href='//news-app-staging.herokuapp.com/stylesheets/article.css' type='text/css' /><div class='article'><p><span data-start-time='0' data-end-time='7729'>Did you ever wonder why you have no memory of when you were a baby or very young child?</span> <span data-start-time='7729' data-end-time='13188'>Researchers in the United States are investigating this question.</span> <span data-start-time='13188' data-end-time='20479'>The researchers work at Temple University in Philadelphia, Pennsylvania.</span> <span data-start-time='20479' data-end-time='30708'>The question of why adults do not remember how they learned to walk or talk has long been a mystery.</span> <span data-start-time='30708' data-end-time='36854'>Nora Newcombe is a psychology professor at the university.</span> <span data-start-time='36854' data-end-time='44396'>She joined Zoe Ngo, a Temple graduate student, in the memory research project.</span> <span data-start-time='44396' data-end-time='55458'>Newcombe says: “You know you learned how to walk and talk, but the funny thing is that you don’t remember when and how you learned this.”</span> <span data-start-time='55458' data-end-time='61313'>The Temple University study involved computer-based tests.</span> <span data-start-time='61313' data-end-time='65917'>The tests were designed to work like games.</span> <span data-start-time='65917' data-end-time='75458'>They were given to 32 four-year-olds, 32 six-year-olds and 50 young adults.</span> <span data-start-time='75458' data-end-time='84333'>The tests measured the memory process that helps people recognize differences between experiences.</span> <span data-start-time='84333' data-end-time='95333'>For example: A walk with your dog when you saw a friend, and a different walk without your dog or when you did not see your friend.</span> <span data-start-time='95333' data-end-time='105563'>“In order to remember those kind of autobiographical events, you need to relate one element to another,” Newcombe said.</span> <span data-start-time='105563' data-end-time='116042'>She notes that many people often take walks in a favorite park, but the experience might differ one day from another.</span> <span data-start-time='116042' data-end-time='125208'>Special memory skills are needed to remember when different events happen, like meeting a friend, she said.</span> <span data-start-time='125208' data-end-time='130479'>This differentiation is known as relational memory.</span> <span data-start-time='130479' data-end-time='141958'>This skill would also be important to remembering where you parked your car today, compared to where you left it yesterday or last week.</span> <span data-start-time='141958' data-end-time='149354'>The second test involved showing the test subjects a number of photographs.</span> <span data-start-time='149354' data-end-time='160083'>The children and young adults taking the test were asked to compare the first group of photos with a second set of pictures.</span> <span data-start-time='160083' data-end-time='165063'>Sometimes, the two sets of photos were the same.</span> <span data-start-time='165063' data-end-time='168583'>But other times, they were different.</span> <span data-start-time='168583' data-end-time='176625'>Remembering differences in objects, such as pictures, is known as pattern separation.</span> <span data-start-time='176625' data-end-time='186250'>The results showed that in both tests, six-year-olds demonstrated far better memory than 4-year olds.</span> <span data-start-time='186250' data-end-time='193271'>The six-year-olds performed about as well as the young adults on the two tests.</span> <span data-start-time='193271' data-end-time='202521'>The two tests suggest that memory skills are more advanced for six-year-olds than 4-year-olds.</span> <span data-start-time='202521' data-end-time='209417'>That might help explain why adults do not remember when they learned to walk or talk.</span> <span data-start-time='209417' data-end-time='215542'>But they do remember their third, fourth or fifth birthdays.</span> </p></div><div
