Abstract
Rats from the strain Wistar/WU/Ivanovas were trained to jump over a hurdle to avoid an electric shock. Learning experiments performed on rats selected for good (GL) and bad (BL) learning, (plus unselected control groups), yielded the following results:
-
1.
F7 – F14 BL no longer react to the selection bias and the corresponding GL react only very feebly.
-
2.
In comparison with the F1 and F2 generations of GL and BL the variability decreases. The animals become less sensitive to exogenous factors.
-
3.
Details are given on exogenous (and endogenous) factors with or without influence on the learning results.
