Towers of Hanoi and London on a tablet-PC: correlations with other executive tests

We have developed computerised versions on a tablet PC for the popular executive function tests Tower of Hanoi (ToH) and Tower of London (ToL) (Hinz et al., 2007). They simulate the original wooden games in a realistic manner so they can be used at the bedside. In addition to timing each step, the program documents the solution pathway chosen and visualises it in a state graph. We analysed the two tower puzzles for possible performance differences and compared them with other executive function tests. 62 controls (44 female) from two age groups (20–45 years, mean 29.1; 46–70 years, mean 57.8) had to solve 20 tas…
