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.
