Search for a distressed swimmer in a dynamic, real-world environment.

What is it about?

This study used real video clips of swimmers in difficulty to explore lifeguard visual search using traditional reaction-time studies and a novel occlusion method. The results suggest that lifeguards have better detection of distressed swimmers compared to non-lifeguards, however this was not reflected in overall eye-movements measures. This research also shows support for an occlusion method for distinguishing between different groups visual processing in dynamic scenes for the detection of domain specific targets.
