Suppose that you and your family are moving to a new apartment. Because your little brother has an excellent memory for things in general, he is put in charge of remembering what is packed with what. Because your mother usually takes care of bill payment, she is put in charge of remembering with what companies your family needs to file a change-of-address form. And because you have been the one handling most of the logistics of the move (hiring a company to inspect the new apartment for termites, making sure that you received your deposit back on your old apartment, etc.), you are put in charge of keeping track of these things. This is an example of ____.

The concept of transactional memory was developed by psychologist Daniel Wegner, stating that we not only store data in our own brain but also do so using other people's, more if they are close. We remember fewer data at the individual level but we know where this information is retained. The proposed situation shows us that knowing the person with whom we live well is very necessary to be sure of what are the things that each one deals with and to understand that everyone has a part of the information.
