• 9-Point hedonic scale
• Words vs numbers
• Cross cultural
• Rank rating
• Serial monadic

American, Chinese, Thai and Mexican consumers were required to assess products on two types of 9-point hedonic scale. One type, the 'words only' scale, consisted of the traditional verbal labels to which the numbers 1-9 are later attributed for numerical analysis. The second type, the 'numbers only' scale was a numerical scale ranging 1-9, along with the appropriate information indicating the directions of liking vs disliking. For the same stimuli, consumers used the 'words only' and 'numbers only' scales differently, indicating that the data from the two scales were not directly comparable. This was found for both the rank-rating and serial monadic protocols. With the latter protocol, consumers sometimes gave responses on the 9-point hedonic scale that were inconsistent with their rankings of liking. There was a strong tendency for the mean range of responses for the 'words only' scale to be less than for the 'numbers only' scale.
