The Machine Remembers & Man Forgets
The Screenshot as an Extension and Amputation of Memory
A Graduate Student of Technology asks:
Researchers at Binghamton University are reporting a curious effect they call the "digital capture effect": people who take screenshots of information may actually remember less of what they have saved. How can a technology that extends our ability to preserve information actually cause us to remember less of it?
Nelson S. Thall replies:
All technology is an extension of man, physically or psychically, and every extension produces an amputation that leaves the extended area numb. The reason is simple: when the machine assumes a human function, the human faculty is relieved of having to perform it. McLuhan warned that "self-amputation forbids self-recognition." We become numb precisely where the technology has extended us, and therefore fail to recognize what the extension is doing to us. The screenshot is a perfect example. It extends memory outside ourselves and into the machine. "I don't have to remember this because my phone will." The human memory function is therefore partially relieved, and consequently numbed. The extension produces the amputation, the amputation produces numbness, and pushed far enough the technology reverses into its opposite: the machine designed to preserve memory produces forgetting. The screenshot did not fail as a memory technology. It succeeded so completely that the user no longer had to remember.
