Article published in the Journal of Consumer Psychology
Together with Prof. Keith Wilcox, Ph.D. from Columbia University, USA, Dr. Sören Köcher has published an article titled "I Made It Work: How Using a Self-Assembled Product Increases Task Performance" in the Journal of Consumer Psychology. In three experiments, the two researchers demonstrated that consumers performed better on tasks with products that they had assembled themselves in advance than with ready-made products. The authors show that this effect results from an increase in self-efficacy among the test subjects.
