Temporal check-all-that-apply (TCATA)
Eating and drinking food or beverages usually extend over a time period of seconds to minutes. How sensations evolve over time is important in some product categories, but not well captured by static sensory methods. The temporal check-all-that-apply (TCATA) method captures how several product attributes simultaneously evolve over time. This chapter covers important considerations regarding the choice of assessor type, product set, and attributes. It describes how to design and conduct the TCATA study. The data analysis section addresses pre-processing steps, assessor performance evaluation, and visualization of the product’s temporal profile, as well as multiple analytical approaches, including count analysis, factorial design analysis, and penalty-lift methodology for linking temporal perceptions to consumer acceptance. A beer case study demonstrates the application of TCATA in real sensory research.
