Paired comparison lets flash profiling skip time-consuming attribute training.

Evidence

Flash profile (Delarue and Sieffermann, 2004): The individual elicitation approach of freechoice profiling and the pair-wise comparative evaluation technique are combined in flash profile. During the descriptive analysis process, all stimuli are compared in pairs, which apparently removes the need for a phase of familiarization and a phase of individual training with the attributes. In addition, flash profiling assumes that assessors are familiar with descriptive analysis, which ensures that discriminant attributes can be generated in a short time. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 941
