“…However, it may be presumptuous to attribute a change in performance across successive occlusion conditions solely to the specific addition of new information in the display, as the later occlusion conditions not only provide more information but also an extended viewing period and hence a greater overall time in which to process visual information from the unfolding display. It is conceivable that experts and novices may differ in their capability to use, or their dependence on, this extended viewing and processing time (e.g., Adam & Wilberg, 1992;Deary & Mitchell, 1989). Confirmation of the prevailing assumption of active information pick-up from later occlusion conditions is required through demonstration that similar patterns of prediction accuracy improvement, as have been previously observed for instances in which the total viewing period progressively increases from the earlier to the later occlusion conditions, also occur for instances where the total viewing period is kept constant across the different occlusion conditions.…”
