Design outcomes

Primary

MeasureTime frame
The aim of the study is to determine whether an OLP can improve divergent thinking. In this context, the AUT (“Alternative Uses Tasks”) is used to assess the following two facets of divergent thinking: Fluency and Originality.

Secondary

MeasureTime frame
In the course of explorative analyses, correlations between the participants' expectations regarding the OLP's effectiveness and the actual changes in divergent thinking are recorded. In addition, it will also be determined whether the suggested improvements in creativity / mood actually led to noticible changes. For this purpose, the participants are given scaling questions.
