性行为当前的含义 3:
生殖行为 |
|
低等哺乳动物的生殖行为 |
|
|
在低等哺乳动物，性行为稳定地受到一些特定的生理机制所调节。在某一个特定的可能受精的时候，雄性动物和雌性动物相互对特定的“性信号”行为做出反应，并因而开始以这样一种方式相互影响，即将雄性和雌性性细胞配送到一起。例如，雄性动物可以骑跨雌性动物，它们的性器官可以交接在一起，并且雄性动物将精液射入雌性动物体内，在那里完成受精的过程。不过，只有当雌雄双方都接纳了必要的“性信号”的情况下，整个的行为过程和行为反应才能够完成。雄性动物和雌性动物的性行为必须相互在每一个步骤上和按照非常特殊的方式得到强化。低等哺乳动物是“程序式”达到影响受精过程的，而且如果没有这种相互的强化过程，它们的性行为就会中断甚至不能持续下去。换一句话说，这就意味着低等哺乳动物的性行为并不是“本能控制式的”（即身体内部指令性完全控制的）。与之不同的是，它们的性行为是在发生性行为的当口适应某种刺激时被“构建的”或被“整合在一起的”。

Current Meanings of the Term 3:

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. |
