ensuring unbiased, in-depth feedback without comparison effects.
Sequential monadicEach respondent is shown two or more randomly assigned stimuli, one at a time. The same evaluation questions are repeated for each stimulus, with the order randomized to reduce order bias and comparison effects.
Conveo automatically:
  • Randomizes selection
  • Balances exposure evenly
  • Applies grouping constraints
  • Ensures unbiased distribution
No manual balancing setup is required.

​
Uploading Variants

To add variants to a randomized stimulus, open the stimulus and upload each asset individually within the same stimulus set. Every file you upload is automatically added as a separate variant. You can continue adding multiple files (e.g., different creatives, concepts, or formats) to build your full test set in one place. For each variant, you can:
  • Assign a clear internal title
  • Upload the primary asset file
  • Add language-specific versions if needed
  • Apply grouping rules (if using mutual exclusivity)

​
Grouping (Mutual Exclusivity)

Stimuli can be grouped to prevent certain variants from appearing together. Example:
  • Stimulus 1 and Stimulus 3 should not appear in the same interview.
  • Assign both to the same group.
The system will randomly select one stimulus from that group per respondent.

​
Multi-Language Support

If your study includes multiple participant languages, you can upload language-specific versions of each stimulus to ensure participants see content in their selected language. Each stimulus variant contains a default uploaded file and an optional Localized Assets section, where you can add translations by selecting Add translation, choosing the target language (e.g., French), and uploading the localized version of the asset. During interviews, Conveo automatically displays the version that matches the participant’s chosen language, keeping the experience fully language-consistent without requiring duplicate questions or manual routing logic. If a translation is not provided, the default version will be shown. Translations work seamlessly across all stimulus types, including randomized, monadic, and sequential monadic designs, and do not affect exposure balancing, as variant selection occurs before language matching. To ensure reliable cross-market results, we recommend uploading all required translations before launching fieldwork, using clear and consistent naming conventions, and verifying that each stimulus variant includes all necessary localized versions.

​
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

​
Summary

Stimuli in Conveo enable you to:
  • Add visual and interactive content to questions
  • Compare assets side-by-side
  • Run advanced randomized concept tests
  • Support multiple languages
  • Control exposure logic and grouping
This flexibility allows you to design structured, scalable, and unbiased research experiences.
