Description
Haoqun Zhang and four co-authors pair eye tracking with taste panels for three red bean and coix seed drinks. Self-report scores can bend under memory and wording ease, so the team also logged where eyes lingered on the answer scale. Twenty-four volunteers rated scent, taste, feelings, and liking for each drink.
The score a person picked and the score their gaze held longest agreed strongly, and both ranked the drinks in the same order. Gaze scores, though, swung too widely person to person to swap for picked scores. Warmth and sweetness tracked with pleasant feelings and with liking across both read types. One feeling word, good-natured, clung most steadily to liking, which marks gaze as a helpful side channel.
