The patterns of conditioned taste aversion (CTA) and of some other types of behaviour were compared in adult male and female Wistar rats. Correlations between the CTA variables, on the one hand, and those of the exploratory and defensive behaviours, on the other, were shown. Females displayed initially less expressed CTA and more rapid its extinction than males. While tested in the open field, in a six-arm radial maze and in a special enclosed cubic chamber with holes in its vertical walls the females demonstrated higher levels of exploratory and locomotor activities with lower levels of emotionality and defensive behaviour than males. Sex differences were revealed in correlations between variables of CTA and behavioural responses under study. Thus, CTA patterns appear to be one of the manifestations of sexual dimorphism in non-reproductive behaviour.
在成年雄性和雌性Wistar大鼠中比较了条件性味觉厌恶（CTA）模式和其他一些行为类型。结果显示了CTA变量与探索性和防御性行为变量之间的相关性。雌性大鼠最初表现出的CTA较弱，且其消退速度比雄性大鼠更快。在旷场、六臂放射状迷宫以及垂直壁上有洞的特殊封闭立方箱中进行测试时，雌性大鼠表现出比雄性大鼠更高水平的探索性和运动性活动，同时情绪性和防御性行为水平较低。在CTA变量与所研究的行为反应之间的相关性方面发现了性别差异。因此，CTA模式似乎是非生殖行为中性别二态性的表现之一。
