Why use open-ended questions? This chapter provides an up-to-date overview on the use of open-ended questions in novel rapid sensory methodologies and the potential applications in which they could provide unique benefits. Next, the step-by-step process is described (from task performance to analysis) with its pros and cons, with important considerations to follow. Examples with data from real, recently published case studies are provided to illustrate all the points raised in the chapter. Finally, the future trends of open-ended questions are discussed: Are social media currently useful for sensory science? How can the benefits of open-ended questions be boosted?
