Jegi—Auditory Memory Spun for Numbers . 513 
5. Tlie actual memory span by grades is as follows: 
5.2 for the first grade. 
6.1 for the second grade. 
6.5 for the third grade. 
6.2 for the fourth grade. 
7.0 for the fifth grade. 
7.3 for the sixth grade. 
7.5 for the seventh grade. 
7.9 for the eighth grade. 
6. This test has to do only with mechanical memory and not 
with rational, logical, or assooiational memory; with native, 
crude, inherited power and not with skill resulting from school 
training or previous acquirements; with power or capacity as 
such and not with knowledge or facts the resultants of individ¬ 
ual experience. 
7. In this study and in all similar investigations it is quite 
impossible to abstract attention from native capacity to retain 
and recall, and hence we must make an allowance for or take 
into account the child’s increase in power of close attention ; and 
it may be that the increase in memory power is little more than 
ability to hold the mind more and more closely to the work to 
be done; if this view be accepted then we are testing native mem¬ 
ory power as colored by the gain in attention from age to age 
and from grade to grade.
