T. G. Wiesel proposed the idea of using short but valid tests based on clear criteria as a quick and reliable tool for detecting neuropsychological disorders in children. This concept is based on the use of concise test batteries designed according to precise scientific principles, standardized for a wide sample of children, taking into account age and cultural differences. These tests are short and easy to administer, making them suitable for use in schools and health centres. Despite their brevity, they are able to identify accurate indicators of impairment of functions such as memory, attention, perception and speech. A distinctive feature of this model is a combination of speed and accuracy, as the neuropsychologist obtains quantitative data that is comparable to standards, which increases confidence in the initial results and determines the need for in-depth evaluation in the future. This approach contributes to the wider use of neuropsychological diagnostics in educational and medical institutions.
