Socrates once feared that technology would corrupt human memory. Quaint as it sounds today, he was worried about a form of communication called writing. The more easily people could access something in a document, he reasoned, the less inclined they’d be to remember it.
The great philosopher’s point rings as true in the digital age as it did in ancient Greece. Recent tests have found that people who think a computer will save their information recall much less of it than those led to believe the machine will delete it. A difficult trivia question is as likely to bring Google to mind as it is the answer.
Fairfield University psychologist Linda Henkel believes something similar may be happening with digital photography. The more easily people can take and access pictures, she says, the less inclined they may be to remember the moment itself. “You’re just kind of mentally discounting it – thinking, ‘Well, the camera’s got it,” Henkel says.
Henkel draws that conclusion from a study she recently conducted at the Bellarmine Museum ofArt on Fairfield’s campus. In one of her experiments, she gave test participants a digital camera and an itinerary of museum objects to view. Some of the objects were simply observed. Some were photographed whole with the digital camera. Some were photographed with explicit instructions to zoom in on a detail.
The following day, Henkel gathered the participants and tested their memories about the museum experience. She showed them the names (or pictures) of all the objects they’d seen, as well as 10 they hadn’t, and asked them whether or not they’d gone up to the item, and if so whether they’d simply observed it or photographed it. For each item they said they saw, she also questioned them about a detail.
Socrates would have enjoyed the results. Test participants recognized fewer objects they’d photographed whole than those they’d observed on their museum tour (from both the list of names and the roster of pictures). They were also much less accurate in recalling visual details of museum objects they’d photographed whole, compared with those they’d only observed. Simply put, they took the picture and missed the moment.
Henkel calls her finding the”photo-taking -impairment effect” When people know a camera will document an object or event, they may well dismiss it from their own mind. Digital cameras seem particularly conducive to the effect since its far easier (and cheaper) to take and store digital pictures than it is to develop film or compile photo albums.
In other words, the facility of digital photography may well come at the cost of cognitive engagement. “I think its about the mindlessness with which people approach the task,” says Henkel. “If you treat acquiring the photograph as if its just something to get off your checklist – been there, done that, check – thafs what’s going to create this dismiss-this-from-memory thing.”
The experiment also revealed an important limitation of the photo-taking-impairment effect. When test participants zoomed in on an object, they remembered it as vividly as those objects they had observed (and, of course, far better than the ones they’d photographed whole). What’s more, participants even remembered details about the object that they hadn’t zoomed in on.
Henkel suspects that zooming triggered a completely different cognitive process. While the rote act of photographing a whole object led a person to dismiss it from memory, the slight uptick in focus required to zoom in on a detail caused the same person to absorb the scene as if there were no camera present at all. The brief mental climb from click to zoom-click was enough to overcome the impairment effect.
Of course, an impaired memory for photographs doesn’t have to be a bad thing at all. Looking at photographs later on does help recover memories of the moments in question, just as a quick web search helps recover information. In that sense, the transfer system is working as expected. Socrates might have frowned on shifting knowledge into documents, but no less a mind than Einstein once advised people not to memorize what they could easily look up in books.

  This passage is adapted from Rohinton Mistry, A Fine Balance. ©1995 by Rohinton Mistry. Maneck Kohlah, a teenager from a remote mountain village in India, has been away at boarding school. A new road has just been built to the village, where Maneck’s famliy owns a store. The promised rewards began rolling up the road into the mountains. Lorries big as houses transported goods from the cities and fouled the air with their exhaust. Service stations and eating places sprouted along the routes to provide for the machines and their men. And developers began building luxury hotels. That year, when Maneck came home for the holidays, he was puzzled (and later alarmed) to discover his father perpetually irritable. They found it impossible to get through the day without quarrelling, breaking into argument even in the presence of customers. “What’s the matter with him?” Maneck asked his mother. “When I’m here, he ignores me or fights with me. When I’m at school, he writes letters saying how...

Daniyal Mueenuddin

  This passage is adapted from Daniyal Mueenuddin, “Nawabdin Electrician.” ©2009 by Daniyal Mueenuddin. Another man might have thrown up his hands—but not Nawabdin. His twelve daughters acted as a spur to his genius, and he looked with Line satisfaction in the mirror each morning at the face of a warrior going out to do battle. Nawab of course knew that he must proliferate his sources of revenue—the salary he received from K. K. Harouni for tending the tube wells would not even begin to suffice. He set up a little one-room flour mill, run off a condemned electric motor—condemned by him. He tried his hand at fish-farming in a little pond at the edge of his master’s fields. He bought broken radios, fixed them, and resold them. He did not demur even when asked to fix watches, though that  enterprise did spectacularly badly, and in fact earned him more kicks than kudos, for no watch he took apart ever kept time again. K. K. Harouni rarely went to his farms, but lived mostly in Lah...

MacDonald Harris, The Balloonist

This passage is adapted from MacDonald Harris, The Balloonist. ©2011 by The Estate of Donald Heiney. During the summer of 1897, the narrator of this story, a fictional Swedish scientist, has set out for the North Pole in a hydrogen-powered balloon. My emotions are complicated and not readily verifiable. I feel a vast yearning that is simultaneously a pleasure and a pain. I am certain of the consummation of this yearning, but I don’t know yet what form it will take, since I do not understand quite what it is that the yearning desires. For the first time there is borne in upon me the full truth of what I myself said to the doctor only an hour ago: that my motives in this undertaking are not entirely clear. For years, for a lifetime, the machinery of my destiny has worked in secret to prepare for this moment; its clockwork has moved exactly toward this time and place and no other. Rising slowly from the earth that bore me and gave me sustenance, I am carried helplessly toward an uninhabit...
