How the results of the tlt are reported

Below are several pictures of how the results of the TLT are shown in a PDF report.


Figure 1: How the stimulus screen looks like. The figure below must be altered and look exactly like the top figure. The blocks are moved by a mouse click or, on a touchscreen, by touching them.


Figure 2: The results of the TLT in a graph. The blue line is the total score for each of the 16 items. The red line indicates the Decision Time, the time that elapses before a block is moved.


Figure 3: The 4 TLT scores compared to the 5 norm groups. The TLTscore is the most important variable.


Figure 4: The results are printed in the report with the manual explaining how the scores should be interpreted.
