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.” First Series 5 6 Second 〃 2 7 Third 〃 9 3 5 Fourth 〃 4 1 6 Fifth 〃 7 4 9 3 Sixth 〃 4 8 5 7 Seventh 〃 9 5 7 3 8 Eighth 〃 6 8 1 2 4 Ninth Series 2 6 8 3 5 9 Tenth 〃 6 3 5 9 2 7 Eleventh 〃 9 5 8 3 6 2 4 Twelfth 〃 8 1 9 5 2 6 3 Thirteenth 〃 3 5 2 6 8 3 4 9 Fourteenth 〃 2 8 5 9 3 6 1 4 Fifteenth 〃 6 3 9 4 8 1 7 2 5 Sixteenth 〃 7 1 4 9 6 3 5 2 8 _Directions for Scoring the Test._ The examiner should keep on the test leaflet, out of the sight of the candidate, a notation of exactly which series cause failure. Misplacement of any digit in the series should count as an error and bring no credit for that series. The total score obtained by counting the number of series in which each number was correctly repeated in its right order should be written in the lower right-hand corner of the title page of the leaflet. Scores from 0 to 7 indicate Inferior Ability Scores from 8 to 9 indicate Low Average Ability Scores from 10 to 12 indicate Average Ability Scores from 13 to 14 indicate High Average Ability Scores from 15 to 16 indicate Superior Ability MENTIMETER NO. 12 REPEATING NUMBERS BACKWARD _Character of the Test._
