In a new study, psychological scientist Linda Henkel of Fairfield University presents data showing that participants had worse memory for objects, and for specific object details, when they took photos of them…
Undergraduates were led on a tour around the museum and were asked to take note of certain objects, either by photographing them or by simply observing them. The next day, their memory for the objects was tested.
The data showed that participants were less accurate in recognizing the objects they had photographed compared to those they had only observed. Furthermore, they weren’t able to answer as many questions about the objects’ visual details for those objects they had photographed.
Henkel calls this the “photo-taking impairment effect”:
“When people rely on technology to remember for them — counting on the camera to record the event and thus not needing to attend to it fully themselves — it can have a negative impact on how well they remember their experiences,” she explains.
A second study replicated these findings, but it also presented an interesting twist: Taking a photograph of a specific detail on the object by zooming in on it with the camera seemed to preserve memory for the object, not just for the part that was zoomed in on but also for the part that was out of frame. read more

Tetsuro Matsuzawa begins his working day, conventionally enough, in front of a computer. He taps in a few commands, takes a seat and waits. Within minutes, the calm of his basement laboratory is pierced by the sound of excitable primates.
On cue, two chimpanzees appear through an opening in the ceiling, flash a look of recognition at Matsuzawa, and then aim an inquisitive stare at his unfamiliar companion from the Observer.
Matsuzawa feeds them a spoonful of honey each and wipes their hands and fingers – a near-daily ritual meant to reward them for arriving on time, and to encourage them to show up again the following morning.
After all, Ai, a 36-year-old chimpanzee, and her 13-year-old son, Ayumu, are free to stay in their nearby home, a re-creation of a west African rainforest they share with 12 other chimps. That they are such willing participants in Matsuzawa’s experiment is a tribute to the bond that has built up between the professor and the chimps during many years of research.
Over the course of more than three decades, Matsuzawa, a professor at Kyoto University’s Primate Research Institute in Inuyama, a historic town in central Japan, has gained unprecedented insights into the workings of the primate mind, and by extension, our own.
In a landmark test of short-term memory conducted in public in 2007, Ayumu demonstrated astonishing powers of recall, easily beating his human competitors, who had been in training for months.
The strength of Ayumu’s cognitive functions surprised even Matsuzawa, who has studied the mental dexterity of chimps for 36 years. He makes long annual visits to Bossou in south-eastern Guinea, where he witnesses chimps display in the wild the same powers of recognition and recall that Ayumu and other young chimps demonstrate on his computer screens.
“We’ve concluded through the cognitive tests that chimps have extraordinary memories,” Matsuzawa says. “They can grasp things at a glance. As a human, you can do things to improve your memory, but you will never be a match for Ayumu.” read more
