A comparison of serial monadic and attribute-by-attribute descriptive analysis protocols for trained judges

“…It would appear the prior training had established sufficient intensity exemplars to attain an accuracy level comparable to the attribute-byattribute method. This is in contrast to the results obtained with untrained judges (Ishii et al, 2007).…”

“…This observation is indeed illustrated in Table 6 as the mean experimental session lengths to complete an experimental session for the initial two sessions and final two sessions were significantly shorter for the serial monadic method than for the attribute-by-attribute method (ttest, p 6 0.0002). This contrasts with subjective reports from untrained subjects who found the attribute-by-attribute protocol easier (Ishii et al, 2007).…”

“…Also, the fact that the serial monadic sessions ended up as being shorter in length, demonstrates their efficiency. This study and the previous study (Ishii et al, 2007) suggest that the attribute-by-attribute protocol was more suitable for naïve judges such as consumers, while after the sort of training that would be appropriate for a descriptive panel, the serial monadic protocol could be more suitable.…”

“…If the intensity of an attribute for the first food were to be forgotten while a later food was being assessed, it would not matter. Ishii, Chang, and O'Mahony (2007) reviewed the various studies that provided evidence for relative and absolute scaling strategies as well as their use in descriptive analysis (eg. Mazzucchelli & Guinard, 1999).…”

“…As the next logical step, it is important to consider what would happen if the experiment of Ishii et al (2007) were to be repeated with a sample of judges who had already established a set of intensity exemplars. Then, the two protocols might now be equivalent in their simplicity.…”
