Test "Calculations by Kraepelin" - online version

The test "Calculations according to Kraepelin" was proposed by the German psychiatrist Emil Kraepelin and is intended to study fatigue, exerciseability and volitional efforts of a person (initially, the technique was created to assess the abilities of patients, but later began to be used for any people). Nowadays, the methodology is used to determine fluctuations in attention, switching and the study of mental tempo.

The essence of the technique is that the subject needs to sequentially add the pairs of numbers presented in the table in ten rows, located one above the other, and enter the result of the addition under these numbers, but discarding ten - if the resulting number turns out to be more than ten. That is, if during the addition you got 17, then the result should be entered only 7. If during the addition you get a number equal to ten, then you need to write down 0 (zero). Estimated completion time up to 4 minutes. The test is best done on devices with hight screen resolutions!

Kraepelin Calculation Test, theory

Below is a picture of what the test looks like on this site. Under each pair of numbers in a row of a table of two rows of numbers, there is a window for entering the result. It is desirable that you have the keyboard in plain sight, which will make it easier to enter the result.

The result is determined visually by the number of correct answers at the beginning and at the end of the table, that is, if the number of correct answers decreases from line to line, this may indicate a high level of fatigue. An increase in the number of errors can also speak of this. Below is a table of results that you will see after passing the test.

Correct answers are marked in yellow in the table, errors in red. It turns out a yellow column of a certain size, consisting of correct answers. On the right, you can see the number of errors and the number of correct answers. The fewer answers, the correspondingly lower the pace of work, the more answers, the greater the pace of work.
