Relationship between choice reaction time and the Tower of Hanoi test

The aim of this study was to examine a possible relation between the speed of information processing, as measured by simple and choice visual RT, and problem-solving, as measured by the Tower of Hanoi test. For 20 normal teen agers, performing all tests, significant correlations were found between ch oice RT and both measures of performance on the Tower of Hanoi, number of d isk moves, and time taken to complete the task. Simple RT was correlated wi th Completion time but not with the number of moves, while the reverse patt ern was discerned for decision time. Choice movement time was also associat ed with both measures, but simple movement time was not. These results are consistent with the hypothesis of a common neurobiological basis to informa tion-processing speed and executive functions.
