The tests were conducted over two weeks in two sessions for each week. Consumers were given CATA questions to describe appearance, flavor and texture each with 5, 27, and 11 descriptors, respectively. This allowed the investigation of response time as a function of number of choices. Effects of choices presentation order (alphabetical for week1 and Williams design for week2) on the OJ sensory descriptions were also examined. The study was designed, organized and administered using Compusense\u00ae at-hand (Compusense Inc., Guelph, Canada).<\/p>\n<p>Consumer response time revealed that for the William design presentation order of choices, consumers took in average 4.54, 5.00 and 1.69 seconds more to answer CATA questions pertaining to appearance, flavor and texture attributes, respectively. However, product descriptions showed no significant differences between the designed and alphabetical presentations. Consumer response time was also investigated as a function of sample presentation order (Fig. 1). Not surprisingly, response time for CATA questions decreased as a function of sample presentation position within a session, showing the same effect on day2 of each week. Presentation position also had an impact on the number of choices made. The average number of descriptors chosen for flavor increased from 4.2 for the first sample tested to 4.8 for the 5th sample tested during week1\/session1.<\/p>\n<p>In conclusion, the time taken by consumers to answer CATA questions is impacted by individual variations and the order of the response options are presented in. However, overall product descriptions were not impacted by CATA descriptors presentation order.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-250\" src=\"https:\/\/secure.compusense.com\/wp-content\/uploads\/2017\/02\/Line-300x9.png\" alt=\"\" width=\"467\" height=\"14\" srcset=\"https:\/\/secure.compusense.com\/wp-content\/uploads\/2017\/02\/Line-300x9.png 300w, https:\/\/secure.compusense.com\/wp-content\/uploads\/2017\/02\/Line.png 548w\" sizes=\"(max-width: 467px) 100vw, 467px\" \/><\/p>\n<p>Meullenet, J.-F., Findlay, C.J., Tubbs, J.K., Laird, M., Kuttappan, V.A., Tokar, T., Over, K., &amp; Lee, Y.S.
