"During this rest of this examination don't turn any page forward or backward unless you are told to. Now turn 

 over the page to test 2." 



Test 2, memory span. 



N. B. Examiner. Read the numbers (next page) in this test very distinctly at the rate of 1 digit per second, 

 taking special care to avoid grouping or accenting. Allow not over 10 seconds for writing 4, 5, and 6 digit numbers. 

 Allow not over 15 seconds for writing 7, 8, and 9 digit numbers. Proceed with the numbers of form A (or B, etc.) 

 giving the two 3-digit numbers, the two 4-digit numbers, the two 5-digit numbers, and so on through the two 9-digit 

 numbers. Announce before each set the number of digits and the number of the set. Thus, begin by saying: 



"Attention! Look at the directions while I read them. ' This is a test to see how many figures you can remember 

 and write down after they are spoken. In the first row of empty squares write the first set of figures you hear, as shown 

 in the samples; in the second row write the second set you hear, and so on.' 



"In this test I shall not say 'Go,' but you are to keep your pencils raised until after I have read the whole set of 

 figures." 



"Attention!" (Hold up the hand as an example.) " Keep pencils up until I am through reading. Three figures, 

 first set, 1 3 5." (Drop hand. Allow not over 10 seconds.) 



"Attention!" (Be sure that every pencil is up.) "Three figures, second set, 6 4 1." (Drop hand. Allow not 

 over 10 seconds.) 



"Attention! Four figures, first set," and so on. (Be sure to begin in the correct column.) 



"Turn over the page to test 3."
