The measurement of creativity
The measurement of creativity is still a complex issue. An often used task to measure creativity with is the Alternative Uses Task (AUT). In this task, participants have to come up with as many creative uses for a random daily object such as a brick. In order to score a subject’s creative ability on the AUT there are three frequently used methods: (1) production: the number of given uses, (2) uniqueness: how rare is a given use, and (3) expert ratings of the uses with the “Consensual Assessment Technique” (CAT). With the latter technique, multiple experts rate the degree of creativity for each use on a five-point Likert- scale; the final score of creativity for a use consists of the overall mean of expert ratings. Compared to other ways of rating the level of creativity, CAT ratings are good predictors of creative solutions and are independent of the number of uses. At the same time, interrater reliability of CAT is often low and only sufficient when raters have a high level of expertise.
The Amsterdam Alternative Uses Task (A- AUT)
Funding ABBAS Foundation For Test Development
In 2016 Dr. Claire Stevenson, Dr. Mathijs Baas and Prof. Han van der Maas received funding from the ABBAS Foundation for Test Development to develop a database for the Alternative Uses Task. This database will be used to develop an automatic scoring algorithm and to test the validity and reliability of this algorithm.
With the Amsterdam, Alternative Uses Task (A-AUT) we bring together big-data, psychometric research, and ICT to solve the hereinabove stated problem. The A-AUT is based on the original AUT of Guilford (1950) and will have improved reliability by standardizing and automating CAT scores. AUT-data obtained by different researchers in both the Netherlands and abroad will be collected and stored in one large AUT database. Ratings of creativity are then taken together to obtain the same creativity score for each separate use. Finally, a scoring algorithm will be developed to automatically score uses on their creativity.
