For software development practitioners, this paper is not an easy read. The terms are couched in the formal language of research on skills and practices. While the main focus is on the software review process, the paper also focuses on categorizing the impact of personal qualities on the quality of the task. The main issues are: training in the review process; general software development experience; and experience performing reviews.

This type of research is common in cognitive psychology. The research challenge is to identify the primary factors that impact the quality of the end product. Unfortunately, it is difficult to perform these studies in software development, and this paper is a good example of the pitfalls. The study population consists of 192 students who are studying for their first degree in information systems. The task was to review a design document. It may be interesting to understand the behavior of unskilled individuals on generic tasks, but this is far from a real-world experience. As a manager, I would not expect undergraduates to be primary contributors to a software review process.

If you really like cognitive research, read this paper. It is a very reasonable, representative, professional study. But for most practitioners, this paper is just too weak to be of any help.
