I would like to conduct a study to capture customer's implicit responses (where responses occur before 500-600ms) to product names. Does qualtrics have a way to present an image for 600ms? Additionally, I'd like the image to presented later if the customer does not respond in the time allotted.
Qualtrics has a timing question that can display a page for a specified amount of time, then move on. However, to do this the way I expect you want to, you'll have to write JavaScript to display the images for a fixed amount of time using a setTimeout function.
