Ontogeny and interdependence of genetically selected avoidance and open-field behaviors were investigated in six genetic lines, involving 1,018 animals, and three developmental models (longitudinal, cross sectional, and generational). In selected lines, behaviors varied with age, depending upon the genetic selection; in the control (random bred) line, no such effects were found. Between the lines selected for high (RHA) and low (RLA) rates of two-way-active avoidance, ontogenetic differences in the selected behavior emerged as the animals grew older, whereas between the lines selected for high (MR) and low (MNR) frequency of open-field defecation, the differences in the selected behavior were present at all stages of development. In unconditioned escape response to footshock, which shows an inverse relation to avoidance response in the RHA and RLA lines, and in general activity (number of sections crossed in an open field), which shows inverse relation to defecation in the MNR and MR lines, the differences were present at all stages. The relation between avoidance response and open-field defecation (emotional reactivity) was not linear but suggestive of curvilinear inverted-U-function.
在六个遗传品系（涉及1018只动物）以及三种发育模型（纵向、横断面和世代模型）中，研究了基因选择的回避行为和旷场行为的个体发育及相互依存关系。在选择品系中，行为随年龄变化，这取决于基因选择；而在对照（随机繁殖）品系中，未发现此类效应。在双向主动回避率高（RHA）和低（RLA）的选择品系之间，随着动物年龄增长，所选行为出现个体发育差异；而在旷场排便频率高（MR）和低（MNR）的选择品系之间，所选行为的差异在发育的所有阶段都存在。在对电击的非条件逃避反应中（在RHA和RLA品系中与回避反应呈反比）以及在一般活动（在旷场中穿过的区域数）中（在MNR和MR品系中与排便呈反比），差异在所有阶段都存在。回避反应与旷场排便（情绪反应性）之间的关系不是线性的，而是呈曲线倒U形函数。
