Concepts

In spite of the popularity and widespread use of disc-transfer tasks like the Tower of London and the Tower of Hanoi, only very few studies addressed in detail the impact of structural problem parameters on measuring the cognitive processes underlying ‘planning’. We therefore developed TowerTool which integrates several concepts of the structural determinants of problem difficulty into a comprehensive and easy-to-use software package and allows for systematic analyses of the problem space and individual problems of disc-transfer tasks.

Software and Download

TowerTool is an open-source software solution written in MATLAB that allows easy access to in-depth analyses of problem structures of widely used planning tasks like the Tower of London, the Tower of Hanoi and their variants.

The current version of TowerTool and a comprehensive manual can be downloaded free of charge at the following URL ftp.uniklinik-freiburg.de (user: tower pwd: tower). TowerTool is distributed under the GNU General Public License (Version 3). By accessing the above ftp-server for downloading TowerTool, you agree to abide by the terms and conditions of that license.

Implementation

In close cooperation with the Schuhfried company, we have developed the Tower of London - Freiburg Version (TOL-F) as a computerized test for the assessment of planning ability. Most importantly, we have incorporated current knowledge about the impact of structural problem parameters on planning impairments so as to provide a reliable and valid foundation for diagnostic decisions in clinical practice. The TOL-F is implemented in the Vienna Test System (VTS) and is described there.
