Memory is essential and crucial to learning. Learning a language requires a good memory. We use it in getting as many as possible vocabulary, learn grammar, etc. If we do not have a good memory it is difficult for us to learn language although it is our first language. The kind of simple memorization where words, phrases and sentences are remembered just as they are, is called ‘rote’ memorization (Danny, 1993: p207). The rote memory ability of very young children seems to be excellent in that they easily absorb a phenomenal amount of data. Based on the theory, memory is declined in some age. By 50, for example, there appears to be a decrease of about 20 per cent in the number of brain cells in the cortex; by 75 years of age that loss will have reached approximately 40 per cent (Danny, 1993: p207). It is a normal loss in all humans. To compensate this kind of decreasing of memory in adult age, adults usually develop some strategies in learning and seek for more practice and exposure.
