The Machines That Tested Our Attention

Today, many people worry about their attention. We often feel we cannot focus for very long. We constantly check our screens, notifications, and endless feeds.

An outsider might find this strange. They might think, "They have trouble focusing? But they stare at their phones all day!" This is the problem. We have no issue with the kind of focus our devices demand. We are experts at the sustained, reactive attention needed for machines. This cybernetic attention—our deep, machine-driven focus—is a key feature of modern life. What feels harder is human attention: the ability to be present with ourselves and others, to read a book, or to simply daydream without interruption.

This is not random. For over a century, scientists have studied human attention in labs. Their goal was to understand how people could operate machines, monitor radar, or shoot down planes. Psychologists measured how long someone could watch a dial or respond to a light. They wanted to quantify and improve our machine-focused abilities. To understand today's "attention economy," it helps to look back at this history. The type of attention studied in those labs is the same kind that is now measured and sold online, often with negative results.

This process started with a tool called the "pursuit test." It was part game, part experiment, and it brought man and machine together in the early 1900s. The photo shows an early version built by American psychologist Knight Dunlap during World War I. He wanted to test pilots. Dunlap believed a pilot's ability to focus was crucial for survival in combat. He wrote that psychology must study a flier's power "of sustaining attention" and handling multiple tasks at once.

Dunlap's device was an attention stress-test. A subject sat before a panel with fourteen lights and fourteen brass pins. When a light turned on, the person had to touch the matching pin with a metal stylus without touching the metal washer around it. It was like a difficult version of the game "Operation."

The test also included other tasks. The person had to keep a needle centered on a meter using a dial. At the same time, they had to keep a small motor running by pressing a foot pedal. For twenty-five minutes, a cadet would do all this while slowly being deprived of oxygen through a special mask. These experiments turned lab equipment into dynamic tools for measuring controlled focus.

Dunlap's device pitted a person against an experimenter. The next step was to automate the test. The most famous automated version was the "Pursuitmeter," invented by psychologist Walter R. Miles in the 1920s. Miles was known as a master creator of psychological gadgets.

His Pursuitmeter was a sophisticated feedback system. It trained people to work closely with a machine. At its center was a small screen with a vertical white line. A white dot moved left and right across the line in a programmed, random pattern.

The person being tested watched this dot. They used a control handle to try to keep the dot on the line. A paper recorder tracked how well they did. The goal was to keep the system "on target" for the entire test. In the photo, the subject is again in an oxygen-deprivation experiment, mimicking the conditions faced by early pilots. This machine created a strange dance of eye, hand, and mind.

You can think of it as a reverse situation. A pilot steers a plane reacting to the real world. In the Pursuitmeter, the machine "steers" the human through a set of programmed moves, testing the human's ability to follow. It simulates the basic problem of keeping something steady. In a way, it is a robotic game of Simon Says.

The Pursuitmeter, with its programmed movements and automatic recorder, was a fully automated testing system. It measured a person's ability to give sustained, focused attention to a machine's cue.

Looking at that subject, eyes glued to the cursor as his vision fades, we see a glimpse of our own future. We see ourselves, eyes glazed, sinking into the digital world. This was no accident. It is the result of a long history of putting humans in front of machines and asking them to keep up.

We worry about our attention today. But mostly, we worry about cybernetic attention—the kind tested by pursuit meters, with our eyes on a stimulus and our fingers ready to react. A direct line connects those old pilot-testing machines to the clicks and taps of our modern online life. These tests were part of psychology's effort to measure human capabilities.

Attention became a major focus. The type studied in labs was practical and operational—the kind you could measure with instruments. While important for the military, these tools found their biggest use in advertising. From devices that tracked what people listened to on the radio, to eye-tracking systems that measured what people looked at, the business of measuring attention became the engine of the attention economy.

Is all that quick, machine-focused scrutiny really "attention"? In a way, yes. You can call it attention, and scientists can write many papers about it because it is easy to measure. But reading a book is also an act of attention, and it is much harder to measure with numbers. Love is an act of attention, too, and it cannot be quantified at all.

How do we fix the "attention crisis" caused by today's technology? One way is to remember that cybernetic attention is just one kind. Human attention is something else entirely. We must learn to step away from the endless digital pursuit tests of modern life and see what we have been missing.
