We focus on their developed and deficient cognitive functions, their fulfilment of complex tasks, a preferred modality in which the tasks are presented, and differences between the results obtained through static and dynamic testing. The results collected from individual subjects are finally compared and visualized using figures and graphs which gives an overview of the studied phenomena throughout the whole research sample. We found all the clients of the research sample having following...
