Age changes in typological properties of the nervous system were studied with alimentary and defensive reinforcements in 55 dogs: from one to two months old, three to four and twelve months old. Of these, 26 were annually examined up to the age of two to four years. The degree of similarity of each typological property, with both kinds of reinforcement, was determined in one and the same animal. The presence or absence of partiality was estimated for each typological property of the nervous system. In all the one to four months old puppies the excitatory process was estimated by both methods as strong or medium; without partiality. By the age of one to two years the partiality increases due to enhanced excitation in the defensive system. Partiality of the nervous processes equilibration is observed already in one to four months old puppies, though decreasing with age. Partiality of nervous processes mobility becomes more pronounced with age.
在55只犬中，研究了神经系统类型特性随年龄的变化，这些犬的年龄从1至2个月、3至4个月到12个月不等。其中26只犬每年接受检查，直至2至4岁。在同一只动物身上确定了每种类型特性在两种强化方式下的相似程度。评估了神经系统每种类型特性是否存在偏向性。在所有1至4个月大的幼犬中，两种方法评估的兴奋过程均为强或中等；无偏向性。到1至2岁时，由于防御系统中兴奋增强，偏向性增加。神经过程平衡的偏向性在1至4个月大的幼犬中就已出现，不过随年龄增长而降低。神经过程灵活性的偏向性随年龄增长变得更加明显。
