Throughout test<br />
We also logged errors committed by the participants with the intention of analyzing this data<br />
quantitatively. However, errors significantly differed from each other in quality and severity, and we<br />
did not have a well-defined definition of errors at the beginning of the test. Therefore, we decided not<br />
to include the error count in our analysis. Instead, comments about errors appear in the qualitative<br />
sections of our results.<br />
