RECORDS OF MEETINGS 259 



The successive association under single class names may be called less 

 controlled, the other more controlled associates. In the 3 minutes the 

 average total number of words given for group I as less controlled asso- 

 ciated is 56.4, M. V. 5.8, with a range of from 34-80 words. For more 

 controlled associates the respective figures are 46.1, 4.9 and 20-60. For 

 group II the less controlled associates give 60.4, M. V. 6.5, and a range 

 of from 39-77 words; the more controlled 42.5, 4.0 and 32-58 respectively. 

 This test is unfair to the less controlled records because of time lost in 

 writing. 



In a second experiment on 56 more girls the subjects were divided into 

 pairs, each member of the pair serving as subject and experimenter in 

 turn. 



The writer read 20 class names pausing 8 seconds for each name while 

 one of each pair named as many individuals of that class as possible. 

 Number two recorded the number of individual names given. Then 

 number one was provided with a list of these 20 class names and on 

 signal she named an individual of each class name, repeating the opera- 

 tion until interrupted by writer at the end of 2 min. 40 sec. ISTumber 

 two recorded the number of responses as before. Then number two pro- 

 ceeded in reverse order with number one as recorder. 



In the 2 min. 40 sec. the average total number of individual names 

 given is for less controlled associates 123.7 M. V. 13.8, range 89-182; 

 more controlled associates 66.9, M. V. 9.7 and 53-106. Four subjects 

 studied practice effect by repeating the test 9 times, over a period of 

 several days. Three found an increase in the total number of associates 

 of each ij^Q and the superiority of the less controlled associates increased 

 with time. For the other subject both decreased with time. 



These facts emphasize a fundamental difference between the two 

 types of associates and the rather obvious inference tliat classification is 

 a very natural process. The study is still in progress. 



Miss Mulhall stated that an attempt was made to determine whether 

 or not there are any characteristic differences between the two memory 

 processes known as recall or reproduction and recognition. Answers 

 were sought to the five following questions : 1 — Does the person who 

 recalls one kind of material well also recall another kind of material well ; 

 or what is the correlation between the recall of different materials ? 2 — 

 Does the person who recognizes one material well also recognize another 

 kind as well; or what is the correlation between the recognition of dif- 

 ferent materials? 3 — Does the person who recalls one material well 

 recognize that material well ; or what is the correlation between the
