Abstract
This report presents the training records of the children and grandchildren of a pair of rats heavily alcoholized daily for more than two months before the birth of the young. These alcoholized rats came from the same litter; another pair from this same litter was chosen on the basis of equal weight as the parents of the normal controls. All matings were between sibs in the same litter. Habit formation was tested by training on a Watson maze and the Yerkes multiple choice apparatus. The results of the maze training have been calculated on the basis of the last twelve trials of the training proper as well as twelve memory trials given a month later. The criteria used are: average time per trial, number of “perfect” trials, number of wrong turns, or errors. Problems known as “first door to the left” and “first door to the right,” with tests, were used on the multiple choice apparatus; the results are based upon the number of correct first choices, and the number of wrong choices.
It is obvious from the figures in the following tables that the rats that received alcohol and their unalcoholized descendants were less successful than the controls in meeting the situations presented.
