[Different anxiety levels in rats selected for their ability to acquire the conditioned reflex of active avoidance]. 1994

D A Zhukov, and E P Vinogradova

Experiments were carried out in rat strains selected for high (KHA) and low (KLA) rates of active avoidance conditioning in a shuttle box. The elevated plus-maze was used for anxiety measurements. Naive KHA rats, as compared with KLA ones, demonstrated much higher anxiety scores. Inescapable electric footshock had opposite effects on anxiety levels in KHA and KLA rats, i.e., it increased anxiety scores in KLA rats and decreased in KHA. The results point to the role of anxiety in adaptive behaviour, e.g., in learning abilities.

D018709	Statistics, Nonparametric	A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data.
