Dear TIPSTERS,
I held back on this until I had some facts.
The immediate question that came to mind was "If 83% of radiologists did not
see the gorilla, what was the rate for non-radiologists?"
That is, was there a control group.
Dr. Drew has kindly supplied me with a preprint of his manuscript and here are
the facts:
Of 24 radiologists, 20 failed to detect the gorilla.
Of 24 non-radiologists, 24 failed to detect the gorilla.
Now that puts a different spin on what I have heard all over the media.
Sincerely,
Stuart

Subject: Re: [tips] Inattention blindness in radiologists
Hi
Interesting study, although I wonder what it says about radiology examinations.
If part of the lung was covered by an ape, then it was impossible for the
radiologist to determine that the tissue in that region was not contaminated,
assuming that inattention blindness does not mean that viewers see through the
ape. Does that mean that radiologists look only for symptomatic objects in the
images, rather than determining that all parts of the image are actually clear?
And what would happen then if there were "imperfections" in radiology images
such that the health of the region was indeterminable? Or does that never
happen? The cited study certainly suggests that radiologists cannot identify
even gross imperfections (the ape) in the images, unless there are certain
types of imperfections that are indeed caught.
In the original studies, has anyone ever determined whether the counts of
passes were off systematically because of passes hidden by the ape-suit
character in the middle of the scene?
Take care
Jim

It was good timing for me. I showed the original in the cognitive class last
week. When I heard the story I sent the NPR link to the class. I think it is
good to be able to show how a rather goofy study about attention can actually
have real applications.
