Effects of d-amphetamine and scopolamine were investigated on either-way avoidance in two genetic lines. In the either-way task, the animal has the option to respond in either of the two directions available. Differences between the genetic lines were statistically significant under the effects of scopolamine, but were absent under the effects of d-amphetamine. It seems that scopolamine is more likely to disrupt responsiveness to visual stimuli in the low-avoidance line and this difference in responsiveness is influenced by bidirectional genetic selection.
研究了右旋苯丙胺和东莨菪碱对两个遗传品系双向回避反应的影响。在双向任务中，动物可以选择在两个可用方向中的任意一个做出反应。在东莨菪碱的作用下，遗传品系之间的差异具有统计学意义，但在右旋苯丙胺的作用下则不存在差异。似乎东莨菪碱更有可能破坏低回避品系对视觉刺激的反应性，而这种反应性的差异受到双向遗传选择的影响。
