Free sorting lets subjects define their own perceptual similarity criteria
Evidence
Free sorting requires subjects to create groups containing stimuli that are perceived similar, based on their own criteria. In addition, they can be asked after the sorting task to describe each group of stimuli with verbal descriptors. This a posteriori labelling is assumed to facilitate the interpretation of perceptual dimensions during the analysis (Cartier et al., 2006). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 945
