通过22代双向选择性育种，开发了味觉厌恶倾向和味觉厌恶抗性大鼠的品系，用于有效或无效的味觉厌恶条件适应性。本研究比较了这两条线的食物强化觅食在径向臂迷宫。这些线条，虽然在所有的测量上都不完全相同，但在学习迷宫方面同样熟练。这一发现支持了先前的迹象表明，选择性繁殖对学习产生了影响，这是高度具体的味觉厌恶条件性。因此，味觉厌恶条件适应性的基因差异不能归因于一般学习能力的基因差异。
Lines of taste-aversion-prone and taste-aversion-resistant rats have been developed through 22 generations of bidirectional selective breeding for efficient or inefficient taste-aversion conditionability. The present study compared these two lines on food-reinforced foraging in a radial-arm maze. The lines, although not identical on all measures taken, were equally adept at learning the maze. This finding supports prior indications that selective breeding has exerted an effect on learning that is highly specific to taste-aversion conditionability. Therefore, the genetically based line differences in taste-aversion conditionability cannot be attributed to a genetic difference in general learning aptitude.
