味覺反應增強不是a scaling artifact

In the early 1990s, Bartoshuk and her colleagues noticed some individuals tested in the laboratory seemed to have an elevated taste response and took to calling them supertasters.

This increased taste response is not the result of response bias or a @scaling artifact@, but appears to have an anatomical/biological basis.

味覺反應增強不是a scaling artifact,反而似乎有解剖學或生物學的根據。

請問一下這裡的scaling artifact是什麼意思?



Supertasters were initially identified on the basis of the perceived intensity of propylthiouracil (PROP) compared to a reference salt solution. However, because supertasters have a larger sense of taste than medium or nontasters, this can cause scaling artifacts.

這一段的最後一句又出現了= =

    This increased taste response is not the result of response bias or a scaling artifact, but appears to have an anatomical/biological basis.

    這增強的味覺反應不是(反應偏好)或一個(評等尺度的人為產物)的結果, 反而顯示有解剖學或生物學的根據。

    response bias 反應偏好 ‑ 指每個人對口味的種類輕重有不同的偏好.

    scaling artifact 評等尺度的人為產物.(相對於有證據的科學實驗結果)

    請參考以下連結才能瞭解scaling artifact的意思:

    'This is incredible--we've stumbled across an artifact that nobody noticed.'

    The scaling error that Bartoshuk and Snyder observed is easy to overlook because it usually leads to null results.

    If there is, the chances are that the groups are using different scales [in making ratings], so the problem may be much worse than we thought."

    Using fungiform papillae as a gauge, Bartoshuk's group has found that, unlike traditional adjective-labeled scales, both magnitude matching and Green's LMS scale accurately reflect disparities between supertasters, tasters and nontasters. That's good news, not only because it verifies Bartoshuk's suspicions about adjective-labeled scaling techniques, but also because it provides a solution for researchers in other areas of psychology, who may not have a Rosetta Stone.

    ✱ Bartoshuk 原先用的是adjective-labeled scaling techniques 形容詞標示的尺度, 如‘沒味道, 有點鹹的, 中等鹹度, 很鹹的’… 標準因人而異而不客觀, 所以研究結果出問題, 就是因為用的是不夠仔細的科學評等方式, 所以造成scaling artifact, 評量尺度的人為產物, 指錯誤的研究結果.

    response bias 應翻成‘反應偏差’,是問卷專有名詞. 很抱歉失察! 版主是對的, 除了符合社會期待, 還有其他的狀況, 請參考

    這增強的味覺反應不是‘調查偏差’或‘評量方法’的結果, 反而顯示有解剖學或生物學的根據。
