I did not post the other links to dis your post. I just thought some might like to look into it some more. I don't believe that what was represented on that test correlates to spotting a cyclist on the road. The test is not about that cognitive process. It is effective and fun and may make people think (for about a minute), but it is not accurate. How many people that saw this would consciously say to themselves "Hey there might be a cyclist out there today, I will be more vigilant"? How do you will yourself to be more vigilant and sustain it?
Look further if you like.

Visual cognition, perception, attention, and memory. Most of my recent research has focused on the cognitive underpinnings of our experience of a stable and continuous visual world. One line of research focuses on change blindness. These failures to notice large changes to scenes suggest that we are aware of far less of our visual world than we think. Related studies explore what aspects of our environment automatically capture attention and what objects and events go unnoticed. Such studies reveal the surprising extent of inattentional blindness - the failure to notice unusual and salient events in their visual world when attention is otherwise engaged and the events are unexpected. Other active research interests include scene perception, object recognition, visual memory, visual fading, attention, and driving and distraction. Research in my laboratory adopts methods ranging from real-world and video-based approaches to computer-based psychophysical techniques, and it includes basic behavioral measures, eye tracking, simulator studies, and training studies. This diversity of approaches helps establish closer links between basic research on the mechanisms of attention and the real-world implications and consequences of our findings.
