Case 2: The work curve of a person who caused an accident in public transportation

Case 2: The work curve of a person who caused an accident in public transportation

The distinctive feature of this work curve is that the amount of work immediately after the break is extremely low compared with the overall level across the 30 minutes.

People with this kind of curve have a personality and behavioral characteristic of finding it difficult to respond promptly to a situation, which may lead to an accident.

One measure to reduce their accident risk is to carry out thorough checks before starting driving duties.

The Uchida-Kraepelin Test is a psychological test using a work-performance method. Examinees perform single-digit addition for a total of 30 minutes, changing rows every minute, with a 5-minute break between the two halves.

Connecting the final calculation position for each minute produces a graph characteristic of the individual examinee.

The upper graph shows the first 15 minutes; the lower graph shows the second 15 minutes.

The red line is the examinee’s own work curve. In this case, the blue line is the average work curve obtained by averaging test results of contemporary Japanese examinees with a similar amount of work.

Interpreting the red line provides insight into the examinee’s latent behavioral characteristics.


To arrange the Uchida-Kraepelin Test, a work-based aptitude and personality test that can be used in the same way in Japan and overseas, please contact your nearest distributor in your country or region.
