緒論 - 什麼是性行為? |

性行為當前的含義 3:
生殖行為 |
|
低等哺乳動物的生殖行為 |
|
|
在低等哺乳動物，性行為穩定地受到一些特定的生理機制所調節。在某一個特定的可能受精的時候，雄性動物和雌性動物相互對特定的“性暗示”行為做出反應，並因而開始以這樣一種方式相互影響，即將雄性和雌性性細胞配送到一起。例如，雄性動物可以騎跨雌性動物，它們的性器官可以交接在一起，並且雄性動物將精液射入雌性動物體內，在那裏完成受精的過程。不過，只有當雌雄雙方都接納了必要的“性信號”的情況下，整個的行為過程和行為反應才能夠完成。雄性動物和雌性動物的性行為必須相互在每一個步驟上和按照非常特殊的方式得到強化。低等哺乳動物是“程式式”達到影響受精過程的，而且如果沒有這種相互的強化過程，它們的性行為就會中斷甚至不能持續下去。換一句話說，這就意味著低等哺乳動物的性行為並不是“本能控制式的”（即身體內部指令性完全控制的）。與之不同的是，它們的性行為是在發生性行為的當口適應某種刺激時被“構建的”或被“整合在一起的”。 |

Introduction - What is sexual behavior? |

Current Meanings of the Term 3:
Reproductive Behavior |

Lower Mammals

|
In the lower mammals,
sexual behavior is firmly regulated by
certain specific physiologic controls.
At certain times when fertilization is
possible, males and females respond to
certain behavioral "cues" in each other
and thus begin to interact in such a way
that the male and female sex cells are
brought together. For example, the male
may mount the female, their sex organs
may be joined together, and he may
ejaculate into her body where
fertilization can then take place.
However, the entire sequence of actions
and responses can be completed only if
all necessary cues are received by both
partners. Male and female sexual
behaviors have to reinforce each other
at every step and in very specific ways.
The animals are "programmed" to effect fertilization, but the program breaks down or even fails to develop without such mutual reinforcement. This means, among other things, that the sexual behavior of these animals is not "instinctive", i.e., entirely directed from within. Instead, it is "built up" or "put together" in response to certain stimuli at the time of its occurrence. |
