Mentimeter No. 11
MEMORY FOR NUMBERS
Character of the Test.
This test is planned as an individual examination to be given to any candidate who understands the English language. The test is borrowed directly from the Binet series and was used as a group test in the first form of the Alpha examination in the United States Army.
The usefulness of this test is probably limited to the selection of candidates for very simple mechanical operations and to the classification of pupils in the schoolroom. It might be employed as one of a series of tests in the selection of telephone operators, but its use in such a case is probably more obvious than practical.
Directions for Giving the Test.
The candidate should be seated comfortably in a quiet place and should be instructed to listen carefully. The examiner should fill out the blanks at the top of the title page, recording only such facts as seem to be necessary. The examiner should then repeat the following formula:
“I am going to read to you sixteen series of numbers. The first series will be very short and the last series will be quite long. When I have read a series I want you to repeat all of the numbers it contained. I shall read them slowly so that you can be sure to get them. Listen very carefully and try not to forget any number. Do not repeat any number until I have finished the whole series and stopped speaking.”
The examiner should announce each time just how many numbers will appear in the series. The digits should be read at the rate of one per second, taking care to avoid any rhythmic grouping of the numbers. The examiner should look up expectantly as soon as he has finished reading a series. No intimation should be given a candidate as to whether or not he is being successful. The first series should be read as follows:
“The First Series contains two numbers which are, 5, 6.” As soon as the candidate has repeated these numbers the examiner should say:
“The Second Series contains two numbers which are, 2, 7.”
