DYNAMIS Software (english)

Comment from the year 2012: The DYNAMIS software (described below) is outdated. But don't worry! We have successors for that instrument that are much better.

First, there are our new paradigms, called MicroDYN and MicroFIN. The "Micro" stands for the idea of using minimal complex systems for psychometric reasons. The "DYN" stands for DYNAMIS, i.e. linear structural equation approch, whereas "FIN" stands for finite state approach.

You can find more info about this here (the PDFs can be downloaded for free from Joachim Funkes publication list):

Second, there is a wonderful cross-platform software called K.R.A.F.T. from Andreas Fischert hat does all the things that the old DYNAMIS software did (and even more than that!). Go on his page and you can download it.

For historical reasons, the old German explanation about DYNAMIS will be left online for documentation.

DYNAMIS-Software (Excerpt from the README-File of the old DOS-version)

DYNAMIS is a general-purpose PC-software which allows to construct arbitrary dynamic systems. These systems follow the principles of linear structural equation systems. Task of the subjects is normally two-folded: first, to identify the hidden structure which does exist between exogenous and endogenous variables; second, to control the dynamic system with respect to some goal values.

The logic behind the construction of such systems is described in the following papers:
Funke, J. (1991). Solving complex problems: Human identification and control of complex systems. In R.J. Sternberg & P.A. Frensch (Eds.), Complex problem solving: Principles and mechanisms (pp. 185-222). Hillsdale, NJ: Lawrence Erlbaum.

Funke, J. (1993). Microworlds based on linear equation systems: A new approach to complex problem solving and experimental results. In G. Strube & K.-F. Wender (Eds.), The cognitive psychology of knowledge (pp. 313-330). Amsterdam: Elsevier Science Publishers.

Funke, J. (1995). Experimental research on complex problem solving. In P.A. Frensch & J. Funke (Eds.), Complex problem solving: The European Perspective (pp. 243-268). Hillsdale, NJ: Lawrence Erlbaum Associates.

The simulation program DYNAMIS exists on a fileserver together with a lot of parameter files (compressed into a ZIP-File [240 KB] for PC's). With these parameter files, different dynamic systems can be created which all follow the same structure imposed by DYNAMIS.

If you click   here, the FTP-Server will be activated and the ZIP-File will be downloaded to your disk.

How parameter files are constructed can be found in the following report which contains also most of the parameter files:

Funke, J., Fahnenbruck, G. & Müller, H. (1986). DYNAMIS - Ein Computerprogramm zur Simulation dynamischer Systeme. Berichte aus dem Psychologischen Institut der Universität Bonn 12, Heft 3. (ISSN 0931-024X)

This report is partly published on this WWW-server (click here).

Please note that program and especially the source code is free for use only for scientific purposes. If you got the source code from us please do not distribute it further without asking us. If you want to use DYNAMIS for commercial applications please send a letter or email to Dr. Joachim Funke to set up the appropriate conditions of use.

You start the program by simply typing 'DYNAMIS'. Then you have to input the name of the parameter file.

Changes on parameter files as well as the construction of new ones are easily done by means of the program DYNCONST (Thanks to "Jean-Paul Reeff"!). Using DYNCONST allows you to easily change all parameters in a simple way. Note: if you construct a parameter file by your own (i.e., using a normal text editor) you must give the extension '.PRM' to that file.

You are encouraged to report results of your DYNAMIS experiences, positive as well as negative ones. Also, I am very interested to hear about publications involving DYNAMIS software.

General Background

The background for the construction of linear structural equation systems, the logic of research behind these systems, and the results of experimental work is described in more detail in the following text:

Funke, J. (1992). Wissen über dynamische Systeme [Knowledge about dynamic systems]. Berlin: Springer (Lehr- und Forschungstexte Psychologie). [ISBN 3-540-55223-5] <

Overview over existing parameter files

Experiment from Funke (1985, Zeitschrift für Psychologie, 193, 443-465; cf. Fritz & Funke, 1988, Zeitschrift für Psychologie, 196, 171-187); the parameters x and y in the parameter file represent x = degree of autoregressive processes (1 or 2), y = degree of connectivity (1=small, 2=medium, 3=large).

Unpublished experiment from Funke (1985); comparison of numerical and grafical presentation of the same system.

Parameters follow the system from Funke (1981, Trierer Psychol. Bericht, 8, Heft 9).

Parameters follow the system from Gediga, Schöttke & Tücke (1983, Bericht aus dem Psychol. Institut der Univ. Osnabrück).

Parameters follow the system from Broadbent (1977, Quarterly Journal of Experimental Psychology, 29, 181-201).

Illustration of the Peter-Prinzicle (parameter settings according to Klaus Opwis, 1985, Diss. Freiburg); recommended: hire only people without qualification!

System with suppressor variables from Funke (1986, unpublished): only 3 variables, but enormous difficulty in identification task. Try to manipulate with 'Werbung' the 'Umsatz' variable (bring it to 300 - and keep it there!) ...

Simulation of the system from Berry & Broadbent (1987, Psychological Research, 49, 7-15). On "Friendliness" you should use only integers (range 1-12)!

Simluation of a strange planet whose structure has to be identified (see Funke & Müller, Sprache & Kognition, 7, 1988, 176-186).

Simulation on the recycling of spoiled oil (see Fahnenbruck, Funke & Rasche, 1988, Bonner Berichte, Band 14, Heft 2).

Recent Publications involving DYNAMIS

From the Bayreuth team DYNAMIS-versions called LINAS, LINAS-! and LINAS-2 have been developed and used in research:

Preußler, W. (1997). Effekte des Kontexts auf den Wissenserwerb bei der Steuerung eines dynamischen Systems. Sprache & Kognition, 16, 48-59.

Another DYNAMIS-system called BIOLOGY LAB can be found in:
