Kids articulate themselves in a simpler manner than adults, and may have difficulty recognizing or expressing complex thoughts or feelings. This is why in-person interviews/focus groups with kids remain a popular and necessary part of any youth-focused research toolbox as we’re able to observe kids’ emotions and provide our clients with a more complete picture and thorough understanding of the topic at hand. Online survey research offers some great tools for measuring kids’ reactions to products, advertising, etc., but it doesn’t tell the whole story. This case study will showcase copy testing conducted with kids using facial expression technology to not only measure kids’ expressed opinions to advertising in a traditional online survey, but observe (and code) their emotions to that advertising.
