Dear Ken and Tipsters,
Radiologists "had up to three minutes to freely scroll through each of 5 lung
CTs, searching for modules as we tracked their eyes." They clicked module
locations with a mouse. The gorilla was entered on the final trial.
The naïve observers were given 10 minutes teaching about now to identify
modules then completed the same task as above.
Note that afterwards everyone was asked if they noticed anything unusual when
re-exposed to the gorilla slide. Everyone saw it.
Sincerely,
Stuart

Hi Stuart:
This is a follow-up to Stephen Black's point that the radiologists were looking
for cancer signs and not for other irrelevant images.
What were the instructions that the radiologists and the controls were given?
Ken
