In a Program Evaluation and Review Technique (PERT) network, no process can begin executing until all processes that immediately precede it have completed their activity. PERT networks have been used in psychology to investigate the structure of cognitive processes, and may be applied also to the analysis of eye-movements in order to gather detailed information on the processes underlying the ocular activity. This may be particularly useful to understand phenomena for which specific hypothesis have been made. The primary aim of this paper is to show the potential of this approach as a visualization technique, and to devise a research agenda for future applications of PERT networks as a method for investigating the time course of visual scanning.
