Why even radiologists can miss a gorilla hiding in plain sight?

This is because when you ask someone to perform a challenging task, without realizing it, their attention narrows and blocks out other things. So, often, they literally can’t see even a huge, hairy gorilla that appears directly in front of them.

Can a radiologist miss a tumor?

A radiologist could improperly administer and interpret a mammogram, which could result in a missed or delayed diagnosis of breast cancer. A radiologist reading a chest X-ray could miss a tumor. This could cause a critical delay in a patient’s diagnosis of lung cancer.

What is the gorilla experiment?

The phrase, “the invisible gorilla,” comes from an experiment created 10 years ago to test selective attention. In it, study participants are asked to watch a video in which two teams, one in black shirts and one in white shirts, are passing a ball.

Does a gorilla have lungs?

The right lung of the gorilla consists of the upper, middle, lower, and accessory lobes. The right lung has the dorsal, lateral, and ventral bronchiole systems, but the medial bronchiole system is lacking. The upper lobe is formed by the first branch of the dorsal bronchiole system.

Can a radiologist miss a gorilla in a lung scan?

Notice anything unusual about this lung scan? Harvard researchers found that 83 percent of radiologists didn’t notice the gorilla in the top right portion of this image. This story begins with a group of people who are expert at looking: the professional searchers known as radiologists.

How big is the gorilla on a CT scan?

Radiologists were asked to look at five lung CT scans, each which contained about 10 nodules or abnormalities. They were asked to click on anything strange on the scans. On the final scan, a gorilla about 48 times the size of an average nodule was placed in the upper right hand quadrant.

Why are so many radiologists missing dancing gorillas?

Dr Drew suggests that more of them might have detected an albino gorilla or, counter-intuitively, a smaller gorilla, closer to the size of the target nodules. And it is not just gorillas.

How big is a gorilla compared to a lung nodule?

We asked 24 radiologists to perform a familiar lung-nodule detection task. A gorilla, 48 times the size of the average nodule, was inserted in the last case that was presented. Eighty-three percent of the radiologists did not see the gorilla. Eye tracking revealed that the majority of those who missed the gorilla looked directly at its location.
