Despite helping to record events, photos could damage our memories. Researchers found people who take pictures have【C1】______remembering what actually happened. This phenomenon has been named 'photo-taking impairment effect'. From childrens birthdays to that long-awaited family holiday, we all want to remember those【C2】______moments with a photograph.【C3】______if youre one of those people who cant stop【C4】______beware then—you could【C5】______forgetting it all in a flash. A study has found that taking too many photos may prevent us from forming detailed memories. Researchers from Harvard University, the University of Wisconsin-Madison and Columbia University in the U.S. recently found that many people now use the Internet【C6】______a memory. They claimed that when someone wants to know something they now use the Internet【C7】______an 'external memory' just as computers use an external hard【C8】______. The study continued that we are now so【C9】______on smartphones and laptops, we go into 'withdrawal when we cant find out something【C10】______'. Far from helping us to【C11】______the moment, it could mean we miss whats going on right in front of our noses. Researchers led a group of students around a museum and asked them to either photograph or try to remember certain works of art and historical【C12】______. The next day, their memory was tested. It showed they were【C13】______at recognizing objects they had photographed than those they had only looked at. They were also poorer at【C14】______details of the objects they had taken pictures of. Dr Linda Henkel, who conducted the study at Fair field University in Connecticut, said: 'People so often【C15】______out their cameras almost mindlessly. When people rely on technology to remember for them, it can have a【C16】______impact on how well they remember their【C17】______.' Previous studies have suggested that【C18】______old photos can help us remember, but only if we spend long enough doing it. 'In order to remember, we have to【C19】______and interact with the photos, rather than just【C20】______them,' said Dr Henkel. 【C1】
