This appendix reproduces examples of transcripts of mental model interviews from our first mental model study, which was of radon. The guidelines offered in Chapter 4 reflect our experiences in this and later studies and were not all followed completely in this first study. In these transcripts, you can see where the interviewer has completed the first-phase follow-ups and gone on to more specific questions. You may wish to copy the interviewer worksheet reproduced in Figure 4.1 and try using it to keep track of the topics covered in these examples. Note that one of the interviewees asks the interviewer a question designed to obtain information, but the interviewer defers the answer.
