d2-R, a revised version of the attention and concentration test is already available!

2020-10-26

A new tool designed to examine drivers and candidates for jobs which are difficult, dangerous or require more attention and concentration is now on our offer – this is d2-R, a revised version of the attention and concentration test. The examinee task is to cross out within a limited period of time particular symbols from among the group of similar symbols presented to him/her. The test scores provide indices which allow to assess ability to concentrate as well as speed and accuracy of work performance. The new version includes an exercise sheet, a self-copying sheet for performance assessment, an enlarged number of characters in each line as well as simplified score calculation.

The Polish version was standardized with the sample of adults aged 20–79.
