notation and variety, though to a less degree than the adjectives. 

 Owing to the dearth of words in his vocabulary a good many 

 words of common knowledge were unknown to him and their 

 reactions had to be recorded as failures. These reasons may 

 account for the break in the results. For this subject as well 

 as for all the others the reaction times for the rejected words 

 of this practise series are much longer than for the selected words 

 of the regular series. 



TABLE 9 



Reaction times for practise adjectives and nouns, preliminary three days' practise 



(totals) 



Table 10. This table shows the results by days for the prac- 

 tise period. There is only one case where the noun series gave a 

 shorter reaction time than the adjective series. There are six 

 exceptions however to the rule for syllable variation, three for 

 adjectives and three for nouns. 



Tables 11 to 14 (inclusive). These give respectively the dis- 

 tribution of reaction times for each of the eight subjects for the 

 regular ten days' work, with the average reaction time, mean 

 variation, and the total number of cases given at the foot of 

 each column. It is to be noted that the difference between the 

 actual number of cases recorded and the number of stimulus 

 words given in each group (180 or 360) is due to various causes: 



1. Failure to respond at all, or with a suitable word. 



2. Stopping of the motor.
