Comparison of three different shapes of behaviour in rats reveals following correlations: rats elaborating avoidance of closed space in response to cries of another individual (first group) significantly more frequently come into the centre of the "open field", exhibit greater alimentary activity in the new chamber in a state of moderate hunger and elaborate an alimentary reflex more readily as compared with the animals, which steadily prefer closed space (third group). But they elaborate inhibition of the motor alimentary reaction with difficulty. High stability of the elaborated behaviour (as expressed in the percentage of conditioned reactions after a three-week stressing effect) was exhibited by the animals of the first group, and non-stability by those of the third and second groups. The latter one, occupying a "middle" position was characterized by the highest level of motor restlessness in the avoidance situation, which is regarded as an analog of the alarm property.
对另一个体的叫声做出反应而形成回避封闭空间行为的大鼠（第一组），与那些始终偏好封闭空间的动物（第三组）相比，显著更频繁地进入“旷场”中心，在中度饥饿状态下在新环境中表现出更大的进食活动，并且更易于形成进食反射。但它们很难形成对运动性进食反应的抑制。第一组动物表现出所形成行为的高度稳定性（以三周应激效应后的条件反应百分比表示），而第三组和第二组动物则表现出不稳定性。处于“中间”位置的第二组动物在回避情境中表现出最高水平的运动不安，这被视为类似警觉性的特征。
