The purpose of this live study is to investigate the impact of emotional states on the efficiency of correcting defects within a Conceptual Model verification context. We plan to use the CoSTest tool for verifying defects and measure the experimented emotions during the testing tasks through I-PANAS-SF and SUDS instruments. Furthermore, the design, overview and potential threats of this experiment are presented.
