The subjects are told to study the materials^ so as to be able to reproduce 

 the correct words under their respective numbers. A hundred subjects, 

 tested individually, were told to study until they were sure they could 

 give perfect reproduction. Their times for learning and for recall were 

 kept. They were surprised by a request for a second recall after three 

 weeks. Five minutes for learning and three minutes for recall were al- 

 lowed 278 public-school children tested. They were surprised by a second 

 recall after one day and a third recall five weeks later. 



Partial results of the latter group only were presented. The average 

 percentage of the correct words and figures that are recalled in correct 

 order is used to measure the amount of absence of confusion. By the 159 

 boys and girls of the high school the average per cent, for words in im- 

 mediate recall is 71.3 and after one day 60.9. For figures the percentages 

 are 74.4 and 70.4. By the eighth grade the records are : AVords, 78.8 and 

 62.9; figures, 73.8 and 51.5. Seventh grade: AYords, 56.1 and 39.7: fig- 

 ures, 53.3 and 27.4. Sixth grade: Words, 60.0 and 43.7: figures, 61.9 

 and 49.6. This shows confusion in the first recall and a very pronounced 

 increase in confusion after one day. 



The Section then adjourned.
