It may be also used in research of the basic speed of the information processing, and operational memory.

Validity

Research confirms the validity of the TSN as a test to evaluate the degree of the automaticity in recalling lexical information and proves that it involves operational memory as well as the ability to process verbal material, and measures the general speed of information processing. In the M version there is a connection found between results and school outcomes, as well as differences in the test between ADHD children and the control group. The results of the S version are connected with the reading progress and differentiate between children with diagnosed dyslexia or its risk, and children without such disorders.
