Short CommunicationRATA questions are not likely to bias hedonic scores
چکیده انگلیسی


- Hedonic scores were not biased by concurrent elicitation of sensory data using RATA questions.
- Results were consistent across different product categories.
- Concurrent use of RATA questions improved discrimination of hedonic scores in 5 of the 8 studies.

Concurrent elicitation of hedonic and sensory information from consumers helps to identify the sensory attributes that drive consumer preferences. However, there is a risk that asking consumers about specific sensory characteristics can bias their hedonic responses. This research extends previous work by investigating if concurrent use of rate-all-that-apply (RATA) questions, a variant of CATA questions is associated with bias of the hedonic scores. RATA questions extend CATA questions by requiring consumers to also rate the intensity of the terms that are applicable for describing samples ('high', 'medium' and 'low'). In eight consumer studies (n = 560) across five product categories there was no evidence of concurrent use of RATA questions influencing hedonic scores. When RATA questions were used concurrently with a hedonic question there was a strong tendency for greater hedonic discrimination between samples (5 of 8 studies). This suggested that the discriminative capacity of the hedonic question was increased by inclusion of the RATA question, a result that could be attributable to the RATA question increasing consumers' engagement and attention to the task. Further research is required to confirm this result and tentative explanation.
