What can a person in a gorilla costume teach us about our ability to pay attention?
Subject: Attention - Inattentional and Change Blindness - The Invisible Gorilla
Event: Birthday of psychologist Christopher F. Chabris, 1966
What we get from each moment depends on the attention we give it, and the quality of our experience reflects the quality of our awareness. -Roger N. Walsh
Today is the birthday of psychologist Christopher F. Chabris, a man whose research has helped us to better understand how we see the world, and just as important, how much we do not see.
Although many of us believe that we see everything that’s in front of us, Chabris’ work reveals that our vision is much more narrow than we think it is. This is what Chabris calls inattentional blindness.
Inattentional blindness is best illustrated by Chabris’ famous invisible gorilla experiment. Participants were asked to watch a video of people passing a basketball. Some of the people in the video wore a black shirt, others a white shirt. Participants were asked to keep track of how many times the people in the white shirt passed the basketball. What the subjects were not told is that halfway through the video a person dressed in a gorilla costume would walk through the scene, stop, pound his chest, and walk out of the picture. After watching the video, the subjects were asked if they noticed anything odd; around half did not even notice the gorilla.
While most of us are confident in our ability to notice everything we see in front of us, Chabris’ experiment reveals that a lot of us experience inattentional blindness (also known as the “illusion of attention”).
Another person who gives us insight into what we see versus what we don’t see is Ulric Neisser, the father of cognitive psychology. One evening Neisser was looking out his window. He noticed that as he looked at the window he could either look out at the twilight or he could look at his reflection in the window. He could not, however, see both the twilight and his reflection at the same time. His term for this phenomenon was “selective looking” (2).
In a world and an age where we are bombarded by visual imagery, it’s good to know that we don’t truly see as much as we think we do. By being mindful of this fact we might learn to better distinguish between what it means to see versus what it means to observe.
In a passage from Sir Arthur Conan Doyle’s short story “A Scandal in Bohemia,” Sherlock Holmes asks Watson if he can recall the number of steps he climbed before entering the residence at 221B Baker Street. Although Watson had climbed the steps a hundred times, he confessed that he didn’t know the exact number.
Holmes’ response to Watson is instructive: “You have not observed. And yet you have seen. That is just my point. Now, I know that there are seventeen steps, because I have both seen and observed."
Recall, Retrieve, Recite, Ruminate, Reflect, Reason: What is inattentional blindness, and what does hit have to do with the difference between “seeing” and “observing”?
Challenge - Change and Choice Blindness: Two other phenomena related to attention and perception are change blindness and choice blindness. Do a bit of research on one of these two concepts. Define the concept, and explain what it can teach us about our ability to pay attention.
