Visual Attention and Representation Switching During Java Program Debugging: A Study Using the Restricted Focus Viewer
TLDR
The aim of this investigation was to address questions such as 'To what extent do programmers use each type of representation?' and 'Are particular patterns of representational use associated with superior debugging performance?'.A modified version of the Restricted Focus Viewer was employed to measure the degree to which each of the representations was used, and to record switches between representations.
