※ 引述《slin (slin)》之銘言：
: Adult female rats who have never before encountered rat pups
: will start to show maternal behaviors after being confined with a
: pup for about seven days. This period can be considerably shortened
: by disabling the female’s sense of smell or by removing the scent-producing
: glands of the pup.
: Which of the following hypotheses best explains the contrast described above?
題意:
成年但還未接觸幼鼠 的母鼠 如果把他們和幼鼠關在一起的話 大約七天會有母性的行為
如果說 把成年母鼠的嗅覺除去 或是把幼鼠分泌氣味的拿掉
母鼠會快一點去照顧幼鼠 (就是說不用到七天 就會去發揮母愛了)
contrast: 有嗅覺 七天 <--->沒嗅覺 較短時間 我的看法是對比在這拉
可以聞到幼鼠的氣味 應該會較快發揮母愛 為啥還拖比較久 --->找解釋
: (A) The sense of smell in adult female rats is more acute than that in rat
: pups.
成年母鼠的嗅覺較敏銳 ...無關 如果較敏銳的話 為啥拿掉嗅覺後 反而可縮短
: (B) The amount of scent produced by rat pups increases when they are in the
: presence of a female rat that did not bear them.
幼鼠分泌的氣味 會增加 ...無關
如果可以解釋的話 為什麼去除掉母鼠的嗅覺器官 和幼鼠的scent-producing glands
反而可縮短呢
: (C) Female rats that have given birth are more affected by olfactory cues
: than are female rats that have never given birth.
有生過的母鼠較易受影響
題目沒有拿生過 和未生過的做比較
: (D) A female rat that has given birth shows maternal behavior toward rat pups
: that she did not bear more quickly than does a female rat that has never
: given birth.
同C
: (E) The development of a female rat’s maternal interest in a rat pup that
~~~~~~~~~~~~~ 發展 和時間相關 要注意
: she did not bear is inhibited by the odor of the pup.
~~~~~~~~~~~~~
聞到味道了 所以受限 那聞不到味道 變快了 (好像可以理解)
概念大概是 成年母鼠 聞到幼鼠散發的氣味 知道他不是自己的小孩 所以不會去照顧
所以時間被拉長了 聞不到味道 不知道是不是自己的小孩 看到幼鼠 就先去照顧了
: 答案是E
: 這題我跟我朋友討論了很久,我們對於題目的意思,以及問題中的"contrast",還有正確
: 答案為什麼是E,都有所疑惑,是不是可以請版友不吝告知,謝謝大家了,,,
