Typological features in the behavior of rats

The existence of internal relationships between measures of investigative and seeking types of activity and the level of anxiety was demonstrated in rats. Individual measures of investigative activity and levels of anxiety were measured using classical methods-the open field test and the elevated plus maze test. The productivity of directed seeking activity was studied using methods developed by ourselves in a universal problem-solving box. Cluster analysis demonstrated hierarchical groups in the population with similar quantitative-qualitative behavioral characteristics.
