Kraepelin Test

Kraepelin Test: A Brief History 

Developed by a psychiatrist named Kraepelin, it was first meant to tell the difference between normal and abnormal people. But this test is also used by the military and companies to choose who gets to be in charge and what their roles are. 

Dr. J. de Zeeuw says that Kraepelin tests are tests that measure things that aren't intellectual (concentration tests). 
Anne Anastasi, who wrote a book called "Psychological Testing," says that the Kraepelin test is a "Speed Test." The test is that you don't have enough time to answer all of the questions. So, the Kraepelin test doesn't expect the testee to finish each path. Here, you can see how the speed of testee works. 

In addition to the speed of work, other factors that are shown are accuracy, concentration, and stability in work. There are many psychological factors that play a role, such as vision, sense-motor coordination, pushing power, resilience, and the effect of learning. 

Most people don't know about Kraepelin's way of classifying schizophrenia and manic depression. His work, which lacks Freud's literary brilliance and paradigmatic importance, is rarely read outside of academic circles. Most people don't know about Kraepelin's way of classifying schizophrenia and manic depression. His work, which lacks Freud's literary brilliance and paradigmatic importance, is rarely read outside of academic circles. During the time when Freudian etiological theories were popular, Kraepelin's ideas were also ignored. His ideas rule psychiatric research and the academic world. 

His ideas about how to diagnose psychiatric disorders are still used today. For example, the American Psychiatric Association's DSM-IV and the World Health Organization's ICD systems are based on the Research Diagnostic Criteria and the earlier Feighner Criteria, which were made by "neo-Kraepelinians." However, Robert Spitzer and other members of the DSM committees were careful not to make assumptions about causes like Kraepelin did. 

Kraepelin designed a large-scale, clinically-oriented epidemiological research program. He got information about the clinical situation from a number of places and networks. Even though he said that he used strict clinical standards to get information "by professionally studying individual cases," he relied on what non-psychiatric officials said. His textbooks don't have long case histories. Instead, they have a mosaic of typical things that patients say and do. People have said he is a bourgeois or a reactionary. 

Because Kraepelin's writing is short and easy to understand, doctors can learn a lot from it. Allan Ross Diefendorf (1871–1943), an assistant physician at the Connecticut Hospital for the Insane in Middletown, translated the sixth and seventh editions of his textbook into English in 1902 and 1907.

These translations were short and awkward, and they didn't show how brilliant his writing was. 

At the beginning of the 20th century, Alois Alzheimer and Emil Kraepelin taught Nicolás Achcarro and Gonzalo Rodrguez Lafora in Munich. These two men were part of the Spanish Neurological School.

Kraepelin Test Procedure 

The Kraepelin test is made up of 45 rows of unit digits from 0 to 9, with up to 60 numbers randomly placed in each column. 
The person being tested has to add up two numbers in a short amount of time, starting with the lowest number in each row.

Kreapelin test as a personality test

The Kraepelin test can be used to figure out what kind of performer someone is. For instance, 
1. The result of adding up a bunch of very low numbers can show signs of depression. 
2. Making too many mistakes in math can be a sign that your mind is wandering. 
3. A sudden drop in the graph could mean that the person has epilepsy or is temporarily forgetting things during the test. 
4. A rhythm or graph with a big difference between the highest and lowest points could be a sign of an emotional problem. 

Kreapelin Test as an Approach Test 

As an aptitude test, the Kraepelin test was meant to measure how well someone could do at their best. So, there should be more pressure on scoring and interpreting test results in an objective, not a subjective, way.

Based on the results of objective calculations, four things can be said: 
1. How fast do you travel?
2. Accuracy factor
3. Rhythmic factor
4. the ausdeur factor

Guilford (1959) says that the total number of items in number form From the point of view of how the mind works, this unit is an example of convergent thinking. But if you look at what's in the item, you can tell that it's about numerical facility, which is the ability to use numbers quickly and completely. 
Freeman (1962) says that sensory perception and motor response factors have a big effect on how this test turns out. 

According to Thrustone (in Anastasi, 1968), the items on the Kraepelin test measure one of the most important mental skills: the number factor. This is the ability to do simple math calculations correctly and quickly.


1. A Kraepelin test question sheet is needed. This test has 45 lines of numbers, but most of the time, only 40 lines of numbers are used. 
2. a chronometer 
3. Pencil (it's recommended to have a spare) 
4. The table is wide enough for the test subject to be able to open the folded Kraepelin test sheet and chair. 
5. Use a blackboard and chalk or a flipchart to explain how to take the test.
